So currently, MyBB sends all its system emails as plaintext. I have a template ready, but I don't know how to change it so that MyBB sends HTML emails with a plaintext alternative, like most normal email campaigns. How can I do this?

replies here might help

Thanks. Unfortunately, this doesn't mention how to send both the HTML and plaintext version as an alternative, meaning it's liable to be picked up by spam filters.
