Why mail might not arrive

Most of the ways a message fails to reach you here are silent by design.

Work down this list in order.

1. The sender is not authenticated

Our Email Routing rejects inbound mail that fails both SPF and DKIM, mail that fails the sending domain's DMARC policy, and mail from blocklisted IP addresses and domains. This is deliberate and not configurable.

2. No live subscription for the address

The mail is dropped silently. Expired, deleted and replaced subscriptions all look identical from the outside. Check that you registered the exact address, lowercased, on fabricatedemail.com — and not on api.fabricatedemail.com, which is the API, not the mail domain.

3. The account is over its monthly message cap

Free accounts store 60 messages per UTC calendar month, Pro accounts 25 000. Past the cap, mail is dropped silently for the rest of the month.

Where to check: the dashboard shows the number of messages stored this month and the number dropped over the cap. We email the account address at 80% and again at 100% of the cap. An upgrade raises the cap immediately.

4. The account is suspended

Mail is dropped silently while an account is suspended, and every API request answers 403 {"error": "account suspended"}. Reinstatement makes the account work again. Mail that arrived during the suspension is gone, and addresses and mail that expired meanwhile were deleted as usual.

Suspension is taken under the Acceptable Use Policy. Write to support if you believe it was a mistake.

5. The mailbox already holds 1 000 messages

Further mail to that one address is dropped silently. Neither the API nor the dashboard shows these drops.

6. The message is larger than 25 MiB

Rejected by the mail platform at SMTP receipt, before the service sees it.

7. Retention

Mail expires 24 hours after receipt on every tier, and a cleanup that runs every hour deletes it. All email belonging to an expired subscription is removed with the subscription.
