Email deliverability refers to how successfully your emails reach recipients’ inboxes; not just whether they’re sent, but whether they land in the primary inbox instead of spam or being rejected altogether.
Good deliverability means your messages are trusted by mail providers like Gmail, Outlook, and Yahoo. It's a result of strong sender reputation, authentication, and consistent sending practices.
Even the best marketing or transactional emails fail if they never reach the inbox. Low deliverability can lead to lost revenue, missed customer communication, and damaged brand credibility.
The main factors affecting deliverability include:
High deliverability isn’t just technical, it reflects an organization’s overall email hygiene and credibility.
Improving deliverability starts with implementing SPF, DKIM, and DMARC to prove that your emails come from verified, authorized sources. It also involves:
Regularly reviewing your domain’s performance helps prevent issues before they impact your entire mail stream.
Authentication visibility is key to deliverability, and that’s where DMARCeye helps. By analyzing your DMARC and DKIM reports, DMARCeye shows which servers are sending mail on your behalf and whether those messages are being properly authenticated. This helps identify configuration errors, unauthorized sources, and policy gaps that could harm deliverability.
With these insights, you can enforce stronger DMARC policies confidently, improving both security and inbox placement.
