Leads usually don’t reply to follow-up texts for one of five reasons, and wording is the last of them: the text never arrived, arrived late, didn’t say who sent it, asked nothing easy, or the follow-up stopped too soon. Check delivery first: if more than 5% of sends fail (a rule of thumb, not a benchmark), fix that before rewriting.
The short answer from LeadsNow AI: Leads stop replying to follow-up texts when the message is undelivered, late, anonymous, hard to answer or never followed up, so test those five causes in that order before rewriting any copy. LeadsNow AI has booked 50,769+ sales appointments since 2017 with AI calling, SMS and DM follow-up.

- Who this is for: operators whose ads or forms produce leads (clinics, trades and home-services firms, coaches and consultants) and whose text follow-up gets silence.
- The diagnostic: the No-Reply Ladder, five causes in the order you test them. Each test rules out the cause above the next one.
- Rung 1 is delivery: Twilio blocks US texts from unregistered 10DLC numbers (error 30034). In Australia, an unregistered branded sender ID now shows as ‘Unverified’.
- Why unknown texts get ignored: people reported US$470 million in losses to the FTC from scams that started with a text in 2024, more than five times the 2020 figure (FTC).
- The number to measure: reply rate = unique leads who replied (not counting opt-outs) ÷ leads with at least one delivered text.
- Benchmarks: no public benchmark for SMS reply rate on a lead denominator exists. Compare cohorts of your own leads instead.
Why are my leads not replying to my texts? The No-Reply Ladder
The No-Reply Ladder is a five-rung diagnostic for follow-up texts that get no replies. The rungs are ordered so that each test rules out the next. An undelivered text can’t be too late, and a late text can’t be judged on its wording. Climb the ladder from rung 1 and stop at the first rung that fails.
| Rung | Cause | Symptom you see | Test that confirms it | Fix |
|---|---|---|---|---|
| 1 | Not delivered | Silence from every source and campaign at once | Delivery receipts: failed and undelivered as a share of sends, grouped by error code | Register the number or sender ID. Validate numbers on the form |
| 2 | Too late | Daytime leads reply; evening and weekend leads don’t | Median minutes from form submission to first text, split by hour of day | Automate the first text and cover replies outside office hours |
| 3 | Unknown sender | More opt-outs than replies on the first message | Hide the signature and read the text cold. Could anyone have sent it? | Give your name, the business and what they asked for in the first line. No link |
| 4 | No easy question | Leads click or read but never answer | Count the questions. Can it be answered in under five seconds? | End on one closed question |
| 5 | Stopped too soon | The sequence ends after one or two texts | Replies by message number in the sequence | Five or six texts with a new angle each time, then a closing text |
How it works
Diagnosing follow-up texts that get no reply
Check delivery receipts
Group failed and undelivered sends by error code before reading the copy.
Measure time to text
Compare median minutes from form to first text for repliers and non-repliers, by hour of day.
Read the text cold
Hide the signature: the first line must say who you are, the business and what was asked.
Count replies by message
Plot replies by message number; extend to five or six texts with a new angle each time.

How do you measure SMS reply rate properly?
SMS reply rate is the number of unique leads who sent any reply other than an opt-out, divided by the number of leads with at least one delivered text. Group leads by the week they arrived. Three counting mistakes make a funnel look worse or better than it is: counting messages instead of leads, counting STOP as a reply, and including leads whose texts were never delivered.
No public benchmark measures SMS reply rate on this denominator, so the thresholds below are triage rules of thumb used on this page, not industry figures. They tell you which rung to test, not what a good result is.
| Measure | Rule-of-thumb trigger | Go to |
|---|---|---|
| Failed or undelivered sends | Above 5% of sends | Rung 1 |
| Leads with an invalid or landline number | Above 10% of form leads | Rung 1 (the form) |
| Median time from form to first text | Over 5 minutes, or over 60 minutes after hours | Rung 2 |
| Opt-outs on the first message | More opt-outs than replies | Rung 3 |
| Replies arriving after message 2 | Unknown, because the sequence stops at 2 | Rung 5 |

Are my follow-up texts actually being delivered?
Undelivered texts are the most expensive kind of silence, because they look exactly like leads who ignored you. Open the delivery report in your SMS platform before you open the copy. In the US, Twilio’s error 30034 means the message came from a 10DLC number not attached to an approved A2P 10DLC campaign, and Twilio blocks those messages. Error 30007 means a carrier or Twilio filtered the message, for example as spam or phishing. Registration itself is covered in our A2P 10DLC registration guide.
In Australia, the ACMA’s guidance on sending texts with your business name says branded sender IDs had to be registered by 1 July 2026. Unregistered ones are labelled ‘Unverified’ and grouped on the phone with other unverified messages, scams included. If you send from an ordinary phone number, the ACMA says you don’t need to do anything. The detail is in our page on SMS sender ID registration in Australia.
The quieter cause is bad numbers. A landline typed into a mobile field can’t receive a text, and some form leads type a fake number on purpose. A line-type lookup at form submission catches both.
Did the follow-up text arrive while the lead still cared?
A follow-up text that arrives hours after the enquiry often reaches a lead who has already spoken to a competitor or lost interest. To test this rung, export form submission times and first-text times and compare the median gap for leads who replied with the median for leads who didn’t. Then split both by hour of day. If the 9pm and Saturday leads are the silent ones, the problem is coverage, not copy. Our page on why speed-to-lead conversion rates stay low covers where the minutes usually go.
Automating the first text fixes half of this. The other half is replying to the reply, because a lead who answers at 9:40pm and hears nothing until 10am is back to rung 2.

Does my first text look like it could be a scam?
A first text from an unknown number, with no business name and a link, follows the same pattern as the most-reported scam texts. The FTC’s Data Spotlight on the top text scams of 2024 reports US$470 million in losses to scams that started with a text, more than five times the 2020 figure. Fake package-delivery messages with a link to a lookalike website were the most reported. People who have learned to ignore that pattern will ignore yours too.
The test is simple. Cover the sender line and read the message as a stranger would. If it doesn’t say who you are, which business you are from and what the lead asked for, it fails. Fix all three in the first line and send the link later, once the lead has replied.
Does my text ask one question the lead can answer in five seconds?
A follow-up text that asks nothing gets nothing back. One that asks for a scheduling decision feels like work. The text that earns a reply ends on a single closed question with an obvious answer.
| Business | Text that gets silence | Rewrite that asks one easy question |
|---|---|---|
| Physio clinic | Thanks for your enquiry! Let us know if you have any questions. | Hi Sam, this is Jo at [clinic]. You asked about your knee. Is it from an injury, or has it built up over time? |
| Solar installer | Following up on your quote request. When’s a good time to chat? | Hi Priya, Ben at [business] about your solar quote. Do you own the roof, or are you renting? |
| Business consultant | Here’s my calendar link, book whenever suits: [link] | Hi Marco, [name] and team here. Is this for your own business or one you manage? |
Did my follow-up stop after one or two texts?
A follow-up sequence that stops after two texts can’t tell you whether texts three to six would have been answered. Plot replies by message number in the sequence. If nothing exists past message two, the test hasn’t been run. When you extend the sequence, give each message a new angle rather than another “just following up”: a useful fact, a different question, an easy way out (“Should I close this off for now?”). Stop immediately when someone opts out, in any wording.
Leads who went quiet months ago are a different job. That is database reactivation, not follow-up. LeadsNow’s Colliers-era reactivation campaigns averaged 4.4% and peaked at 8.9%. No window or sample is disclosed for those figures, and they are our own record, not an industry benchmark. Our database reactivation service covers that work.
When should you hand SMS follow-up to someone else?
Hand SMS follow-up to a done-for-you service when your ladder fails at rung 2 or rung 5. When delivery, sender identity and the question are fine, but leads go cold because nobody replies at night or nobody sends text four, the problem is staffing and persistence, not knowledge. A pay-per-result service carries that cost.
Fix it yourself if the ladder fails at rung 1, 3 or 4. Submitting a registration, validating phone fields and rewriting a first text take an afternoon between them (carrier review then runs on its own clock), so don’t hire anyone to do them.

Frequently asked questions
What is a good reply rate for follow-up texts?
There is no public benchmark for SMS reply rate on a lead denominator, and figures quoted without a stated denominator can’t be compared with yours. Measure unique non-opt-out replies divided by leads with a delivered text, by weekly cohort, and compare each change against your own previous cohorts.
Why do my texts show as delivered but nobody replies?
If delivery is fine, test the next three rungs in order: how many minutes passed before the first text, whether the first line names you and what the lead asked for, and whether the text ends on one question the lead can answer in five seconds.
Should a follow-up text include opt-out wording?
Follow your country’s rules and your carrier’s requirements, which is not something to decide on reply rates. In the US, the CTIA Messaging Principles and Best Practices say senders should state in the message how to opt out. This is general information, not legal advice.
Do links in a text stop leads replying?
A link in a first text from an unknown sender matches the pattern of the most-reported scam texts. The FTC lists fake package-delivery messages with lookalike links as the top text scam of 2024. Earn the reply first, then send the link.
