If you've shopped for SMS in the last six months, you've probably noticed that "SMS provider" means at least four different things. Each category prices differently, sells differently, and is built for a different buyer. Picking the wrong category is how teams end up paying 3x what they need to for a worse experience.
This guide walks through all four, and explains why Ready is the right answer for the largest segment of buyers.
Category 1: Marketing Platforms (SMS Bundled with Email)
Examples: Klaviyo, Attentive, Postscript, Emotive, Community, Omnisend. Pricing model: Tiered monthly subscription tied to your contact list size. Effective per-message cost: $0.015-$0.04/segment (after you back out the subscription cost).
Built for ecommerce brands with $100K+/month revenue running SMS as a primary acquisition channel. The tools include browse-abandonment automations, Shopify-native flows, and post-purchase sequences that are worth the premium if SMS is your top revenue driver.
The catch: the per-message economics are 2-4x worse than Ready, and the subscription floor often dwarfs your actual usage. Klaviyo's SMS plan starts at $50/mo and scales fast. If your contact list grows to 25,000 you're looking at $400-$700/month before any SMS revenue lands. For most teams, the marketing-platform tax is the worst money in your stack.
Who should pick this: Pure ecommerce, $200K+ MRR, willing to pay the premium for the integrated email-and-SMS automation suite. Almost nobody else.
Category 2: Business Texting Tools (Per-Seat Subscriptions)
Examples: SimpleTexting, Salesmsg, OpenPhone, Heymarket, TextRequest, Avochato. Pricing model: $25-$50/user/month, or tiered subscription with included credits. Effective per-message cost: $0.02-$0.06/segment.
Built for small sales/support teams (2-15 people) who need a shared SMS inbox bolted onto HubSpot or Salesforce. The product replaces the workflow where reps were texting from personal phones.
The catch: the per-seat model gets ugly fast. A 10-person sales team at $40/seat is $400/month before the first message. Most of these tools also expire unused monthly credits, you pay for inventory you don't use, then pay again when you exceed it. The effective per-message rate is 3-7x what Ready charges.
Who should pick this: Tiny support team that exclusively handles inbound conversations, never sends bulk, and doesn't care about per-message economics. A small slice of the market.
Category 3: Developer-First CPaaS APIs
Examples: Twilio, Vonage, Sinch, MessageBird (Bird). Pricing model: Pay-per-segment, usually with carrier surcharges added separately. Effective per-message cost: $0.0105-$0.0124/segment all-in.
Built for engineering teams building custom messaging into their own product. You write code against the API. You handle opt-outs, retries, conversation threading, segmentation, 10DLC registration, and rejection retries yourself.
The catch: the per-segment rate looks competitive on paper, but you also build (and maintain) every higher-level feature Ready ships out of the box. Campaign manager, conversation inbox, drip sequences, opt-out tracking, 10DLC dashboard, all of it costs you 3-6 weeks of engineering time before the first send, plus ongoing maintenance forever after. That's $25,000-$50,000 in labor that doesn't appear on the per-segment rate. (For the Twilio-specific math, see our honest Twilio cost comparison.)
Who should pick this: Engineering teams with bandwidth to build and maintain their own SMS platform from scratch, sending volumes high enough to justify the build (typically 1M+ msgs/month). Niche.
Category 4: Ready (and the Right Answer for Most Buyers)
Ready is built for the buyer that none of the above categories actually serve well: agencies, SaaS teams, and GoHighLevel operators who want to send transactional or marketing SMS at scale, with a campaign manager and inbox UI included, without writing code or paying a per-seat tax.
Pricing: Pay-per-segment via wallet, with the carrier fee passed through at cost.
| Tier | Volume / month | Per-segment | Carrier fee | All-in / msg |
|---|---|---|---|---|
| Ready Standard | 0 to 50,000 | $0.02 | $0.0045 | $0.0245 |
| Ready Growth | 50,000+ | $0.016 | $0.0045 | $0.0205 |
| Ready Enterprise | Custom, talk to us | |||
What's included at every tier (no upcharge, no add-ons):
- Campaign manager with scheduling, segmentation, and A/B testing
- Two-way conversations inbox with team assignment
- Drip sequences and recurring scheduled messages
- 10DLC brand and campaign registration with support team handling rejections
- Native GoHighLevel marketplace install (one click)
- REST API for developer integrations
- Real-time delivery analytics
- Opt-out compliance and suppression lists
- free test sends to try it
Compared to the alternatives:
- vs. Marketing platforms (Klaviyo, etc.): No contact-list tax, no subscription floor, you pay for messages sent, not list size.
- vs. Business texting (Salesmsg, OpenPhone): Up to ~2x cheaper per message at volume, no per-seat charges, scales without re-pricing.
- vs. CPaaS (Twilio): Twilio's raw per-segment rate is lower, but Twilio doesn't ship the campaign manager, conversations inbox, or 10DLC dashboard, you'd build them yourself for $25K-$50K in engineering time, and Ready has you live in minutes with self-serve 10DLC.
- vs. LC Phone (GHL default): Identical carrier delivery, same GHL UI, one-click marketplace install, plus a full standalone platform (campaign manager, inbox, dialer) that LC Phone doesn't ship. (See our full GoHighLevel SMS pricing breakdown for the LC Phone bill anatomy.)
Decision tree, which category fits your situation
``` Are you sending from inside GoHighLevel? ├── YES → Ready marketplace install. Save up to 63% over LC Phone at volume. └── NO → Continue ↓
Are you a pure ecommerce brand doing $200K+/month with SMS as a top channel? ├── YES → Klaviyo or Postscript (you'll pay for it, but the integrated flows are worth it). └── NO → Continue ↓
Do you have an engineering team with 4+ weeks of bandwidth to build a campaign manager and inbox from scratch? ├── YES → Twilio (or roll your own, but expect to spend more in engineering than you save in per-segment cost). └── NO → Continue ↓
→ Ready. Campaign manager, inbox, 10DLC dashboard, drip sequences, GHL install, all included. Pay-per-segment, no per-seat fees, no contact-list tax. Start with free test sends at readysms.io/sign-up. ```
What I'd warn buyers about
Three things most SMS buyers get burned on:
- 10DLC fees compound. Every category requires 10DLC registration in the US. Brand registration is one-time ($4-$15). Campaign registration is ongoing ($10-$25/month per use case). At 10 campaigns, that's $100-$250/month before you send a message. Most pricing pages bury this, our 10DLC registration cost guide itemizes every line. Ready includes brand registration support and bills campaign fees transparently.
- Subscription floors dominate at low volume. Marketing platforms and per-seat tools have monthly minimums that make sense at scale and ruin you below it. Pay-per-segment (Ready) means you pay for what you send, no monthly bill if you're idle.
- The "free trial" is a trap if you don't read the fine print. Most platforms give you a tiny credit pool and hit you with subscription billing on day 8. Ready is pay-as-you-go with no subscription and no auto-conversion, you get free test sends to try it.
