Can I use a formula URL button to create an email using an email client and redirect to the initial report?

I'm trying to make it easier for my CRM users to research a lead and email a lead so I'm providing URL buttons to enable a google search or a mailto: link.  I'm also trying to track the activity to provide a report to their managers so I need to 1) edit the record, 2) open the email and then 3) redirect back to the original report.  I'm struggling to get the third re-direct to work. 

Code is below

var text weblink = "http://www.website.com";

var number NewToggleValue = If ([Email toggle]=true,0,1);

var text URLONE = URLRoot() & "db/" & Dbid()
& "?act=API_EditRecord&key=" & [Record ID#]
& "&_fid_419=$NewToggleValue"&"&apptoken=aaaaaaaaaaaaaaaaaaaaaaaaaa";

var text URLTWO = "mailto:"&[email address]&";"&[Sales Rep for Leads - Email Address (P)]&";"&[Sales Rep for Leads - Email Address (S)]&"?subject=Your inquiry about ..." &"&body=Hello,%0A%0AThank you for your interest in ...  I?m ... ? the sales representative in your area.  My contact details are below.   If there is anything I can do to help with your project, please don?t hestitate to contact me.   %0A%0AThank you.  %0A?"&"{insert name here}"&"%0A"&"{and email here}"&"%0A... You may personalize the message by modifying this text.%0A"&"%0APlease click the link below to learn more: %0A" &$weblink;

var text URLTHREE = URLRoot() & "db/" & Dbid() & "?a=q&qid=153";

"<a href="& $URLONE & "&rdr="& URLEncode($URLTWO) &URLEncode("&rdr="& URLEncode($URLTHREE))&"'><img   src=\"https://images.quickbase.com/si/32/016-email_0.png\"></a>";
