How to build an email list from zero

No list yet? No problem. Here are simple, honest ways to get your first hundred subscribers without buying anything.

November 2, 20213 min read

An email list is one of the few marketing channels you truly own. Social media platforms change their rules, and your posts reach fewer people every year. An email lands in someone's inbox because they asked for it.

Every big list started at zero. Here is how to get your first subscribers the right way.

Start with a reason to join

"Join our newsletter" is not a reason. People sign up when they know what they will get and why it is worth their inbox space. Make a clear promise:

  • "One quick recipe every Friday."
  • "Get 10 percent off your first order and early access to new stock."
  • "A monthly roundup of the best jobs in our industry."

Specific beats general every time.

Offer something useful in return

A small free gift, often called a lead magnet, can double your signups. Our list of lead magnet ideas has plenty to choose from. It should be quick to use and closely related to what you sell.

  • A bakery might offer a free printable cake order guide.
  • An accountant might offer a tax deadline checklist.
  • A software company might offer a template or a short guide.

Keep it small. A one page checklist that solves one problem works better than a long ebook nobody finishes.

Put the signup form where people already are

You do not need a fancy setup. Start with the places people already visit:

  • Your website: in the footer, on your blog posts and on a simple dedicated signup page.
  • Your social profiles: add your signup link to your bio and mention it in posts.
  • Your shop or checkout: add a tick box asking customers if they would like updates. Leave it unticked so they choose it.
  • In person: at events, markets or your counter, use a QR code that opens your signup page.

Use a popup, but kindly

Popups work, but they annoy people when they appear instantly. Show them after someone has scrolled down a page or spent some time reading. Make them easy to close on a phone.

Ask your current contacts properly

You may already know hundreds of people: customers, clients, followers. You cannot just add them to your list, but you can invite them. Send a personal message explaining what your emails will offer and share the signup link. Let them choose.

Never buy a list

It is tempting to buy a list and skip the slow part. Do not. Bought lists are full of people who never agreed to hear from you, plus old and fake addresses. You will get spam complaints and bounces, your sender reputation will drop and your email tool may close your account. In many countries it is also against the law.

Confirm new subscribers

Use double opt in, where new subscribers click a link to confirm. It keeps out typos, fake addresses and bots. Your list will grow a little slower, but every person on it is real.

Send a welcome email right away

People are most interested in the minutes after they sign up. Send a welcome email immediately with what you promised, a short hello and what to expect next. Our guide to welcome emails shows exactly what to include.

Keep showing up

Your list grows fastest when your emails are good enough to share. Send consistently, keep your promise and ask happy readers to forward your emails to a friend. A hundred people who love your emails beat ten thousand who ignore them.
