Customer Retention

SMS & Text Marketing

Text messages get read in minutes — which makes SMS the most direct channel your business owns, and the one that most demands doing right. We build it consent-first, registered, and compliant.

An SMS marketing agency runs text-message marketing for businesses: appointment reminders, time-limited offers, reactivation nudges, review requests, and two-way conversations — the messages that genuinely can't wait for an inbox. RG Digital Marketing builds SMS programs consent-first, because in text marketing, compliance and performance are the same project: proper express opt-in, A2P 10DLC registration with the carriers, instant opt-out handling, and a cadence that respects the most personal inbox your customer has. Done this way, SMS becomes a direct line to every customer you've ever served; done carelessly, it burns the list and invites real legal exposure. We only do it the first way.

The problem

The most direct channel a business owns — and the easiest to burn

Text messages get seen. That's the entire appeal, and the entire risk. A customer who tolerates a mediocre email will not tolerate a spammy text — one careless campaign and they opt out forever, or worse, report you. And the stakes aren't just reputational: texting without proper express consent violates the TCPA, and unregistered business texting gets filtered or blocked by the carriers before it's ever delivered. Most businesses either avoid SMS entirely — leaving their most immediate channel unused — or wing it with a cheap blasting tool and quietly poison their own list. The channel rewards exactly one approach: permission, registration, restraint.

We build the whole system: compliant opt-in capture at every touchpoint, A2P 10DLC brand and campaign registration, the automated messages that earn their interruption — reminders, review requests, time-limited offers, win-backs — and two-way texting routed into your CRM so replies become conversations, not dead ends.

The stack

Registered, routed, and wired to your CRM.

What's included

Everything in SMS & Text Marketing.

Compliant opt-in capture

Express consent collected properly at forms, checkouts, and intake — with the disclosure language and records that make the program defensible.

A2P 10DLC registration

Brand and campaign registration with the carriers, done before the first send — the difference between delivered texts and silently filtered ones.

The right message types

Reminders, time-limited offers, review requests, reactivation nudges, missed-call text-back — messages that earn the interruption.

Two-way conversations

Replies route into your CRM and to a human when it matters — because a text your customer answers is a lead, not a broadcast.

Cadence & quiet hours

Frequency caps, quiet-hour windows, and segmentation so the channel stays welcome — restraint is what keeps SMS performing.

Instant opt-out handling

STOP honored immediately and synced across every system, with suppression lists that keep it that way.

How it works

From click to customer.

Consent & compliance audit

What consent do you actually have, and for what? We audit your list's opt-in status and set up compliant capture going forward — nothing gets sent to anyone who didn't ask.

Register & configure

A2P 10DLC brand and campaign registration, number provisioning, opt-out automation, and CRM routing — the infrastructure layer done right.

Build the automations

The always-on texts that produce: reminders, review requests, missed-call text-back, win-backs — each triggered by a real event in your business.

Send, measure, restrain

Campaigns on a disciplined cadence, measured to revenue and opt-out rate — the two numbers that tell you whether the channel is being used or used up.

In SMS, compliance is the performance strategy

Text marketing is one of the few channels where the legal requirements and the marketing best practices are the same list. The TCPA requires express consent — which is also what guarantees your audience actually wants your texts. Carriers require A2P 10DLC registration — which is also what gets your messages delivered instead of filtered. Honoring opt-outs instantly is the law — and it's also what protects the rest of your list from a spam-report spiral. Businesses that treat compliance as red tape end up with blocked numbers and burned audiences; businesses that build consent-first end up with the rarest thing in marketing: a channel where nearly every recipient chose to be there. That's why our SMS engagements start with the consent audit and the registration, not the first campaign.

What SMS is for — and what it isn't

The way to keep a text channel alive is to respect what it's uniquely good at: immediacy. A reminder the morning of the appointment. A review request an hour after a great job. A genuinely time-limited offer. A text-back within seconds of a missed call. A short nudge to a customer who's gone quiet. These messages perform because a text is read now — and they stay welcome because each one is obviously useful. What kills the channel is treating it like a second email list: newsletters, long pitches, anything that could have waited. We pair SMS with email deliberately — email carries depth and frequency, SMS carries urgency — so each channel does its job and neither wears out its welcome.

The fastest text is automatic

Missed a call? The text-back already sent.

The highest-value text most businesses can send is the one that goes out seconds after a missed call or new inquiry — before the prospect dials the next name on the list. That's the AI lead response layer: instant engagement, qualification, and booking, with SMS as its front channel.

Common questions

Good to know.

Is SMS marketing legal?

Yes, with express consent. In the US, the TCPA requires that recipients opt in before you text them for marketing, and that opt-outs are honored immediately. On top of that, carriers require A2P 10DLC registration — verifying your business and campaigns — before allowing volume texting. We build all of it in from day one, because a compliant program is also the one that actually gets delivered.

What is A2P 10DLC?

It's the carrier registration system for business texting in the US — 'application-to-person' messaging over standard 10-digit long-code numbers. Businesses register their brand and their campaign types with the carriers; registered traffic gets delivered reliably, unregistered traffic gets filtered or blocked. If a business is texting at any volume without it, their messages are quietly not arriving. Registration is one of the first things we set up.

Can I text my existing customer list?

Only the ones who gave express consent to receive texts — a customer relationship alone isn't texting permission under the TCPA. If your list doesn't have clean SMS consent, we run a permission pass first (usually via email) inviting people to opt in, and we build proper capture at every new touchpoint so the compliant list grows from here.

How many texts are too many?

Fewer than you think. SMS earns its power from restraint — for most service businesses that's a handful of automated, event-triggered texts per customer (reminders, review requests, the occasional offer) rather than a weekly broadcast. We watch opt-out rate as closely as revenue: it's the earliest warning that the cadence is wearing out its welcome.

What should a business actually send by text?

The messages that can't wait: appointment and job reminders, missed-call text-backs, review requests right after a good experience, genuinely time-limited offers, and short win-back nudges. Anything longer or less urgent belongs in email. The test for every SMS is simple — would the customer be glad this arrived as a text right now?

How is SMS marketing measured?

Revenue and list health. Each automated text and campaign is attributed to the bookings, reorders, or reviews it produced through your CRM — and alongside it we track delivery and opt-out rates, which tell you whether the channel is being maintained or mined. Both numbers report in the same dashboard as your email program.
