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:
Another example:
Content-Type: text/html; charset="utf-8" Content-Transfer-Encoding: quoted-printable Subject: =?utf-8?b?8J+YqCBXaWZlIFdhbGtlZCBJbiAtIE9PUHMhISEhISDwn5io?=
