Massive sender (text messages and emails)

Hello again Tadabase Community, thanks for all your support!

This time I want to build a mass sender for messages (using twilio maybe?) and emails (using sendgrind maybe?). Basically the use case is to write in a form the message and pull the phone number and email fields from a data table that stores them (I mean, like looping through all of the stored records). Is that possible? What would be the approach for building this?

Many thanks in advance!
