Why Renewal Outreach Runs on SMS in the First Place
Our companion guide on renewal and nurture pipelines covers building the outreach cadence itself. This guide is about the platform layer underneath it: what SMS costs at renewal-campaign volume, and what has to be true about that setup before a single message goes out, given how exposed this industry is to TCPA litigation.
SMS reaches a merchant who may not answer a cold call but will glance at a text, a real advantage for renewal outreach specifically, since a past-client relationship already exists and a short message can restart that conversation without the friction of an unscheduled call.
What SMS Costs
Twilio’s own published US pricing lists outbound and inbound SMS segments at $0.0083 each, with outbound MMS at $0.022. A Twilio-leased local number runs $1.15 monthly, or $0.50 monthly to bring an existing number over, and a toll-free number runs $2.15 monthly. Carrier fees add roughly $0.0025 to $0.007 per message depending on the destination carrier, and a failed-message processing fee of $0.001 applies to sends that do not go through.
At renewal-campaign scale, those per-message costs are small individually but add up directly with the size of a shop’s renewal book, worth modeling against actual campaign volume rather than treated as a rounding error.
The Compliance Layer That Isn’t Optional
A2P 10DLC, application-to-person 10-digit long code registration, is a required brand and campaign registration layer for business SMS in the US, separate from the base per-message pricing above. HighLevel’s own support documentation states that brand registration, campaign registration, monthly campaign fees, and carrier per-message charges are passed through to the sender with no platform markup, though the exact current fee schedule needs pulling directly from the platform in use rather than assumed from a general figure here.
Skipping or delaying this registration is not a cost-saving move. It is the step that keeps outbound SMS from getting flagged, filtered, or blocked by carriers before it ever reaches a merchant.
Why “TCPA-Safe” Is the Operative Phrase, Not Decoration
TCPA class-action filings hit 507 in the first quarter of 2025 alone, up 112% year over year, and by September 2025 that number reached 2,128 filings year to date, with September alone accounting for 224 filings, a 283% spike over the same month a year earlier. Roughly 80% of all TCPA lawsuits filed today are class actions, and the average class settlement exceeds $6.6 million.
SMS carries the exact same consent rules as a phone call under TCPA, not a lighter version of them. A renewal SMS sent to a merchant without proper documented consent carries the same legal exposure as an undocumented cold call, which is the reason platform setup matters as much as message content here.
What a Compliant Setup Requires
Our companion guide on TCPA for MCA shops covers documented consent in full depth, what documented consent should mean, beyond what the law requires on paper. At the platform level, that means a renewal SMS program needs a clear opt-in trail for every number being texted, a working opt-out mechanism honored immediately, and A2P 10DLC registration completed before volume ramps up, not treated as paperwork to finish later.
None of that is a one-time setup task. It is an ongoing discipline a shop has to maintain as its renewal list grows and changes.
Choosing a Platform Against This Bar
The right SMS platform for renewal outreach is the one that makes A2P 10DLC registration, opt-out handling, and consent documentation straightforward parts of the workflow, not optional add-ons a shop has to build separately. Raw per-message cost matters, but it is a smaller factor than whether the platform keeps a shop inside the consent rules this section documents, given what a single TCPA class action can cost.
Human + AI SDRs run every merchant conversation, including renewal outreach, through a documented consent and compliance process by default, so a shop is not building that discipline separately on top of whatever SMS tool it licenses.
What this means for you
- Twilio prices SMS at $0.0083 per segment, with numbers running $1.15 to $2.15 monthly, plus a separate, required A2P 10DLC brand and campaign registration layer.
- TCPA class-action filings hit 507 in Q1 2025 alone, up 112% year over year, with the average class settlement exceeding $6.6 million, real exposure SMS carries under the same consent rules as a phone call.
- The right SMS platform for renewal outreach is judged less on raw per-message cost and more on how straightforward it makes consent documentation and A2P 10DLC registration.
