Frequently Asked Questions

Why am I landing in spam?

Common causes include missing SPF/DKIM/DMARC authentication, blacklist issues, poor sender reputation, content triggers, or infrastructure problems. Our comprehensive test identifies specific issues affecting your deliverability.

How fast do fixes help?

DNS changes take 1-48 hours to propagate globally. Authentication improvements show immediate results once propagated. Reputation improvements can take days to weeks depending on sending volume and consistency.

What's a good deliverability score?

Scores above 80 are generally good, above 90 are excellent. Focus on fixing high-impact issues first: authentication (SPF/DKIM/DMARC), then blacklists, then infrastructure optimizations.
