Must know
- Photos, files, and attachments aren’t supported anywhere in chat — messages are text only, on every channel.
- SMS messages have a stricter length limit than web or email, and an over-long text is rejected rather than trimmed.
- Web Only and Web & Email comfortably handle long messages — write as much as you need.
- Web & SMS has a tighter cap, because a text message can only carry so much. If a message you’re sending over SMS is too long, the send is rejected and you’ll see an error rather than a truncated text going out. Shorten it, or split it into two, and try again — or switch the conversation to Web & Email when you have a lot to say.
