Hello. I use the following iso app to text every month. It splits the messages into how ever many contacts I import, like a mail merge so no one sees that I'm actually sending a group text. Here is the link to the iOs app store entry

https://itunes.apple.com/us/app/group-text/id377826584?mt=8

I need to actually send out a message in April to a group of contacts and I use group text, the name of the app in the link, to do this to make it easier. Is there a similar app for android that will do this?
