Invaluement (ivmSIP) is a IP and domain blocklist published at invaluement.com. When you're listed, mail servers that consult Invaluement (ivmSIP)will 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
Invaluement (ivmSIP) listings almost always trace back to one of these:
A sending IP with a history of spam or unsolicited mail

A URL/domain inside your email body that points to flagged content

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
Invaluement provides a lookup and removal request form on its website. Because it is a reputation list, you must demonstrate the underlying problem is fixed before requesting delisting.
- 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.

Submit a removal request at invaluement.com
Go to
invaluement.com, look up your IP to confirm the listing and its stated reason, and use their removal/delisting form.
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.
