When you have a big list of contacts in the SMS Mailer and you want to send a message to all of them, you can make a group, import those contacts and use the group to send a message to. However, if this is just a one-time mailing, creating a group is a bit redundant. So, to accomplish sending to all your contacts without using a group, go to SMS Mailer and:
- Go to Contacts
- Choose Contacts
- Click on the middle button saying “Selected (0)”
- Choose “Select all contacts”
- Click on the middle button again
- Choose “New mailing from contacts”.
This will open a new mailing screen, with a yellow banner on top saying “X contacts selected”
Now you can proceed with filling in the necessary fields and send the message as you would normally do.
