Official Lambda site and email domains
This page lists every domain Lambda uses for its websites and email, so you can check whether a message or link really comes from us.
Current domain
- lambda.com: our website, product pages, and email from November 5, 2026, onward, including subdomains such as cloud.lambda.com, docs.lambda.com, support.lambda.com, files.lambda.com, trust.lambda.com, and more.
Legacy domains
You may still see email and links from these domains. They and their subdomains belong to Lambda and remain legitimate. Over time, links on these domains will redirect to lambda.com.
- lambda.ai
- lambdal.com
- lambdalabs.com
If a domain isn't listed here, it isn't us
Check the full sender address, not just the display name, since display names are easy to fake. Watch for lookalike spellings, like an extra letter or a hyphen added to lambda.com.
Report a suspicious message
If you get a message that claims to be from Lambda but comes from a domain not on this page, don't click links or open attachments. Forward it to security@lambda.com and delete it.
