go get GitHub.com/emersion/go-imap
go get github.com/emersion/go-imap/client

client, err := imap.DialTLS(addr, nil)
if err != nil {
   log.Fatal(err)
}
defer client.Logout()

if err := client.Login(username, passWord); err != nil {
   log.Fatal(err)
}

defer client.Select(mailbox, false)

uids, err := client.Search(
   imap.NewSearchCriteria(
      imap.HeaderSubject("Your email subject"),
   ),
)

if err ! = nil {
   log.Fatal(err)
}

if len(uids) < = 0 {
   log.Fatalf("No email found")
}

uid := uids[0]

seqSet := new(imap.SeqSet)
seqSet.AddNum(uid)

if err := client.UidStore(seqSet, "+FLAGS.SILENT", imap.NewFlagSet(imap.DeletedFlag), nil); err != nil {
   log.Fatal(err)
}

if err := client.Expunge(nil); err ! = nil {
   log.Fatal(err)
}
