How long does 0Spam delisting take?

0Spam listings clear automatically once the underlying cause stops — usually within a few days to a couple of weeks. Requesting removal after you've fixed the root cause can speed it up.

Will I get re-listed?

Yes — if the underlying behaviour continues. Delisting only helps if you've actually fixed the cause (secured accounts, cleaned your list, corrected your mail server). Otherwise you'll be back on within hours or days.

How do I know if 0Spam is even affecting my mail?

Run a free EmailHealth check on your domain — it tests your sending IPs against major blacklists and shows which ones list you, alongside your SPF, DKIM, and DMARC status.

0Spam Blacklist Removal: How to Delist

0Spam is a IP and domain blocklist published at 0spam.org. When you're listed, mail servers that consult 0Spamwill block, defer, or spam-folder your messages — so fixing it matters for deliverability. Here's why it happened and exactly how to get off.

Why you got listed

0Spam listings almost always trace back to one of these:

📨

Hitting a 0Spam spam trap address on your list

Most common

Hitting a 0Spam spam trap address on your list. This is the most common trigger for a 0Spam listing — address it first.

How to get delisted

Delisting that lasts has two parts: fix the root cause, then request removal. Skip the first part and you'll be re-listed almost immediately.

1
Find and stop the source
Identify what triggered the listing — a compromised mailbox, a script or web form being abused, a poor-quality list, or a misconfigured mail server. Check your outbound logs for unusual volume and secure any account that looks compromised (rotate passwords, enable MFA, revoke stale API keys).
2
Fix the underlying issue
0Spam provides a delisting request form on its site. Clean the list of trap/invalid addresses, secure your accounts, then request removal. Listings also expire as your reputation recovers.
3
Confirm your authentication is solid
Make sure SPF, DKIM, and DMARC are all passing before you ask for removal — a clean authentication setup is part of demonstrating you're a legitimate sender. Run a free EmailHealth check to confirm.
4
Submit a removal request at 0spam.org
Go to 0spam.org, look up your IP to confirm the listing and its stated reason, and use their removal/delisting form. Many listings here also expire on their own once the cause stops.

💡

0Spam is largely self-correcting: once the abusive behaviour stops and your reputation recovers, the listing clears automatically. The single best thing you can do is fix the cause and let it age out — repeatedly requesting removal without fixing the source does nothing.

Stay off it for good

Keep your list clean — remove hard bounces and never mail purchased or scraped addresses
Authenticate every sending source with SPF, DKIM, and DMARC
Monitor your domain so you catch a new listing within a day, not after customers complain

EmailHealth can monitor your domain daily and alert you the moment a blacklist listing (or any other deliverability change) appears.
