What's on your launch checklist?

Hello everyone!

First time posting in here. Last year, after several years of working in the software industry I decided it was more than enough for me. I've been working on a few ideas this year and am finally coming close to launching one.

I always try to keep checklists for things that require more than a few steps so I don't feel like I am missing something and was wondering what's on everybody's checklist before launching a product (sorted by importance), e.g.

• register a domain
• setup emails
• create a landing page
• add a chat support client
• etc.
