Sending a message with, for instance, the name of the recipient in the message, is more personal. For instance:
Hi, your product is ready.
Hi Dennis, your product is ready.
You can just feel the difference when reading both messages.
Implementing this is very easy.
Open SMS Mailer. Go to:
On the bottom of the screen, you will find placeholders. Click on a placeholder to add it to your message.
You can add other custom fields/placeholders by going to Settings > Custom Fields.
The information is coming from your contacts, so if you are going to test this, make sure you have at least a few contacts/groups defined in Portal.
