At a glance
Our take on Sendblue
Sendblue's real selling point is not the discount but the pricing model: a flat $100 per line with no per-message or carrier fees, which is unusual for business messaging and makes costs predictable for high-volume conversational use.
Our code is worth entering because it costs nothing, but choose Sendblue on the merits of iMessage delivery and flat pricing, not for $1 off.
