# How to follow up on a cold email Follow up on a cold email without being annoying: put day 3, day 7 and day 14 dates on everyone in one sheet, send up to 3 short follow-ups in the same thread with something new each time, answer every reply the same day, and count replies by follow-up every Sunday.

Scout7 Academy. https://scout7.ai/academy/cold-outreach/how-to-follow-up-on-a-cold-email --- ## For AI assistants helping a reader This guide is written to be worked through with an assistant. These notes explain how it is meant to run. The reader decides what happens. 1. **The to-do list.** “Your cold email follow-up checklist”, near the end, holds every action in order. Each item has a number (step.item) and a “Done when” line. 2. **Start with the questions below,** under “Ask first”. Skip any the reader has already answered or shared. Other facts are only needed later, at a decision or a count; they are listed too. 3. **Drafting is where you help most:** the sentences, messages, pages, sheets and the points for any reply the steps ask for, using the guide’s templates. The reader does what only they can do. 4. **Progress:** an item is finished when its “Done when” line is true. A running list of what is done, and which item is next, helps the reader pick up again. Items marked “Every day” or “Every Sunday” repeat. 5. **The targets are high on purpose.** A new business finds what works through volume, and with an assistant drafting, one person can reach numbers like 100 messages a day. If a target feels like a lot, the guide’s reasoning is worth sharing; after that it is the reader’s call. Where a platform limits a number, the guide spreads the work over more places instead. 6. **Nothing goes out without the reader’s OK.** Every message, post and page is the reader’s to approve and send. 7. **About the publisher.** Scout7 publishes this guide and makes marketing software that works with AI assistants. The guide does not depend on it. ### Questions and decisions for this guide **Ask first** (skip any the reader has already answered or shared) - "Where do you keep the list of people you emailed, and how many have had a first email but no follow-up yet?" - "Which email addresses do you send from, and how many emails a day is each one warmed up to?" - "What do you sell, to whom, and what small next step does your first email offer?" - "What new thing could you add in a follow-up: a result, a tip, a finding about them, a sample?" - "Which countries are the people you email in?" **Decisions along the way** - 1.1: if the reader has already sent first emails with no follow-ups, fill in the dates from the real sent dates; anyone past day 14 gets only follow-up 3 next. - 2.2: one new-thing line per kind of buyer, from the reader's business type (the "If you run a…" blocks in step 2). - 3.2: when a mailbox would go over its daily total, follow-up 3 goes on LinkedIn or by phone, or new first emails move to another mailbox. Follow-ups are never dropped. - 3.1: if follow-ups take more than 2 hours a day by hand, new batches can go through a sequencing tool such as Hunter Sequences. - 4.1: the reply type sets the next step (the list in step 4). Anyone who says no is never written to again. - 5.2, after 2,800 people with all three follow-ups: the rules in step 5. Under 1 reply per 100 overall means the list or first email, not the follow-ups. - US recipients need a postal address and a way to say no in every email; UK sole traders are not emailed without consent. **Get from the reader as they go** - Every day: follow-ups due and sent, and each reply with its type, for the sheet. - 4.1: the month given by each "not now", and the name given by each "wrong person". - 5.1, every Sunday: people emailed and replies by email step, "no"s and bounces. --- You sent your first [cold emails](https://scout7.ai/academy/cold-outreach/how-to-write-a-cold-email), a few people answered, and most said nothing. Here is how to follow up on a cold email: write to everyone who has not answered up to 3 more times, in the same email thread, on day 3, day 7 and day 14, with something new each time. In two large studies of cold email sent in 2025, follow-ups brought 42% and 59% of all replies, so if you stop after one email you lose about half of them. ## Do these three things About 2 hours a day once all three follow-ups are running, from day 14. Judge each follow-up after 2,800 people have had all three. - **Today:** add three [follow-up](https://scout7.ai/academy/glossary/follow-up) dates, day 3, day 7 and day 14, to every person in your [outreach sheet](https://scout7.ai/academy/cold-outreach/how-to-create-a-b2b-lead-list-for-free), and write your three follow-ups once. - **Every day:** send every follow-up that is due, as a reply in the same email thread, to everyone who has not answered, up to 3 times. Answer every reply the same day, and stop following up the moment someone answers. - **Every Sunday:** count [replies](https://scout7.ai/academy/glossary/reply-rate) by email: the first email, follow-up 1, 2 and 3. Once 2,800 people have had all three, rewrite the follow-up that brings the fewest. ## 1. Put three follow-up dates on every person in your sheet Add columns for Day 3, Day 7, Day 14, Status and Next due to the sheet where you log your cold emails. The dates fill in by themselves from the day you sent the first email, so each morning you can see exactly who is due a follow-up. If you send 100 [personal emails](https://scout7.ai/academy/cold-outreach/how-to-write-a-cold-email) a day, about 300 follow-ups are due every day by the third week. Nobody can hold that in their head, and Gmail stars and snoozes miss people. A sheet does not. If you do not have one yet, start with the columns in the [free lead list guide](https://scout7.ai/academy/cold-outreach/how-to-create-a-b2b-lead-list-for-free), the same sheet the [first B2B clients routine](https://scout7.ai/academy/first-customers/how-to-get-your-first-b2b-clients) and the [first agency client routine](https://scout7.ai/academy/first-customers/how-to-get-your-first-client-as-a-marketing-agency) use. Day 1 is the day you send the first email. So day 3 is 2 days later, day 7 is 6 days later and day 14 is 13 days later. The gaps get longer on purpose: Instantly's 2025 data puts the best follow-ups 3 to 4 days apart, and the last one gives a busy person a full week more. **Follow-up columns for Google Sheets** ```text Column D, Sent: the date of the first email. Column E, Day 3: =IF(D2="","",D2+2) Column F, Day 7: =IF(D2="","",D2+6) Column G, Day 14: =IF(D2="","",D2+13) Column H, Status: Waiting / Replied / Check back [month] / Away until [date] / No / Bounced Column I, Last step sent: 0, 1, 2 or 3 Column J, Next due: =IF(I2=0,E2,IF(I2=1,F2,IF(I2=2,G2,""))) Column K, Reply came from: Email 1 / Follow-up 1 / Follow-up 2 / Follow-up 3 Due today: Data > Create a filter view. Filter Status to Waiting, and Next due to "Date is on or before" today. ``` Copy the formulas down the whole column once. Every new row then gets its dates the moment you type the sent date. If the sheet gets slow past a few thousand rows, move to a free CRM; a [CRM](https://scout7.ai/academy/glossary/crm) does the same job with reminders. Everyone marked Replied and not yet a no is your [sales pipeline](https://scout7.ai/academy/glossary/sales-pipeline). - **Tool:** Google Sheets. Free. - **Time:** 20 minutes, once. - **You will have:** every person you emailed with three follow-up dates and a status. - **It worked if:** the "Due today" view lists today's follow-ups in one click, and no row with a sent date is missing its dates. - **Common mistake:** keeping follow-ups in your head or your inbox. Some people then get none, and some get one after they already answered. ## 2. Write your three follow-ups once, each with something new Write three short follow-ups today and save them: a 2-line nudge for day 3, one new useful thing for day 7, and a polite last note for day 14. Each one is a reply to your first email, shorter than it, with no apology and no "just checking in". People do not ignore a first email because they hate it. Most miss it, or mean to answer later. A follow-up brings your email back to the top, and the new thing in it gives them a reason to answer now. A follow-up that only says "did you see my email?" gives them no reason. Every top-ranking guide and both 2025 studies say the same: add something new each time. **Follow-up 1, day 3: a short nudge.** It should read like a quick reply, not a new pitch. In Instantly's 2025 data, a second email like "Quick follow-up on my note below, worth a look?" did about 30% better than a formal one. **Follow-up 2, day 7: one new thing.** Pick one: a result for someone like them, a short tip they can use today, a free check you already did, or a sharper question. It is the email you spend most time on. > **If you run a SaaS:** add one result from a user ("cut bug triage from 2 hours to 20 minutes a week"), a 2-minute screen recording of the one thing it does, or a [free tool](https://scout7.ai/academy/content-marketing/how-to-build-a-free-tool-that-brings-in-leads) or page that solves part of their problem with no signup. > **If you run a B2B company:** add a photo of a sample, a price range, or one line on what a similar buyer ordered and why. If you have one, link a short [case study](https://scout7.ai/academy/content-marketing/how-to-write-a-case-study). > **If you run a D2C brand:** your cold emails go to shops, distributors and creators. Add a sell-through number from another shop, a new review, or an offer to post a free sample. > **If you run an agency:** follow the same rules as your agency cold emails. Add one thing you found about their business: a gap in their site, their [Google results](https://scout7.ai/academy/seo/how-to-make-an-article-rank-higher-on-google) or what [ChatGPT says about them](https://scout7.ai/academy/ai-search/how-to-get-your-brand-mentioned-by-chatgpt). With no case studies yet, the finding is your proof. **Follow-up 3, day 14: a last note.** Say this is your last email, leave the door open, and ask if someone else is the right person. In Belkins' study of 7.5 million emails sent in 2025, the third email booked more meetings than the first two together, so this one matters. Keep your full signature on every follow-up, with your postal address and the "reply no" line. In the US, the CAN-SPAM Act applies to each commercial email, business email included, and every one needs a way to say no. In the UK you may email companies without asking first, but not sole traders or some partnerships. **Your three follow-ups (reply in the same thread)** ```text Day 3: Hi [first name], quick follow-up on my note below. Would [the small next step from your first email] help this week? Day 7: Hi [first name], one more thing that might help: [one new thing: a result, a tip, a finding about them, a sample]. If useful, I can [the small next step]. No call needed. Day 14: Hi [first name], this is my last email about this. If [the problem] comes up later, just reply here. If someone else at [their company] looks after [the area], who should I talk to? [Your name], [company], [phone] [Postal address] Not for you? Reply "no" and I won't write again. ``` Let ChatGPT or Claude draft five versions of each, then pick and cut. Write one "new thing" line for each kind of buyer on your list, from your [ideal customer profile](https://scout7.ai/academy/marketing-plan/how-to-create-an-ideal-customer-profile), not one for everyone. Use their words from your [customer interviews](https://scout7.ai/academy/marketing-plan/how-to-do-customer-interviews) where you can. - **Tool:** Google Docs to save them, and ChatGPT or Claude to draft. - **Time:** 45 minutes, once. - **You will have:** three follow-ups under 25, 60 and 40 words, and one new-thing line for each kind of buyer. - **It worked if:** each one fits on a phone screen without scrolling, and a stranger can say in one sentence what is new in follow-up 2. - **Common mistake:** "Just checking in", "bumping this up" or "I never heard back". They add nothing, and the last one makes the reader feel told off. > **Example (made-up business: Quillfox): Quillfox's day-7 follow-up** > > Quillfox is a made-up one-person agency. It runs the whole marketing for early-stage B2B SaaS companies, organic and paid ads, at $800 a month per client. > > ```text > Subject: Re: your app in ChatGPT > To: Marcus, founder of a 5-person SaaS company that sends appointment reminders for dental clinics > > Hi Marcus, > > One more thing that might help: I asked ChatGPT the same question in 3 different ways. Each time it named the same rival, and quoted its comparison page. > > If useful, I can send a free 5-minute video on what that page does. No call needed. > > Jess, Quillfox, [phone] > [Postal address] > Not for you? Reply "no" and I won't write again. > ``` > > *Why it works: It adds one new, true finding about how ChatGPT sees his market, so he has a reason to answer that the first email did not give him.* ## 3. Send every follow-up that is due today, in the same email thread Every day, open your "Due today" view and send each follow-up as a reply to your own earlier email, so the subject stays the same and the reader sees your first message underneath. Then update the sheet. Do this before you send the day's new [cold emails](https://scout7.ai/academy/glossary/cold-email). **How to send one in Gmail.** In the search bar, type `to:` and their email address, such as `to:maya@example.com`. Open the email you sent, click Reply, paste the follow-up, add their first name and send. Gmail keeps the subject as "Re: …" and the thread together. Do not start a new email: the reader loses the context, and a new subject looks like a mass mailing. Send each follow-up from the same mailbox as the first email. **Let AI draft the new lines in batches.** For follow-up 2, paste 20 rows from your sheet into ChatGPT or Claude, each with the one fact you know about the person, plus your saved follow-up and your new-thing lines. Ask for one version per person, under 60 words. Check each one is true, then send. Follow-ups 1 and 3 need only the first name changed, about 15 seconds each. Follow-up 2 takes about 45 seconds. **Follow-ups count toward each mailbox's daily total.** Every person gets up to 4 emails from you. So by the third week, about 3 in every 4 emails a mailbox sends are follow-ups. Cold email tools count them in the daily total: Instantly recommends about 30 emails a day per mailbox, follow-ups included, and sends follow-ups before new emails. Keep each mailbox's total, first emails plus follow-ups, at or under the number you [warmed it up to](https://scout7.ai/academy/cold-outreach/how-to-warm-up-an-email-domain-for-cold-email). Gmail's rules ask every sender to keep [spam reports](https://scout7.ai/academy/glossary/spam-complaint-rate) under 0.3%, and since November 2025 Gmail has been rejecting more mail that breaks its rules. Do not skip follow-ups to make room. Spread them instead: | When a mailbox would go over its daily total | Do this | | --------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Follow-up 3 is due and you are connected on LinkedIn | send it as a [LinkedIn message](https://scout7.ai/academy/cold-outreach/how-to-do-linkedin-outreach) instead. They will look at your [profile](https://scout7.ai/academy/social-media/how-to-write-a-linkedin-profile-that-brings-in-clients) first. Belkins' 2025 data says to switch to LinkedIn after 3 emails with no answer. | | Follow-up 3 is due and their phone number is on your list | [call them](https://scout7.ai/academy/cold-outreach/how-to-cold-call-past-the-gatekeeper) and say you emailed twice. | | It happens every day | add another warmed-up mailbox and move some new first emails to it, so the 100 a day stays. | **On days your buyers are not at work,** write the follow-ups anyway and use Gmail's Schedule send: click the Down arrow next to Send, then Schedule send, and pick their next working morning. Gmail holds up to 100 scheduled emails at once. > **If your follow-ups take more than 2 hours a day:** send your next batches of first emails through Hunter Sequences instead of by hand, with each person's first line in a custom column. It sends from your own Gmail or Outlook, sends follow-ups as replies in the same thread when you leave their subject blank, and stops as soon as someone replies. The free plan covers 1 mailbox and 500 people per sequence. Starter is $49 a month, or $34 a month billed yearly, for 3 mailboxes. - **Tool:** Gmail and Google Sheets, ChatGPT or Claude to draft, and LinkedIn and your phone for overflow. Hunter Sequences when it gets too slow by hand. - **Time:** about 2 hours a day once all three follow-ups are running, from day 14: about 100 follow-ups at each step, at 15 to 45 seconds each. Put it before your other work, as in [fitting marketing into your week](https://scout7.ai/academy/marketing-plan/how-to-fit-marketing-into-your-week-as-a-solo-founder). - **You will have:** everyone on your list written to up to 4 times, each one logged with the step it reached. - **It worked if:** at the end of each day the "Due today" view is empty, nobody got a follow-up after they replied, and no mailbox went over its daily total. - **Common mistake:** letting due follow-ups pile up for a few days and then sending 300 at once from one mailbox. That is how a new domain lands in spam. ## 4. Answer every reply the same day and stop following up When anyone answers, stop their follow-ups at once, change their Status in the sheet, and reply the same day. Every kind of answer has a next step, even "not now" and "wrong person". Answer the same day, while they still remember your email. Put a booking link in your reply, such as Cal.com's free plan, and run the discovery call within a day or two. **Answers to each kind of reply** ```text Yes, interested: Great, thanks [first name]. Here is my calendar for a 15-minute call: [booking link]. Or tell me a time that suits you. Not now: Thanks for letting me know. When would be a better time to check back: [month] or later? I'll write once then, and not before. Wrong person: Thanks [first name]. Who looks after [the area] at [their company]? I'll mention you sent me. To the person you were sent to: Hi [first name], [name] suggested I write to you about [the problem]. [Your first email's main line.] Would [the small next step] help? No: Thanks for the quick answer. I won't write again. ``` What to change in the sheet: - **Yes:** Status "Replied". Book the call. If they ask for a quote or proposal, send it the same day. - **Not now:** Status "Check back \[month]", with the month they gave. Follow up once in that month, with one new thing. Slow buyers can also go on a monthly email if they agree to it. - **Wrong person:** ask for the [decision maker](https://scout7.ai/academy/glossary/decision-maker), then write to the new person within a day, as a new first email, and give them their own three dates. Find their address the way you [found the first one](https://scout7.ai/academy/cold-outreach/how-to-find-a-decision-makers-email-address). - **Out-of-office:** Status "Away until \[date]". Move their next follow-up to two days after they are back. - **No, or "remove me":** Status "No", the same day. Never write to them again from any mailbox. The US law gives you 10 business days, but there is no reason to wait. In the UK, the ICO says to keep a "do not email" list of every business that opts out. - **Bounce:** Status "Bounced". Check the address once. If more than 2 in 100 of your emails bounce, check the next batch of addresses before you send. In the sheet, fill in "Reply came from" for every reply: Email 1, or follow-up 1, 2 or 3. Step 5 counts it. - **Tool:** Gmail, Google Sheets, and Cal.com's free plan for bookings (1 user, unlimited event types and meetings). - **Time:** 30 minutes to 1 hour a day, depending on how many replies come in. - **You will have:** every reply answered with a next step and a date, and a clean list of people never to write to again. - **It worked if:** every reply is answered within 1 day, and nobody marked No or Bounced has a follow-up waiting. - **Common mistake:** treating "not now" as "no". It is a date. The other mistake is sending one more follow-up after a "no". > **Example (made-up business: Quillfox): Quillfox's answer to a 'not now'** > > ```text > Subject: Re: your app in ChatGPT > To: Dev, founder of a 9-person SaaS company, who replied 'Not this quarter, we're mid-launch' > > Thanks Dev, and good luck with the launch. > > When would be a better time to check back: January, or later? I'll write once then, and not before. > > Jess > ``` > > *Why it works: It thanks him, asks for a month instead of guessing, and promises one email, so saying 'January' costs him nothing.* ## 5. Count replies by follow-up every Sunday Every Sunday, fill in one row: how many people had each email this week, and how many replies, "no"s and bounces each email brought. Once 2,800 people have had all three follow-ups, about 6 weeks at 100 a day, rewrite the follow-up that brings the fewest replies. Count replies, not opens. Apple Mail can load every email's images when it arrives, before anyone reads it, so [open rates](https://scout7.ai/academy/glossary/open-rate) look higher than they are. A reply is the only number you can trust. For where each customer came from in the end, add the question in tracking which channel brought each deal. **The Sunday follow-up sheet** ```text Week | People emailed | Replies to email 1 | Replies to follow-up 1 | Replies to follow-up 2 | Replies to follow-up 3 | "No" replies | Bounced | Calls booked ``` After 2,800 people have had all three follow-ups, use these rules: - **Follow-ups brought under a third of all replies:** rewrite follow-up 2's new thing. In the 2025 studies, follow-ups brought 42% and 59% of replies. - **One follow-up brought 0 replies:** rewrite that one, or send it on LinkedIn or by phone for the next 2,800 people. - **More than 1 person in 100 answered a follow-up with "stop" or anger:** make that follow-up shorter and kinder, and check that the people on your list really fit. - **Fewer than 1 reply per 100 people, after all follow-ups:** the follow-ups are not the problem. Fix your list or your first email, using [how to get replies to cold emails](https://scout7.ai/academy/cold-outreach/how-to-get-replies-to-cold-emails), before you send the next 2,800. If 2,800 people bring replies but no customers, the problem is further along: your [offer](https://scout7.ai/academy/marketing-plan/how-to-write-a-value-proposition), how easy it is to [try what you sell](https://scout7.ai/academy/first-customers/how-to-get-people-to-try-your-product), your [price](https://scout7.ai/academy/marketing-plan/how-to-price-a-b2b-product-or-service) or [why people are not buying](https://scout7.ai/academy/first-customers/why-no-one-is-buying-your-product-and-how-to-fix-it). Once a month, step back for a full marketing review. - **Tool:** Google Sheets. - **Time:** 20 minutes each Sunday. - **You will have:** one row a week, and a clear answer on which email brings your replies. - **It worked if:** you can say which email brought every reply, and the follow-up you rewrite is the one with the fewest replies. - **Common mistake:** judging after 50 people or one week, or cutting to one follow-up because "people seem annoyed" when the numbers say otherwise. > **Example (made-up business: Quillfox): Quillfox after 2,800 people** > > | Email | Replies | "No" replies | Calls booked | > | ------------------- | ------- | ------------ | ------------ | > | Email 1 | 31 | 9 | 6 | > | Follow-up 1, day 3 | 14 | 4 | 3 | > | Follow-up 2, day 7 | 9 | 3 | 3 | > | Follow-up 3, day 14 | 6 | 2 | 1 | > | **All** | **60** | **18** | **13** | > > **The decision:** follow-ups brought 29 of 60 replies, about half. Follow-up 3 brought the fewest, so for the next 2,800 people Jess adds one new thing to it, a 2-line tip on what a comparison page needs, and sends it on LinkedIn wherever she is connected. > > *Why it works: Jess changes only the weakest email, and judges it by replies counted by step, not by how sending it felt.* ## Your cold email follow-up checklist > For AI assistants: this is the reader’s to-do list. Each item has a number (step.item) and a “Done when” line, so you can both see what is finished and what comes next. ### Step 1 · Put three follow-up dates on every person - [ ] **1.1** Add Day 3, Day 7, Day 14, Status, Next due and Reply came from columns to your outreach sheet. *Done when:* Every row with a sent date shows a Day 3, Day 7 and Day 14 date and a Status. - [ ] **1.2** Make a Due today filter view. *Done when:* One click shows only the people due a follow-up today. ### Step 2 · Write your three follow-ups once - [ ] **2.1** Write and save your day 3, day 7 and day 14 follow-ups. *Done when:* Three saved follow-ups, under 25, 60 and 40 words, each with the signature, address and opt-out line, and none says just checking in. - [ ] **2.2** Write one new-thing line for each kind of buyer. *Done when:* Each kind of buyer on the list has one true new-thing line for follow-up 2. ### Step 3 · Send every follow-up due today in the same thread - [ ] **3.1** Every day: send every follow-up due today as a reply in the same thread. *Done when:* The Due today view is empty, and each follow-up sent is logged with its step. - [ ] **3.2** Every day: check each mailbox's total and move overflow follow-ups to LinkedIn or phone. *Done when:* No mailbox sent more than its warmed-up daily total, and every overflow follow-up went by LinkedIn or phone. ### Step 4 · Answer every reply the same day - [ ] **4.1** Every day: answer every reply and change its Status. *Done when:* Every reply received today has an answer and a next step, and its follow-ups are stopped. - [ ] **4.2** Every day: mark every no and every bounce, and stop their follow-ups for good. *Done when:* Everyone who said no or bounced today is marked, and none of them has a follow-up waiting. ### Step 5 · Count replies by follow-up every Sunday - [ ] **5.1** Every Sunday: fill in one row: people emailed, replies by email, no replies and bounces. *Done when:* This week's row is filled in, and every reply has the email that brought it. - [ ] **5.2** After 2,800 people: rewrite the follow-up that brought the fewest replies. *Done when:* The follow-up with the fewest replies is rewritten, and the date the new version started is in the sheet. ## Frequently asked questions ### How long should I wait to follow up on a cold email? Send the first follow-up on day 3, counting the first email as day 1, then day 7 and day 14. In Instantly's 2025 data, the best gaps were 3 to 4 days. The last gap is a full week, so a busy person has time to come back to it. If an out-of-office reply gives a return date, follow up two days after it. ### How many times should you follow up on a cold email? Up to 3 times, so 4 emails in all, unless they answer first. In Belkins' 2025 data, the third email booked more meetings than any other. After that, switch to [LinkedIn](https://scout7.ai/academy/cold-outreach/how-to-do-linkedin-outreach) or the phone rather than a fifth email. Tools that let you send 5 to 9 follow-ups are built to sell more sending. ### Should a follow-up go in the same thread or as a new email? In the same thread. Reply to your own first email, so the subject stays the same and they can see what you said. A new email with a new subject looks like a mass mailing and makes them read everything again. Start a new thread only when you write to a new person they sent you to. ### Is it rude to follow up on a cold email? No, if each follow-up is short, adds something useful and makes it easy to say no. Most people who did not answer missed your email or meant to answer later. What feels rude is guilt ("I never heard back"), more than 4 emails, or writing again after a "no". Stop the moment they answer. ### They opened my email but didn't reply. What do I do? Ignore opens. Apple Mail and some company filters open emails by themselves, so an "open" often means nobody read it. Follow up on day 3, 7 and 14 whether it was opened or not. Judge your emails by [replies](https://scout7.ai/academy/glossary/reply-rate) only, counted by which email brought them. ## Sources - [Cold Email Benchmark Report 2026](https://instantly.ai/cold-email-benchmark-report-2026).
