Thanks for feedback. But sadly that makes it unusable in "non-english" markets.

Aside from the language issue, some providers are using specific opt-out keywords to filter messages. This will negatively affect deliverability. A2P only requires an opt-out method and does not set specific works to use for triggering an opt-out. Is the opt-out going out with every single message?

@klemen we understand. Thanks for considering us :)

@mcorona it goes out when they join the list but not with every message afterward. That said, if they reply stop they will be opted out and our system doesn't allow you to change the opt-out keyword.
