Send email
Send an email from the user's connected account; this actually delivers mail, so prefer it over browser automation or leaving a draft when the user asked to send. Three modes: direct (to + subject + body), sending an existing draft (draftId), or replying (replyToMessageId, optionally replyAll) where recipients, subject, and threading are derived from the original. Confirm with the user when intent is ambiguous. Add sendAt to any mode to schedule instead of sending now.

sendAt | No | string | Schedule delivery instead of sending now: ISO 8601 with timezone offset or Z (e.g. 2026-07-11T09:00:00-07:00).

Returns a scheduleId for list/cancel. Format: date-time. |
