Answer 1

It is the basic thing there is the difference between get_field and the_field.

the_field print the data and get_field required echo to print the value. Assuming the meta key name is Email. Use below code

  <?php 
if(get_field('Email')!=""){
    $mail = get_field('Email');
   echo '<a href="mailto:'.$mail.'"><i class="fa fa-envelope-o fa-2x"></i></a>'; 
}
?>

Answer 2

I don't quite get the question but can you try:

<?php 
if((the_field('Email'))!=""){
    $mail = the_field('Email');
   echo '<a href="mailto:'.$mail.'"><i class="fa fa-envelope-o fa-2x">'.$mail.'</i></a>'; 
}
?>

Answer 3

如我所见，the_field是一个函数，此函数返回一个邮件字符，因此有关the_fileld（'email'）的返回值为Null，我认为这意味着您的问题出在此函数中。
