question Anything Like the Perfect AntiSpam Outbound Mail

[Reyginus]

Tried switching to Gmass but failed their outbound tests. I tried over twenty times and failed. All messages were directly going into spam.

I changed everything changeable. Did all that was asked but still go same result. Checked if my mail was reported for spam or banned, nothing of sort.

It got me wondering. How do we overcome the spambox? Is there any perfect mail format that meets the right requirements? Is it about the keywords in the mails? Or is it that Gmass, Streak, etc., can't be trusted with correct data? What exactly are the likely problems?

Is it about the keywords in the mails?

this is one of them
message that looks like so commercial, get higher chance going to spam box

i am suggesting
-send the email message manually, one by one
-wait few hours between sending another message
-use different subject & message, specially the subject

Thanks but sending to over 4500 endusers one by one is tasking. I used to brag when I did 400 but this is huge stuff.
