Missouri specifics
How Missouri changes SMS retention marketing.
What we set up differently for a brand whose customers are in Missouri.
- SMS
Texting rules
Missouri no-call law RSMo 407.1095 to 407.1110
- Covers texts
- Yes. SMS and MMS were added in 2012.
- Consent
- Messages sent with the subscriber's prior express invitation or permission (a specific grant at a verifiable date and time), or to someone with a business contact in the last 180 days, are outside the law.
- Quiet hours
- None in the no-call law.
- Frequency
- No frequency cap.
- Registration
- No registration; the Attorney General sells the state list for scrubbing ($50 per area code per quarter).
- Private right of action
- Anyone who gets more than one violating message in 12 months can sue for up to $5,000 per knowing violation.
What we configure: Every Missouri opt-in is kept with a date and time; without one, or a purchase or contact in the last 180 days, promo texts are held back from numbers on the state list.

Missouri runs on Central Time
We schedule on Central Time for Missouri subscribers and on the subscriber's own zone for everyone else on the list, so quiet hours are kept wherever the customer lives.

Peaks: the holiday peak, back-to-school and summer tourism
Missouri runs 2 sales-tax holidays a year, and campaigns in those windows lead with the tax saving.
- Back-to-school sales tax holiday First Friday of August through Sunday (2026: Aug 7-9): Clothing $100 or less per item; school supplies up to $50 per purchase; computer software $350 or less; personal computers and peripherals $1,500…
- Show Me Green sales tax holiday April 19-25 each year: ENERGY STAR-certified new appliances, up to $1,500 per appliance
Who this is for
Signs your Missouri store needs this now.
Three of the patterns we see most in the audit.
All six signs- 01
Consent
You are not sure your opt-ins would hold up
A pre-ticked box or a single “enter your number” field is not consent. Get this wrong and every text after it is a liability, not a channel.
- 02
Frequency
Unsubscribes climb after every send
SMS churn is unforgiving. If opt-outs spike with each campaign, the channel is being used for messages that belonged in email.
- 03
Attribution
You cannot say what SMS earned last month
Attentive and Klaviyo both attribute revenue per message. If the number is not in a report, SMS is a cost with a hopeful story attached.
What is included
Everything the retainer covers, in the order we build it.
Six steps and about six weeks to live: audit, strategy, build, launch, test, report.
How we work- 01
Consent audit and capture rebuild
Where numbers are collected, what the customer saw, what was stored. Then a two-step opt-in at checkout and in the pop-up, with the disclosure text and records that satisfy the TCPA and state rules.
- 02
Compliance rules in the sending logic
Federal quiet hours (8 a.m.–9 p.m. in the recipient’s local time) and the tighter state windows applied by area code, frequency caps, STOP and HELP handling, and a documented policy your team can show a lawyer.
- 03
The four SMS moments, built
Restock alerts from the waitlist, short flash windows with VIPs first, delivery and shipping updates, and one time-critical win-back text. Each written to be read in three seconds.
- 04
Email and SMS orchestration
Every SMS step lives inside the lifecycle flows next to its email steps, with rules for who gets which channel, so nobody gets both saying the same thing.
- 05
Segmentation for SMS
Engaged, VIP, waitlist, lapsed — SMS lists are smaller and sharper than email lists. Most of your subscribers should receive a text rarely; a few should receive them first.
- 06
Two-way inbox handling
Replies routed to your support tool or handled by us with agreed scripts, so the questions your best customers ask by text get answered.
- 07
Attribution and monthly reporting
Revenue per message and per flow, opt-out rate per send, and SMS share of total revenue — next to email in one report, so the channels are judged together.
- 08
Platform setup or migration
Attentive when SMS is the primary channel; Klaviyo SMS when one platform for both is the better trade. Numbers, short codes, toll-free verification and carrier registration handled.

Questions
SMS retention marketing in Missouri: questions
What does Missouri law change about SMS marketing?
Missouri no-call law (RSMo 407.1095 to 407.1110) applies to marketing texts sent to Missouri numbers. Consent: Messages sent with the subscriber's prior express invitation or permission (a specific grant at a verifiable date and time), or to someone with a business contact in the last 180 days, are outside the law. Quiet hours: None in the no-call law. Frequency: No frequency cap. Every Missouri opt-in is kept with a date and time; without one, or a purchase or contact in the last 180 days, promo texts are held back from numbers on the state list.
What time should Missouri brands send marketing emails and texts?
Texts only inside the legal window in the subscriber's local time: None in the no-call law. For email we test send times per segment rather than guess, starting from mid-morning local time.
When are Missouri's biggest retail moments?
The holiday peak, back-to-school and summer tourism. The sales-tax holidays (Back-to-school sales tax holiday, First Friday of August through Sunday (2026: Aug 7-9); Show Me Green sales tax holiday, April 19-25 each year) get their own campaigns. BFCM runs 27-30 November 2026 everywhere.
How much does SMS retention marketing cost for a Missouri brand?
Tier 1 is $3,500 a month, for brands doing $500K–$2M a year. Tier 2 is $5,500 a month, for scaling brands at $2M+. Every engagement starts with a free 60-minute audit, and the price is the same in every state.
What is SMS retention marketing?
SMS retention marketing uses text messages to bring existing customers back: restock and back-in-stock alerts, flash and early-access windows, delivery updates and time-critical win-back. It works because texts are read within minutes, which is also why it has to be used sparingly: every message needs a reason to interrupt someone's phone.
Is SMS marketing legal in the US?
Yes, with the right consent. Under the TCPA a brand needs express written consent before sending marketing texts, a clear way to opt out by replying STOP, sending outside quiet hours (8am to 9pm in the recipient's time zone under federal rules, stricter in some states) and a registered sender. We set up consent capture and send rules before the first campaign, because violations carry statutory damages per message.
Is SMS still worth it for retention?
For the right moments, yes. Texts are read far faster than email, so SMS earns its keep on restocks, limited windows and delivery updates. It stops working when it becomes a second newsletter, because opt-outs climb quickly. We keep it to two to four messages a month to engaged subscribers and report its revenue next to email so the comparison is honest.
Attentive or Klaviyo SMS?
Attentive when SMS is your primary retention channel and you want its capture tools and two-way features; Klaviyo SMS when you are already on Klaviyo and want one profile, one segment set and one report. The audit makes the call against your list and catalogue.
