Field guides, customer stories, and engineering notes from the Blooio team on iMessage, RCS, and SMS at scale — written for operators and developers.
Getting an RCS agent approved to send has less to do with the API and more to do with configuration choices made before the first launch request is ever submitted.
Sending a single message is straightforward. Ensuring reliable delivery of millions of messages presents a significant engineering challenge.
If your business relies on SMS, message delivery is more challenging than ever. Carriers use advanced methods to detect spam and noncompliant traffic. Businesses that don't follow A2P 10DLC rules risk having messages filtered, delayed, or blocked.
App Clips, iMessage Apps (app extensions), and rich links are easy to confuse. Here's exactly what each one is, when to use it, and how to send App Clips and iMessage Apps over an API.
On August 5, 2026, Sendblue disclosed a security incident: unauthorized access to conversation records via a Firebase security-rules vulnerability. Here's what Sendblue reported, the data involved, and how to evaluate your iMessage API provider.
Calls are ignored. Emails go unread. Meanwhile, your customer is already texting someone else. Most businesses don't lose customers because of a bad product. They lose them because they stop communicating. Great follow-up keeps customers engaged from first contact to purchase.
Customer communication is changing faster than most businesses realize. Customers expect instant responses, and texting a company often means interacting with AI from the first reply. Businesses are using AI-powered messaging to deliver support and improve customer experiences.
iMessage vs SMS for business messaging in 2026: read rates, cost, security, features, and deliverability compared — plus how to use both with automatic fallback.
iMessage is end-to-end encrypted — but what does that actually mean when you send it through a third-party API? And can iMessage ever be HIPAA-compliant? An honest look at the security claims in the iMessage API market.
Short answer: no — Twilio can't send iMessage, and no SMS API can. Here's why, what Twilio is actually great for, and how to send real blue-bubble iMessages (plus a hybrid mode that uses both).
Wire blue-bubble iMessage into your n8n workflows. Send, receive, and auto-reply to iMessages with the native Blooio node or a plain HTTP Request node — no Mac, no A2P/10DLC registration.
Most 2FA APIs bill you per verification and cap you out. Here's a flat-rate, no-hard-caps way to verify users at scale over iMessage — with a live demo you can try right now.
