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
Open the PIONEER signup page.
Enter the email address that was invited.
Create a password.
Submit the signup form.
Look for a separate verification email from PIONEER. Check your spam or junk folder if it is missing.
Follow the confirmation link in the verification email.
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.
