In fact, one of my email addresses that normally receives emails from Aweber did not receive my last three Aweber broadcasts. And open rate is down about 35 to 40% or so.
So I looked up the servers that sent the Aweber emails and it turns out they're on a blacklist.
I got a Spamcop positive and also Squid Malicious.
I checked on sites like:
Email Blacklist Check - See if your server is blacklisted
MailBoxTools.com | 5 Second Email Blacklist Check - Is your email server or IP blacklisted?
I found the Aweber email servers by opening up my Gmail account and clicking on the "Show Original" by the reply button options in Gmail.
Here's an example:
Received: from smtp-soi-g03-106.aweber.com ([22.214.171.124]:35981)
You can look up:
This particular IP is not from one of my own Aweber emails but from another business that uses Aweber.
But I found his IP address also comes up with the Squid Malicious spam listing.
So if you find your open rates, clickthroughs and most importantly sales going down with Aweber then look up your emails and see if your Aweber server is blacklisted as well.
Please let me know if you've been experiencing similar problems.
I've contacted Aweber this weekend and they are looking into it for me. But in the meantime my email broadcasting ability has been seriously compromised.
