GET
Segment metrics are currently in private beta and only available to a limited number of users. The response shape might change before GA. Get in touch if you’re interested in testing this feature.Once you have access, upgrade your Resend SDK to use the methods on this page:
Live contact counts for your account, optionally broken down by segment. Works across your whole account by default, or scoped to specific segments via filter[segment_id].
totals is always the live, current count for your account, or for the segments in filter[segment_id], if provided.
Responses are cached for up to 15 minutes, so requesting the same range again may return slightly stale data within that window.
