The SMS Follow-Up Sequence Most Service Businesses Forget to Send

Here's an uncomfortable truth: a decent chunk of your leads are reading your follow-up emails exactly never. Not because they're not interested — because email has become the place good intentions go to die, buried under newsletters and promotions they meant to unsubscribe from. A text message, by contrast, still gets read within minutes for most people. If your entire follow-up plan lives in the inbox, you're relying on a channel that a lot of leads have quietly stopped paying attention to 💖.

What most businesses get wrong

The usual excuse for skipping SMS follow-up is "it feels too pushy" or "we don't want to spam people." Those are fair instincts, but they usually come from imagining SMS as a sales channel rather than what it actually works best as here: a gentle, short, easy-to-ignore nudge that happens to land somewhere people actually look. The businesses that do use SMS tend to either overdo it (daily texts, hard sell) or set it up once and forget the compliance wording — both of which cause real problems, just different ones.

Under Australia's Spam Act, commercial electronic messages including SMS need consent, a clear sender identity, and a working opt-out — this isn't optional small print, it's a legal requirement, and it needs to be baked into the sequence from message one, not bolted on as an afterthought.

How to actually set this up

Start with consent: your enquiry form needs an explicit checkbox or statement that SMS follow-up may be used, separate from (not bundled into) general terms and conditions — bundling it in is a common shortcut that doesn't hold up well if someone complains. Every message needs your business clearly identified and a working, immediate opt-out (STOP is the standard, and it needs to actually work the moment someone replies, not "within 5 business days").

Most SMS platforms that integrate with a CRM or form tool can automate this sequence based on time-since-enquiry triggers, so once it's built it runs without anyone remembering to send anything manually. Keep messages genuinely short — SMS loses its advantage the moment it starts reading like an email crammed into a text box. If you haven't got a broader follow-up structure in place yet, our piece on the follow-up cadence for "I'll think about it" leads pairs well with this as the email side of the same system.

• Don't send SMS without clear, separately captured consent — bundling it into generic terms isn't good enough.
• Don't skip the opt-out line on any message in the sequence, including the first one.
• Don't run the full four-text sequence for every type of lead — adjust tone and frequency to fit how formal the relationship is.
• Don't use SMS for anything beyond short, functional nudges — it's the wrong channel for detailed information.
• Don't ignore STOP replies immediately — a delayed opt-out is both a compliance risk and a trust-breaker.

Frequently asked questions

Is SMS follow-up actually legal in Australia?

Yes, provided it meets Spam Act requirements: consent, clear sender identification, and a working unsubscribe mechanism. It's the same basic framework as email marketing, just applied to a different channel.

Will SMS annoy people more than email does?

It can, if overused — and that's a genuine trade-off worth weighing. SMS has a lower tolerance for frequency than email; three texts in a week will feel like a lot more pressure than three emails in the same period, so keep the sequence shorter and more spaced out.

Do I need special software, or can I just text people manually?

Manual works at small volume, but it doesn't scale and makes consistent opt-out handling harder to guarantee. Most businesses sending this regularly end up on a dedicated SMS or CRM platform once volume grows past a handful of leads a week.

Should every lead get the same sequence?

No — adjust based on how the lead came in and how formal the relationship is. A casual enquiry and a high-value, considered purchase warrant different tones and different message counts, even within the same business.
