UTR

Good afternoon, I received an email on Tuesday saying my self assessment was processed and they will send out a letter to me, today I got the same email again saying my application was processed and they will send me a letter in 10 days. So from which day shall I expect the letter to come within 10 days? Is it tuesday or today or will I get 2 different letters? Thanks

Hi samabdisha1978,
I would expect a letter from both as the Self Assessment may have been amended. 
Thank you.
