When I'm sending the Email id using the HTML. It is visible in browser G-mail but it is not visible in the Outlook and Apple Email client. This is a sendgrid email template.
<div style="font-size: 10px; line-height: 150%; margin: 0px; text-align: left;">
<span style="color:#FFFFFF;">
<span style="font-family:arial,helvetica,sans-serif; decoration:none;" href="mailto: :useremail">
Sender Email::useremail
</span>
</span>
</div>
You can use this :-
<div style="font-size: 10px; line-height: 150%; margin: 0px; text-align: left;"><a target="_blank" style="font-size: 10px; line-height: 150%; text-align: left; color:#FFFFFF; font-family:arial,helvetica,sans-serif; text-decoration:none;" href="mailto: :useremail">Sender Email: :useremail</a></div>
