A text can change the outcome.
A pipe lets go on a Saturday night, the customer rings three plumbers, and agrees to a fee on the phone with whoever answers first. The rate lands in a text before the van moves, so the price at the door is the one they already said yes to.
Plumbing messages. And all of the others.
Every message category is included — one registration.
Confirms the job when it's booked, reminds the customer of the arrival window the day before and the morning of, texts when the technician leaves for their door, and offers a rebook if nobody was home.
Marks the visit complete, sends the invoice with a pay link, nudges the customer if it goes unpaid, and asks for a review while the work is fresh.
Confirms a moved or cancelled visit and gives the customer a link to rebook.
Common questions
Does the service-call fee belong in the booking text?
If you charge one, yes.
More detail
A fee said on the phone is easy to forget by the time the plumber knocks. Putting it next to the time slot settles it before anyone drives, including whether it's waived when the customer goes ahead with the repair.
Should the plumber call ahead, or text?
Text first, and call if nobody answers.
More detail
Most plumbers won't roll to an empty house. A text with the arrival time gets a reply faster than a voicemail, and the call is still there for the customer who doesn't answer.
When do I ask users if it's okay to text them?
Right when they give you their phone number for the first time.
More detail
For plumbing, that's usually when the customer books the call or asks for an emergency visit. That's when texting makes sense to them and the ask feels natural. Your AI tool adds the opt-in ask right there: a line under the phone field saying what texts they'll get. RelayKit gives it the wording.
You build the feature. We handle the bureaucracy.
Every text message carries a stack of carrier rules. We've read all of it, so you don't have to.
Registration handled
Getting approved on your own can take weeks.
Most registrations clear in about three days. We handle the filing, so you can keep building your app.
Messages compliant
Send the wrong kind of message and carriers block it — silently.
Every message is checked against carrier rules before it sends, not just passed through.
Opt-ins & opt-outs covered
Miss a single STOP and the fines add up fast.
We stop instantly. Consent is tracked and enforced at delivery, not wired up by you.
Give your AI tool a build spec, not a pile of docs.
RelayKit generates implementation instructions for your AI tool. Messages, variables, event triggers, testing steps, and integration guidance arrive for smooth integration.
Slots into ShipFast, Supastarter, MakerKit, and Vercel + Supabase.
import { RelayKit } from 'relaykit'; const relaykit = new RelayKit(); await relaykit.appointments.sendConfirmation(customer.phone, { date: 'Fri, Jun 6', time: '2:00 PM', });
That's the send.

When a message can't wait, send a text.
Messages from an app only work when someone sees them. Here's how text and email compare.
Industry SMS-vs-email benchmarks, 2025–26 — open and response from SMS-marketing aggregates; email inbox placement from Validity's 2025 deliverability report. SMS open is inferred from delivery, not pixel-tracked; reported email open rates are distorted by tracking-pixel prefetch and blocking.
The rules show up after you start building.
US carriers require these from every business that sends texts. Getting approved can take weeks if not done right.
Registration
Before anything sends, your business gets registered in a central registry that every US carrier checks — legal name, tax ID, website, and what you plan to send. Details have to match your IRS records exactly, or the application bounces.
RelayKit collects this during setup and files the registration for you.
Carrier review
Reviewers check your registration and your messages against carrier rules before you're allowed to send. Other providers typically take two to three weeks — and every rejection restarts the clock, with no guarantee the next round clears.
RelayKit submissions are prepared to pass the first time; approval typically takes a few days.
Consent requirements
You have to collect and keep proof that every recipient agreed to get texts from you — how they opted in, when, and which kinds of messages they agreed to. Someone who signed up for appointment reminders hasn't agreed to marketing.
RelayKit provides the opt-in language and keeps the consent records automatically.
Build a compliance website
Reviewers visit your website looking for a privacy policy with specific mobile-data language, posted terms, and a visible description of your texting program. A missing or half-finished site is the single most common reason registrations get rejected.
RelayKit generates and hosts a compliance site for you — privacy policy, terms, and opt-in page included.
STOP and HELP handling
A reply of STOP has to halt messages to that person immediately, and HELP has to get a real answer — automatically, every time. Getting it wrong is a fast way to get a number shut down.
RelayKit handles both at the delivery layer; when someone replies STOP, we stop.
Message restrictions
Carriers limit what businesses can say over text: entire content categories are banned, links get scrutinized, and messages outside your registered use case can get your number flagged. The rules live across multiple carrier policies, and they change.
RelayKit's templates already follow them, and custom messages are checked before they send — not just passed through.
The messages are ready now.
Sending arrives Summer 2026.
You can start with the messages today. When sending launches, your AI tool wires up the integration, you test on real phones, and registration and opt-outs stay handled behind the scenes.
