Temp mail blocked or not receiving mail
Genmail explains why temp mail can be blocked or fail to receive messages, offers practical checks such as domain blocklists and timing, and clarifies when a permanent mailbox is the right choice.
You pasted a throwaway address and the site rejected it—or the verification never showed up. Here is what is going on and how to move forward without wasting another hour.
Understand blocklists
Many services maintain lists of disposable domains to fight spam and multi-account abuse. A rejection is often automatic, not personal.
Rule out timing and typos
Confirm you copied the full address, waited for slow senders, and still have an active inbox before assuming the provider is broken.
Know when to switch strategies
Banks, government portals, and primary accounts deserve a stable address. Genmail shines on low-stakes signups and trials.
Common reasons temp mail fails
The signup form may validate your domain against a blocklist, the sender may delay or drop mail to unknown domains, or your disposable inbox may have expired mid-flow. Less commonly, corporate filters quarantine messages that look like bulk verification traffic.
What to try before you give up
Generate a fresh Genmail address in case the previous domain was flagged, complete the flow quickly while the inbox is active, and keep the Genmail tab open so you see messages as they arrive. If the site explicitly forbids temporary email in its terms, respect that and use a permanent mailbox you control.
When Genmail is still the right tool
Newsletters, forums, one-off downloads, and short trials rarely need a lifelong relationship with your primary inbox. For those jobs, a working temp mail inbox remains the lowest-friction option when delivery succeeds.
