Why does it say "No email provider connected"?

What the red banner means and how to turn sending on.


If your dashboard shows a red banner reading "No email provider connected. Campaigns, sequences, and automations won't actually send until you finish setup," here's what's going on — and how to fix it.

What it means

Mailbo doesn't run its own mail servers. To actually deliver email, it connects to a sending provider that you own — for example Amazon SES, Mailgun, SendGrid, Postmark, or any SMTP service. Until you connect one:

  • You can still build everything — contacts, campaigns, sequences, automations.
  • But nothing will actually send. Drafts just sit there.

This is normal for a new account. It's a one-time setup.

How to fix it

  1. Click Connect now in the banner (or go to Settings → SMTP & sending).
  2. Choose your provider from the tiles (Amazon SES is the cheapest for most people).
  3. Enter your sender details and paste the provider's credentials.
  4. Send yourself a test.

The full, step-by-step provider setup lives in the Sending & Deliverability section of this help center — start there for the exact instructions for your provider.

You'll also need to add your business name and address before sending is unlocked. The two banners are separate requirements.

Once a provider is connected and verified, the banner disappears and your sends go out for real.
