MailSlurp inboxes can be set to expire at a given time. The server periodically checks inboxes to see if they have expired and archives those that have.

Expired inboxes

You can view inboxes that have expired with the endpoints in the inbox controller or in the dashboard.

Emails

Expired inboxes can no longer sender or receive emails. You can however view old emails using the inbox's ID.

Expiration causes

If you have a free account a default expiration date is used when creating inboxes. Paid accounts can set whatever expiration dates your desire or leave the property blank for permanent inboxes by default.

Permanent inboxes

To ensure permanent inboxes use a paid account or upgrade your account.

Working with expired inboxes
