Invaluement blocklist: check and removal guide

Invaluement is a third-party anti-spam operator that publishes several DNS-based blocklists used by some spam filters to flag suspicious domains and sending IPs. If your domain or IP appears on an Invaluement list, some recipients may see your mail filtered to spam, rejected, or delayed—depending on how their provider uses the list.

What is Invaluement?

Invaluement maintains multiple blocklists that focus on different spam signals:

• InvaluementURI: Lists domains and IPs found in URLs inside spam messages (i.e., link destinations).
• InvaluementSIP: Lists sending IP addresses that are observed sending a high percentage of spam.
• InvaluementSIP/24: Lists larger IP ranges (a /24 network) when spam patterns are detected across related IPs.

These lists are commonly consumed by security gateways and spam filtering systems to help identify unwanted mail.

Why am I listed?

The most common reasons for appearing on an Invaluement list map to the list type:

• Listed on InvaluementURI

  • Your domain (or a domain you control) appears in links inside messages classified as spam.
  • Common causes include compromised websites, abused tracking domains, or links used by affiliates/third parties in ways that trigger spam complaints.

• Listed on InvaluementSIP

  • Your sending IP is associated with high spam rates, complaint rates, or poor list hygiene (e.g., many invalid recipients).
  • This can also happen if you’re on shared infrastructure and another sender on the same IP is generating abuse.

• Listed on InvaluementSIP/24

  • Multiple IPs in the same /24 range show spam-like behavior, causing the entire range to be blocked.

How does this affect deliverability?

Impact varies by recipient environment, but common outcomes include:

• Spam folder placement (reputation-based filtering)
• Temporary deferrals (messages delayed and retried)
• Hard rejections (mail refused at the gateway)

If only some mailbox providers or corporate gateways use Invaluement, you may see deliverability issues limited to specific recipients rather than across your whole list.

To quickly confirm whether you’re listed, run your domain and sending IP through InboxAlly’s free Spam Database Lookup.

How to get removed from Invaluement’s blocklists

Invaluement supports manual delisting requests, but removal typically requires you to fix the underlying cause first. A practical remediation flow:

1. Identify what’s listed

   • Check whether the listing is for your sending IP, your domain, or a linked/tracking domain used in messages.

2. Stop the behavior that triggered the listing

   • Pause or reduce sending from the affected IP/domain if you’re seeing active filtering.
   • Fix list hygiene issues (remove invalid addresses, reduce bounce rates, confirm opt-in where applicable).
   • If the issue is URI-based, audit the domains in your links:
     • Remove/replace suspicious redirect chains
     • Ensure your website isn’t compromised
     • Disable abused subdomains or tracking endpoints

3. Request delisting from Invaluement

   • Submit a delisting request through Invaluement’s published process (their website/removal page).
   • Be prepared to explain what changed (e.g., compromised page cleaned, sending reduced, list cleaned).

4. Monitor for relisting

   • Relisting is common if sending patterns or link usage return to the previous risk profile.

For ongoing monitoring inside InboxAlly, use Domain Reports (in the InboxAlly app) to track domain reputation and authentication status over time.
