Short answers, no hedging.
Emails received, per UTC calendar month. Creating inboxes, listing them, polling /wait and deleting things are all free and unmetered. Anonymous inboxes made on the public homepage don't touch your account at all.
Incoming mail is rejected at the SMTP envelope with a soft failure and the API returns 402. Nothing is silently dropped, and existing inboxes keep working for reading. Every API response carries X-Quota-Remaining so you can see it coming.
Because every shared disposable-mail domain eventually ends up on a blocklist, and then your own signup form starts rejecting your test addresses. A domain you own never gets flagged. That's the single biggest reason teams move to Pro.
No. InboxWire is receive-only by design. That keeps us off spam blocklists and keeps the service cheap for you.
Until the inbox expires, then a sweeper deletes them within a minute. There is no archive and no backup of your mail. Set ttl_seconds to what your test actually needs.
Yes, from the dashboard, and you keep the plan until the end of the period you paid for. No annual lock-in, no cancellation email to write.
Two months free on annual — $190 for Starter, $990 for Pro. Email us and we'll invoice you.
