The channel built for detail, not brevity
Receipts, invoices, statements, and campaigns — email is where the full record lives. No character limit, no app to check, just a message that sits in the inbox until someone needs it.
Sending domains are authenticated with SPF, DKIM, and DMARC before go-live.

Four kinds of email, one sending infrastructure
Transactional and order emails
Receipts, order confirmations, shipping updates, and invoices — sent the moment an action happens, with the full detail a text message can't hold.

Account and security notifications
Password resets, login alerts, and verification links — sent from an authenticated domain the recipient's mail provider already trusts, so the link doesn't land in spam.

Inbox placement, not just delivery
A message can be "delivered" and still land in spam. Before your first send, your domain is set up with SPF, DKIM, and DMARC records — the three checks mailbox providers use to confirm a message actually came from you.
High-volume senders can move to a dedicated IP, so your sending reputation isn't shared with anyone else's mail stream.
Reputation Guardrails
Bounces and spam complaints don't just affect one message — mailbox providers watch the pattern and throttle or block senders who cross their thresholds. Bounced and complained-about addresses are automatically suppressed from future sends.
This is the same discipline that keeps a sending domain's reputation — and its inbox placement — intact as volume grows.
