Just show Email field

Not possible at the moment but your not the first person to request this so there is a high probability that it’ll be a feature in the next upgrade.

I vote for this also!!! This question beeing 7 months old, and nothing has happened around the issue. I won’t hold my breath waiting!!!! Any hopes for tomorrow then?

I was able to do this by doing the following:

Turn off First/Last name and phone (shortcode [easy_sign_up fnln=0 phone=0]

This will show only the Name & Email, however the Name field is still there. You can modify lib/esu-front-end-class.php to remove the field.

Find the following section:

if($fnln == true ) :
				unset($options['n']);
			else:
				unset($options['fn']);
				unset($options['ln']);
			endif;

Replace with:

if($fnln == true ) :
				unset($options['n']);
			else:
				unset($options['n']); // added to remove name field
				unset($options['fn']);
				unset($options['ln']);
			endif;
