I created a user profile before I was listed on imdb. Now I want to associate that previously used email address with my actual name on imdb. If I delete my account associated with my email address, will I be able to associate that same email with my actual imdb page?
Based on your message, it sounds like you may have two separate requests here: (1) updating your email address and (2) claiming your IMDb page.
For the 2nd request, please know that you cannot "claim" an IMDb filmography page with an IMDb.com account. Any IMDb.com user can submit data contributions to any IMDb filmography page; there isn't a connection to be made with an IMDb.com account. If you're looking to claim your page so that you can add photos, demo reels, Known For custom selections, and more, an IMDbPro membership is required.
Regarding your email address update, you're welcome to update your IMDb.com account's registered email address at any time while logged in via the Login and security page in your Account Settings. If you're attempting to update the email address on your preferred account to an email address which is already in use with an unused/unpreferred account, you'll first need to delete the unused account in order to free up the email address.
Please let us know if we can offer any further help.
