Get started on Postra

New accounts start with a hosted Postra mailbox. Custom domains come after you link single sign-on. The Getting started overlay walks you through it the first time you open mail.

1. Create your Postra mailbox

This is your primary address and how you sign in.

1. Open mail. If you have no Postra mailbox yet, Getting started appears
2. Pick the name before @ (or keep the one from signup if it is already locked)
3. Set a mailbox password, at least 8 characters
4. Choose Create mailbox

Availability is checked as you type. If the address is taken, pick another.

2. Link single sign-on

SSO is optional for day-to-day mail, but required before you can add a custom domain.

1. In Getting started, choose Link SSO, or open Profile → Single sign-on
2. Link a provider (for example GitHub)
3. Come back to Postra when the provider confirms

Your mailbox password still works for sign-in after you link a provider.

3. Add your domain

1. Choose Add a domain (Getting started or Profile → Domains)
2. Enter the domain you own
3. Add the DNS records we show, especially MX
4. Wait for verification, then create the first mailbox on that domain

DNS details and what each record does: Add a domain and set DNS.

If something blocks you

• “Link a single sign-on provider… before adding a domain” means step 2 is still open
• No Getting started overlay: open Profile → Domains or Profile → Single sign-on directly
• Need a hand: Support Center from the profile menu, or chat from this Help site
