You can update your email address on your own via the Bonfire Settings page. First log into the portal you registered with (will be a link that looks like "example.bonfirehub.com" or "example.bonfirehub.ca"), click the chevron beside your name in the top, then click Settings. On the sidebar, click the Email and Password tab and enter your new email in under Change Your Email.
Click the Change button when done. Please note that you will have to enter your current password in order to change your email successfully. Once the change is made, you will have to confirm your email address again.
You have now changed your account login email! However this will not change the email address displayed within Bonfire to buyers and other users. To change this, update the Contact Email fields under the Organization Vendor Record and Global Vendor Record tabs:
Please note that if you are registered with several organizations on Bonfire, you will have to log into each organization's portal and edit the Contact Email field under the Organization Vendor Record for every organization you're registered with.
