Your Substack Welcome Email Has One Job.
Your welcome email is not a greeting. It is the beginning of a sales pipeline.

How to write a Substack welcome email — short answer: You have four welcome emails: free subscriber, paid subscriber, founding member, and imported list. Each one has a different job and a different audience. The default language Substack gives you for all four is generic and misses the most valuable marketing window you get with any subscriber — the moment right after they clicked subscribe. Below: what each email is for, the mistakes that kill them, the first two ingredients of a free welcome email that works, and the complete system for everything that runs after.

The four Substack welcome emails and what each one is for

The full recipe, the paid and founding member emails, the imported list, and the email system that runs after the welcome
About six months into my Substack journey, I read my welcome email to free subscribers and had a big a-ha moment.
I had written it when I first joined and set up my account, but hadn’t touched it sense. I am a marketer — I was never going to leave the default in place. But reading it again after 6 months, it still was not right.
The problem was the focus. I had packed it with things for people to do: content to read, offers to explore, places to go. None of it had any priority.
The one thing I most wanted new subscribers to do was upgrade to a paying membership, but that primary call to action was buried in the email among four other asks. No wonder it wasn’t getting the traction I expected.
I rewrote it that afternoon. Then I wrote three more.
How many welcome emails does Substack have?
Four. Access them all at Settings → Email → Welcome emails.
Free subscriber: Sent when someone joins your free tier. Your highest open rate. Your highest-stakes first impression.
Paid subscriber: Sent when someone upgrades. Should immediately deliver every benefit they just unlocked, with a direct link to each one.
Founding member: Sent when someone subscribes at the founding tier. They made a significant financial commitment. The email should match that.
Imported list: Sent when you bring a list over from another platform. Many writers skip this one entirely. They shouldn’t.
Why does the welcome email matter?
The moment someone subscribes is the highest-interest window you will have with them. They clicked, they are expecting an email, and they open it. What you do in that email tells them whether they made a good decision.
The Substack default says hello and nothing else. Every element of your welcome email should prove they were right to subscribe.
The most common mistakes in Substack welcome emails
Leaving the default in place. Check your settings right now if you have not changed it.
Writing a biography. New subscribers do not care about your background. They care about what they just signed up for and whether it was worth it.
Too many calls to action. Give someone ten things to click and they click none of them. One email, one goal.
Setting it and forgetting it. Your publication evolves. Review the welcome emails quarterly.
What should you include in a free subscriber welcome email?
The free welcome has one job. Decide what that job is before you write a word, and build every element around it.
The intro. One to two sentences. Confirm they are in the right place. No bio, no credential list. Get to the point immediately.
The value. Give them something right now. A guide, a resource, a link to your best content — something that makes them glad they clicked subscribe before they have read your first issue.
The rest of the recipe — the third ingredient, how to structure the one ask that works, and how to turn that click into the first step of a system that runs itself — is behind the paywall.
