What hurts inbox placement

The biggest drivers are sending to invalid or unengaged addresses, missing or misconfigured SPF, DKIM and DMARC, and a damaged sender reputation from past bounces and complaints.

What improves it

Clean lists, correct authentication, consistent sending, and engaged recipients. Verification addresses the list-quality and bounce side of that equation directly.

Frequently asked questions

What is email deliverability?

It is whether your messages arrive in the inbox rather than bouncing or landing in spam. It depends on list quality, sender reputation and authentication.

Does authentication affect deliverability?

Yes. Correct SPF, DKIM and DMARC let mailbox providers confirm your mail is legitimate, which improves inbox placement.
