Missed-call text-back

Updated 2026-09-19

Missed-call text-back sends a text to any caller you did not answer, within seconds, asking how you can help. On HighLevel it runs as a workflow tied to a registered number and costs one message segment per reply sent. It pays for a business that misses calls while working; it does nothing for a business where the phone is always answered.

How it works

HighLevel's missed-call text-back automatically sends a text whenever an inbound call goes unanswered, and repeated missed calls from the same caller within a short window each trigger their own message (source: help.gohighlevel.com, checked September 2026). The message is sent through the phone number the call came in on, so the reply appears to come from the same number the caller just dialed.

What has to be true first

The number receiving calls needs to be a registered HighLevel number, or a number forwarded into one, with A2P 10DLC registration completed for SMS to send reliably in the US (see phone and SMS). Registration is a one-time process with its own fee and a short processing window; skipping it risks carriers filtering the automated text before it reaches the caller. Confirm registration is complete before turning the workflow on, not after the first missed call.

What it costs

The workflow itself carries no separate fee beyond the plan. Each text sent draws from the standard SMS rate, $0.00747 per segment for US and Canada as at September 2026, with a segment covering up to 160 characters (see usage fees). A short reply is one segment; the cost per missed call is close to a cent. For a business missing a dozen calls a week, the monthly SMS cost of this workflow is negligible against the value of even one recovered enquiry.

The arithmetic

Work it out with your own numbers rather than an assumed benchmark: count missed calls in a typical week, estimate what one of those calls is worth if it becomes a job, and compare that to the SMS cost of a text-back for every one of them. For most local service and trades businesses, one recovered job a month covers a very large number of missed-call texts.

What the message should say

Keep the reply a question, not a pitch: something close to "Sorry we missed your call, how can we help?" invites a response and keeps the conversation with a real person. A message that opens with an offer or a sales line reads as an obvious automation and can cost the reply it was meant to save.

Who it does nothing for

If a receptionist or a team member answers every incoming call, this workflow has nothing to catch. It also does nothing for a business whose customers do not call in the first place, such as one that runs entirely on email or a booking page. It pairs well with Voice AI for a business where a caller needs an actual answer rather than a text; see AI features for that step up.

Questions people ask

What is missed-call text-back?

An automatic text sent to a caller within seconds of a missed call, asking how the business can help, so the enquiry does not go silent.

How do I set it up in HighLevel?

Confirm the receiving number is registered for SMS, then turn on the missed-call workflow against that number and write a short, direct reply message.

What does each text cost?

$0.00747 per segment as at September 2026, with most reply messages fitting in a single segment.

Does it work with my existing number?

Yes, once that number is forwarded into HighLevel or ported and registered for messaging; an unregistered number risks the text being filtered by carriers.

Is it legal to text callers back?

Rules on automated texting vary by jurisdiction and by consent already on file; check current guidance for your state and industry before relying on this without review, particularly for regulated sectors.
