Content-Type' found without required MIME headers

[Jason Thompson]

Hi, for some reason when i do a mail test on mail-tester its coming back saying no MIME headers found.

This is the error message


Then when i view source code of my clients sending emails using mailwizz it shows the MIME header in their sending, but for some reason not mine.

For example on my clients sending it shows like this: MIME-Version: 1.0



But on my sending it shows like this:



So my question is why is MIME header showing on my clients sending and not mine? I'm pretty sure its affecting my email deliverability.

Hello,
Mailwizz is adding that header for sure in all the possible cases. What is happening after the email is handled to the delivery server is out of Mailwizz control. The delivery server provider settings is the place to look.

Can I change it with my own customized header ?
Cause I saw some people change the header for better deliverability

Can I change it with my own customized header ?

Yes, there are hooks in place which allow you to modify the default behavior.
What exactly do you try to do?

@Mastikalinja - Changing headers is really something that you need to understand why do it first, it has serious implications.
More than sure your delivery is not affected by these headers.
