Permission-led SMS marketing process showing opt-in, segmentation, concise messaging, scheduling, replies and conversion

SMS Marketing ServicesRead in three minutes.
Not three days.

SMS is the only channel where a message is almost certainly read within minutes. That makes it extraordinarily powerful and extraordinarily easy to abuse. Our SMS marketing services build compliant, permission-led programmes that drive revenue without burning the list.

01
What we actually do

Fewer messages, better targeted, legally clean.

SMS marketing done properly is a restraint exercise. The technical setup is straightforward; the discipline is deciding what genuinely deserves an interruption.

We build the consent infrastructure that keeps you compliant, the segmentation that makes each send relevant, and the automation that handles the moments where SMS genuinely outperforms every other channel — cart recovery, delivery updates, appointment reminders and time-boxed offers.

The scarcity principle: SMS permission is finite and non-renewable. Every send spends a little of it. Programmes that send less, better, keep producing for years; programmes that maximise volume burn the list inside two quarters.

What’s included

Five systems we build and run for you

Every engagement covers all five. Automated, behaviour-triggered messages sit at the centre — the rest keep your list compliant, relevant and profitable.

The Sachkhand blueprint

How we build an SMS programme that lasts

Six workstreams, compliance first — because a consent problem discovered later invalidates the whole list.

Phase 1FoundationMake every message legal, consented and sent to the right segment.
  1. 01

    Consent & compliance audit

    How permission was collected, whether records exist, and whether it meets the standard in each market you send to. This comes first because everything downstream depends on the list being lawful.

  2. 02

    Segmentation

    Lists split by lifecycle stage, purchase behaviour and engagement so a send is relevant to the person receiving it rather than to the average of your database.

Phase 2BuildAutomate the moments that matter and cap how often anyone hears from you.
  1. 03

    High-value automation

    Cart recovery, back-in-stock alerts, appointment reminders and delivery updates — triggered by behaviour, and the messages customers actively want.

  2. 04

    Frequency governance

    Send caps, quiet hours and cross-channel coordination so SMS and email are not both firing at the same person on the same day.

Phase 3OptimiseSharpen the copy and prove revenue per send, month after month.
  1. 05

    Copy that respects the format

    160 characters, one clear action, no ambiguity about who is messaging. Long, chatty SMS gets opted out of.

  2. 06

    Attribution & churn tracking

    Revenue per send, opt-out rate per campaign, and list health trended monthly so decline is visible before the list is damaged.

ⓘ Consent is audited before a single message is sent — each phase starts only when the one before it is healthy.

03
What is changing through 2026

Four shifts in messaging

Regulation is tightening and the channel is broadening beyond plain SMS. Both change how programmes should be built.

01

RCS is replacing plain SMS

Rich Communication Services brings images, carousels, verified sender branding and read receipts to the default messaging app. Programmes built on plain SMS will need to adapt, and early adopters get a visual advantage.

02

Sender verification is becoming standard

Verified sender IDs and brand registration reduce spoofing and improve trust, but require registration and approval. Unregistered senders increasingly get filtered.

03

Regulators are enforcing more actively

Consent standards for SMS are being enforced with real penalties. Bundled or implied consent that passed unchallenged for years is now a genuine liability.

04

Conversational messaging is growing

Two-way SMS for support, booking and reordering converts far better than broadcast, and customers increasingly expect the ability to reply.

Compliance is not optional

We audit consent before sending anything. A list collected improperly is a liability rather than an asset, and no amount of revenue justifies that exposure.

Frequency caps enforced

Set at platform level, not left to whoever schedules the campaign. Opt-out rate is a KPI we manage down rather than accept.

Automation over broadcast

The highest-returning SMS is triggered by behaviour the customer just took. Broadcast is the fallback, not the strategy.

Provable revenue

Unique tracked links per campaign so SMS revenue is attributable. Programmes without attribution get cut in the first budget review.

Coordinated with email

SMS and email planned together so a customer is not receiving both on the same day about the same thing.

List health over list size

We track opt-out rate weekly. A shrinking, engaged list outperforms a large, resentful one every time.

05 The honest comparison

Why businesses choose SDM for SMS marketing

Same budget, very different outcomes. Point by point, here’s how a specialist partner compares to a typical agency or doing it in-house.

Measurement

Opt-out rate matters as much as revenue

A campaign that makes money and costs you 4% of the list is not a success. We report both together.

Revenue per send

Attributed revenue divided by messages delivered, net of send cost — the true return on each interruption.

Opt-out rate per campaign

Tracked per send so the messages that damage the list are identified and not repeated.

Automation vs broadcast split

How much revenue comes from behaviour-triggered messages versus scheduled broadcasts.

Click-to-conversion rate

What happens after the tap, since SMS click rates flatter programmes that convert poorly.

Net list growth

Opt-ins minus opt-outs, so growth is not overstated by counting only new subscribers.

07
The engagement

Our SMS Marketing process: four stages, repeated every month

Compliance, then automation, then volume — in that order, always.

  1. 01

    Audit consent

    How permission was captured, whether records exist and whether it meets the standard in each market. Any list segment that fails is suppressed before we send.

    Compliant, defensible list
  2. 02

    Build automation

    Cart recovery, back-in-stock, reminders and delivery updates — the triggered messages customers want, which produce most of the revenue.

    Always-on SMS revenue
  3. 03

    Govern frequency

    Caps, quiet hours and coordination with the email calendar so no customer is over-messaged across channels.

    Opt-out rate under control
  4. 04

    Test & report

    Copy, timing and offer testing with attribution per campaign, reported alongside opt-out rate so revenue is never celebrated in isolation.

    Provable, sustainable growth
Outcomes

The targets we set for SMS engagements

Targets we plan against for ecommerce, hospitality and appointment-based clients after six months.

  • +142%SMS revenueTarget by month 6
  • 0.4%Opt-out ratePer campaign
  • 64%Revenue from automationvs broadcast
  • 18%Click-through rateAcross programmes

Targets, not best cases. SMS returns depend heavily on how the list was built and how disciplined the send calendar is. Lists collected with bundled consent frequently need substantial suppression before any sending, which lowers early volume but protects the programme. These are planning targets rather than a record of past client averages; we agree a realistic range against your own baseline before an engagement starts.

Questions

SMS Marketing FAQs: the questions we get asked most

Direct answers on compliance, frequency and what SMS should actually be used for.

How often should we send SMS?+

For most businesses, between one and four times a month for broadcast, plus behaviour-triggered automation which can be more frequent because the customer just took an action. The exact number depends on your category and how the list was built. What we can say confidently is that weekly broadcast to a full list is where most programmes start losing subscribers faster than they gain them.

What consent do we actually need?+

In most markets, explicit and unbundled — the person must specifically agree to marketing SMS, separately from accepting terms or making a purchase, and you must be able to evidence it. Implied consent from a transaction is not sufficient for marketing messages. We audit this first, because a list collected improperly is a liability rather than an asset.

Is SMS better than email?+

Different, not better. SMS gets read almost immediately, which makes it right for time-critical and high-value messages. Email is cheaper, non-intrusive and suits longer content and regular contact. The programmes that work best use both deliberately — email for the majority, SMS for the moments where minutes matter.

What should we actually send by SMS?+

Anything where immediacy genuinely changes the outcome: cart recovery, back-in-stock alerts, appointment reminders, delivery updates, time-boxed offers and service disruptions. If the same message would work equally well as an email tomorrow, send it as an email — SMS permission is too scarce to spend on it.

How do we track whether it is working?+

Unique tracked links per campaign, so SMS revenue is attributed rather than absorbed into direct traffic. Without that, SMS gets cut in budget reviews because nobody can prove it earned anything. We report revenue per send alongside opt-out rate, because a profitable campaign that costs 4% of the list is not actually a success.

What about RCS?+

It is coming and worth preparing for. RCS brings images, carousels, verified branding and read receipts to the default messaging app, which makes messages considerably richer. Adoption varies by market and handset, so we build programmes that work as plain SMS and progressively enhance where RCS is supported.

How quickly will we see results?+

Triggered automation produces revenue as soon as it goes live, because it fires on behaviour already happening. Broadcast improvements show within the first month or two. If the consent audit reveals problems, expect a slower start — suppressing and re-permissioning a list costs short-term volume but protects the programme.
