What actually differs
They differ on price, delivery, and policy.
Linq publishes the most capable feature list in this comparison: triggering tapbacks and read receipts, managing group threads programmatically, starting and scheduling FaceTime calls, and sharing live location through Find My. It also publishes no price at all, only a sandbox, an Enterprise tier and a contact form. Sendblue publishes $100 a month per dedicated line and a free sandbox.
Both state SOC 2 Type II. Compliance claims on this site are recorded as the vendor states them and are not verified by us, so if this is genuinely a requirement, ask each provider for the report rather than relying on a page. Linq also operates imessage.store, a competing directory of iMessage agents.
Linq is for
Teams who need tapbacks, typing indicators, group threads, FaceTime and Find My, and will go through sales to get them.
Sendblue is for
Teams who want to know what it costs before the first call.
