How to tease each newsletter issue on social media

Teasing each newsletter means posting a short preview of the next issue on your social accounts, usually the day before you send it, with a link to subscribe. It works when you already have followers who like your posts but have not given you their email. The teaser shows what a subscriber will get this week, which is more concrete than a generic "join my newsletter".

How to do it

1. Write the teaser after the issue is drafted, so you promise only what is in it. Pull the two or three most useful items.
2. Lead with the benefit, not the topic. "How to handle a client who pays late" tells a reader more than "this week: invoicing".
3. Post it the day before the send, or the morning of. Keep it to a few lines.
4. Add your real subscriber count if it helps. "Tomorrow I'm sending this to 4,800 subscribers" is social proof only if the number is true. If the count is small, skip it and talk about the issue.
5. End with one clear action and one link to the signup page. Give each teaser its own tracked link (a UTM tag on the URL) so you can see which topics bring signups.
6. Repeat every issue, and keep a note of which teaser styles bring signups and which do not. Change one thing at a time: the headline, the length or the posting time.
7. Link the archive. When someone clicks, the signup page should show a recent issue so they can see the quality.

What it looks like in practice

Say you write a weekly newsletter for freelance designers. On Thursday evening you post: "Tomorrow's issue: how to word a late-payment email; the contract clause worth adding; a template you can copy. Free, one email a week. Sign up here:" followed by the link. On Friday you send the issue and, in a second post, share one useful line from it with the same link. This is a hypothetical walkthrough with no results attached.

Examples

Buttondown, an email platform, built a related feature for paid newsletters in June 2022. When you send to a group of subscribers, you can also send a teaser to non-paying ones. By default it contains "the first three paragraphs of your newsletter" and then prompts readers to subscribe for the rest (Buttondown). That is a teaser by email, but the idea is the same: show a real piece of the issue to people who have not paid or signed up.

You can also pair this with a newsletter referral program, so that existing subscribers share the issue and not only you.

When it backfires

• Inflated numbers. Round up a subscriber count and you are making a false claim to the people you are trying to win over. Use the real figure from your email platform.
• Spoilers. If the teaser gives away the whole point, readers have no reason to subscribe. Give the question and a taste of the answer.
• Promising more than the issue delivers. One disappointing issue after a big teaser leads to unsubscribes.
• Posting only to ask. If every post is a plug, followers tune out. Share useful posts between teasers.
• No public benchmark. There is no reliable figure for how many followers a teaser converts, so measure your own with tracked links.

Questions people ask

What is a newsletter teaser? A short post or email that previews what is in the next issue to get people to subscribe or read.

When should I post a newsletter teaser? The day before the send or the morning of it works for most weekly writers. Test a couple of times and compare signups.
