LoopMessage vs Sendblue: which iMessage API
The axis is bundling. Sendblue quotes one number that includes the number, the fallback and the media handling; LoopMessage quotes a lower number and sells each of those separately.
LoopMessage is for
Teams who want to pay only for the pieces they use and are willing to price the assembly themselves.
Sendblue is for
Teams who would rather have one figure that already includes everything the product needs to work.

What actually differs
They differ on price, delivery, and policy.
LoopMessage's $59.99 Light plan looks cheaper than Sendblue's $100 until you add what it excludes: a phone number is $15 a month, SMS and RCS fallback with call forwarding another $15, and the ability to initiate conversations $30 more. Assembled, that is roughly $120 for a product comparable to what Sendblue quotes at $100 with a dedicated line included.
The unbundling is not automatically worse. If your agent never initiates and never needs fallback, LoopMessage genuinely is cheaper, and it meters by unique active daily contacts rather than by messages, which suits a product with a wide but quiet user base. Sendblue's catch is the reverse: outbound is not an add-on you can buy, it is an Enterprise tier with no published price.
