Understanding Campaign Message Options (WA API & WA Personal)
When saving a campaign message, you will see two options:
Apply to All (Old and New Enrolled Contacts)
Apply to New Enrolled Contacts Only
These options decide who will receive your message, especially when you create or update a campaign.
There Are 2 Situations
When saving a campaign message, it depends on what you are doing:
Creating a New Message
Updating an Existing Message
1. New Message
This is when you are creating a message for the first time.
Apply to All
The message will be scheduled for all current contacts
Everyone will receive the message
Example:
You have 100 contacts
👉 All 100 contacts will receive the message
Apply to New
Only new contacts added after this will receive the message
Existing contacts will not receive anything
Example:
You create the message today
After saving, 100 new contacts was enrolled
👉 Only the 100 new contacts will receive the message
2. Update Existing Message
This is when you edit a message that was already created.
Apply to All
Contacts who have not received the message:
