FAQ
Everything you
need to know.
Answers to the questions we hear most.
Is this real iMessage, or just SMS branded as iMessage?
Real iMessage. Outbound and inbound flow over Apple’s iMessage protocol with the blue-bubble UX your customers already trust. We fall back to SMS only if a recipient isn’t on iMessage, and we surface that distinction in the API so you always know which channel a message landed on.
How is this different from sending SMS through Twilio?
Twilio is an A2P SMS pipe: carrier-filtered, 10DLC-registered, and visibly automated. Chert delivers a peer-to-peer iMessage thread that opens with the blue bubble, supports read receipts and tapbacks, and lives in the same inbox as a recipient’s family and friends. Open and reply rates are categorically different because the channel is.
What about deliverability and spam flags?
Because iMessage is end-to-end and tied to Apple ID, it doesn’t inherit the carrier-side filtering that hammers A2P SMS. We rotate sending identities, warm them gradually, and cap volume per identity per day to stay well below the heuristics Apple uses to throttle abusive senders. Anyone promising "unlimited blast" volume is one ban away from disappearing.
How do I connect Chert to the tools my team already uses?
We expose a REST API and webhooks for every inbound and outbound event, so you can wire conversations into your CRM, sales tools, voice agents, or internal data store with a few hours of work. We also ship native sync for the common cases (lead created, meeting booked, opt-out received). If you’d rather not build, we’ll handle the integration during onboarding.
