If you're shopping for Salesmessage, you probably want one thing: a shared inbox where a sales or support team can text customers like a group of humans, not a faceless 1-800 number. That's a real, specific need, and Salesmessage solves it well. But the people I talk to who outgrow it usually hit the same wall — they're paying a per-seat, inbox-shaped price for what's really just SMS underneath, and the moment they want to also dial those contacts, they're bolting on a second tool.
Full disclosure: I work for ReadySMS, so read this as an interested party who's trying very hard to be fair. I'll start with where Salesmessage genuinely earns its keep, then show where a leaner stack — cheap registered SMS, a built-in dialer, and 10DLC handled for you — makes more sense. Confirm any Salesmessage pricing or feature details at their site; this post avoids quoting their numbers because they change.
Where Salesmessage is genuinely strong
Let me be honest about what it does right, because pretending otherwise wastes your time.
- The shared-inbox UX is polished. Assigning conversations, internal notes, @mentions, and read/unread states across a team is the whole product, and it shows. If your team lives in the inbox all day, that polish matters.
- It's built for two-way, human conversations. This isn't a blast tool wearing an inbox costume. Reps actually have back-and-forth threads, and the interface respects that.
- Native CRM and integration breadth. HubSpot, Salesforce, and Zapier connections are mature. If your CRM is HubSpot, that integration alone might keep you there.
- Good for support-and-sales hybrid teams. When the same number handles inbound questions and outbound follow-up, a true shared inbox beats a bulk tool.
If that description fits you exactly and you never plan to call anyone, Salesmessage might be the right answer. No hard feelings. The rest of this is for people who want more send volume, want voice in the same place, or just don't want to pay inbox-suite pricing for texts.
The hidden cost: paying inbox pricing for raw SMS
Here's the structural thing. A shared-inbox product prices on seats and conversations because that's the value it sells. But the underlying SMS — the segment that hits the carrier — costs roughly the same for everyone. When you send a lot, the markup between "raw carrier cost" and "what the inbox tool charges" becomes the bulk of your bill.
ReadySMS is built the other way around: a thin, transparent layer over carrier infrastructure, priced per segment, plus a flat $0.0045/segment carrier pass-through that we itemize separately instead of hiding in the rate.
| Monthly outbound volume | ReadySMS per segment | + carrier pass-through | All-in |
|---|---|---|---|
| 0–50,000 (Starter) | $0.0155 | $0.0045 | $0.0200 |
| 50,000–500,000 (Growth) | $0.0125 | $0.0045 | $0.0170 |
| 500,000+ (Enterprise) | $0.0028 | $0.0045 | $0.0073 |
So an outbound SMS on the Growth tier lands around $0.017 all-in — under two cents a text, registered. You can run your own numbers on the cost calculator.
A worked example
Say a 6-person team sends 40,000 outbound segments a month — a mix of follow-ups and a few campaigns. On ReadySMS Starter that's:
40,000 × ($0.0155 + $0.0045) = $800/month in messaging.
No per-seat tax on top of that. With most inbox tools, you're paying a monthly platform fee per seat and a message rate. Six seats adds up fast before a single text goes out. The exact gap depends on Salesmessage's current plan — check their pricing page — but the shape is consistent: the more you send, the more the inbox markup costs you.
If trimming spend is the main reason you're here, how to actually reduce SMS costs goes deeper on segment math.
Segment math is where bills quietly inflate
This trips up everyone, regardless of platform. One SMS segment is 160 GSM-7 characters. Go over that and the message splits into 153-character multipart segments. Drop a single emoji or curly quote and you switch to unicode, which cuts the limit to 70 characters (67 per part after that).
Worked example: a 175-character promo with one 🎉 in it becomes 3 unicode segments. Blast that to 5,000 contacts on the Starter tier:
5,000 × 3 × ($0.0155 + $0.0045) = $300 for one send.
Strip the emoji and tighten copy to 160 plain characters and the same blast is one segment per contact:
5,000 × 1 × ($0.0155 + $0.0045) = $100.
Same audience, same offer, one-third the cost. This math is identical no matter which platform you use — the difference is whether your tool shows you the segment count before you hit send. ReadySMS does, and the cheap per-segment rate means a mistake here stings less.
Where ReadySMS pulls ahead
1. A power dialer in the same tool
This is the big one for sales teams. With Salesmessage you text; to call, you add a separate dialer and a separate bill. ReadySMS includes an outbound Power Dialer — manual and queue dial, call recording, voicemail drop, transfer/barge/whisper, and speed-to-lead auto-dial on new leads.
Dialer plans, billed per agent, minutes in 6-second increments:
- Free — $0/mo, 1 agent, 500 minutes included, then $0.06/min
- Pro — $29/agent/mo, up to 3 agents, $0.05/min
- Team — $69/agent/mo, unlimited agents, $0.0375/min, speed-to-lead, lead routing, manager monitoring
The combination is the point: a new lead comes in, ReadySMS fires an instant text and drops the rep an auto-dial inside the first five minutes — when contact rates are dramatically higher. Two tools used to do that. Now it's one. If voice is your priority, the OpenPhone alternative and PhoneBurner alternative write-ups cover that angle too.
2. Native GoHighLevel integration
If you run on GoHighLevel — or you're an agency managing client sub-accounts — this is decisive. ReadySMS connects via OAuth with two-way sync of inbound and outbound messages, mapped per location/sub-account so each client stays isolated. Inbound replies land in the conversations inbox and in GHL. Salesmessage isn't built around GHL; if that's your CRM, the native path matters. The GHL SMS setup guide walks through it.
3. 10DLC done for you
US A2P texting requires 10DLC registration, or carriers filter your traffic. ReadySMS handles brand + campaign registration in-app — roughly ~$10/mo per brand and ~$20/mo per campaign in carrier fees, approval usually 4–7 business days. If you're fuzzy on why this is non-negotiable, here's the plain-English 10DLC explainer.
4. Compliance built in, not bolted on
- Automatic STOP handling — opt-outs are honored and propagate so that contact can't be messaged again across campaigns.
- Quiet-hours enforcement — sends are held outside permitted local hours, based on the recipient's area.
- Litigator / DNC scrubbing — a standalone TCPA & DNC Litigator Scrub at $0.005 per contact checks each number against known litigator and DNC-complainer lists and suppresses matches before send.
That last one is cheap insurance. TCPA exposure runs $500–$1,500 per text; scrubbing 5,000 contacts costs $25. None of this makes you lawsuit-proof — compliance is ultimately the sender's responsibility — but it removes the easy mistakes.
5. Test free, then get $25 to start
You can try ReadySMS with 20 free test sends to your own verified number, and you get a $25 credit when you submit 10DLC registration. Prove the tool works before you spend anything on real campaigns — no monthly platform fee, pay-as-you-go.
When to stay with Salesmessage
I'd rather you pick right than pick us. Stay with Salesmessage if:
- Your team genuinely lives in a polished shared inbox all day and that workflow is the product you're buying.
- You're deep in HubSpot or Salesforce and their native sync is doing real work.
- Your send volume is low and conversational, where per-message savings don't add up to much.
- You don't need outbound calling at all.
Switch to ReadySMS if you want cheaper registered SMS, voice and text in one tool, native GoHighLevel, 10DLC handled for you, and a bill you can actually read line by line.
The practical takeaway
Salesmessage sells a shared inbox, and prices like one. That's fair when the inbox is your job. But if you're mostly buying SMS — and especially if you also want to dial those contacts — you end up paying inbox-suite rates for carrier-cost texts, then stapling a separate dialer on top.
ReadySMS unbundles that: ~2¢ all-in registered segments (less at volume), a power dialer in the same place, GHL-native sync, and 10DLC done for you. Run your list through the calculator, or take the 20 free test sends — and the $25 credit when you register — and send a real campaign. Worst case, you confirm Salesmessage was right for you — and now you know why.
