How to connect SendGrid, Mailgun or Brevo

SendGrid, Mailgun and Brevo all send through an email API. The exact provider dashboard looks different, but the WordPress setup is similar: verify who is allowed to send, create an API key, select the provider in Titanium and test the connection.

General API-provider setup

  1. Create an account with SendGrid, Mailgun or Brevo and complete any required account verification.
  2. Verify a sender address or sending domain in the provider dashboard.
  3. Create an API key with permission to send email.
  4. Select the matching provider in Titanium Mail SMTP and paste the API key.
  5. For Mailgun, also enter the sending domain and choose the correct US or EU region.
  6. Save the settings, then send a real Test Email through the configured connection.

Start with one reliable connection, then add complexity only when the site needs it.

The Free version covers popular providers, a Primary Connection, one Additional Connection, visual AND/OR Smart Routing, real test emails, simple failure alerts and supported WP Mail SMTP primary migration. Pro adds unlimited connections, backup delivery, automatic retry, full email logs, source detection, resend tools, protected alerts and visual scheduled reports.
