Your first 100 newsletter subscribers, without buying a list

Your first 100 newsletter subscribers will not be strangers. They will be clients, suppliers, people you met at events and people who read your LinkedIn posts. So learning how to get newsletter subscribers from zero is less about growth tricks than about asking the people who already know your name, where they already see it.

This guide, written for small teams starting from nothing, covers those places in the order I would use them, why a bought list is a false shortcut, and how to record where each subscriber came from. For the bigger picture, see my guide to sales funnels and newsletters.

Why buying a list costs more than it saves

A ready-made file of thousands of “opted-in” addresses looks like a shortcut. Four problems make it a bad one.

The consent was given to someone else

In the UK, marketing emails to individuals, sole traders included, need their consent or the soft opt-in (regulation 22 of PECR, explained in the ICO’s email marketing guidance). The ICO’s guidance has long been that consent collected by someone else rarely covers you: it must clearly identify your organisation, and “selected third parties” is not enough. In France, the CNIL expects the full list of partners to be available, on the form or through a link, when people consent. Companies fall outside PECR’s consent rule, but the next three problems still apply.

Your email tool forbids it

Mailchimp’s Acceptable Use Policy bans purchased, rented and third-party lists, partner lists and addresses gathered from public sources. Check your own tool’s terms: if it suspends your account over a bought list, your genuine subscribers stop hearing from you too.

Spam traps

Some addresses exist only to catch senders who never asked for permission: addresses that never signed up for anything, or old ones a provider closed and reused. Bought lists are where they end up, and hitting them can put your domain on a blocklist. A verifier such as Reoon, which I use every day, flags some of them, but cleaning a list does not add the consent it lacks.

Complaints

Strangers click “Report spam”. Google’s email sender guidelines ask senders to keep their spam rate below 0.1% and never reach 0.3%: three complaints on a mailing of 1,000. Past that point, your emails are more likely to land in spam, even for the clients who wanted them.

How to get newsletter subscribers from people who already know you

Start with a list on paper, not in your email tool: current and past clients, suppliers, partners, people you met at events or who email you questions, your LinkedIn connections. That number is your honest starting point.

Then invite them; do not import them. A short personal message with a link to your sign-up page lets each person subscribe and confirm with one click, and your tool keeps the consent record.

Who can receive that invitation by email depends on who they are:

• People at companies: PECR’s consent rule does not cover companies, and in France the CNIL accepts emails to professionals about their line of work if they were told and can object easily. A one-to-one invitation is fine.
• Individual clients, and in the UK people who asked you for a quote: the soft opt-in covers details you collected during a sale or negotiations for one, for your own similar services, but only if you offered a way to refuse then and in every message since. In France, the equivalent exception only covers people who are already your clients.
• Everyone else: ask in person, on a call or at the end of a project. In the UK, an email asking whether people want your marketing is itself marketing: the ICO fined Flybe and Honda for exactly that in 2017.

Finally, add one line to your email signature: what the newsletter is, how often it arrives, and the link, such as “One practical tip on [your subject] every month: subscribe here.” Every email you send becomes a quiet invitation.

Make your website ask in four places

1. The end of each article: whoever has just finished an article on your subject is the most likely to want the next one. One field, one button, one sentence on what they will receive.
2. A dedicated sign-up page, such as /newsletter, saying what the newsletter covers, how often it arrives and that unsubscribing takes one click, with a past issue to read. It is the link you share everywhere else.
3. The footer: a short form on every page catches visitors who never open an article.
4. A pop-up, sparingly: after a visitor has scrolled most of a page or is about to leave, and only once. Never a screen that hides the content on a phone; Google’s search guidance treats intrusive interstitials as a poor page experience.

A lead magnet, such as a checklist or a template that solves one small problem next to what you sell, gives people a reason to sign up today. Deliver it to everyone who asks and offer the newsletter as a separate, unticked box; my 12 lead magnet ideas show what works for service businesses.

If adding a form to your articles means fighting your theme, fix that first, on your own or with a web designer: a website that loses the visitors you send it wastes every other effort in this guide.

LinkedIn: your posts and the Featured section

If your clients are businesses, many already read you on LinkedIn. Two habits turn them into subscribers. First, turn each issue into a post: one idea, written to stand on its own, ending with a line saying the full version goes out by email, with the link. Second, use the Featured section of your profile, near the top under About: it can hold a link to your sign-up page, with a title that says what readers get.

Do not send the same invitation to every connection by private message: it reads as a mass mailing because it is one. LinkedIn’s own newsletter format is a different choice, which I compare in LinkedIn newsletter, email newsletter or Substack.

Borrow other people’s audiences

Next come audiences that belong to someone else, with their agreement:

• Talks, workshops and trade fairs: a QR code to your sign-up page on your last slide or your stand, with one line on what people get. A business card handed to you is not a sign-up: ask, or let them scan the code.
• Partners and newsletter swaps: a business that serves the same clients without competing, as an accountant and an employment lawyer do, recommends your newsletter in one issue and you recommend theirs. You swap mentions, never addresses.
• Guest articles and podcasts: write for a trade publication or a partner’s blog, or appear on a podcast your clients follow, with your bio linking to your sign-up page.

Referral programmes: when readers bring readers

A referral programme gives every subscriber a personal link; when friends sign up through it, the subscriber earns a reward, such as a template or a mention in an issue. At the time of writing (October 2026), beehiiv includes one from its paid Scale plan (not the free Launch plan), and Kit offers a newsletter referral system, run with SparkLoop, on its Pro plan, according to Kit’s plan comparison. For other tools, check their integrations and my comparison of newsletter tools.

Two rules keep it clean. Friends sign up through the link themselves: never a form where subscribers type a friend’s address for your tool to email. And keep rewards modest, or you attract people who want the reward rather than your emails. A referral programme multiplies the audience you already have, so wait until readers clearly like what they receive.

Tag every sign-up with its source

In three months you will want to know which channels brought readers who open, reply and stay. Set it up from the first subscriber:

• One form per place (end of articles, footer, sign-up page, pop-up), each adding its own tag. Kit and Mailchimp call them tags, MailerLite groups, Brevo lists.
• One link per channel outside your website (signature, LinkedIn, a partner’s issue, podcast notes), with UTM parameters so your analytics show where sign-up page visitors came from.
• A record of consent: the date, the form and the wording each subscriber saw, including old versions of your forms.

Every quarter, keep the two or three channels that bring readers who stay and drop the rest. If I had to insist on one thing about marketing, it would be this: it is easy to fall for the shiny new channel, and far more useful to focus on the ones you already use.

What to expect from your first 100

No reliable benchmark says how long 100 subscribers take: it depends on how many people know you and how many visit your website. Use your own numbers, with this table as a guide:

Expect a first wave from the people you invite, then a slower, steadier flow from your website and partners; that is normal. What makes the second hundred easier is what the first hundred receive: a welcome sequence that introduces you, and issues that arrive when you said they would.

Your first-100 checklist

1. Set up a sign-up page, double opt-in and a welcome email.
2. List the people who know your work and invite them one by one, by email where the rules allow and in person otherwise.
3. Add the newsletter line to your signature, and tagged forms at the end of articles and in the footer.
4. Put the sign-up page in your LinkedIn Featured section and post from each issue.
5. Plan one talk, swap or guest appearance a month.
6. Send every issue on schedule from the first subscriber, and compare sources after three months.
7. Add a referral programme once your issues get replies.
