Supabase (SMTP)

Supabase Auth sends confirmation, magic-link, and password-reset emails through its built-in SMTP server, which is rate-limited and only meant for testing. Wire it up to MailBlastr's SMTP relay so auth emails are delivered reliably and tracked in your dashboard.

Prerequisites

• A MailBlastr API key.
• A verified domain to send from.

1. Get your SMTP credentials

You'll configure Supabase with the following MailBlastr credentials:

2. Enable custom SMTP in Supabase

After logging into Supabase, enable the SMTP integration:

1. 1
   Open your project

   Go to your Supabase project.

2. 2
   Authentication

   Click Authentication in the left sidebar.

3. 3
   Email notifications

   Click Email under the Notifications section.

4. 4
   SMTP Settings

   Click SMTP Settings and enable custom SMTP.

5. 5
   Sender details

   Add your Sender email and name (both required). The Sender email must be on a verified domain, e.g. support@yourdomain.com and Acme Support.

6. 6
   Paste credentials

   Enter the MailBlastr host, port, username (mailblastr), and password (your API key) from the section above.

Click Save. From now on, all Supabase Auth emails are sent through MailBlastr.
