See every message and its delivery status
Tremi correlates authenticated provider events with the original attempt and keeps acceptance, delivery, replies, and business outcomes distinct.
- Provider and account identity for each attempt
- Authenticated and deduplicated callback evidence
- The original workflow version and result mappings

Use your own Resend account
You manage sender verification, carrier registration where applicable, sending reputation, consent, and provider billing. Tremi checks recipient suppressions before each attempt. Delivery alone does not establish a business goal.
A live workflow start uses 1 Tremi credit. Each accepted attempt uses 1 more. An accepted AI SMS conversation counts once; replies add no Tremi conversation credits. Successful connected-app operations are additional. Provider usage is billed separately.
