A typical personal-injury firm drops between 25% and 40% of its inbound calls during business hours. The receptionist is on another line, the answering service hands off poorly, the call comes in during a deposition. Every dropped call is a $40,000 case lost to whichever competitor the prospect dials next.
A single automated SMS sent within 30 seconds of the missed call recovers 25-35% of those leads on average.
Why it works
When a person decides to call a law firm, they are at peak buying intent. They have just had an accident, a spouse just left, a tax notice arrived. They will call the next firm in 20 minutes if you do not answer. The window is small.
A text-back arriving 30 seconds after their dropped call does three things at once: acknowledges the firm tried to respond, removes the social cost of re-dialing (text replies feel lower-stakes than calling), and gives them a one-tap action.
95% of cell-phone owners read SMS within 5 minutes. No other channel matches that latency.
The build
Three pieces.
Trigger: the intake-automation platform native "Missed Call" trigger fires when an inbound call to the firm tracked number rings out without connecting.
Action 1 — Wait 30 seconds. Faster (10 seconds) feels robotic and creepy. Slower (2 min) and the prospect has already moved on.
Action 2 — Send SMS. Body: "Sorry we missed you at {{location.name}}. We help with {{case_type}} cases — reply here and we will call back in 15 min, or grab a time directly: {{booking_url}}". Has a name, a specific value prop, two next-step options.
Action 3 — Create a contact + opportunity. Tag with missed-call-{date}, route to the New Leads pipeline.
The math
For a small personal-injury firm getting 80 inbound calls per month: 30% drop rate = 24 missed calls. 30% SMS recovery = 7 recovered consults. 25% sign rate = ~2 signed cases. $40,000 average case value = ~$80,000/year in incremental revenue.
From one workflow that takes 90 minutes to build.
What goes wrong
Three common screw-ups: no A2P 10DLC registration (US carriers throttle untrusted senders); generic stock SMS copy that reads as spam; no human watching for positive replies.
