Send a transactional email through SendByte. The sender domain must be a verified sending domain (or use the shared test domain with a test key). Provide html and/or text, or a template_id with variables. A test key (sk_test_) sandboxes the send.

Fetch one email by id, including its delivery status and event timeline (queued, sent, delivered, bounced, complained).

List recent emails for the project, newest first, with cursor pagination. Optionally filter by delivery status.

List the sending domains on the account with their verification status and whether deliverability (SPF/DMARC/MAIL FROM) is fully configured.

Get one sending domain by id, including the DNS records to publish (DKIM, SPF, DMARC, MAIL FROM) and their current state.

Re-check a domain's DNS records and SES status now, and report which records pass and whether the domain is verified.

List saved email templates for the project (id, name, subject, format, version).

Get one saved template by id, including its subject and body (html/text/mjml).

Render a saved template with sample variables and return the resolved subject and body, without sending anything.

Get daily send counts by status and deliverability rates (delivered, bounce, complaint) over the last N days.

Pre-send deliverability and spam-risk check for email content. Returns a score, risk level, and the specific signals found, so an agent can fix risky content before sending.
