How to nurture B2B leads by email

Some people asked for a quote, said "not now" to your cold email or took your card at a show, and then went quiet, because a business buyer can take months to decide. To nurture B2B leads by email at this size, ask each lead when they will decide, then send them one short, useful email every 14 days from your own inbox until they are ready. If you send nothing, they will most likely buy from a supplier they already know: in a 2025 survey of nearly 4,000 business buyers, the supplier that won was on their first shortlist 95% of the time.

Do these three things

About 5 hours to set up today, then 20 to 40 minutes a day and 30 minutes on Sunday. Judge each email after 50 sends, and the whole list after 500.

Show the three actions in fullHide the full list

1. 1Today: put every lead who has not bought or said no into one sheet, and send each one a short personal email asking when they will decide and what has to be true first. AI drafts it; you add one true line about what they asked.
2. 2Every day: add each new lead the day they come in, send every nurture email that is due (one useful email every 14 days for each lead), and answer every reply the same day. When a lead is ready, offer a 15-minute call, a sample or a quote.
3. 3Every Sunday: count replies, calls and quotes from the list by name, write one new nurture email from the question buyers asked most this week, and rewrite any email that got no replies after 50 sends.

1. Put every lead who has not bought yet into one nurture list

Your nurture list is every person who has shown interest in the last 12 months but has not bought and has not said no. Put them all in one sheet today, with one row each.

Look in these places, and add everyone you find:

• Quotes and proposals that got no answer. Your proposals folder and sent mail have them.
• "Not now" replies to your cold emails and LinkedIn messages: "maybe next quarter", "send me something", "not the right time".
• Calls and demos that went quiet after a discovery call or a demo.
• People you met at a trade show or a networking event, and people who joined your webinar.
• Sample requests and website enquiries, including anyone who downloaded a free guide or tool from your site.

Give each person one row with these columns: name, email, company, role, where they came from, what they asked, why they are waiting, decide-by date, last email, next email, and status. Leave "why waiting" and "decide by" blank for now. Step 2 fills them in.

Take four kinds of people out:

• Anyone who said no or asked you to stop. Keep them on a separate "do not email" tab. The UK regulator asks businesses to keep this kind of list.
• Anyone whose email bounced. Find the right address with the steps for finding a decision maker's email, or leave them out. Bounces hurt your email deliverability.
• Anyone who bought. They are customers now. Thank them, and later ask for a testimonial. If they go quiet after their first order, send them a win-back email instead.
• Cold contacts who never replied. They stay in your follow-up sheet. A nurture email goes only to people who have talked to you.

Check one rule before you email anyone. In the UK, you may email a person at a company, but sole traders and some partnerships count as people, and they need to have agreed first. If your buyers are in the EU, check that country's rules first.

The list only works if new people keep joining it. Aim for at least 20 new leads a week. If you get fewer, the fix is more outreach, not more nurture: send 100 personal messages a day to people who fit your ideal customer profile, from your lead list.

• Tool: Google Sheets. If you already moved to a CRM, use it instead, with the same fields.
• Time: 1 hour.
• You will have: one sheet with every lead who has not bought or said no, one row each.
• It worked if: everyone who asked about you in the last 12 months, and has not bought or said no, is in it, and nobody who said no is.
• Common mistake: pasting your whole cold list in. People who never answered you did not ask to hear from you, and a "nurture" email to them is a cold email with no point.

2. Ask each lead when they will decide and what has to be true first

The first nurture email asks two questions: when the lead expects to decide, and what has to be true before they do. Their answers tell you which email to send next and when to offer a call.

Write it the way you would write to one person. Keep it under 80 words and use these parts:

1. A subject line like a personal email: their first name and what they asked about, in lower case.
2. One true line about what they asked, and when.
3. The two questions: when will you decide, and what has to be true first?
4. One permission line: can you send one short, useful email every 2 weeks until then? "Reply no and I'll stop."
5. Your name and your postal address. US law needs the address, even for emails to businesses (step 4).

Subject: [first name], your [what they asked about]Hi [first name],In [month] you asked about [what they asked]. [One true line: what it was for, or what you sent them.]Two quick questions: when do you think you'll decide on [the thing], and what has to be true before you do?Until then, can I send you one short, useful email every 2 weeks, like [one topic from step 3]? Reply "no" and I'll stop.[Your first name]
[Your business, postal address]

Use ChatGPT or Claude to write the true line for each person. Paste in 10 rows at a time from your sheet, with the template, and ask for one email per person. Read each draft and check every line is true. Then send it from your normal email address, one at a time. That is about 3 minutes an email, so 30 leads take about an hour and a half.

Most people will not answer the first time. Follow up up to 3 times, on day 3, day 7 and day 14, as replies in the same thread, the same way you follow up on a cold email. Each follow-up is one or two lines. Never "just checking in".

When someone answers, write their reason in "why waiting", using one of five words: timing, budget, sign-off (someone else decides), comparing (they are looking at other suppliers), or unknown. Write their date in "decide by". If they say no, move them to the "do not email" tab.

• Tool: Gmail or your work email, your sheet, and ChatGPT or Claude to draft.
• Time: about 3 minutes an email. About 1.5 hours for 30 leads, plus the follow-ups.
• You will have: an email sent to every lead, and a reason and a date for everyone who answered.
• It worked if: every row has a sent date, and every answer is in the sheet the day it arrives.
• Common mistake: asking for a meeting in this email. A lead who is not ready says no to a meeting, but will tell you their date.

3. Write six nurture emails that each answer one buyer question

A nurture email answers one question your buyers really ask before they buy. Write six of them today, so you have three months of emails ready, and save each one as a template.

Find the questions first. Open your sent mail, your call notes, your quotes and any customer interviews, and write down 10 questions buyers asked you before they bought, or the reasons they gave for not buying. Then pick six that cover these:

1. Price: what it will really cost, and what changes the price. Link to your pricing page if you have one.
2. Size: the smallest order or project you take, and why most first orders are small.
3. Timing: how long it takes from yes to delivery, and when to start to hit a date.
4. Sign-off: what the person you talk to needs to show their boss or co-founder. Many B2B purchases need more than one decision maker.
5. Proof: a short story of one customer: their problem, what you did, and the result, which is your value proposition shown in real life. A full case study can come later.
6. Starting small: a sample, a trial, a pilot or a small first order.

Each email follows the same rules: under 150 words, plain text, from you, about one question, with one link at most, and one question at the end that is easy to answer. Leave out company news. In a 2025 Gartner survey of 632 business buyers, 73% said they actively avoid suppliers who send outreach that does not apply to them. An email that answers a question they have is the opposite.

Subject: [the buyer's question, in their words, lower case]Hi [first name],[The question, as buyers ask it.] [The answer in 2 or 3 short sentences, with a real number.][One example: what one customer did, or what most buyers do.][One link, only if it helps: a price list, a photo, a short page.][One easy question: "How many would your first order need?"][Your first name]
[Your business, postal address]
Reply "no" and I'll stop.

Ask ChatGPT or Claude to draft each email from your notes on the question. Then put in the true numbers yourself: your prices, your times, your customer's result. AI makes up numbers if you let it. To use one email for different kinds of buyer, keep the answer and change the example. You can turn each one into a LinkedIn post too, and reuse it wherever your buyers read.

Save each email as a Gmail template. In Gmail on a computer, click Settings, then See all settings, then Advanced. Next to "Templates", click Enable, then Save Changes. Write the email in a new message, then click More options (the three dots), then Templates, then Save draft as template, then Save as new template.

• Tool: a Google Doc for your notes, ChatGPT or Claude to draft, and Gmail templates.
• Time: about 2 hours for six emails.
• You will have: six nurture emails saved as templates, enough for 3 months at one every 14 days.
• It worked if: each one answers a question a real buyer asked, is under 150 words, ends with one question and has no company news.
• Common mistake: a monthly newsletter about your business: "We moved office", "Meet the team". Your buyers want answers to their own questions. Since July 2025, Gmail lists every newsletter-style sender on one page with an unsubscribe button.

4. Send each lead one nurture email every 14 days, by hand

Every day, open your sheet, find each lead whose next email is due today, and send them the nurture email that fits their reason for waiting. Then set their next email for 14 days later.

Pick the email by their reason for waiting:

Then send the rest in any order, one every 14 days. A decide-by date beats the 14 days: 2 weeks before their date, send a short personal email that asks if the date still holds.

To send it: open the template, add one true line about them at the top (AI drafts it from their row), and send it from your normal email address. Do not use a second domain you set up for cold email. These people know you by your main address. If an email is due on a day you will be away, write it the day before and use Schedule send: click the arrow next to Send, then Schedule send, and pick a time. Gmail holds up to 100 scheduled emails.

Keep to the rules. All of these apply to emails to businesses:

• US law: the CAN-SPAM Act has no exception for business email. Every email needs your postal address, a clear way to say no, and a subject that matches the email. Stop within 10 business days when someone says no.
• Gmail's rules: every sender needs SPF or DKIM, two settings that prove an email really comes from your domain. Ask your email host to check one is on. Keep spam reports under 0.3%, and act on any "no" within 48 hours. Since November 2025, Gmail has been rejecting more mail that breaks these rules.
• UK law: you may email people at companies, but you must say who you are and give a way to opt out in every email. Sole traders need to have agreed first.

When to stop: after all six emails with no reply, send one last email that asks if you should stop. If they do not answer, stop. Write to them once more, by hand, 2 weeks before their decide-by date if they gave one.

When to stop doing it by hand: while you have fewer than 100 leads, send every email yourself. That is about 7 emails a day, or 20 minutes. Once you pass 100 leads, or it takes more than an hour a day, put the six emails into one automatic sequence in Kit's free plan, which includes one email sequence. Add only leads who said yes to your emails in step 2, and send it from your own domain. Keep writing by hand to everyone who has replied. A CRM with sequences built in costs much more: Attio's sequences, for example, start on its Pro plan at $79 per user a month, paid yearly. You do not need one at this size.

• Tool: Gmail with templates and Schedule send, your sheet, and ChatGPT or Claude for the personal line. Kit's free plan once you pass 100 leads.
• Time: about 3 minutes an email. With 100 leads, about 20 minutes a day.
• You will have: every lead getting one useful email every 14 days, each one logged in the sheet.
• It worked if: at the end of each day, no email is overdue and every row has a next date.
• Common mistake: sending all your leads the same email on the same day from a newsletter tool, with images and a "no-reply" address. It looks like an advert, nobody can answer it, and the reply is the whole point.

5. Answer every reply the same day and offer a call when a lead is ready

A reply is the most useful thing a nurture email brings, so answer each one the same day. When a reply shows the lead is ready, offer the next step with a date: a 15-minute call, a sample or a quote.

A lead is ready when any of these happens:

• They ask about price, the smallest order, how long it takes, or a sample. These are buying questions.
• They name a date within 30 days.
• Someone else from their company writes to you, or is copied in. That is often the person who decides.
• Their decide-by date arrives.
• Something changes for them that you can see: a new shop, a new product, new funding, a new person in the job you sell to.

Opens do not count. Apple Mail can hide whether someone opened your email, so your open rate can include opens that never happened. Count replies instead: your reply rate is the number to watch, and a click on a link counts only when a reply comes with it.

When a lead is ready, answer their question first, in one or two lines. Then offer the next step with two times or a date. Run the call as a discovery call, send a sales deck if they ask for "more info", and send the proposal the same day. Move them out of the nurture list and into your sales pipeline.

When the lead says someone else decides, ask who, and ask for an introduction. Then send that person the sign-off email from step 3, changed for their job. For bigger buyers with several people involved, account-based marketing and selling to enterprise clients cover how to reach up to 3 people per company.

For other replies:

• "Not yet": thank them, ask when, and write the new date in "decide by".
• A question that is not about buying: answer it fully. It is the best nurture email you will send.
• "No": thank them, move them to "do not email", and never write again.

Thanks, [first name].[The answer to their question, in one or two lines.][The next step]: I can [send a sample today / talk you through it in 15 minutes / send a quote by [day]]. Would [day, time] or [day, time] work?[Your first name]

• Tool: Gmail, your calendar, and your sheet or CRM.
• Time: 5 to 10 minutes a reply.
• You will have: an answer sent to every reply, and a dated next step for every ready lead.
• It worked if: every reply got an answer the same day, and every ready lead has a call, a sample or a quote with a date.
• Common mistake: answering a buying question with the next nurture email. Someone who asks your lead time wants a call, not a tip.

6. Count replies, calls and quotes every Sunday

Every Sunday, write one row in your sheet: how many leads are on the list, how many joined, how many emails you sent, and how many replies, calls, quotes and orders came back. Then use the rules below to change one thing.

Count people by name: who replied, who booked a call, who got a quote, who ordered. Also count each email's sends and replies, so you know which emails work.

Week | On list | New this week | Emails sent | Replies | Calls booked | Quotes sent | Orders | Said no

Then use these rules:

• After each email has gone to 50 leads, if it got no replies, rewrite it or swap it for a new question. Move the email with the most replies earlier in the order.
• If more than 1 in 20 people who get one email say no, that email reads like a sales pitch. Rewrite it to answer the question and nothing more.
• If fewer than 20 new leads joined this week, spend more time on cold email, LinkedIn and calls until you reach 100 messages a day. Nurture cannot turn a small list into many deals.
• After 500 nurture emails, if no calls came from the list, ask 5 leads by phone what they would want to hear about, and write the next emails from their answers.
• Every Sunday, write one new nurture email from the question buyers asked most this week. Each new email gives the list another 2 weeks before anyone gets a repeat.

Once a month, add these numbers to your monthly marketing review, and note which channel each deal first came from, so you can track which channel brought each deal.

• Tool: Google Sheets.
• Time: 30 minutes each Sunday, plus 20 minutes for the new email.
• You will have: one row a week, the replies for each email, and one new nurture email.
• It worked if: you can name every call and quote that came from the list, and which email they answered.
• Common mistake: changing an email after 5 sends because nobody replied. Wait for 50 sends before you judge one email.
