MT Intelligence
The domain is a core part of the SendGrid email infrastructure, which has been operational for over 17 years. Our analysis shows a clean record across 92 antivirus engines and no presence on major browser blocklists. The domain is registered to MarkMonitor, a high-security registrar typically used by large corporations to protect their brand assets.

Still, stay alert
No major threat indicators — but a clean scan does not guarantee every page is safe, and phishing emails routinely spoof real domains.
- Double-check the exact URL in your address bar
Confirm you are actually on u26381968.ct.sendgrid.net and not a lookalike like u-26381968.ct.sendgrid.net.com or an IDN homoglyph.
- Use a password manager
Password managers only auto-fill on the exact domain they were saved for — they refuse to fill lookalike domains, which is the single best phishing defence.
- OpenDiscuss this site on the forum
If you have first-hand experience with this site — good or bad — share it with the MalwareTips community.
