I ran into the same issue before. When I verified my domain using DKIM then the email displayed correctly in Gmail because Gmail wouldn’t strip away styles or images. Another plus is that the email won’t go to SPAM.
It doesn’t work. GrapeJS inner Mautic 4 move inline css to and move this to end of .
Unfortunelly, Mautic forces use GrapesJS if you want to use “send e-mail” from contact card (it functionally doesn’t work if GrapesJS is off). User is in an impasse.
Unfortunately even the MJML editor has problems. In the case of sending an e-mail from a template on the contact card, all columns are in the full width of the e-mail.
And I don’t know does the dynamic elements of the e-mail work on the MJML editor? I don’t think so.
