I few months ago, I tried to use the Mass Email Sender plugin, and found out that the emails sent out jammed all the words together in one paragraph. This was because the plugin did not allow html in the email.
I would like to find out if the developer has made any improvement to this functionality so we can at least add line breaks and paragraph returns when we compose our emails.
Also, I noticed the user name was inserted, but this looks bad addressing to a username and not a real person's name. I would like to see this ability added also.
