What actually differs
They differ on price, delivery, and policy.
Both publish clearly, which already puts them ahead of half this market, and they publish opposite shapes. Sendblue's $100 AI Agent plan buys a dedicated number with no per-message fees and describes itself as inbound-first; full outbound appears only in the Enterprise column, which has no price attached. Blooio's $39 headline is a shared pool where the sender number varies between messages, and the number that stays put costs $289.
So the cheap-looking option is different in each case for a different reason. If you only need to reply, Sendblue is $100 against Blooio's $289 for equivalent stability. If you need to message first, Sendblue's real price is unknown and Blooio's is $289. Sendblue also holds SOC 2 Type II and HIPAA claims that Blooio does not publish.
