How emails are counted
- The count is per account (all your sites together) and resets on the 1st of each month (UTC).
- Only emails sent in relay mode — from
[email protected]— count. Emails sent from your own verified domain do not count toward the limit. - An email counts once it is accepted for sending. Rejected and held emails do not count.
- An email to several recipients counts as one.
At the limit
When the month’s count is used up, POST /mail/send answers {"ok": false, "reason": "over_quota"} with HTTP 200 and the email is not sent. The WordPress plugin then sends it with WordPress’s own mailer, so site email keeps working. Form submissions over the limit are still saved; only the notification email is skipped (email_sent: false).
