Common Questions
These are answered in detail elsewhere on the site — worth checking before emailing.
My email never arrived
Most missed emails are caused by the sending service blocking disposable email domains. If the verification email doesn't arrive within 60 seconds, try refreshing the inbox. If it still doesn't arrive, the sending service is likely blocking the @tempmailgrab.com domain — this is not something we can fix on our end. Consider using a custom prefix or check if the service accepts the address before sending.
How long do emails last?
Inboxes expire after 24 hours by default. Emails are deleted when the inbox expires. Developer accounts can configure longer TTLs (up to 72 hours) via the API. See the complete guide for details.
Can I use a custom domain?
Yes — Bring Your Own Domain (BYOD) is available now on the developer tier. Sign in to the dashboard, go to "Domains", and add your domain. Verification takes under 5 minutes via a DNS TXT record. Once verified, you can create inboxes at anything@yourdomain.com through the API or dashboard. Email api@tempmailgrab.com if you need help with the setup.
I found a security vulnerability
Email security@tempmailgrab.com with "Security" in the subject line. We follow responsible disclosure: we'll acknowledge within 24 hours and aim to ship a fix within 7 days for critical issues. Please don't publish details until we've had a chance to patch.
About the Service
TempMailGrab is a small team. We don't have a support chat widget, a phone number, or a ticketing system — email keeps things simple and gives you a paper trail. See the About page for the full story of who built this and why.
