Is this really the same email? I've never known about that
Anyone who has had multiple alts and has had a hard time keeping track of them this will help
First you need to be able to change the email
Next create a gmail account for all the alts to go on
Next when changing the email put +1 after user name (example+1@gmail.com)
You can keep making the number go up. I normally only make it go up to 10 and use the same password for those 10 so I can organize them.
Hope this has helped
