Hi @Naee-6456 thanks for posting your question!
A way to accomplish what you are looking to do is create a column in your ‘Table1 Email’ that evaluates whether the email exists in ‘Table2 Email’ (ie. the evaluation will results in TRUE/FALSE). From there in app builder, you can create a List that displays only emails where the evaluation is FALSE.
Here is an example I created in my account:
In Email1 Table I created a formula to check if the email exists in Email2 table:
After my table is set, I can go into App Builder and create a list that filters for emails that evaluated to FALSE:
As a result my list shows all emails that are in Email1 table but not Email2. Let me know if this helps!
