Your business

Trade picks the template style

Business name

Owner first name optional, used in 1 template

Response promise minutes, default 5

Booking link optional — Calendly / Google form / your site

Hours phrasing used in after-hours template

TCPA opt-out footer appended to every template; default ON; recommended

Most US carriers (T-Mobile, AT&T, Verizon) require an opt-out keyword on Application-to-Person SMS. Default STOP=opt out is 13 chars and CTIA-recognized. See TCPA notes below.

Your 5 templates

Each is sized to fit one SMS segment (≤160 chars). Pick one for your default auto-reply, rotate for variety, or A/B test 2 against each other.

How to use these

Three ways, ranked by setup effort:

iPhone Focus auto-reply — Settings → Focus → Driving → Auto-Reply → "All Contacts" → paste template. Free. Zero setup time. Limitation: only fires when phone is in Driving Focus, and replies use your iCloud number, not your business number.
Android Auto-Reply / Bixby Routines — Routines app → "When I miss a call" → "Send SMS" → paste template. Free. Limitation: only triggers when phone is on you and missed the ring.
SMS auto-reply tool — Enzak ($99/mo + $99 setup), NextPhone ($199/mo unlimited), or any tool that supports custom templates. Triggers automatically when your business line misses a call, regardless of where you are.

For trade-specific patterns: HVAC and plumbing buyers expect a clear ETA; electrical and roofing buyers expect to schedule a quote, not get instant work. Templates below reflect that.

Why 160 chars matters

SMS messages over 160 GSM-7 chars get split into multi-segment messages and billed per segment. They also display as "delivered later" on some carriers. Generators that produce 200-char "templates" are giving you a hidden cost you'll notice on month two.

Each template below shows its char count. Anything in red is over 160 — usually because your business name + booking URL is long. Trim or remove the booking line if so.

TCPA & carrier compliance — what the opt-out footer is for

Auto-replying to a missed inbound call with a text is generally not a TCPA solicitation under the FCC's responsive-communication doctrine — the consumer initiated the call, so an immediate text reply about that same call is treated as in-scope. Two practical rules every template here follows when the footer toggle is ON:

Opt-out keyword — major US carriers (T-Mobile, AT&T, Verizon) require Application-to-Person SMS to honor STOP / UNSUBSCRIBE / CANCEL / QUIT / END. The default footer STOP=opt out (13 chars) signals this without blowing your 160-char budget. You can replace it with any wording your tool's compliance team prefers (e.g. Reply STOP to opt out. at 23 chars).
Sender identity — every template already includes your business name (${business}), so the CTIA sender-ID expectation is met without an extra string.

This generator does NOT make you compliant by itself — your SMS sending tool needs A2P 10DLC registration, STOP-keyword auto-responder, and a HELP-keyword auto-responder. This footer just makes sure the message body is shaped the way carriers want.

Not legal advice. Don't use these templates for marketing follow-up to people who didn't call you.

What makes a missed-call text-back actually convert

Industry data on missed-call text-back: 78% of callers hang up at voicemail. 85% of unreturned missed callers never call back. Of those, ~50% will reply to a same-minute text within 5 minutes. Three things move the conversion needle:

Speed — same-minute beats 5-minute beats 30-minute. Anything over 30 minutes is functionally a voicemail.
Specific next step — "tap here to book" beats "we'll call back" because the caller is still in buying mindset for ~5 minutes.
Trade-specific phrasing — "ETA on a tech" for HVAC; "free roof inspection" for roofing. Generic "we missed you" is ignorable.

Templates 2 and 3 below are built for #2 (booking-link version) and #3 (trade-specific phrasing).
