Unable to send plain-text emails and sender name missing

Sven Amann_76110

I just discovered that Pipedrive is not sending plain-text emails anymore, even if there's no formatting in the mail. This was different only a short while ago. Is there any way to switch this back? We don't ever send HTML emails to individuals.

Any help highly appreciated!

Update: Support told me this is a bug and escalated to engineering.
