DNS and deliverability checker

Catch SPF, DKIM and DMARC problems before they cost you a domain.

What it does

The built-in checker looks up your sending domain's SPF (exactly one v=spf1 record), DKIM and DMARC records and explains what to fix. The template editor also has a spam-word check and preview.

How it works

Open Settings, enter your domain (and DKIM selector if you know it) and run the DNS check.
Read the pass/fail for SPF, DKIM and DMARC with hints.
Fix records at your DNS host and check again.
