Overview

Mercor provides expert email addresses to facilitate secure access to project resources. These email addresses are designated for accessing project-mandated tools, documents, and communications.
Effective from February 12, 2026, Pacific Time, all experts engaged in active projects will be granted access to the @mercor.expert email via their Okta accounts.

Experts who previously had access to the @c-mercor.com email will retain access to both email addresses for a transitional period to facilitate content migration. 
Mercor is introducing a new Okta-managed email system for experts: @mercor.expert.
This page explains what it is and how it works.

​
What Is the Mercor Expert Email?

The Mercor Expert Email (@mercor.expert) represents a newly established Google Workspace account designated for experts working Mercor projects. It is utilized to securely access:
  • Google Docs, Sheets, and Drive;
  • Facilitate project-related internal communications;
  • Access tools that necessitate identity verification.
This system is intended to gradually supersede the legacy @c-mercor.com email address.

​
Important: Contractor Email and Okta Are Different

Your @mercor.expert email is not authorized for Otka login. Access to Okta is limited to your personal email address associated with your work.mercor.com account.

​
Key Distinction

PurposeEmail Used
Log in to work.mercor.comPersonal email
Log in to OktaPersonal email
Access Google WorkspaceManaged via Okta
Your expert email is a project resource account and does not function as an Okta login credential.

​
What Is Changing and What Is Remaining Unchanged

What’s New

• New anonymized @mercor.expert email
• Access managed through Okta
• Secure Google Workspace access

What’s Not Changing

• You still log into Okta with your personal email

• Slack, Insightful, Stripe, Feather, and other tools are unaffected

​
Your New Email Address

Your new email will not include your actual name. Instead, it is an anonymized, randomly generated address composed of scientific or nature-related terminology, for instance: [email protected]
This is anticipated and deliberate.
The anonymized format safeguards your identity while maintaining consistent access across various tools.
You may verify that this email address is yours by:
  • Reviewing your Slack profile
  • Accessing the Google Workspace application in Okta

​
How to Access Your Mercor Expert Email
