Currently, the e-mail subject line only can contain 255 characters. If you put an ampersand in your subject line, it gets converted to & and takes up 4 extra slots. When doing conditional subject lines, this is not enough characters to really target the groups. I am trying to target nine groups, but would like to do more, but am limited to this character width. I am trying to include many teamraiser groups and a few other ones and really do not want to have to import them all into another group.
