Description of u39379062.ct.sendgrid.net
This domain appears to be a subdomain under sendgrid.net, which is commonly associated with cloud-based email delivery and transactional messaging infrastructure. Based on the hostname pattern and the parent domain, u39379062.ct.sendgrid.net is likely used for link tracking, click tracking, or message-related routing within an email delivery platform rather than as a standalone consumer-facing website.
The parent service is generally used by businesses and application operators to send marketing emails, notifications, password resets, and other automated communications. In this case, the specific subdomain format suggests infrastructure operated within a larger messaging platform environment, likely on behalf of a customer account or campaign configuration rather than an independently branded public site.
Safety Assessment for u39379062.ct.sendgrid.net
Based on available scan data, no threats were detected at the time of this scan. The domain was not flagged by any of the 91 security engines referenced in the scan, the malware scan reported no flagged files, and the checked blacklist and threat-database sources did not indicate known phishing or malware activity.
Additional context also leans benign at this point in time: the domain has a long registration history of about 17 years, uses a valid SSL certificate, and appears to be part of established email-service infrastructure rather than a newly created standalone site. As with many tracking or delivery subdomains, its purpose may be operational rather than intended for direct browsing. Based on available scan data, no significant threats were detected at the time of this scan.
Technical Description
The domain presents a valid SSL certificate issued by a mainstream certificate authority, with expiry listed as 2026-12-13. It resolves to an IP hosted on AWS EC2 in the eu-west-1 region (Dublin, Ireland) and serves content through nginx. The nameservers are provided by a managed DNS platform, and the domain itself is long-established.
DNSSEC appears to be unsigned, which is not uncommon but means DNS responses do not benefit from DNSSEC validation. No technical indicators of compromise were provided in the scan results, and no flagged files, external links, or iframes were reported at the time of analysis.
