I need to black list messages from email accounts based on the domain such as "@tmomail.net"

Yes a blacklist is already inputted but it needs to be more developed. Allow us to see the blocked message in their own window if wanted. Also allow us to blacklist someone from the phone's contacts instead of just the conversation list

We need to way to manually add numbers without having a message already present in order to blacklist them

If you have blacklisted a number, will you get msgs they have sent after removing them from your blacklist???

This feature does exist now if you hold down on an SMS conversation, go into the drop down menu and select blacklist

already exists

Chomp does - why not Textra?

yes this is a must

yes this is a must

how do you blacklist/block a number?? this should be very basic!
