I logged in for the first time and created new email in the new email parser from my personal account - then I logged out and logged in with my work account and I saw the same emails list in it.
I went to a different computer (work computer - that I never logged in with my personal email) - then logged in with the work email and found the same emails, so I decided to create new email address but this time while logged in from my work email.
then when I went back to my personal account I found all existing emails + the newly created one from my work.
Seems like I have parser account linked to 2 zapier accounts.
