What is your plan to prevent spam from bad actors?

How do you ban bad actors so they can't spam again?

Does a user have to initiate contact in order to have messages sent to them?

1. Since we're not fully self-serve right now, we can choose to only partner with businesses with use cases that are opt-in and non-spam. 2. If we find that one of our customers is using this for spam, we'll reach out to them asap and determine next steps 3. Not necessarily. We support both inbound (user texts the phone line first) and opt-in outbound (we text the user first) use cases

And what would be the next steps? Would you block them from using your services, even if they are paying customers? Do you have agreements in place with your users to cover those situations? Is there a way for end users to report to you what they see as spam or unsolicited content? How do you monitor customers activity to determine if they are bad actors?

You should have answers for those points if you want to build trust with end users

For prospective customers, we would most likely try to work with them to brainstorm use cases that are consent-based and non-spam. For current customers, if we do see that they're using our services for spam, we'll reach out to them asap.

Also, while we can't see the exact messages that our customers are sending due to encryption on our servers, we do know when a phone line is close to being banned from our health checks. When that happens, we'll reach out to our customers asap and learn more about what is going on.

How do I as an iOS user permanently opt-out of your services before I get spammed to death with them?
