Answer
Your SendGrid account was suspended because a domain used in your email content was flagged by SURBL as malicious or associated with phishing. This can happen even if the domain is your own or a domain you trust.
Domains can be listed by SURBL for a variety of reasons, including:
- Being compromised or hijacked by bad actors.
- Hosting phishing or malware content.
- Being referenced frequently in spam campaigns, even unintentionally.
- Redirection to harmful websites.
To resolve a suspension due to a SURBL listing, follow these steps:
-
Check the domain status:
- Visit SURBL Lookup Tool and enter the domain(s) in question to confirm if it is currently listed.
-
If the domain is listed:
- Review the security of the domain and ensure it is not hosting or redirecting to malicious content.
- Work with your hosting provider or web administrator to fix any issues or vulnerabilities.
-
Request removal from SURBL: If you've fixed the issue or believe the listing is in error, you can request a delisting directly through the website, scrolling down you can fill out the removal request form:
