Rated 5 out of 5 stars

An excellent add-on which adds features that are essential but missing from TB. Every other email client had them in 1995...

One request: Add a new reserved word %firstname%. Most of my email is between my friends and me, and when replying I prefer to just use their first name (given name):

Hi Paul,

This review is for a previous version of the add-on (0.4.3). 

I'm sorry. I can not support %firstname%, because there are no ways to specify the first name correctly and in some languages, the name might be written as "family-name first-name".
Furthermore, it is too difficult for me to cooperate with an address book.

Best Regards.
