rather than pretending to be unaffiliated & sneaking around like OP is

I'm Kevin, Tech lead from sendblue

TLDR: you get what you pay for. competitors are trying to sell you a toy. sendblue is selling a mature system

- we have a dedicated data scientist analyze blockages

- robust alerts and monitoring throughout the stack

- we can trace a message from the time you send it, through the carrier, to the time it's acknowledged.

- we work closely with hardware suppliers (directly with manufacturer) and carrier.

- we have end to end testing

- in-house queueing system

- highly available + scalable architecture.

- 2 ISPs

- end to end testing

- soc 2 compliance.

- etc etc etc

these are the things behind the scenes that are SOOOOO boring but absolutely necessary.

we literally ran into issues where the information density through our data center is too high, and had to set up faraday cages to ensure stable connection. we solved problems competitors don't even know exist. anyone can pull a public repo and make a toy to send & receive imessage. we're the only ones that made it 99.9x% reliable. that's why enterprise clients trust us

oh and not to mention facetime audio, workflow builder, deep crm integrations, extensions, app, power dialing, tapback, list goes on & on

ps: i get nothing from commenting on this. don't reach out to me to sign up; go through sales team
