I am using emailonacid to test inboxing across different email clients. It seems extremely difficult using their tests to inbox an email to outlook 7 or 10 email clients. I have gotten creatives without any links to inbox, but any link thrown in and it fails their test. I have tried removing all junk words, replacing letters with similar symbols, and I've also tried adding lots of junk text. Does anyone have experience passing these tests with an ad message? Or is anything with a link automatically junkboxed? Does outlook look at senderscores or senderbase? Thanks for anyone who can help.
