Messaging channels

One agent across iMessage, WhatsApp, SMS, email, and more, with every conversation in one thread, with consent and opt-outs synced everywhere.

RevDesk runs your follow-up on the app your customers actually answer. Voice, iMessage, WhatsApp, SMS, and email are first-class channels; Telegram, Instagram, Slack, and Discord extend the same agent to community and team surfaces. Whatever the channel, everything writes to one contact record, so the thread is never lost.

Why channel choice matters

iMessage sees 3–4× higher engagement than SMS (industry benchmark, open + reply rates). A reminder that gets ignored as a green bubble gets answered as a blue one. RevDesk picks the best available channel for each contact and falls back automatically: iMessage where it’s available, WhatsApp or SMS where it isn’t.
