If you came to 8x8 for a full phone system and stayed for the SMS, you've probably noticed something: the texting feels like a feature bolted onto a much larger platform, not the thing the platform was built to do. And the contract you signed reflects that — you're paying for an enterprise unified-communications suite whether or not most of your team uses the parts beyond the phone.
Full disclosure: I work for ReadySMS, so I have a side here. But I'll be straight about where 8x8 earns its money before I tell you where a leaner outbound-texting setup makes more sense — because for a lot of teams, 8x8 is genuinely overbuilt for what they actually need.
Where 8x8 is genuinely strong
8x8 is a UCaaS/CCaaS platform — unified communications and contact center, sold as one stack. If you need voice, video, team chat, contact-center routing, and SMS under a single vendor with single sign-on, 8x8 is built for exactly that. The strengths are real:
- One vendor for the whole comms stack. Phone, meetings, chat, and a contact center under one login and one support contract.
- Global voice footprint. If you operate across multiple countries and need international PSTN coverage, that's a serious advantage.
- Contact-center features. Skills-based routing, IVR, analytics, supervisor tooling — the stuff a 50-seat support floor actually uses.
- Compliance and uptime posture. Enterprise security certifications and SLAs that procurement teams like to see.
If that's your reality — a contact center where SMS is one channel among many — 8x8 is a defensible choice and you should confirm current pricing and feature tiers directly at 8x8.com, because UCaaS pricing shifts and is usually quote-based.
The problem shows up when SMS is the main event and the rest of the suite is incidental. You're carrying the cost and complexity of a contact-center platform to send appointment reminders and follow-up blasts.
The mismatch: paying enterprise-suite prices for texting
Two things tend to bite teams using 8x8 mostly for outbound SMS.
First, the contract model. UCaaS is typically per-seat, often annual, often with a minimum commitment. If you have ten people who occasionally send texts and one person who runs the campaigns, you're frequently licensing seats that don't pull their weight on the SMS side.
Second, the SMS itself is rarely the cheapest part. When texting rides on top of an enterprise comms platform, the per-message economics aren't the platform's main selling point — so they usually aren't sharpened. For high-volume outbound, the per-segment cost is where your real money lives, and a slim layer over carrier infrastructure beats a suite add-on most of the time.
That's the gap a focused SMS platform fills.
What ReadySMS does differently
ReadySMS isn't a phone system. It's a messaging platform built to send and receive SMS at scale, sitting as a thin, transparent layer over carrier infrastructure on registered 10DLC routes. Here's the side-by-side at a high level:
| 8x8 | ReadySMS | |
|---|---|---|
| Primary purpose | UCaaS/CCaaS suite (voice, video, chat, contact center) | Outbound + two-way SMS, plus an optional power dialer |
| Contract | Typically per-seat, often annual | Prepaid credits, no seat minimum, no annual lock-in |
| SMS pricing | Bundled into suite tiers (confirm at 8x8.com) | Per-segment, ~1¢ at scale + transparent carrier pass-through |
| 10DLC registration | You handle / coordinate | Done in-app: brand + campaign |
| Free trial | Demo / quote | 20 free test sends + $25 credit when you register |
| GoHighLevel | Not native | Native OAuth, two-way sync per sub-account |
A few of these deserve detail.
Cheap, transparent SMS
ReadySMS bills per outbound segment plus a flat $0.0045/segment carrier pass-through that's itemized separately — not marked up and hidden inside a plan price. Per-segment rates start at $0.0155 on Starter, drop to $0.0125 on Growth (50K–500K/month), and go as low as $0.0028 at Enterprise volume (500K+/month). You can see the full table on the pricing page.
Worked example. Say you send a 175-character reminder with one emoji. The emoji forces unicode encoding, which drops the segment limit to 70 characters — so that message is 3 segments. A 5,000-contact blast on the Growth tier:
`` 5,000 contacts × 3 segments × ($0.0125 + $0.0045) = 15,000 segments × $0.0170 = $255.00 ``
Drop the emoji and rewrite to fit 160 GSM-7 characters and it's a single segment: 5,000 × ($0.0125 + $0.0045) = $85.00 for the same blast. The platform makes that math visible so you can actually optimize it. If trimming your spend is the goal, we wrote up the levers in reduce SMS costs.
Done-for-you 10DLC
US A2P traffic has to run on registered 10DLC routes or it gets carrier-filtered — quietly, with no bounce, so you don't even know your reminders aren't landing. ReadySMS handles brand and campaign registration in-app. Carrier fees run roughly ~$10/mo per brand and ~$20/mo per campaign, approval is typically 4–7 business days, and you're not stitching it together yourself. If 10DLC is new to you, the 10DLC explainer covers it without the jargon.
A built-in power dialer (if you also call)
This is where teams leaving 8x8 for the voice piece sometimes pause — "but I still need to make calls." ReadySMS includes a power dialer as an add-on: manual and queue dial, call recording, voicemail drop, transfer/barge/whisper, and speed-to-lead auto-dial on new leads.
Plans are per agent, billed in 6-second increments:
- Free — $0/mo, 1 agent, 500 minutes/mo, 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 and manager monitoring
It's not a replacement for a 50-seat contact center with skills-based routing — if that's what you run, 8x8 is the better tool and I'd say so. But for an outbound team that wants to text and dial the same list from one place, it's a much cheaper footprint. If calling is your priority, the Aircall and CloudTalk comparisons go deeper on dialer economics.
Compliance you don't have to bolt on
Outbound texting at volume carries TCPA exposure — figure $500–$1,500 per text on a bad day. ReadySMS bakes in the practices that reduce that risk:
- Automatic STOP/opt-out handling that propagates across campaigns, so an opt-out actually sticks.
- Quiet-hours enforcement based on the recipient's local time.
- Litigator and DNC scrubbing — there's also a standalone scrub at $0.005 per contact that checks against known TCPA-litigator and DNC-complainer lists and suppresses matches 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's the difference between defensible practice and crossing your fingers.
Native GoHighLevel (the reason a lot of people switch)
If you run on GoHighLevel, this is the deciding factor. ReadySMS connects via OAuth with two-way sync — inbound and outbound messages flow between the platform and GHL, mapped per location/sub-account so agencies keep each client isolated. 8x8 doesn't offer that; you'd be bridging two systems by hand.
Setup is documented in the GHL setup guide, and you can check the full list on the integrations page.
Who should stay on 8x8 — honestly
I'm not going to pretend ReadySMS replaces a UCaaS platform. Stay on 8x8 if:
- You run a real contact center with IVR, skills-based routing, and supervisor tooling.
- You need integrated video meetings and team chat as core daily tools.
- International PSTN voice coverage across many countries is a hard requirement.
- A single-vendor comms stack is a procurement mandate.
ReadySMS is the better fit if SMS is the workhorse, you don't want to license phone-system seats to send texts, you care about per-segment cost at volume, you need 10DLC handled for you, or you live in GoHighLevel.
The practical takeaway
The question isn't whether 8x8 is good — for full unified communications, it is. The question is whether you're paying for an enterprise comms suite to do a job a focused SMS platform does cheaper and with less friction. If your texting volume is climbing and the rest of the suite is mostly idle, that's the signal.
You can run the numbers on your own volume with the cost calculator, and between the 20 free test sends and the $25 credit when you register 10DLC, there's enough runway to register a campaign, send a real blast, and see the itemized bill before you commit to anything — all pay-as-you-go, no monthly platform fee. That's about the least committal way to compare the two.
