How to Set Up Your PIONEER Account When the Invitation Email Is Missing

Last updated: October 30, 2026

If your PIONEER invitation email has not arrived, start account setup with the same email address that was invited.

Before You Start

  • The current version of Google Chrome

  • The exact email address that was invited to the organization or project

Set Up and Verify Your Account

  1. Open the PIONEER signup page.

  2. Enter the email address that was invited.

  3. Create a password.

  4. Submit the signup form.

  5. Look for a separate verification email from PIONEER. Check your spam or junk folder if it is missing.

  6. Follow the confirmation link in the verification email.

  7. Sign in to PIONEER with the same email address.

Check That It Worked

Confirm that you can sign in and see the organization or project you were invited to.

Troubleshooting

The Verification Email Has Not Arrived

Allow up to 15 minutes after submitting the signup form. If the message is still missing after checking spam and junk folders, contact Support so the team can check the email address and invitation.

The Email Address Is Already Registered

If PIONEER says the address is already registered and you cannot sign in, contact Support to check the existing account.

The Invitation Went to the Wrong Address, or Access Is Missing

Contact Support if the invitation used a different email address or you can sign in but cannot see the expected organization or project.
