SMS Fusion is a cloud-based text messaging gateway that allows businesses to send automated SMS communications to customers.
TriggersTriggers when a new contact is added to a list.
Triggers when a delivery report is received for a sent SMS.
Triggers when a tracked link in a campaign message is clicked.
Triggers when an SMS is received to an inbox or virtual number.
Triggers when an SMS is sent. Caution: chaining this to an SMS-sending action can create an infinite loop, since automated sends are indistinguishable from human ones. Use a Filter step to break the cycle.
Add a contact to a list. Insert-only despite the name - see help text below. This does not update an existing contact, and a replayed run can create a duplicate.
Cancel a pending or in-review campaign before it sends.
Cancel a previously scheduled SMS before it sends.
Delete a contact by mobile number, from one list or from all of your lists at once. Destructive - deletes every matching row, with no undo.
Formats and validates a phone number: returns its MSISDN/E.164 form, country, carrier, and mobile/validity flags. Read-only lookup, no cost or side effects - safe to use as a formatting step mid-Zap.
Looks up the recent SMS history (sent and received, newest first) for a single mobile number.

Common questions about SMS Fusion + Call Assist
Is there a pre-built SMS Fusion + Call Assist automation?
Not yet, but Knit's Integrations Agent can build one — describe what you want and it researches SMS Fusion and Call Assist's public API docs (or your own uploaded docs) and builds a working automation.
Does this require a pre-built SMS Fusion or Call Assist connector?
No. The Agent works whether or not SMS Fusion or Call Assist already has a pre-built connector in Knit's catalog — it researches the real API surface either way.
How long does it take to build?
Minutes to build a first working version, not weeks — you test it against real data before it goes anywhere near production.
Why connect two different phone and SMS platforms?
Linking SMS Fusion with Call Assist lets teams bridge separate communication systems, cross-notify staff about missed calls, and keep contact records consistent across carriers.
Can I automatically send texts from one platform when calls are missed on another?
Yes, a missed call detected in SMS Fusion can immediately instruct Call Assist to dispatch an automated text reply.
