How do you validate email in power automate, that this is valid email and that the email is the same as from the one from SharePoint list.
There are not enough details and I am not sure what the question is.
1. Are you asking if its a legitimately Formatted email, or as you asking if Power Automate can do a LookUp on a DNS server to find the Host for the SMTP/Exchange, whatever server and then tell you if its legit?
No it cannot do that, unless you want to make an HTTP call yourself to try to verify it but trust me dont
2. If you want to verify if the email exists in the List do this
a) add a Get Items SharePoint
set the filter to like
EmailColumn eq EmailToCheck
b) do a condition check to see if the length of the body/value = 1
If yes, then in the yes section, do whatever it is you wanted to do
If no, then you know the email isn't in the list and do whatever you want
If I have helped you, I would really appreciate if you please Mark my answer as Resolved/Answered, and give it a thumbs up, so it can help others
Cheers
