Need help - email I send out are being classed as spam

If I were you I will try to do this to figure out what is going on:
1) create 3 new email accounts with the domains that are rejecting your emails.
2) send emails to each of them
3) check if they are still "spam"
4) Call/email their support team and find out what is going on

Server-side SPAM detectors look for certain red flags to determine whether or not messages are bulk mail. Based on your description of the situation, your wounds appear to be largely self-inflicted. You sent out a large number of emails from offshore IP-addresses, presumably using a domestic email address. Those are three very large red flags. If your messages were composed largely of graphic images rather than text, then you raised a fourth red flag. You may also be using an email provider that is popular among SPAMmers. That would be a fifth red flag.

The one thing that is a bit unusual in your case is that it seems that it was your recipients' email clients that flagged your messages as SPAM. If you had been in their address books, then maybe this would not have happened.

In the future, you may save yourself lots of grief downstream if you use your provider's webmail client.

 

I don't know your situation, so I can only share mine and maybe it will give you some ideas. I used to have pretty much all of my email rejected by ISP's, and even people who had me whitelisted would not get email. This was caused because I was using a mail server that a lot of other people were using (through the company that hosts my websites).

The solution that worked for me was to simply change my outgoing server to my internet provider instead of the company that hosts my email accounts. For example, I changed from xxx.dreamhost.com to xxx.cox.com. Never have lost a single email since.

I hope your solution is as simple as mine was (though it took me a LONG time to figure it out).
