iMessage
Send and receive iMessages from a dedicated Apple-registered number, with SMS/RCS fallback, opt-in links, groups and the unified inbox
Send and receive iMessages from a dedicated number that Zernio orders for you on Apple-registered infrastructure. Conversations thread into the same inbox as WhatsApp, SMS and your social DMs, so the send call, webhooks and automations you already use apply unchanged. Contacts who are not on iMessage get the same message as SMS or RCS from the same number.
iMessage is available to every workspace on usage-based billing. Order a sender from the dashboard or the API and it is live within minutes for instant numbers, or within hours for carrier-assigned ones.

How it fits together
- Order a sender. Order a number on a profile; it appears as an
imessageaccount once active. - Bring contacts in. Share an opt-in link so contacts text you first, or message new contacts directly within Apple's pacing.
- Message. Send and receive through the inbox; delivery, reactions and inbound messages arrive on your webhooks.
