Can you trust the numbers in Mailtrap?
Mailtrap is one platform for transactional and marketing email, with inbound email and a sandbox for testing email before it goes out. Its own help pages give 3 reasons its numbers can look different from what you expect. The first to rule out: An open rate can look lower than real reading, because Mailtrap's docs say an open is missed when a reader's mail app, browser or settings block its tracking pixel or images.
Is it broken, or just counted differently?
A number can look wrong because the business changed, or because of how Mailtrap counts it. Below is what Mailtrap keeps, where its help pages say the numbers can differ, and how to check them yourself.

What can make Mailtrap's numbers look wrong?
An open rate can look lower than real reading, because Mailtrap's docs say an open is missed when a reader's mail app, browser or settings block its tracking pixel or images.
In Mailtrap's own words:
In each of these cases, an 'open' event won't be recorded even if an email is opened.

In Mailtrap's own words:
Click tracking must be enabled for clicks to be counted.
Email Logs, read 2026-11-12.A delivered email may still have landed in spam, as Mailtrap's docs point out, so a high delivered rate does not mean every email reached the inbox.
In Mailtrap's own words:
Note: this doesn’t exclude a delivery to a spam folder.

How does Mailtrap work with Feder?
Connect Mailtrap to Feder and it joins your Reach apps. Feder only reads. It never changes anything in Mailtrap.
When you connect Mailtrap, Feder checks the connection straight away and shows Connected only when that check passes. If a reading cannot be taken later, Feder shows it as not read, never as zero.

Know the day a number breaks, not the month after.
Some numbers are too quiet to judge daily, such as a form filled in a few times a week. Until there is enough of your own history to judge a change, Feder says it is still learning and scores nothing, rather than guessing.
