2 accounts and two different emails

Can I merge 2 separate accounts with two different emails? One account I must have forgotten I had. My last rating (824ttl I think) was in 2023. The 2nd account with almost 800 ratings was last rated a few days ago. Both email addresses are from two different domains I own (yup, I own my own domains (5ttl so I have unique email addresses.

I’d like to merge both accounts into one account (delete the other) with only one of emails.

Is this possible?
