The Problem

Your Emails Are Going to Spam
(And You Don't Even Know It)

78% of email marketers have inbox problems they don't know about. Here's what's hurting your campaigns right now:

Spam Folder Trap

Your carefully crafted emails never reach the inbox. You're losing 30-50% of potential revenue.

Authentication Failures

Broken authentication records make email providers suspicious. They'll flag you as a potential spammer.

Bad List Hygiene

Invalid addresses bounce back. Each bounce hurts your sender reputation.

Reputation Damage

Once your domain is flagged, recovering takes months. Prevention is 10x easier than repair.
