How to build an email list for free

You know you should have an email list, so you added a signup box, and almost nobody joins. A form alone cannot fix that: about 3 in 100 people who see a signup form fill it in, so a site with 300 visits a month gets about 9 emails. Here is how to build an email list for free when you have almost no traffic: one free thing worth joining for, a free signup page, and people you ask one at a time, every day.

Do these three things

About 5 hours a day, every day, for 4 weeks. That is 2,800 personal asks. Judge each source after 1,000 asks or answers, by how many people joined per 100.

Show the three actions in fullHide the full list

1. 1Today: pick one free thing your buyers want, such as a checklist, a template or a free tool. Put up a free signup page for it that sends email from your own domain.
2. 2Every day: ask 100 people personally if they want it, give 20 answers in 5 places where your buyers ask for help, and post twice on each of your 2 channels with the link. Add only people who said yes or signed up themselves. AI drafts; you add one true line.
3. 3Every Sunday: send your list one short, useful email with one question. Count new subscribers by where they came from, and give next week's hours to the best source.

1. Pick one free thing people get when they join your email list

Give people one specific, free thing they get the moment they join, made for one kind of buyer and one problem. "Join our newsletter" promises nothing, so almost nobody joins.

This free thing is called a lead magnet. Pick one problem from your ideal customer profile that your buyers try to fix on their own before they buy. Then make one thing they can use within 10 minutes of joining:

• A checklist or a template: the steps you follow, or the sheet you use, for that problem.
• A price or buying guide: what things cost, what to ask a supplier, what to check before buying.
• A free tool result: your product does one small job for free. If you run a SaaS, build a free tool and email people their result.
• A sample or a first-order offer, for a store. See the D2C block below.

Use the words your buyers use. Copy them from your customer interviews, sales calls and the questions people ask in online communities. A one-page checklist that solves one real problem beats a 40-page ebook that nobody opens.

Let AI draft it. Give ChatGPT or Claude the problem, your notes and 10 buyer questions, and ask for a one-page draft. Then add what only you know: your numbers, your mistakes, your real steps. Check every fact. Then write one line that says what it is, who it is for and when they get it. That line goes on your signup page, in your messages and in your posts. It works like a small value proposition.

[The free thing] for [who it is for] who [the problem, in their words]. Free, in your inbox in 2 minutes.

Before you build anything else, send the line to 5 people who fit your buyer and ask: "Would this be useful to you?"

If you run a D2C store: a first-order discount works, but it brings people who only want the discount. Offer something useful too, such as a care guide or a "which one is right for me" chart, and keep any discount small. Write a popup that isn't just a discount goes further.

If you run a B2B business: a price guide or a buying checklist works best, because your buyers are comparing suppliers. Keep it to one page they can forward to their boss.

If you run an agency: give away the checklist or template you use with clients, such as an audit sheet or a 30-day post plan. It shows how you work.

• Tool: Google Docs, and ChatGPT or Claude to draft. Free.
• Time: about 3 hours.
• You will have: one free thing people can use in 10 minutes, and a one-line offer.
• It worked if: at least 3 of the 5 people you asked say they want it.
• Common mistake: "Subscribe for updates" with no promise, or a long ebook that takes a week to write and nobody finishes.

2. Set up a free email list and a signup page

Open a free Kit account, connect your own domain so your emails reach the inbox, and make one signup page that sends your free thing to everyone who joins. You do not need a website: the page has its own link.

Use Kit's free Newsletter plan. It covers up to 10,000 subscribers, with unlimited signup forms, landing pages and emails, and one automation, which you will use for the welcome email. Other free plans are much smaller today: Mailchimp's free plan stops at 250 contacts and 500 emails a month, and MailerLite's at 250 subscribers. At 100 asks a day, you could pass 250 in your first weeks.

Set it up in this order:

1. Send from your own domain. Use an address like you@yourcompany.com, not @gmail.com. Email tools cannot send as a gmail.com address, because Gmail rejects mail that says it is from gmail.com but was sent from somewhere else. If you have no domain, buy one: it is the only cost in this guide. In Kit, click your account name, then Settings, then Email. Under "Verified Sending Domains", click "Set up your Verified Sending Domain", enter your domain and click Next. Choose "Set this up for me", or copy the records into your domain settings and click "Validate". This sets up SPF, DKIM and DMARC, settings that tell inboxes your emails really come from you.
2. Make the signup page. Go to "Audience growth", then "Landing Pages & Forms", click "+ New" and choose "Landing Page". Pick a plain template. Write the headline from your one-line offer, ask for the email address only, and add a line on what else you will send. Copy the link from Share, "Copy your Landing Page's URL". AI can draft the page and the welcome email from the templates below; you check every line.
3. Write the welcome email and send it with your free plan's one automation, to everyone who joins through the page. It gives them the free thing and asks one question they can reply to.
4. If you have a website, go back to "Landing Pages & Forms", choose "Form", and put it on your homepage, at the end of every article and in the footer. Tag every link to your signup page with UTM parameters, one per place, so you know where people came from. If you have no site yet, share the landing page link, or make a one-page site later.

Do not import your phone contacts, LinkedIn connections or old customers who never agreed to hear from you. Kit's rule is that each person must have agreed to receive your marketing emails, and "simply knowing them personally—or having them in your address book—isn't enough". The law says the same in many places. In the UK, you may not send marketing emails to individuals without their consent, unless they bought something similar from you and could say no.

[The free thing] for [who it is for].[One line: the problem it fixes, in their words.]Free, in your inbox in 2 minutes. After that, one short email every Sunday about [the problem]. Leave any time.Email: [field][Send it to me]

Subject: Here is your [free thing]Hi,Here it is: [link to the free thing].Start with [the one part to use first]. It takes about 10 minutes.One question: what is the hardest part of [the problem] for you right now? Just reply. I read every answer.[Your name]
[Your company, postal address]
[Leave the list]

If you run a D2C store on Shopify: use Shopify Forms, a free Shopify app, for a popup and a form on your store, and send with Shopify Messaging. Stores on the Basic plan and up get 10,000 free emails a month, then $1 per 1,000. Show the popup after a few seconds of scrolling, not the moment the page opens. When you have more orders, set up Klaviyo flows.

• Tool: Kit's free Newsletter plan, or Shopify Forms and Shopify Messaging for a store. Your own domain.
• Time: about 2 hours.
• You will have: a live signup page with its own link, a form on your site if you have one, and a welcome email that sends the free thing.
• It worked if: you sign up with a Gmail address and an Outlook address, and both get the welcome email in the inbox, not in spam, within 5 minutes. If it lands in spam, check your email deliverability settings before you send anyone the link.
• Common mistake: sending from a free @gmail.com address, or a form that asks for name, company, phone and job title. The other mistake is adding people who never said yes.

3. Ask 100 people a day to join your email list

Send 100 personal messages every day that offer your free thing and ask if the person wants it. Add people to your list only when they say yes, or when they sign up through your page themselves.

This is where your first subscribers come from. With a few hundred visits a month, your form brings a handful of people. Asking people one at a time brings far more, and the people who join know your name. A founder on Hacker News in April 2026 put it simply: to grow an email list faster, "talk individually".

Message in this order: people you know, then people you have worked with or sold to before, then new people who fit your buyer. Start with warm outreach: friends, past colleagues, people in your groups. At 100 a day, you need 100 new names every day on your lead list: 2,800 over 4 weeks. A lead list is people you may contact; your email list is only the people who said yes.

Let AI draft. Paste 10 names at a time into ChatGPT or Claude, each with one thing you know about the person, plus the template below. Read each draft, make the first line true, and send. That is about a minute a message. Send the link straight away to people you know. For strangers, ask first and send the link when they say yes: the first message stays short, and fewer land in spam. Follow up twice with anyone who has not replied, 3 days apart.

Keep to each channel's rules, and spread the 100 instead of cutting it:

• Email: set up SPF and DKIM on the domain you send from, and use a second, warmed-up domain if you email more than about 50 strangers a day. In the US, every message to a stranger needs your postal address and a clear way to say no.
• LinkedIn: LinkedIn limits how many invitations you can send each week, so message people you are already connected to and fix your profile first.
• Direct messages on the social apps your buyers use make up the rest.

Subject: [the problem, in 3 to 5 words]Hi [first name],[One true line about them: something they made, wrote or said.]I made [the free thing] for [kind of person] who [the problem]. It takes about 10 minutes to use.Want it? Say yes and I'll send it over.[Your name]
[Your company, postal address]
Not for you? Reply "no" and I won't write again.

If you run a B2B business: do not add your cold lead list to your email list. Send each buyer the personal ask, and add them only when they say yes. Later, nurture those leads by email.

If you run a D2C store: most shoppers will not answer a stranger's message. Ask the people you know, small creators who fit your buyer, and everyone who messages or comments on your posts. Put the link on the order confirmation page and in every parcel too.

• Tool: Gmail, LinkedIn or direct messages, ChatGPT or Claude to draft, and a Google Sheet with one row per person and a "Said yes" column.
• Time: about 2 hours a day for asks and follow-ups, and 45 minutes to find 100 new names.
• You will have: 2,800 personal asks sent in 4 weeks, and a sheet showing who said yes.
• It worked if: at least 5 people join for every 100 asks. Below 2 after 300 asks, change the first line or the free thing, then send the next 100.
• Common mistake: adding everyone you messaged to your list. People who did not say yes mark your emails as spam.

4. Put your signup link in 20 answers and 2 posts a day

Give 20 useful answers a day in 5 places where your buyers ask for help, and post twice a day on each of your 2 social channels. Mention your free thing where it answers the question, and put your signup link everywhere people already see you.

Answers. Good places are a subreddit, a Facebook group, a Slack or Discord group and a forum about your kind of problem. Read each place's rules on self-promotion first. Spreading 20 answers over 5 places keeps you inside each one's rules. Answer the question fully, as if your free thing did not exist. Where someone asks for a template or a checklist, or the place allows links, say you made one, say it is yours, and share the link. AI can find threads and list the points to cover; write each answer yourself, because communities remove replies that read as pasted from AI.

Posts. Pick two channels where your buyers are: LinkedIn for most business buyers, Instagram for most shoppers, X for people who build software. Post twice a day on each, from a content calendar you fill every Sunday. Each post gives one useful part of your free thing, such as one tip, one step or one example, and twice a week a post ends with "Want the full [free thing]? The link is in my profile" or "comment and I'll send it". Let AI draft 10 posts at a time from your notes, keep the true ones and rewrite them in your voice. Grow on LinkedIn as a founder the same way, and add a 9:16 short video when you can.

The link everywhere. Today, put your signup link in the places people already see you: your social bios, your email signature, your site footer, the end of every article, your order or signup confirmation page, and any webinar or podcast you join. Each one takes a minute and keeps working. If you publish one article a day, end each one with your signup form and a line about the free thing.

[The problem, in one line, in your buyers' words.]Here is what I do about it: [one tip or step from your free thing].I put the whole thing in [the free thing]: [what is in it, in one line].Want it? [Comment "send" and I'll send it / The link is in my profile.]

• Tool: the search box on each community, LinkedIn, Instagram or X, and ChatGPT or Claude to draft posts. All free.
• Time: about 1 hour a day for answers (3 minutes each) and 40 minutes for posts.
• You will have: 560 answers and 112 posts in 4 weeks, and your link in every place people already see you.
• It worked if: by day 14, at least 1 in 5 new subscribers came from answers, posts or your bio link.
• Common mistake: a link in every answer. The posts get removed, and people remember you as the one who spams.

5. Write to every new subscriber within 24 hours and email the list every Sunday

Write a short personal note to everyone who joins, within 24 hours, from your own email. Every Sunday, send the whole list one short, useful email with one question they can reply to.

People who joined and then hear nothing for weeks forget why they joined. When an email finally arrives, some mark it as spam. Gmail asks every sender to keep the share of emails marked as spam under 0.3%, the spam complaint rate, and a cold list pushes you toward it. A note within a day stops that, and the replies tell you what your buyers need, which is free feedback from your first users.

Every day: open your list in Kit and write to each person who joined in the last 24 hours, from your own email. Thank them, ask if the free thing helped, and ask about their problem. If they answered the welcome email's question, reply to what they said. When someone clearly has the problem now, offer a 15-minute call. Mark each person in your sheet: "has the problem now" or "curious". AI can draft each note from what the person wrote, in about a minute; you make it true and send it yourself.

Every Sunday: send the whole list one short email from Kit: one useful thing (a tip, a short case study or what you learned this week), one link at most, and one question. Keep it under 150 words. Check that it shows your postal address and a link to leave the list. In the US, you must remove anyone who asks within 10 business days. Grow a newsletter from scratch goes further once your list is growing.

Subject: Did the [free thing] help?Hi [first name],Thanks for joining. I'm [your name], and I made [the free thing].Did it help with [the problem]? What are you working on right now?Just reply, I read every answer.[Your name]

Subject: [one useful thing, in 5 words or fewer]Hi [first name],[One tip, step or lesson about the problem, in 3 to 5 short lines.][One link, only if it helps: a page, a video or a reply thread.]One question: [a question about their problem]? Just reply. I read every answer.[Your name]
[Your company, postal address]
[Leave the list]

If you run a SaaS: everyone who signs up for your product gets your onboarding emails instead. Keep this list for people who have not signed up yet, and give each Sunday email one line on how your product fixes the problem.

• Tool: your own email for personal notes, Kit for the Sunday email (Shopify Messaging for a store), and your Google Sheet.
• Time: about 30 minutes a day, and 30 minutes every Sunday.
• You will have: a personal note to everyone who joined, 4 Sunday emails, and a list marked "has the problem now" or "curious".
• It worked if: at least 1 in 5 people reply to your personal note, and each Sunday email loses fewer than 1 in 100 people to unsubscribes.
• Common mistake: saying nothing for a month, then sending a sale email. The other mistake is a long newsletter; one short email with one question gets more replies.

6. Count new subscribers by source every Sunday and move your hours

Every Sunday, count new subscribers from each source, divide by the work that source took, and give next week's hours to the source that brought the most subscribers who reply.

Your total number of subscribers tells you little. What you need is which source brings people who join and reply, for the hours it takes. Your UTM tags, the "Said yes" column in your sheet and your form's visits show where most people came from. Ask "Where did you hear about me?" in your personal note too: that is self-reported attribution, and it catches what links miss.

Fill in one row per source each Sunday: what you did (asks sent, answers given, posts made, visits to the page), how many joined, joined per 100, and how many replied to your note. Paste the week's numbers into ChatGPT or Claude to work out the "per 100" column, then check the sums. Then use this rule:

• After 1,000 asks or answers, a source bringing fewer than 2 subscribers per 100: change one thing (the first line, the free thing or the place) and give it 500 more. If it is still under 2, stop it and move its hours.
• The source with the most subscribers who replied gets the extra hours next week.
• After 4 weeks and 2,800 asks, look at who replied "has the problem now" and how many became customers. Ask the ones who did not buy what stopped them. That answer is your next change, and why no one is buying shows how to find it.

Expect slow, small numbers at first. The April 2026 Hacker News founder set a goal of 6 months to reach 1,000 subscribers, posting and talking to people every day. Kit's free plan carries you to 10,000, so you will not need to pay for a long time. Once you have customers, add a line asking them to refer a friend, and swap a mention with a brand that sells to the same buyers. Before you launch something new, email this list first, the same way you would a waitlist.

Week: [date]Personal asks: [asks sent] sent, [number] joined, [joined per 100] per 100, [number] replied
Answers: [answers given] given, [number] joined, [joined per 100] per 100, [number] replied
Posts: [posts made] made, [number] joined, [joined per 100] per 100, [number] replied
Form on site: [visits] visits, [number] joined, [joined per 100] per 100, [number] repliedNext week, more hours to: [source]

• Tool: your Google Sheet and Kit's subscriber list.
• Time: 30 minutes every Sunday.
• You will have: one row per source each week, and next week's hours decided by number.
• It worked if: you can name your best source and the number that makes it best.
• Common mistake: counting only the total. A source with many subscribers who never reply is worth less than one with fewer people who do.
