30961: Campaign rejected: high-risk domain reputation detected

Your A2P 10DLC campaign was rejected because one or more URLs in the campaign have a poor domain reputation or are flagged in threat intelligence databases. Campaign reviewers evaluate the reputation of all domains referenced in campaign content, including website URLs and sample messages. Domains associated with malware distribution, spam, phishing, or other malicious activity are grounds for campaign rejection.

• Domain flagged in threat databases: The website URL associated with your campaign appears in one or more threat intelligence or domain reputation databases as malicious or suspicious.
• Recently registered or disposable domain: The domain used in the campaign was recently registered, has no established reputation, or uses a disposable domain service commonly associated with fraudulent activity.
• Compromised or previously abused domain: The domain may have been previously compromised or used for spam, malware distribution, or other abuse, resulting in a poor reputation score.
• Shared hosting with malicious sites: The domain is hosted on infrastructure shared with known malicious websites, resulting in a negative reputation by association.

• The rejected campaign is not eligible for resubmission. The domain's reputation score does not meet the minimum threshold required for A2P 10DLC campaign approval.
• Check your domain reputation using publicly available tools (for example, Google Safe Browsing, VirusTotal) and work to remediate any issues before registering a new campaign with a clean domain.
• If you believe this rejection was made in error, contact support.
