Marketers and sales reps are in a constant struggle to maximize email deliverability. The latest estimates place the average deliverability rate at just 81%. That essentially means 19% of your emails disappear in thin air. 

Achieving high deliverability rates involves multiple factors. You have to hit the right spot with your volume per mailbox, correctly configure domains and mailboxes, and navigate the technical settings of your email infrastructure.

But before you throw in the towel, read our guide on email deliverability testing to tackle these challenges head-on.

How to test email deliverability (using Folderly)

Folderly is designed by Belkins as a complex, full-scale platform to test email deliverability and beyond with a suite of tools, like Folderly Core, Folderly Inbox Insights, free SPF Generator, and Spam Words Checker.

How to interpret your test results

So, you’ve completed the first round of your email deliverability testing process. When you open the test results, you can see a bunch of numbers splashed across your screen.

You’re wondering: What do these numbers say about your email campaigns? Does this data indicate something good or flag something bad?

Here’s a breakdown of the analytics you’ll find on your Folderly test dashboard:

  • Sender score: indicates the overall health score of your mailbox
  • Domain and mailbox analysis: indicates the health of your email infrastructure (SPF, DMARC, DKIM, and BIMI)
