Twilio SMS question about "Attempt to send to unsubscribed recipient"

Does anyone here use Twilio sms?

When I try to send to a number that opted out, it returns the "Attempt to send to unsubscribed recipient" error. Does it count in the message queue? Because we only have so much message throughput meaning you can only send so many messages at one time.

I should probably add something in the code to log people that unsubscribed so that way I don't attempt to send them messages if it does count in the message queue

i guess twilio is flagging your SMS as a SPAM because the recipient did not subscribe or agree to receive it. Years ago SMS was a piece of cake but the past 2-3 years they are very sensitive and requires KYC process. The dumb thing about these platforms is your purchase their credits and launch a campaign, then they will block the campaign till you complete KYC. If you don't you won't get your money back
