Why the launch email matters
Your list is the most reliable launch channel you have: these people asked to hear from you. A short, personal email on launch day often brings more engaged users than any platform. Send it after your listing is live and checked, in the morning of your readers' main time zone.
Writing it
Keep it short and plain: a subject line that says what happened, a line on why you built it, what the product does, a launch offer if you have one, and one link. Sign it with your name and invite replies. Follow up a week later with what you changed after launch; our guide to the weeks after launch has a full email sequence.
Questions
When should I send a launch email?
On launch day, once your listing is live, in the morning of your readers' main time zone.
Should a launch email have images?
Plain text from a person often gets more replies. One screenshot is fine; a designed newsletter can feel like marketing.
What should the subject line say?
What happened, plainly: "Acme is live" works better than a clever line.
Is anything I type sent anywhere?
No. The email is written in your browser and nothing is uploaded.
