Log an email

client.Email.Log(ctx, body) (*EmailLogResponse, error)

POST/v1/emails/log

Logs an email that no connected account will sync, such as history from a previous CRM or a mailbox export. The email appears on account, contact, and opportunity timelines at $sentAt and threads with related emails. $sentAt must be in the past, and at least one participant must be a workspace member and one must be external.

The Message-ID header (or a generated one) identifies the email. If an email with the same Message-ID already exists, the request returns 409 and writes nothing. Group emails into threads with $threadId, or pass In-Reply-To and References in headers.

Privacy defaults to the most permissive setting among the participants’ connected accounts, else METADATA. Set $privacySetting to override it. Logging an email never sends it, never cancels a sequence enrollment, and creates records only when autoCreateRecords is true. Filter out personal and non-sales mail before logging.

Supports idempotency via the Idempotency-Key header.
