OpenEMM i newsletter, filtry spamowe Opcje

[hhg]

Obecnie korzystam z systemu do wysylania newsletter o nazwie OpenEMM. Podczas testow wyszlo ze na 5 skrzynek: gmail.com, interia.pl, op.pl, yahoo.pl, tlen.pl
tylko gmail.com odbiera wiadomosc, w reszcie gdzies sa gubione i sadze ze to filtry. A jak wiadomo filtry skanuja zawartosc prezsylki. Podejrzewam ze przede wszystkim patrza na naglowek takiego maila. Problem polega na tym ze chcialbym aby maile jednak wszedzie chodzily.. Co moge zrobic aby taka skutecznosc osiagnac?

Oto moj naglowek maila
