Contact support

Have a question or need help? Send us a message and we'll get back to you, usually within one business day.

Send a message

Include any account email or domain that's relevant so we can find you quickly.

Before you write — faster answers

  • Is something down? The status page shows live health for the API, SMTP relay, and mailboxes, plus 90 days of uptime history.
  • Setting up or debugging a send? The documentation covers every endpoint, and the error reference explains each error code and how to fix it.
  • Mail not arriving? Open the message under Emails in your dashboard: its event timeline shows whether it was delivered, deferred, or bounced, with the receiving server's exact response.

What to include

The sending domain, an email ID or recipient address if a specific message is involved, the time it happened (with time zone), and the exact error text. Never include an API key — we will never ask for one.

Response times and other contacts

Paid plans get the first-response times in our Service Level Agreement; everyone else hears back on a best-effort basis, usually within one business day. Support is run from Denmark (CET/CEST).
