Email - not encrypt this message

When I try to send a test email, everything is OK, but when I send an email to a list of users, e-mail arrives, but Gmail reports: Domain vshosting.cz not encrypt this message.



It is a problem in hosting or setting Mauticu?

Hi,

I have exactly the same problem.
I’ve created a custom Html email and once I send it and land into gmail account it report that Mautic did not encrypt this message.

I am using the pro account and I would like to know why it happens. Do you think is due to the custom email? @MauticEmail @alanhartless any thoughts about the above?
