The most affordable dedicated iMessage API: $49/month

How did we compare iMessage API prices?

We compared the lowest published monthly price for one iMessage phone number, split into two groups, using each provider's own pricing page as of October 25, 2026.

• Managed dedicated, message-first: the provider runs the hardware and the Apple account, the number is yours alone, and your code can send the first message. This is what ZeroSettle sells, so its price is compared here.
• Shared, bring-your-own and inbound-only: a number shared with other customers or users, software that runs on your own iPhone or Mac, or a dedicated line that can only reply. These often cost less and are listed so the comparison is complete.

For each option we note one-time fees, how many new people a number may message first each day, and any metered message fees. What a provider does not publish is marked "Not stated". For background, see what an iMessage API is; for add-ons, contact caps and refund terms in more depth, see iMessage API pricing compared.

What does a managed dedicated iMessage number cost?

From $49 to $300 a month at list price. ZeroSettle Pro and Courio Starter both list $49; the next published price is Miss Blue's $99 sale price. Sendblue publishes no price for a line that can message first.

Courio also lists $49 (Starter: 500 outbound/month, then $0.02/message). Courio's page renders in the browser, so we read its prices from the site's own JavaScript; we found no third-party coverage of Courio. LoopMessage's monthly total is our arithmetic: Light from $59.99 per sender, plus a phone number at $15 a month and Init conversations at $30 a month, with $15 + $30 + $15 (sender name) once. Sendara's figures come from its own guide because its /pricing page returned 404. Project Blue's and Linq's daily limits are from our October 8, 2026 research.

Pro opens 5 new contacts a day per number, fewer than the 30–50 most $99+ plans allow; people who text first are never limited. The $49 comparison is about the price of the number, not about how many new people it can reach. Head-to-head pages: ZeroSettle vs Linq, ZeroSettle vs LoopMessage, ZeroSettle vs Blooio and ZeroSettle vs Project Blue.

What do shared, bring-your-own and inbound-only options cost?

Less than $49 in most cases, from free to $39 a month, with reply-only dedicated lines at $98 to $100. Each gives up something a managed dedicated number has: the number is shared, you run the hardware, or it cannot message first.

Courio also lists $49 (Starter: 500 outbound/month, then $0.02/message); see the first table. Blooio's API pricing page calls the $39 Starter a dedicated number and lists Inbound at $109, while its main pricing page says Starter is a shared number and Inbound is $98; we used the main pricing page.

Which business messaging options are not iMessage numbers?

Two channels often come up in the same search but do not give you an iMessage phone number:

• Apple Messages for Business uses a Business ID, not a phone number, through an Apple-approved messaging service provider. Apple charges nothing; providers quote their own prices. Customers start the conversation. See Apple Messages for Business vs an iMessage number.
• Twilio sends SMS, MMS and RCS from phone numbers, and has had Apple Messages for Business in private beta since May 7, 2026. It does not send iMessage from a phone number.

What do one and three numbers cost a month?

For one number, ZeroSettle Pro and Courio Starter are the lowest list prices for a managed dedicated number, at $49 a month, or $588 a year. For three numbers, ZeroSettle Growth at $599 a month is not the lowest list price: several per-line plans cost less for three lines.

Three-number totals multiply the published per-line price; providers may discount volume. Courio also lists $49 (Starter: 500 outbound/month, then $0.02/message).

What do you get for $49 a month?

ZeroSettle is an iMessage API: a real phone number on real iMessage, running on Apple hardware we operate in a server facility, that your code texts customers from and hears back on. Pro includes:

• One dedicated number that can message first, self-serve from the signup page, with no setup fee, month to month and a 30-day money-back guarantee. Numbers can sell out, in which case there is a waitlist.
• The API: REST with a bearer token, HMAC-SHA256 signed webhooks, inbound messages in about 1–2 seconds and a live server-sent events stream. See send a message and webhooks, step by step.
• AI: a hosted AI agent (Beta) with 500 credits a month, and a remote MCP server at https://portal.zerosettle.io/mcp for setting up from Claude, Cursor and other AI tools.
• iMessage features: photos with captions, voice messages, tapbacks, typing indicators both ways, inline replies, 13 message effects, polls, and your brand name and photo. Group chats (up to 31 people) and video sending are enabled per number on request; videos you receive arrive with the file.
• The limits: 5 new contacts a day per number, at most 2 unanswered messages per contact, up to 10,000 messages a day with known contacts, and no SMS fallback. See errors, limits and compliance.

Growth is $599/month for 3 numbers working as one, plus $199 per extra number, with 50 new contacts a day per number and 1,000 credits a month. You sign up from a Growth link (book a demo to get one). The full product reference is on the ZeroSettle iMessage API page.

When does another option fit better than $49?

No managed provider we checked publishes a lower price than ZeroSettle Pro for one dedicated number, but another option costs less or fits better in these cases:

• You need to message more than 5 new people a day from one number. Growth allows 50 a day per number. Miss Blue, Tuco, Project Blue, Blue Reacher and Linq allow or advise 30–50 a day per line.
• You need three or more numbers on the smallest budget. Three lines from Miss Blue (at its sale price), Tuco, Project Blue (billed annually) or Sendara list below Growth's $599 a month, before setup fees.
• You need to reach Android phones. ZeroSettle has no SMS fallback. Sendblue, Linq, LoopMessage and Photon list RCS or SMS fallback.
• You only answer people who text first, or each of your users needs a number. LoopMessage's $20 shared sender, Photon's $25 shared pool, Blooio Inbound at $98 or Sendblue's $100 inbound-first line may fit.
• You want to keep your existing number or choose an area code. ZeroSettle offers neither. Texting Blue runs on your own iPhone and number for $19 a month; Courio lists port-in on its Growth plan and up; Blooio sells a chosen area code for $75 once.
• You already have a Mac and can keep it running. BlueBubbles is free, and the upkeep and account risk are yours.
• You need a contractual SLA or SOC 2 reports. ZeroSettle publishes neither. Linq lists contractual SLAs on Enterprise and says it is SOC 2 Type II compliant.

How we checked

We checked every price on this page on October 25, 2026, from each provider's own pricing page where one exists, and tested nothing that needs a competitor account.

• For pages that render only in a browser (Project Blue, Photon, Linq, Blue Reacher), we downloaded the raw HTML and read the prices from it. Courio's prices come from its site's own JavaScript bundle.
• Where a figure did not come from a pricing page, the table says so: Sendara (its own buyer's guide), myCRMSIM (press coverage), and the Project Blue and Linq daily limits (our October 8, 2026 research).
• Totals built from add-ons or multiplied across lines are our arithmetic and are labeled as such.
• ZeroSettle's figures come from its signup page and API docs, checked the same day.

We re-check these prices quarterly, and sooner when a provider changes its pricing, and log every change below. To report an error, email founders@zerosettle.io with the source. This page lives at zerosettle.io/blog/cheapest-imessage-api/.
