What is SMS Merge?

Personalise Every Message Automatically

Using %string1%, %string2% placeholders in your message template, iSMS replaces each tag with the corresponding value from your CSV file for each recipient — delivering a unique, personalised message to every contact.

💡
SMS Merge is ideal for membership renewals, appointment reminders, invoice notices, loyalty rewards, and any campaign where each recipient needs different information.
