Sending bulk SMS through the send SMS popup allows you to utilise several key features of the SMS popup for these communications including:
Loading an SMS template
Adding associations (the communication will show on each activity feed of each association)
Using merge field tags from both the contact and associated records
Schedule a follow up task in the same action
Differences between bulk SMS through the popup and a bulk SMS campaign
Sending bulk SMS through the send SMS popup is slightly different to an SMS campaign:
There is no campaign report, however you can see SMS that have been sent and delivered on the contact activity feed like you would for any other SMS
Unless you view the contacts first on the contacts screen, you can't exclude recipients
There is a maximum of 100 SMS recipients per SMS and we recommend using it for targeted communications only (bulk SMS campaigns do not have a limit)
Bulk SMS sent through the send SMS popup are subject to contact subscriber settings as a normal bulk SMS campaign. Whereas Subscriber settings do not apply for a singular SMS sent through the send SMS popup.
