Heymarket Alternative: SMS, Dialer & 10DLC in One — ReadySMS
If you're shopping for a shared team SMS inbox, Heymarket has probably come up. It's a well-built product aimed squarely at support and sales teams who want shared conversations, assignment, and templates without handing reps individual phone numbers. That's a real category, and Heymarket does it well.
Full disclosure: I work for ReadySMS, so I'm not a neutral referee. But I'll do my best to be straight with you, because the worst outcome for everyone is you buying the wrong tool and switching in three months. This post covers where Heymarket genuinely earns its keep, and where a platform like ReadySMS fits better — mainly on send cost, native GoHighLevel sync, a built-in dialer, and done-for-you 10DLC. I won't quote Heymarket's prices or feature list from memory; pricing changes, and you should confirm current numbers on their site before you decide.
Where Heymarket is genuinely strong
Let me start with the case for staying.
Heymarket is built for the team-inbox use case first. If your day-to-day is several reps sharing one number, handing conversations off, leaving internal notes, and keeping a tidy record of who said what, that's the workflow they've optimized. The collaboration layer — assignment, mentions, shared templates, scheduled messages — is mature and pleasant to use.
It also plays in the business-messaging-channel space: many tools in Heymarket's category support WhatsApp, Apple Business Chat, and similar, not just SMS. If your customers expect to reach you across multiple channels in one inbox, that breadth matters and ReadySMS doesn't try to match it.
So if you're a support-heavy team whose primary need is collaborative conversation management across channels, and per-message send cost is a rounding error in your budget, Heymarket may already be the right answer. No need to read further.
Still here? Then your situation probably involves volume, outbound, or GoHighLevel — and that's where the math shifts.
Where the per-message cost starts to hurt
Inbox-first tools tend to price like SaaS: a per-seat monthly fee, and the SMS itself bundled into a quota or marked up on top. That's fine at low volume. It stops being fine the moment you're blasting campaigns or running outbound at scale, because the per-message markup compounds against every send.
ReadySMS is priced the other way around — as a thin layer over carrier infrastructure. Here's the actual outbound rate card, per segment, plus a separate, un-marked-up $0.0045/segment carrier pass-through:
| Tier | Volume / month | Per segment | + carrier | All-in |
|---|---|---|---|---|
| Starter | 0–50,000 | $0.0155 | $0.0045 | $0.0200 |
| Growth | 50,000–500,000 | $0.0125 | $0.0045 | $0.0170 |
| Enterprise | 500,000+ | $0.0028 | $0.0045 | $0.0073 |
A registered SMS lands around two cents all-in at Starter volume, dropping to well under a cent at Enterprise scale. Worked example: a 5,000-contact promo, single segment each, on the Starter tier:
`` 5,000 × ($0.0155 + $0.0045) = 5,000 × $0.0200 = $100.00 ``
Watch the segment count, though — that's where bills surprise people. A 175-character message with one emoji forces unicode encoding, which drops the per-segment limit to 70 characters. That same blast becomes:
`` 5,000 × 3 segments × $0.0200 = $300.00 ``
Three times the cost for one emoji. We break down that trap and the carrier line item in the $0.0045 pass-through post — worth reading before you write your templates. If your monthly volume is in the tens of thousands of messages, the gap between marked-up per-message pricing and near-cost pricing is the difference between a tool that pays for itself and one that quietly eats margin.
Native GoHighLevel integration
This is the cleanest reason to pick ReadySMS over a general team-inbox tool: if you run on GoHighLevel, ReadySMS connects via OAuth with two-way sync of inbound and outbound messages, mapped per location / sub-account.
That last part matters for agencies. Each client sub-account stays isolated, so conversations, numbers, and opt-outs don't bleed across clients. Replies land in the ReadySMS conversations inbox and inside the connected GHL location, so your team can work wherever they already live.
Most inbox-first SMS tools integrate with GHL through Zapier-style bridges or not at all, which means you're patching two-way conversation sync with brittle automations. If GHL is your system of record, a native integration removes a whole category of "why didn't that message show up" problems. We wrote a full GHL SMS setup guide and a best-SMS-provider-for-GoHighLevel buyer's guide if you want to go deeper on this specifically.
Built-in power dialer — not just texting
Team-inbox SMS tools are texting tools. If your sales motion needs calling too, you end up stacking a separate dialer subscription on top, with its own seats and its own data silo.
ReadySMS bundles an outbound Power Dialer: manual and queue dialing, call recording, voicemail drop, transfer / barge / whisper, and speed-to-lead auto-dial on new leads. Plans:
- Free — $0/mo, 1 agent, 1 number, 500 minutes/mo 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. New lead comes in, you fire an instant SMS and auto-dial within the first few minutes — that speed-to-lead window is where most contacts convert or go cold. Doing both from one platform, with both sides of the conversation in one record, beats juggling a texting app and a dialer that don't talk to each other. If dialing is central to your workflow, the PhoneBurner alternative breakdown compares the dialer side head-on.
Done-for-you 10DLC compliance
Any business sending application-to-person SMS in the US needs 10DLC registration, or carriers filter the traffic. This is true with Heymarket, with ReadySMS, with everybody — it's a carrier requirement, not a vendor choice.
What differs is how much of it lands on you. ReadySMS handles brand + campaign registration in-app, with carrier fees of roughly ~$10/mo per brand and ~$20/mo per campaign, approvals typically in 4–7 business days. On top of that, the compliance stack runs automatically:
- Automatic STOP/opt-out handling that propagates across campaigns, so an opt-out sticks
- Quiet-hours enforcement based on the recipient's local time, to reduce TCPA exposure
- 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, full stop. But these guardrails catch the common, expensive mistakes. There's also a standalone TCPA & DNC Litigator Scrub at $0.005 per contact if you're working cold lists; given TCPA exposure runs roughly $500–$1,500 per text, scrubbing a list is cheap insurance. The TCPA-lawsuit-vs-scrubbing math lays that out, and the 10DLC explainer covers registration if it's new to you.
How to actually decide
Skip the feature-matrix paralysis. Three questions sort most teams:
- Is your primary need a collaborative, multi-channel support inbox where SMS volume is modest? Heymarket (or a similar inbox-first tool) is a fair pick. Confirm current pricing on their site.
- Do you run on GoHighLevel, or send enough volume that per-message markup matters? ReadySMS's native sync and near-cost pricing pull ahead fast.
- Does your motion mix calling with texting? A bundled dialer plus SMS in one record beats two subscriptions that don't share data.
If you also resell SMS to clients, the SMS-platform-for-agencies comparison and the tier-breakpoint margin math get into the resale economics specifically.
The practical takeaway
Heymarket is a solid team SMS inbox, especially for support-heavy, multi-channel teams who don't live or die on send cost. I'd genuinely recommend it for that profile.
But if you're on GoHighLevel, sending real volume, or want texting and dialing under one roof with 10DLC handled for you, that's the lane ReadySMS was built for — transparent per-segment pricing that falls to $0.0073 all-in at 500K+/mo volume, native two-way GHL sync, a bundled power dialer, and automatic opt-out, quiet-hours, and litigator scrubbing.
You don't have to take my word for the math. You get 20 free test sends, plus a $25 credit when you submit 10DLC registration — enough to register a campaign, run a real blast, and check your actual all-in cost against whatever you're paying now. No monthly platform fee, no contract. Run the numbers on the calculator or look at the full pricing first, then decide with your own data.
