No Solicitado is a IP and domain blocklist published at nosolicitado.org. When you're listed, mail servers that consult No Solicitadowill 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
No Solicitado listings almost always trace back to one of these:
Spam complaints from recipients on Spanish/Latin American ISPs
Most commonSpam complaints from recipients on Spanish/Latin American ISPs. This is the most common trigger for a No Solicitado 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
No Solicitado provides a delisting form on its website. Fix the underlying list-quality or compromise issue first; listings also age out as complaints stop.
- 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 nosolicitado.org
Go to
nosolicitado.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.
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.
