It's not about content, more about email servers not having the proper SPF, reverse DNS, or DKIM configurations. Sometimes only 1 is missing from a setup, which is enough for CF to bounce the emails.
@smitmartijn set up forwardemail.net - really good service, thanks for the advice. The free plan even lets you send email as another email address using gmail's smtp servers (did not know this was possible) which is amazing. Switched over my support email to this service and it's working great

Interesting, now you’ve got me paranoid that I am in fact missing some emails. I’ll check out forwardemail later - they seem to have a free plan too
