44
+ = How do I encode my emailaddress(es)? =
 
 
45
 
46
+ By default the option `Encode mailto links` is enabled and the default method is `JavaScript ASCII`. This means the following html snippet:
47
+ `<a href="mailto:myname@test.nl">My Email</a>`
48
+
49
+ Will be encoded, which creates the following output in the source code of your page:
50
+ `<script type="text/javascript">/*<![CDATA[*/ML="mo@k<insc:r.y=-Ehe a\">f/lMt";MI="4CB8HC77=D0C5HJ1>H563DB@:AF=D0C5HJ190<6C0A2JA7J;6HDBBJ5JHA=DI<B?0C5HDEI<B?0C5H4GCE";OT="";for(j=0;j<MI.length;j++){OT+=ML.charAt(MI.charCodeAt(j)-48);}document.write(OT);/*]]>*/</script><noscript>*protected email*</noscript>`
51
+
52
+ Therefore spambots are not able to scan this emailaddress from the site.
53
+
54
+ Within your posts, you can use the shortcode `[email_encode]`, f.e.:
55
+ `[email_encode email="myname@test.nl" display="My Email"]`

61
 
62

63
 
64
+ You could use add extra params to the mailto link and add `target='_blank'`, f.e.:
65
+ `[encode_email email="yourmail@test.nl" display="My Mail" extra_attrs="target='_blank'"]`
66
