When exporting search results or preparing a New Mailing in Civi Mail, there is an option to merge contacts from the same household/address (export) or remove duplicate emails (CiviMail).
- Does a similar merging option exist for a New SMS in CiviSMS?
- If not, what is best practice for preventing multiple SMS going to duplicate phone numbers?
Backstory: Our organization has a large number of families, so parents will often register their children with the parent's mobile number. Thus the high probability of duplicate mobile numbers for mass SMS.
