Lower friction as you are creating a process that works on multiple OS' without needing to download an app
Also, everyone largely keeps text message notifications on so it's easier to maintain communication compared to relying on the user enabling app notifications
- caseysoftware 11y agoYou nailed it. It gives you 100% market penetration with one system, one UI, and then you can focus on the backend processing and workflows. It also doesn't require data or the like. If you throw in some phone number -> country processing, you can even make some best-guess localization/internationalization with pretty minimal effort. It's a simple but powerful approach. ~ Former Twilio evangelist, so biased :)
- ufo 11y agoI'm curious about how you can deal with security/authentication in these SMS APIs. In theory, sending spoofed SMS messages to Trim would let you cancel someone else's sbuscriptions.
- caseysoftware 11y agoThere are a few tactics but first consider the odds: - First, the target would have to be a subscriber to Trim so that's a small group. - Then you'd have to cancel something they actually have so that further shrinks the group. (Netflix would be a likely candidate.) - But then Trim could thwart most attacks with a simple "Are you sure? If so, respond with " + rand(0, 100) If Trim used a simple Y/N the attacker could spoof that easily. Spoofing a message from another number is relatively easy. Catching Trim's responses is more effort and most attackers aren't going to go to that level of effort.
