Best text messaging service for business: features, pricing and fit

Most "best texting service" lists rank vendors by how many features fit on a pricing page. That doesn't predict whether a vendor will work for you. Five things do: what a segment actually costs, who handles 10DLC registration and opt-outs, where replies land, what the service plugs into, and whether the API is something your engineers will want to use.

We make Ready, so read our take with that in mind. This guide says where raw carrier APIs and GoHighLevel cost less per segment, and where a per-seat texting app is a perfectly good choice. Use the scorecard to build your own shortlist, whether or not we end up on it.

The five criteria to score every vendor on

1. Pricing. This means the price per segment, not per message, plus carrier fee, registration fees, seats and add-ons. A plan that looks cheap can stop being cheap once emoji and long messages double your segment count.
2. Compliance support. Check who files the A2P 10DLC brand and campaign, how STOP is handled, whether quiet hours are enforced, and whether you can scrub litigator and DNC numbers before a send.
3. Inbox. Replies need to land somewhere a person, or your product, can act on them. A send-only tool is fine for alerts and a liability for anything conversational.
4. Integrations. Look for a native CRM sync versus a Zapier bridge versus nothing at all.
5. API. Check for clean REST, idempotent sends, sub-accounts if you text on behalf of customers, and docs you can read in an afternoon.

The kinds of texting vendor you'll run into

• Raw CPaaS APIs (Twilio, Telnyx, Plivo, Bandwidth). They have the lowest per-segment prices and the most flexibility. You build the inbox, the opt-out logic, the registration flow and the sub-account model yourself.
• CRM-bundled texting (GoHighLevel's LeadConnector). It's cheap per message and fine if you already live in GHL. It's less useful if your product isn't GHL.
• Per-seat business texting (Salesmsg, OpenPhone, Skipio). These have good shared inboxes for small teams. The cost grows with headcount rather than with volume, and they aren't built to be embedded in your software.
• Subscription marketing tools (EZ Texting, SimpleTexting). They're built around campaigns and keywords, with monthly plans that bundle a message allowance.
• Messaging platforms for software companies (Ready). This category sits between a CPaaS and an app: one API, a sub-account per customer with its own numbers and 10DLC registration, and compliance handling built into the send path.

The scorecard

This is a qualitative summary of typical offerings in each category. Individual vendors vary, so check the specific plan you're quoting.

Pricing: do the segment math first

Carriers bill by segment, not by message. A GSM-7 segment holds 160 characters, and longer messages split into 153-character parts. One emoji switches the whole message to unicode, which drops the limit to 70 characters (67 per part). Ready swaps curly quotes, long dashes and ellipses for plain characters before sending, so those don't silently inflate your count. An emoji still does.

Worked example (assumptions stated): an opted-in list of 5,000 contacts receives one promo.

• Version A: 175 characters with one emoji. That's 3 unicode segments, so 15,000 segments. On Ready Standard: 15,000 × $0.0075 = $113, plus 15,000 × $0.0045 in carrier fee.
• Version B: the same offer rewritten to 155 characters with no emoji. That's 1 segment, so 5,000 segments. On Ready Standard: 5,000 × $0.0075 = $38, plus 5,000 × $0.0045 carrier fee.

Version B costs a third of Version A, and the only change was trimming copy. That holds on every vendor, so check segment counts before you compare rates.

Now Version B against the two lower-cost options:

• Twilio at about $0.0083 per segment: 5,000 × $0.0083 ≈ $41.50, before Twilio's own carrier fees.
• LeadConnector at about $0.0128 per message including carrier fees: 5,000 × $0.0128 = $64.00.

On raw sending cost, both of those come in lower than our Standard rate plus the carrier fee, and Twilio does by a wide margin. Ready has one flat Standard rate, and Enterprise pricing is negotiated (talk to us). A Ready quote with the carrier fee included excludes the compliance surcharge. Scrubbing and landline validation each add $0.003 per segment when switched on for an account, and both are off by default.

What the extra cost per segment buys is the work you'd otherwise build or staff yourself. That includes registration, the inbox, opt-out propagation, quiet hours, sub-accounts and a CRM. Per-seat tools and subscription plans are where the math usually tips the other way, especially for teams with many users and modest volume. Price your real seat count against your real segment count. For more ways to cut the bill, see our guide to reducing SMS costs.

Registration is a separate line item on every vendor. On Ready it costs $25/mo for registration and $2/mo per number. There's no setup fee, and the charge at submit is the first month: $25. Most approvals take 2 to 7 days.

Compliance support: where vendors actually differ

Unregistered 10DLC traffic gets filtered by carriers. That alone rules out tools that leave registration to you unless you have someone who has done it before. If you're unsure which sender type you need, our comparison of 10DLC, toll-free, long code and RCS covers it.

Here is what to ask every vendor, and how Ready answers:

• Who files the brand and campaign? On Ready, it's filed in-app, with status available at GET /v1/registration.
• What happens on STOP? Ready honors inbound STOP and UNSUBSCRIBE and propagates them across campaigns. Opted-out numbers are refused before send and not charged.
• Are quiet hours enforced? Yes. Campaigns, drip campaigns and automations wait up to 24 hours for the window. A one-to-one or API text is held only if the window opens within 6 hours; otherwise it is not sent, and you send it again once the window opens. A held text is charged only when it sends.
• Can you screen litigators and DNC numbers? Yes, inline at $0.003 per segment when switched on. You can also run the standalone TCPA & DNC Litigator Scrub at $0.005 per contact. TCPA exposure runs $500 to $1,500 per text, so the scrub is cheap risk reduction, not a guarantee.
• What's recorded about consent? Ready logs the sender's opt-in attestation per bulk send and per API send that sets consent_attested: who sent, to how many, and when. It is not a per-contact consent record, so your signup form or store still needs to keep each recipient's opt-in time, wording and page URL.

None of this makes a sender lawsuit-proof. Compliance stays the sender's responsibility. Our breakdown of TCPA compliance software explains what each layer covers and what it doesn't.

Inbox and integrations

An Inbox matters once anyone replies. On Ready, replies land in a unified inbox and are billed like a sent text, at the per-segment rate plus the carrier fee. Budget for them if your use case invites conversation.

For GoHighLevel users, Ready installs natively via OAuth as an LC Phone alternative. Messages sync both ways and are mapped per GHL location, so agencies keep each sub-account isolated. That's the deepest integration we offer. Outside GHL, Ready connects natively to Close, its App Library links Close, HubSpot, Pipedrive, Salesforce and Zoho CRM to automations, and there is a REST API plus an MCP server at https://api.tryready.com/mcp for AI agents such as Claude or Cursor.

Two add-ons are worth knowing about:

• Blue line (iMessage). Texts show up blue on iPhones with your business name and photo, and no 10DLC registration is needed. It costs $99 a month per line plus 6 cents per segment. Each line can start up to 50 new conversations a day. Campaigns still send from regular numbers. See the blue line guide.
• Ready Dialer. Click-to-call from the dashboard or GHL, billed at $0.025/min for answered time only. It's a manual dialer, not a power or predictive dialer.

API: what to check if you're embedding texting

If you're a platform texting on behalf of your own customers, the API matters most. Check for:

• Sub-accounts with their own numbers and registration (POST /v1/sub-accounts), so one customer's bad list can't take down another customer's sending.
• Idempotency, so a retry never double-sends.
• Bulk limits. On Ready, POST /v1/messages/bulk takes up to 100 recipients per call.
• Opt-out reads (GET /v1/opt-outs), so your app can show suppression state.

A single send looks like this:

POST https://api.tryready.com/v1/messages
X-API-Key: <key>
Idempotency-Key: 3f1c9a2e-7b4d-4c1a-9e2f-5a6b7c8d9e0f

{"to": "+12125550199", "body": "Your order #1042 has shipped.", "consent_attested": true}

Where Ready fits, and where it doesn't

Good fit:

• Software companies that need per-customer sub-accounts, registration and compliance without building them.
• GHL agencies that want an LC Phone alternative with isolated sub-accounts.
• Businesses of any kind (ecommerce, healthcare, local services, nonprofits) that want SMS, a blue line and a dialer in one inbox.

Not the best fit:

• High-volume senders with engineering capacity who only want the lowest per-segment price. A raw CPaaS will win on that metric.
• Teams fully inside GHL who are happy with LeadConnector's price and features.
• Anyone expecting volume discounts or an AI agent that answers texts on its own. We offer neither, and no longer let accounts create AI reply agents. Our AI writes messages and runs a spam-filter check before you send.
• Advocacy, political or fundraising texting without approval first. Email support@tryready.com before the first send and wait for our reply.

How to run your shortlist

1. Write your real message, count its segments, and multiply by your monthly volume.
2. Add registration, seats and any compliance add-ons for each vendor.
3. Ask each vendor the five compliance questions above, and get the answers in writing.
4. Confirm where replies land and what the vendor integrates with natively.
5. If you're embedding texting, have an engineer send one test message from the docs.

If Ready makes your list, the quickstart takes a few minutes. Your first 20 one-to-one texts are free, and to send any text you need a card and a number ($2 a month, the first month charged when you get it). Use those free texts before you register, because they end once a registration is paid for. You can sign up here whenever you're ready to test.
