Custom email setup

Hi,

So today I started using the plug in, and it works pretty fine for me. The only problem I have is that the message body, the email, is just a plain text with no option to edit. Is it possible to add breaks and customize the message body with something like html? Like:

Dear Customer,

Today I have a new blog post.

Greetings, Glenn

Instead of:

Dear customer, today I have a new blog post. Greetings, Glenn

Thanks in advance.
