Force Plain Text

Hey all,

Is there currently a functionality to force mautic to only send emails in plain text?

Currently seen a video with a developer for an email service provider, and he mentioned that if an email has any HTML, email service providers will send them to spam. This is concerning cold emails.

Another guy said his replies went through the roof when he started sending cold emails as plain text.

So I just wanted to test this out, also perhaps someone will know more about this.
