Blooio

Messaging infrastructure across iMessage, RCS and SMS, sold on delivery reliability and instantly available pre-warmed numbers.

Visit Blooio

Overview

The pitch here is operational rather than featural. Blooio sells uptime, delivery status, logs and fallback routing for teams that, in their words, need messaging to work every time. If you have been burned by a provider whose numbers went quiet without explanation, that framing will land.

Pre-warmed numbers are the concrete differentiator. Blooio keeps a stock of production-ready iMessage numbers, restocked on a 48-hour cycle, so a new line is available immediately rather than after a warm-up period. For an agency spinning up lines per client, or a business that needs to replace a flagged number quickly, that is a real operational advantage.

There is a purpose-built Inbound Plan aimed at AI agent workflows that start reply-first — meaning the agent responds rather than initiates. That is a sensibly-designed product for a genuinely common pattern, and it tends to be cheaper than a full outbound line.

The API covers iMessage, RCS and SMS with webhook delivery events, real-time typing indicators, and the ability to initiate FaceTime audio and video calls. Their headline commercial claim is no segment fees — you are not billed per 160 characters the way SMS aggregators bill you.

What stands out

What Blooio does well

Pre-warmed numbers, available now

A stock of production-ready lines restocked every 48 hours, so provisioning is not a waiting game.

No segment fees

Not billed per 160 characters, which removes the main hidden cost of SMS-style pricing.

Built for fallback

Delivery orchestration across iMessage, RCS and SMS is the core product, not an add-on.

OpenAPI specification

A machine-readable spec means generated clients and less guesswork than prose documentation.

FaceTime calls from the API

Initiate FaceTime audio or video from the same integration that sends messages.

An inbound-only plan

Priced for reply-first AI agents rather than making them pay for outbound they will not use.

Pick Blooio if

Agencies provisioning lines per client who cannot wait on warm-up
Teams replacing a flagged number under time pressure
AI agents that answer rather than initiate, via the Inbound Plan
Anyone who wants an OpenAPI spec rather than hand-written docs

Look elsewhere if

Buyers who need transparent published pricing without a comparison page
Teams wanting a shared inbox — this is infrastructure, not an app
Small businesses at the low end; per-line pricing sits above the entry tiers elsewhere

The API

Send a message

Note the link in the message body — it carries UTM parameters, so when the customer taps it the visit is attributed to this exact campaign instead of vanishing into direct traffic.

Illustrative only

How the tagging works

bash

# Shape is illustrative. Generate a client from Blooio's OpenAPI spec.
curl --request POST 'https://api.blooio.com/v1/messages' \
  --header 'Authorization: Bearer YOUR_API_KEY' \
  --header 'Content-Type: application/json' \
  --data '{
    "to": "+19998887777",
    "text": "Your tech is 20 minutes out. Track: https://acme.co/track?utm_source=imessage&utm_medium=messaging&utm_campaign=status-update"
  }'

Illustrative shape only. Blooio publishes an OpenAPI specification — generate a client from that rather than copying this.

Before you commit

Do this first

The sandbox is free on every provider in this category. There is no reason to sign a contract before you have sent yourself a message.

Create the free sandbox account and send a message to your own phone.
Check what share of your customer list is actually on iPhone — your CRM may already know.
Write the three messages you would send most often, and read them out loud.
Tag the links in them before the first send, not after.
Run one play on a slice of your list and compare it to what you send today.
