How this service works
Get the email format patterns used by a domain (e.g. first.last, firstlast).
Output
Returns the email format pattern(s) used by the specified domain, such as 'first.last@domain.com' or 'firstlast@domain.com', along with pattern examples and prevalence data to help construct or guess employee email addresses.
Example use cases
Construct prospect email from name
“I have a lead named Jordan Smith who works at acmecorp.com but I don't have her email — can you look up the email format they use so I can piece together her address?”
Find recruiter contact at company
“I'm trying to reach the hiring manager at notion.so and I know their name but not their email — what email naming convention does that company use so I can take a guess?”
Bulk outreach email construction
“I've got a list of contacts with their names and company domains but no email addresses — can you pull the email format patterns for each domain so I can construct the right addresses before sending outreach?”

Endpoint
GEThttps://mpp.orthogonal.com/tomba/v1/email-format?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to determine the email address format convention for a specific company domain before constructing or guessing employee email addresses for sales outreach, recruiting, or contact research. Prefer this over generic email guessing when you want data-backed format patterns rather than assumptions.
