Most leads go cold because nobody follows up fast enough, or consistently enough. A prospect fills in your contact form on a Tuesday, you're flat out with jobs, and by Thursday you've forgotten they exist. By the time you send a message Friday, they've already signed with someone else.

SMS drip campaigns fix this. Set them up once, and every new lead gets a structured, timed sequence of messages automatically, without you lifting a finger. This guide covers how SMS drip campaigns work in Australia, what to put in each message, and how to build sequences that convert without annoying people.

What an SMS Drip Campaign Actually Is

A drip campaign is a series of pre-written messages sent to contacts at set intervals after a trigger event. The trigger might be a form submission, a purchase, a booking, or someone opting in to your list. From that point, the sequence runs on its own.

Compare that to a broadcast: a broadcast is one message sent to many people at once. A drip sequence is personalised and timed, designed to move a single contact through a journey at their own pace.

The autopilot nature is the whole point. Your new lead hears from you at day one, day three, day seven, and day fourteen, even when you're on a job, in a meeting, or asleep. That consistency is what separates businesses with high conversion rates from ones that rely on memory and good intentions.

SMS is particularly well suited to drip sequences because open rates sit above 90 per cent and most messages are read within a few minutes of delivery. Compare that to email, where getting a 30 per cent open rate is considered a win. If you want leads to actually see your follow-ups, SMS is the channel that cuts through.

When to Use a Drip Sequence vs a One-Off Blast

Not every SMS campaign needs to be a drip. Use a broadcast when you have a time-sensitive offer or news for your full list. Use a drip when you want to guide someone through a process over time.

Good use cases for drip sequences include:

• New lead nurturing after a quote request or form fill
• Post-purchase onboarding for new customers
• Re-engagement sequences for contacts who haven't bought in 60-plus days
• Trial or free plan users who haven't upgraded
• Event attendees before and after the event
• Abandoned enquiries where the lead went quiet mid-conversation

The common thread is that you have a contact at a known stage of the journey and you want to move them to the next one through a series of touchpoints. That's exactly what drip sequences are built for.

How to Structure an SMS Drip Sequence for Lead Nurturing

Most high-performing lead nurture sequences follow a pattern: welcome, value, proof, offer. Four to six messages spread over one to two weeks is a solid starting point. Here's what that looks like in practice for a service business.

Message 1 (immediately after opt-in or enquiry):

"Hi [Name], thanks for getting in touch with [Business]. I'll have your quote ready within the hour. In the meantime, here's a quick look at what we do: [link]. Reply STOP to opt out."

Message 2 (day 2):

"Hi [Name], just following up on your enquiry. We've helped over 300 customers in [City] with exactly this. Happy to answer any questions, just reply here. [Business]"

Message 3 (day 4):

"A quick note from [Business]: we're running a 10 per cent discount for new customers this month. Want me to apply it to your quote? Reply YES and I'll update it now."

Message 4 (day 7):

"Hi [Name], last check-in from [Business]. Your quote is still valid. If you'd like to go ahead or have any questions, just reply or call [phone]. Happy to help."

Four touchpoints over a week, sent automatically, no manual effort after setup. You can extend the sequence or shorten it based on your sales cycle. For high-ticket services, a two-week sequence with six messages often works better. For low-cost products, two or three messages is enough.

Timing Your Sequence: When Messages Actually Get Read

The timing of each message matters as much as the content. Send at 11pm and you'll annoy people. Send mid-morning on a weekday and you'll catch most contacts when they're alert and checking their phone.

Under Australia's Spam Act 2003, commercial messages can only be sent between 9am and 8pm on weekdays and 9am to 5pm on weekends and public holidays. These aren't guidelines, they're legal requirements. Build these windows into your automation settings so messages never send outside permitted hours regardless of when the trigger fires.

Practical timing that works well:

• Day 1 welcome: send within five minutes of the trigger (leads cool fast)
• Day 2-3 follow-up: 10am or 11am Tuesday through Thursday
• Mid-sequence value message: midday Wednesday or Thursday
• Final follow-up: 10am Monday morning (fresh week, fresh decision-making)

Avoid Mondays for the first touch, Fridays for anything that requires a decision, and weekends unless your business is hospitality or retail where weekend context is natural.

Setting Up Automated SMS Sequences on Monster SMS

Monster SMS lets you build drip sequences directly in the platform without any coding. You set the trigger, write each message, define the delay between sends, and the sequence runs automatically for every contact that hits that trigger.

Here's the basic workflow:

1. Create a new campaign and select "Automated Sequence" as the campaign type
2. Set your trigger: form submission, contact tag, list import, or API event
3. Write each message in order, with the delay before each send (e.g. "send 2 days after previous message")
4. Add any personalisation tokens: [First Name], [Business Name], [Quote Link]
5. Set sending windows to enforce Spam Act hour restrictions
6. Activate and test with a personal number before going live

The AI auto-reply feature works well alongside drip sequences. When a lead replies to one of your automated messages, the AI can respond instantly and intelligently before handing off to you if the conversation needs a human. That way your leads never sit on read waiting for a response, even at 7pm when you've knocked off.

Monster SMS plans start at $50 per month for 1,000 messages, which covers most small businesses running two or three active sequences. The Starter plan is a reasonable entry point, and you can test everything on the free tier with 100 messages before committing.

Personalisation Without It Feeling Fake

Drip sequences can feel robotic if every message reads like a mail merge. The goal is automation that feels like a real conversation, not a system talking at someone.

A few things that help:

Use first name, sparingly. Starting every message with "[First Name]!" is what spam looks like. Use the name in the opening message and maybe one other, then write naturally from there.

Reference their specific enquiry. "Your quote for the kitchen renovation" reads better than "your enquiry". If you have the detail, use it.

Write short, direct messages. Long paragraphs in SMS are a red flag that you didn't write it yourself. Two to three sentences per message, max. Get to the point.

Give people a reply path. "Just reply here with any questions" converts better than a wall of information. SMS is two-way, use it. Two-way messaging means leads can respond and you can pick up the thread at the point where they're ready to talk.

If someone replies to your drip at any point and starts a conversation, your automation should pause or exit the sequence. Continuing to send automated messages while someone is actively talking to you looks disjointed and unprofessional. Monster SMS handles this automatically when two-way messaging is enabled.

Compliance for SMS Drip Campaigns in Australia

The Spam Act 2003 applies to every automated SMS campaign, no exceptions. The three things you must get right are consent, identification, and unsubscribe.

Consent: You need express consent before sending marketing messages. If someone fills in a contact form that says "I agree to receive SMS updates from [Business]", that covers it. Implied consent (they gave you their number for a quote) has limits and doesn't apply to marketing sequences. When in doubt, use a clear opt-in checkbox.

Identification: Every message must clearly identify who sent it. Using your business name or a registered sender ID covers this. Don't send from a random number with no identification in the body of the message.

Unsubscribe: Every commercial message must include a way to opt out. "Reply STOP to unsubscribe" at the end of your first message in a sequence is standard. When someone sends STOP, remove them immediately. Monster SMS handles this automatically.

For a detailed breakdown of what the law requires, read the Australian SMS compliance guide. Getting this right protects you from ACMA enforcement, which can issue fines for breaches.

What to Avoid

A few things that hurt more than they help:

• Sending too many messages too quickly: Three messages in 48 hours will get you blocked and a flurry of STOP replies. Space your sequence out over at least seven to fourteen days for a lead nurture flow.
• Generic messages that could come from anyone: "Just checking in!" with no context is not a follow-up, it's noise. Every message should reference something specific: their enquiry, your product, a relevant offer.
• No clear call to action: Every message needs one thing for the reader to do: reply, click, call, or book. Multiple options dilute response rates. Pick one and make it obvious.
• Sending outside permitted hours: Even if a trigger fires at midnight, your sequence should queue the message until the next permitted window. Set this in your automation rules, not just your calendar.
• Continuing sequences after someone replies: If a lead starts a conversation, the drip should pause. Sending automated messages to an active conversation makes your business look like it's run by a bot with no brain.
• Using purchased lists: Contacts from scraped or purchased lists have not consented to receive your messages. Sending to these lists is a Spam Act breach, and deliverability will be poor because the numbers are often inactive or incorrect.

Measuring Whether Your Drip Campaign Is Working

The metrics that matter for a drip sequence are different from a broadcast. You're not optimising for reach, you're optimising for progression through the funnel.

Track these:

• Reply rate per message: Which message in your sequence generates the most responses? That's your strongest touchpoint. Consider moving it earlier.
• Sequence exit rate: How many contacts make it through all messages without unsubscribing or replying? A high exit rate without conversion means the sequence isn't compelling enough to prompt action.
• Conversion rate by entry point: If you have multiple triggers (form fill vs paid ad vs referral), compare conversion rates by source. Some lead sources convert better through SMS than others.
• Opt-out rate: Above 2 per cent per message is a warning sign. It usually means messages are too frequent, too generic, or landing at the wrong time of day.

Monster SMS shows delivery, open, and reply data per campaign. Review your sequence performance monthly and adjust message timing or content based on what the data shows. Running SMS campaigns that actually convert takes iteration, and drip sequences give you clean, controlled data to learn from.
