Interesting, how are you handling A2P?

Curious, what was the worst thing about Twilio?

FYI I went straight for api examples, and the docs page looks like a placeholder https://docs.postack.dev/quickstart

Absolutely, I get the concern about the docs looking like a placeholder. We're putting a lot of effort into crafting the best SDKs for major languages, so for now, the most comprehensive guide is at https://docs.postack.dev/api-reference/introduction.

Regarding A2P messaging, it's pretty standard: create your brand and campaigns, typically with a 72-hour turnaround. We're streamlining compliance by auto-generating legal documents, webform screenshots using templates, and leveraging ChatGPT to preemptively fix any issues before they reach upstream carriers. It's all about making the process as smooth as possible for you.

Are you running on top of twilio? Where do you get your numbers from?

ufarooqi|1 year ago

We are not running on top of Twilio. We use multiple tier-1 aggregators for redundancy and Twilio is not one of them. In-fact Twilio also uses some of them.

Numbers are sourced from DID wholesalers.
