Text as a second channel, not a separate one

A phone call doesn't always end the moment it ends. Harmony.ai can follow a call with a text from the same number - a booking confirmation the moment you hang up, a reminder the day before, or a link to reschedule if a slot didn't work. If a caller doesn't pick up at all, the agent can text instead of leaving a voicemail that goes unheard.

What it handles

Confirmations and reminders reduce no-shows without a person typing them out one at a time. A payment or scheduling link can go out mid-call so the caller finishes the action on their own phone. Opt-outs are honored automatically - a caller who replies STOP stops getting texted, full stop.

Where it shows up

Every text sent or received logs to the same record as the call, so a rep or front desk sees the full thread - call, text, call - in one place instead of two systems that don't talk to each other.

Follow up every call with a text

Harmony.ai sends confirmations, reminders, and links from the same number it answers on, so nothing depends on a callback.

01

Connect the number

SMS runs on the same number your voice agent already answers on, texting enabled alongside calls.

02

Sync the thread

Texts attach to the same caller record as the call, so nothing about the conversation is split across systems.

03

Send with purpose

Confirmations, reminders, and reschedule or payment links go out automatically around the call.

04

Hand off in context

Every message logs alongside the call transcript, and opt-outs are honored the moment a caller replies STOP.

Frequently asked questions

Harmony.ai can text callers from the same number the voice agent answers on, sending booking confirmations, appointment reminders, and reschedule or payment links before or after a call, without a person typing them out.

No. SMS is a follow-up channel built around the call, not a replacement for it, used for confirmations, reminders, links, and as a fallback message when a call goes unanswered instead of a voicemail nobody checks.

Yes. A caller who replies STOP is removed from future texts immediately, and that preference is tracked against their record so no one on your team has to manage opt-outs by hand or keep a separate list. That consistency matters once call volume is high enough that no one has time to check each one by hand.

Yes. Messages sent or received attach to the same caller record as the call, so anyone reviewing the record afterward sees the full conversation, call and texts together, in one continuous place. That consistency matters once call volume is high enough that no one has time to check each one by hand.

Teams already running Harmony.ai for voice at real call volume who want confirmations and reminders to go out automatically instead of a person sending each one individually by hand. That consistency matters once call volume is high enough that no one has time to check each one by hand.
