If you're shopping for a Convoso alternative, you're probably one of two people. Either you run a serious outbound call center and Convoso is more than you need right now, or you're a smaller team that got quoted a contract and seat count that made you close the tab. Both are reasonable reactions.
Full disclosure: I work for ReadySMS, so I have a horse in this race. I'm going to try to be straight with you anyway — including the parts where Convoso is genuinely the better pick. There's a real category boundary here, and if you land on the wrong side of it you'll either overpay or underbuy.
Where Convoso is actually strong
Convoso is built for predictive-dialing call centers. That's the core of what it does, and it does it well for that use case. The things you'd buy it for:
- Predictive and progressive dialing that keeps a room of agents fed with live connects, abandoning the no-answers and voicemails before an agent ever hears them.
- Pacing algorithms that adjust dial ratios to keep agents busy without crossing abandonment-rate limits.
- List management and lead recycling at the scale a high-volume call center needs — re-dialing, timezone handling, list prioritization.
- Reporting and workforce tooling aimed at managing dozens or hundreds of agents.
If you have 20+ agents dialing all day and your business is the dial, that machinery earns its keep. I'm not going to quote their pricing because it varies by deployment and seat count — confirm it directly at convoso.com. But it's enterprise software priced like enterprise software, usually with annual commitments and onboarding.
The trouble is that a lot of people evaluating Convoso don't actually have a 50-agent floor. They have a four-person sales team, or a solo operator, or an agency running outbound for a handful of clients. And a predictive-dialer call-center suite is the wrong shape for that job.
The mismatch: enterprise dialer vs. lean outbound team
Predictive dialing only pays off above a certain agent count, because the whole point is amortizing connect rates across many seats. With one to five reps, a predictive dialer mostly creates awkward dropped calls and TCPA abandonment-rate risk. What a small team actually needs is:
- A fast manual / power dialer so reps aren't typing numbers.
- Speed-to-lead — auto-dialing a fresh lead before it goes cold.
- Cheap, compliant SMS to follow up the calls that didn't connect.
- No annual contract or seat minimum to find out if any of it works.
That last point matters more than people admit. The first-five-minutes advantage on a new lead is real, but you don't need predictive pacing to capture it — you need an auto-dial that fires the instant a lead comes in, plus a text that lands while the call rings.
What ReadySMS is, and what it isn't
ReadySMS is a messaging platform with a built-in Power Dialer add-on. It is not a predictive-dialer call-center suite, and I won't pretend it is. If you need predictive pacing for a big floor, Convoso (or a peer) is the right tool and you should buy it.
What ReadySMS gives a lean outbound team is the combination most platforms split across three vendors: registered A2P SMS, outbound voice, and the 10DLC compliance work to make the SMS actually deliver.
The Power Dialer plans, billed per agent, minutes in 6-second increments:
| Plan | Price | Agents | Minutes | Per-min after |
|---|---|---|---|---|
| Free | $0/mo | 1 | 500 included | $0.06 |
| Pro | $29/agent/mo | up to 3 | — | $0.05 |
| Team | $69/agent/mo | unlimited | — | $0.0375 |
The Free tier gives you one number and 500 minutes a month to test before paying anyone. Pro and Team add call recording, voicemail drop, transfer / barge / whisper, and auto-text. Team is where speed-to-lead auto-dial, lead routing, and manager monitoring live.
You can start a trial against your own lead list at the pricing page without a contract or a sales call.
The SMS side is where the real cost gap shows up
Most outbound teams text. The follow-up after a missed call, the appointment reminder, the "you around?" nudge — that's SMS, and it's where the recurring bill quietly grows.
ReadySMS prices per outbound segment plus a transparent $0.0045/segment carrier pass-through that isn't marked up:
| Tier | Volume / month | Per segment |
|---|---|---|
| Starter | 0–50,000 | $0.0155 |
| Growth | 50,000–500,000 | $0.0125 |
| Enterprise | 500,000+ | $0.0028 |
A worked example. Say you've got 5,000 leads and you send a 150-character GSM-7 follow-up (one segment) on the Starter tier:
- 5,000 × 1 segment × ($0.0155 + $0.0045) = $100.
Add an emoji and that 150-char message flips to unicode — the segment limit drops to 70 characters, so the same text becomes 3 segments:
- 5,000 × 3 × ($0.0155 + $0.0045) = $300.
That's why segment math matters more than the headline per-text price. We dig into the unicode trap and other ways the bill balloons in reducing SMS costs. You get 20 free test sends to your own verified number to check deliverability, plus a $25 credit when you submit 10DLC registration — pay-as-you-go after that, with no monthly platform fee.
10DLC, done for you (the part nobody wants to do)
Outbound SMS to US numbers runs on registered 10DLC routes. Skip registration and carriers filter your traffic — your texts quietly don't arrive, and you won't get a clean error telling you why. With a raw CPaaS provider, the registration paperwork is on you.
ReadySMS handles A2P 10DLC brand and campaign registration in-app: roughly ~$10/mo per brand and ~$20/mo per campaign in carrier fees, approval typically 4–7 business days. If you've never done it, the 10DLC explainer walks through what each field means.
The compliance stack that comes with it is the part outbound teams should care about most:
- Automatic STOP/opt-out handling — an opt-out propagates so that contact can't be messaged again across campaigns.
- Quiet-hours enforcement — sends held outside permitted local hours based on the recipient's area, which reduces TCPA exposure.
- Litigator / DNC scrubbing — known TCPA-litigator and DNC numbers screened before send. There's also a standalone TCPA & DNC Litigator Scrub at $0.005 per contact if you want to scrub a list you're importing.
- Consent / attestation capture for an audit trail.
None of this makes you lawsuit-proof — compliance is ultimately the sender's responsibility. But given TCPA exposure can run $500–$1,500 per text, a half-cent-per-number scrub is cheap insurance, and quiet hours plus auto-STOP remove the most common ways teams trip themselves up.
Native GoHighLevel, if that's your stack
A lot of outbound teams and agencies run on GoHighLevel. ReadySMS connects natively via OAuth, with two-way message sync mapped per location / sub-account, so agencies keep client data isolated. Inbound replies land in your conversations inbox and in GHL. If that's your world, the GHL setup guide covers connecting it.
Convoso isn't a GHL-native tool, so if your CRM is GoHighLevel, the integration story alone may decide it.
Who should pick which
Let me be plain about the line:
- Pick Convoso if you run a predictive-dialing call center with a real floor of agents, need pacing algorithms and abandonment-rate controls, and have the volume to amortize an enterprise contract. That's its job and it's good at it.
- Pick ReadySMS if you're a lean outbound team, agency, or solo operator who wants a fast manual/power dialer, speed-to-lead auto-dial, and cheap registered SMS — without a seat minimum, an annual commitment, or doing your own 10DLC paperwork.
If you're somewhere in between, the honest test is your agent count and how much of your day is dialing versus texting and following up. The more it leans toward follow-up, the more an SMS-first platform with a dialer attached beats a dialer-first platform with SMS bolted on.
For a couple of adjacent comparisons that share this shape, the PhoneBurner alternative covers power dialing plus native SMS follow-up, and the Hatch alternative looks at outbound SMS and calling without per-seat sales-engagement pricing.
The practical takeaway
Convoso solves the call-center problem. If that's your problem, buy it. But a large share of people who search for a Convoso alternative don't have a call-center problem — they have a follow-up problem with a dialing component, and they're being quoted call-center software to solve it.
If that's you, the cheapest way to find out whether a dialer-plus-SMS setup covers your needs is to actually run it: grab the Free dialer tier, use your 20 free test sends and the $25 credit you get when you register for 10DLC, send one real campaign and dial one real list, and see what your numbers do. Run your own volumes through the cost calculator first so you're comparing real money, not headline rates.
