How to retrieve user login name using user email id in Nintex workflow?

I suspect you need to look at the Call Web Service action, pointing at the user profile service on the server. I haven't actually done this myself, so i'm afraid I don't have a working example, but it might give you a place to start looking...

You can use the Call Web Service action, in conjunction with the SharePoint REST API, to retrieve information about a site user given a user's email address. The SharePoint User resource (described at https://msdn.microsoft.com/en-us/library/office/dn531432(v=office.15).aspx ) details how to retrieve a user by email address, using the GetByEmail method.

For example, to get a user by email address, call the following REST method, replacing {{Endpoint}} with the SharePoint site collection or site from which to get the user and user%40domain.com with the HTTP-encoded email address of the user.
{{Endpoint}}/_api/web/siteusers/getbyemail(@v)?@v='user%40domain.com'

The SharePoint REST API docs provide several examples that allow you to get user information by login name, user ID, email address, and so on.

Hey Balaji Sampat​, do you mean you are trying to get the DOMAIN\USERNAME  ?  and you have the user.name@domain.com

try using set variable action

set: account name variable

equals: user profiles

source: account name as login name

when account name

equals: workflow data - the email address saved in a variable

hope this helps
