Stuck? Start here.

Most answers are already written down. For everything else, a human reads every message — usually the person who built the thing you're asking about.

Check the email's timeline in your dashboard first — queued, sent, delivered, bounced. Nine times out of ten the answer is there with a timestamp.

Every error carries a request_id. Search the API reference for the code, then quote the ID if you write in.

DNS propagates slowly and fails silently. The deliverability guide walks through the usual suspects.

Usage is metered from the same records you see in the dashboard. If an invoice ever disagrees with them, that's our bug — tell us.

Still stuck

Write to support@calder.click with your request_id or email id. Migrations from other providers get white-glove help — see the migration guide.

Check status first during an active incident — that's where we post timelines.
