  • My email was blocked by 0spam, why?
    • 0spam does not block emails, we provide a report on senders based on spam trap triggers. Mail servers may be configured to bounce, delete or place mail that is flagged by 0spam in a spam folder.
  • Why is my email blocked?
    • Email may have been blocked based on its 0spam reputation by an email provider that you sent to. You should contact your IT or email provider in order to resolve the listing.
  • How do I unblock my email address?
    • 0spam does not block or list by email address, our services list reputation codes based on IP or URLs.

  • How is the 0spam project supported? ◦
    • You can request whitelist access. White list access works in the following way. When an IP that you have management of sends spam to one of our spam traps we will notify you. Once a notification is sent you will have 24 hours to login to our backend and confirm you have resolved the issue. Once you confirm you have resolved the issue no other action is nessisary. If you fail to confirm resolution within 24 hours the IP will be listed like normal and will require removal.
