SMS blast marketing: how it works and how to set it up

SMS blast marketing, sending one text to a whole segment at once, is the right tool far less often than most firms use it. A blast suits news that is equally relevant to everyone on a list at the same moment. For almost everything else, a triggered message that goes out when a specific person does something performs better and annoys fewer people. This article answers when to choose a blast over automation, how often you can blast before your list wears out, and how to set one up on the levelpartner.ai platform when it is the right call.

Blast or trigger: the deciding question

Ask: would this message be just as relevant to every recipient if it arrived today? If yes, a blast fits. If relevance depends on where each person is in their journey, use a trigger.

Good blast subjects: an office move, a change in opening hours, a public event with limited places, a new regulation affecting all clients. Poor blast subjects: a follow-up after an enquiry, a renewal reminder, a nudge after a quote. Those depend on timing that differs for each person, and our guide to automated text marketing covers them.

How often is too often

There is no universal rule, but there is a reliable signal: opt-outs per send. Track it for every blast. When it starts rising over three consecutive sends, you are blasting too often or to too wide a list.

For most professional service firms, one blast a month is a sensible ceiling, and many do better with one a quarter. Agencies and real estate firms with frequent news can sometimes go higher for specific segments, such as active buyers, but only with tight lists.

Illustration: a 50-person agency reviewing its blast frequency

Say the agency blasts its 4,000 consented contacts weekly and loses about 30 to opt-outs per send: roughly 1,500 contacts a year. Suppose it switches to a monthly blast to its most engaged 1,500 and moves follow-ups into triggered workflows. If opt-outs fell to about 6 a send, the annual loss would drop to around 70 while replies could hold steady. The inputs are illustrative.

Before you start

  • A message that passes the "relevant to everyone today" test.
  • A consented smart list, filtered by recent engagement where possible.
  • A record of past blasts with dates and opt-out counts.
  • Someone ready to handle replies.

How to set it up

Check your blast record first: if this list had a blast within your agreed interval, wait. Then send from Contacts.

  1. Go to Contacts.
  2. Select the contacts you want to message, using the segment's smart list.
  3. Choose the Send SMS Bulk Action.
  4. Select the sending phone number when required.
  5. Enter your SMS message or insert a snippet.
  6. Review the recipients and message.
  7. Choose Send immediately, Schedule for later or Use Drip Mode.
  8. Configure any additional delivery settings.
  9. Review the campaign before confirming the send.

After the send, add the date and audience to your blast record, and two days later note the replies and opt-outs from the send\'s stats in Bulk Actions.

Turning a blast into a conversation

The best blasts ask for a reply rather than a click. "Reply YES for a place" produces a list of interested people your team can follow up personally. Set a workflow to tag those replies and create tasks, so the blast feeds your pipeline instead of ending with the send.

What blasts replace and what they cost

In a 10 to 250 person firm, a blast replaces ringing round or an email that sits unread. It takes under an hour to prepare and send. The hidden cost is list attrition: every unnecessary blast removes some contacts permanently. Treat your consented list as an asset you spend carefully.

The mistake most people make

Using blasts as a substitute for automation. A firm that blasts "just checking in" to every open lead each week is doing a trigger's job badly. Build the follow-up workflow once and the blast becomes unnecessary.

The common mistake

Blasting dormant contacts to "wake them up". People who have not heard from you in two years are the most likely to report the text. Re-engage them by email first.

When not to blast

Not for anything personal, anything with a deadline that differs per person, or anything only a small group needs. Not to contacts without clear consent. And not when you have nothing new to say. For high-volume sends with pacing and registration concerns, read mass SMS marketing; for a broader view, see bulk text marketing.

Troubleshooting

Opt-outs spike after a blast. The list was too broad or the message too promotional. Narrow the smart list to recent engagement.

Replies arrive but no one follows up. Add a workflow that tags replies and assigns a follow-up task.

The same people get blasts from two teams. Keep one shared blast log and agree an owner for each list.

Delivery failures are high. The list includes old or invalid numbers. Clean them out before the next send.

Frequently asked questions

Is an SMS blast the same as bulk SMS?

Mostly. A blast usually means a single send at one moment. Bulk SMS can also cover large sends spread over time.

What is the best day to send a blast?

Midweek mornings work for most business audiences. Test against your own replies rather than following a fixed rule.

No. SMS needs its own consent. Invite them to opt in to texts by email first.

No. A reply request often works better for service firms and looks less like spam.
