Salesmsg vs ReadySMS for GoHighLevel Teams
If you run sales or support inside GoHighLevel and you've outgrown LC Phone, the shortlist usually comes down to a few names. Salesmsg is one of the strongest — a clean two-way texting product with a real inbox, a dialer, and a Zapier-friendly approach to connecting tools. ReadySMS is the other side of the comparison: a thin, transparent layer over carrier infrastructure that installs into GHL natively over OAuth.
Full disclosure: I work for ReadySMS. So I'll be specific about where we win and honest about where Salesmsg is genuinely a good fit — because that's more useful to you than a sales pitch dressed up as a comparison.
The short version: both do two-way SMS well. The differences that matter for a GHL team are how the integration is wired, whether the inbox is unified inside the CRM, what the dialer costs, and — the part nobody likes to model — how the per-message economics behave once you're sending real volume.
How the GHL integration actually works
This is the first fork in the road, and it's bigger than it sounds.
Salesmsg connects to GoHighLevel, but the integration is built around syncing contacts and triggering messages — typically through native connectors and middleware like Zapier or Make. It works. But you're often managing two sources of truth: the Salesmsg inbox where conversations live, and the GHL contact record where everything else lives. For a single user that's tolerable. For a team handing off leads, it's a recurring "wait, where did that reply go?" problem.
ReadySMS installs into GHL natively over OAuth, mapped per location / sub-account. Inbound and outbound sync two ways, so a reply that lands in ReadySMS also lands in the GHL conversation thread, attributed to the right contact, inside the workflow you already built. For agencies, the per-location mapping means each client stays isolated — no cross-contamination of numbers or conversations.
If you've never wired up a GHL number layer before, the GHL SMS setup guide walks through the OAuth install step by step.
The practical takeaway: if your team lives in GHL all day, a native two-way sync removes an entire category of "which screen is the truth" friction. If your team lives in a standalone texting app and only occasionally touches the CRM, that advantage shrinks.
The unified inbox question
Both products give you a conversations inbox. The difference is where it is.
- Salesmsg gives you a polished standalone inbox. Good UX, easy to teach a rep. But it's a separate surface from GHL.
- ReadySMS puts inbound replies in its own in-app inbox and in the connected GHL conversation thread. Your reps can work where they already work.
For a two-person shop, a standalone inbox is fine — maybe even cleaner. For a team where leads route between SDRs, account managers, and a closer, having the conversation attached to the GHL record (with the deal stage, the notes, the form submissions) is the thing that prevents dropped balls. The inbox isn't just where you read texts; it's where context lives.
Voice: the power dialer most comparisons skip
Salesmsg added calling, and it's reasonable. But if voice is a real part of your motion — speed-to-lead, follow-up calling, an outbound team — the dialer details and cost structure matter as much as the texting.
ReadySMS bundles a Power Dialer as a first-class product, billed per agent, with minutes metered in 6-second increments:
| Plan | Price | Agents | Per minute | Notable |
|---|---|---|---|---|
| Free | $0/mo | 1 | $0.06 (500 min included) | 1 free number |
| Pro | $29/agent/mo | up to 3 | $0.05 | call recording, voicemail drop |
| Team | $69/agent/mo | unlimited | $0.0375 | speed-to-lead auto-dial, lead routing, transfer/barge/whisper, manager monitoring |
The feature that earns its keep is speed-to-lead on the Team plan: a new lead hits your form, ReadySMS fires an instant SMS and auto-dials an available agent. The first-five-minutes advantage is real — contact rates fall off a cliff after that window — and pairing an instant text with an auto-dial is the cleanest way to win it.
A quick cost-per-connect sketch: if a rep makes 200 dials a day at an average 90 seconds of talk time on connects, you're looking at maybe 30–45 connected minutes a day. On the Team plan that's roughly $1.10–$1.70/day in voice minutes per agent on top of the $69/seat. Model it against your own connect rate on the pricing page before you commit.
AI-assisted replies
Both ecosystems are adding AI. ReadySMS includes optional AI-assisted replies for inbound conversations with three modes — off, suggest, and auto. "Suggest" is the sane default: it drafts a reply a human approves before it sends. "Auto" is for narrow, well-defined flows (confirm an appointment, answer a hours question) where you trust the guardrails.
I'll keep this honest: AI reply quality across every platform depends entirely on how tightly you scope it. Don't pick a vendor on the AI checkbox alone — it's a newer capability everywhere, and the gap between "demo magic" and "reliable in production" is wide. Treat it as a nice-to-have, not the deciding factor.
The cost structure difference at volume
Here's where the two diverge most, and it's structural, not cosmetic.
Many SMS apps — Salesmsg included — price on a credit-bundle or per-message retail model with the carrier fees folded into the number. That's clean and predictable at low volume. It's also where the markup hides: the closer you look, the more of your per-message cost is margin you can't see.
ReadySMS prices as a transparent layer over carrier infrastructure. You pay a per-segment rate that drops by tier, plus a flat $0.0045/segment carrier pass-through billed separately and unmarked-up:
| Tier | Volume / month | Per segment |
|---|---|---|
| Starter | 0–10,000 | $0.0084 |
| Basic | 10,001–50,000 | $0.0074 |
| Standard | 50,001–250,000 | $0.0064 |
| Pro | 250,001–1,000,000 | $0.0049 |
| Enterprise | 1,000,000+ | as low as $0.0028 |
I won't quote a competitor's per-message number — that's a fast way to publish something that's wrong by next quarter. But the qualitative reality is consistent: a transparent carrier-passthrough model gets cheaper than a bundled-retail model as your volume climbs, and the gap widens at scale.
Worked example. Say a 5-rep team plus automations sends 60,000 SMS segments a month. On ReadySMS that's the Standard tier:
`` 60,000 × ($0.0064 + $0.0045) = 60,000 × $0.0109 = $654/mo ``
The same volume on a bundled-retail model where each message carries hidden margin can run meaningfully higher per message — and you don't get to see the line item that explains why. The point isn't the exact dollar gap; it's that one model shows you the carrier cost and one buries it. Run your own numbers on the cost calculator.

Compliance and 10DLC
If you're sending business SMS in the US, A2P 10DLC isn't optional — unregistered traffic gets carrier-filtered, and you'll watch your delivery rate quietly collapse.
Both platforms support registration. ReadySMS handles the full 10DLC flow in-app: brand + campaign registration (roughly ~$10/mo per brand and ~$20/mo per campaign in carrier fees, approval usually 1–3 days), plus the operational stack that keeps you out of trouble:
- Automatic STOP / opt-out handling that propagates across campaigns so an opted-out contact stays opted out everywhere
- Quiet-hours enforcement that holds sends outside permitted local hours
- Litigator / DNC scrubbing to screen known TCPA-litigator and DNC numbers before send
- Consent / attestation capture for an audit trail on bulk and API sends
None of this makes you lawsuit-proof — compliance is ultimately the sender's responsibility — but it removes the most common ways teams get themselves filtered or sued. The standalone TCPA & DNC litigator scrub runs $0.005/contact, which is cheap insurance against $500–$1,500-per-text TCPA exposure.
If 10DLC approval is the part stressing you out, what actually gets approved is worth a read before you submit.
So which one fits your team?
Honest decision guide:
- Choose Salesmsg if your texting motion is mostly standalone, your team prefers a dedicated inbox app over the CRM, your volume is modest enough that bundled pricing stays cheap, and the deepest GHL sync isn't a priority.
- Choose ReadySMS if your team lives inside GoHighLevel, you want inbound/outbound conversations attached to GHL records natively, you run (or plan to run) outbound voice through a power dialer, and your monthly volume is high enough that transparent per-segment pricing beats a retail bundle.
For agencies specifically — where rebilling margin is the whole point — the unified inbox plus per-location isolation plus transparent wholesale pricing is the combination that compounds. The agency buyer's guide for GHL SMS providers lays out the full criteria if you're shortlisting.
You can start with 2,500 free credits, no card required, install the native GHL integration, and send a real campaign before deciding anything. The cleanest test is the one that uses your actual numbers — so send a few thousand messages, watch where the replies land, and check the line items on the bill.
