How they write addresses
Lambda email format
How Lambda writes its people's work addresses, read from addresses an email verifier confirmed.
The format, on a made-up name
Lambda writes addresses as first name, a dot, then last name, at lambda.ai. Jane Doe isn't a real person: put in the name of the one you want to reach.
Writing to someone at Lambda
Find the person
For a role, that's the hiring manager or whoever leads the team. The posting, Lambda's team page or LinkedIn usually names them.
Write their name as Lambda does
Lowercase, with accents dropped: Jane Doe is [email protected], and Zoë Núñez would be [email protected].
Check it before you send
An email verifier tells you whether the mailbox exists without sending anything. A bounce costs more than the check: too many and your emails start landing in spam.
If it bounces

Lambda email format: frequently asked questions
What is the email format at Lambda?
Lambda addresses use first name, a dot, then last name at lambda.ai, for example [email protected]. Both Lambda addresses we've verified follow it. As of October 2026.
How do I find a recruiter's or hiring manager's email at Lambda?
Find their name first: the job posting, the team page or LinkedIn usually has it. Then write it the way Lambda does, so Jane Doe would be [email protected], and check the address with an email verifier before you send.
What if my email to Lambda bounces?
Check the spelling of their name first. Then try the next most common formats at startups: [email protected] and [email protected]. Someone who goes by a short name may use it in their address too.
How do you know Lambda's email format?
From addresses we've found for Lambda's people and checked with an email verifier, which asks Lambda's mail server whether each mailbox exists without sending anything. Only mailboxes the server confirmed count: a server that accepts every address confirms guesses too, so those are left out. Both Lambda addresses we've verified follow it.
