If you're sending business SMS through Twilio in 2026, you're paying for a brand name your CTO recognized in 2015. The carrier delivery is identical. The infrastructure underneath is identical. The only thing that changes when you move to ReadySMS is your bill — meaningfully lower at volume, up to ~40% at enterprise scale — and the work your team has to do, which goes down, not up.
This post lays out the honest math.
What Twilio actually costs you
Twilio's published rate is $0.0079/segment. The number that lands on your invoice is $0.0170-$0.0124/segment once carrier surcharges are added (~$0.003-$0.0045/msg, pass-through from T-Mobile, AT&T, and Verizon).
At 100,000 messages/month that's a $1,090-$1,240 line item. At 500,000/month it's $5,450-$6,200. At 1M/month, $10,900-$12,400. And those are only the per-message costs — they don't include 10DLC fees ($1.50 markup over TCR pass-through), phone number rentals ($1.15/number/mo), or the engineering hours your team burns building campaign management, opt-out tracking, and inbound webhook handling on top of Twilio's raw API.
What ReadySMS costs
ReadySMS bills the same way — per segment, plus the same carrier fee. The difference is the per-segment number.
| Tier | Per-segment | Carrier fee | All-in / msg |
|---|---|---|---|
| ReadySMS Starter (0–50K/mo) | $0.0155 | $0.0045 | $0.0200 |
| ReadySMS Growth (50K–500K/mo) | $0.0125 | $0.0045 | $0.0170 |
| ReadySMS Enterprise (500K+/mo) | $0.0028 | $0.0045 | $0.0073 |
| Twilio retail | $0.0079 | $0.003-$0.0045 | $0.0170-$0.0124 |
At Starter and Growth volumes, ReadySMS's per-message cost is in the same range as Twilio's all-in rate — the savings there come from the platform you don't have to build (below). At Enterprise volume (500K+/mo), ReadySMS lands at $0.0073 all-in — roughly 40% below Twilio's best-case invoice rate.
What you stop paying engineers to build
The per-segment delta is the easy money. The bigger savings come from the work ReadySMS ships and Twilio doesn't:
- Campaign manager — schedule blasts, segment contacts, A/B test first messages. Building this on raw Twilio is a 2-4 week engineering project plus ongoing maintenance.
- Two-way conversations inbox — shared team inbox with assignment, tags, threading. Twilio gives you the API; you build the UI.
- 10DLC dashboard — brand and campaign registration with status tracking and resubmission flows. Twilio's portal is functional but bare; ReadySMS walks you through it and handles rejections.
- Opt-out tracking — STOP/UNSUBSCRIBE handling, suppression list, audit log. On Twilio you write this yourself and you carry the TCPA risk if you get it wrong.
- GoHighLevel marketplace install — one-click integration that drops ReadySMS into the GHL UI. There is no equivalent for Twilio; agencies pay developers to glue them together.
- Drip sequences and recurring messages — scheduled message processors that survive restarts and handle timezone arithmetic. You build all of this on Twilio.
A typical SaaS team building "SMS as a feature" on top of Twilio sinks 3-6 weeks of engineering time before the first production send. That's $25,000-$50,000 in labor before the first message goes out — and ongoing maintenance forever after. ReadySMS ships all of it on day one.
The migration is shorter than you think
Most teams overestimate the cost of switching off Twilio. The pattern that works:
- Pick a low-volume sub-account or product line first. Move 5-10% of your traffic to ReadySMS for two weeks while keeping Twilio active.
- Re-register 10DLC on ReadySMS. Not a transfer — new brand and campaign registration through ReadySMS's dashboard. 1-3 days for TCR, another 5-8 days for carrier review. ReadySMS's support team handles rejections.
- Port your numbers (LNP) gradually. 1-2 numbers at a time. Each port takes 7-14 business days. Don't move your highest-volume number first.
- Keep Twilio active for 60 days post-migration. You will find a forgotten cron job sending through the old account. Better to find it on a $50 invoice than at customer-support-ticket time.
Total elapsed time for a typical migration: 2-4 weeks, with ReadySMS doing most of the 10DLC work. Engineering effort on your end: a few hours to repoint your API endpoints.
The agency math (for GoHighLevel users specifically)
If you're a GHL agency paying LC Phone $0.0158/segment ($0.0203 all-in), the math is even more lopsided (we broke down the full LC Phone bill line by line if you want the receipts). A 20-sub-account agency sending 60,000 msgs/month total spends:
- LC Phone: $1,218/month → $14,616/year
- ReadySMS Growth ($0.0170 all-in): $1,020/month → $12,240/year
- Annual savings: $2,376 at this volume; the gap widens sharply past 500K msgs/month, where ReadySMS drops to $0.0073 all-in.
The integration is a one-click marketplace install. Your clients see no change in UI; you keep the same workflows. The bill drops by ~16% the first month at this volume — far more at scale.
Why ReadySMS exists
ReadySMS was built specifically because Twilio is too expensive for the use case it's most often pointed at — SMS marketing and customer engagement at small-to-mid volumes — and because LeadConnector (GHL's default) is a Twilio wrapper sold at 2x markup with zero added value. (I wrote up the origin story of the wrapper separately if you want the founder context.) Both leave money on the table that goes straight to ReadySMS customers' margin instead.
The product layer is where the real moat is: a campaign manager you'd pay $20K to build on Twilio, ships in a $10/month subscription. A GHL marketplace install that took ReadySMS three months to engineer, you install in two minutes. A 10DLC support team that knows the exact rejection patterns to fix, included.
If you're sending serious volume on Twilio and also paying engineers to maintain the tooling around it, you are overpaying. If you're on LC Phone, you're overpaying by a lot. The migration is shorter than the next quarter's invoice cycle.
