Yeeesss, the Spam/Trash folder is no longer so boring!
Finally, the spammers are now using all the features of the email clients and have made the subjects to look much nicer.
Do you know how they do that?
They add UTF8 characters in the subject and then they encode the entire string using Quoted-Printable encoding:
Content-Type: text/html; charset="utf-8" Content-Transfer-Encoding: quoted-printable Subject: =?utf-8?q?=F0=9F=91=B6_Free_Trial_of_Diapers_from_The_Honest_Company_?= =?utf-8?b?8J+Rtg==?= This is the output:
Content-Type: text/html; charset="utf-8" Content-Transfer-Encoding: quoted-printable Subject: =?utf-8?b?8J+YqCBXaWZlIFdhbGtlZCBJbiAtIE9PUHMhISEhISDwn5io?=
