The Problem

Your email goes to Promotions because…

Gmail's classifier looks at hundreds of signals. Most marketers have no idea which ones they're triggering.

  • Image-heavy layouts trigger Gmail's Promotions classifier
  • Marketing language like "free," "win," "limited time"
  • Tracking pixels and wrapped links signal bulk mail
  • Missing or broken SPF, DKIM, or DMARC records
  • Buttons and CTAs that look like ads
  • Sending from a low-reputation IP pool

And then gives you exact rewrites to fix each issue.

Three tools, one problem solved

Everything you need to reach Primary

No jargon. No dashboards you don't understand. Just clear answers and specific fixes.
