I have 1003 contacts in my org and I want to send them all an email. I'm limited to 250 contacts per mass email, so I would like to create lists that would split my contacts (and future contacts) to groups, lets say based on the first letter of the Last Name. So for example A-F, G-L, etc...
The problem is that the filter in the mass email contacts only supports AND and not OR. The campaign filter is the same.
Any suggestion how I can solve this and create lists that include about 200 contacts each so they'll be ready for new contacts that are added with time?
