After you understand why ISPs block some emails and how to avoid the problems, you will be able to improve your email deliverability and increase your email open rate. So, why do emails get blocked or filtered?

As you probably guess the main reason why the emails are filtered is spammy looking content. You will absolutely recognize spam emails at first sight: unknown email address in the From field, misspelled Subject, Subject lines written in ALL CAPS, large and often bold font size, pure promotional and sales content. Furthermore, have you ever paid attention to the links you use in your emails? You may think why you should care about the links if they are from your own domain. I thought the same until the recent time when I discovered that the links may be a cause of email blocking.

If your email message contains links from blocked domains, you have a “chance” to get it filtered or blocked. Here is a live example from my own experience. I registered the glockeasymail.com domain 2 years ago but didn’t use it until the recent time. There was only an open source directory link exchange script installed.

Some time ago I received an email from PayPal telling that glockeasymail.com was probably hacked and used by spammers to send their PayPal fishing emails. I addressed this issue immediately, removed a hacked directory link exchange script from the site and removed all the scripts uploaded by scammers. It seemed the problem was solved.

In fact, it wasn’t. A few weeks ago I sent an email campaign to my customers. The email contained a link from the glockeasymail. Autocad Lt Mac Download Crack For Idm. com domain. The majority of emails were sent successfully. As always, I ran the Bounce Handler in EasyMail7 to process bounces.

I found that a couple of dozens of emails were blocked by Barracuda and FortiGuard spam filters and returned. The reason was “Spam Content”. That was strange because the email didn’t have any signs of spam. I thought the problem might be in the message format (I sent a HTML email). I changed the message format to plain text and re-sent the email to those customers who didn’t get it.

The emails were filtered as spam again. I decided to send a short message to those customers asking them to provide me with a different email address. The short email didn’t contain any links and was delivered successfully.

This made me think that the problem might be in the URL I included into my original message and, in particular, in the domain the URL was from. As the domain was used by spammers some time, it may be blacklisted and that’s why some filters block the email as spam. Keeping this in mind I replaced the original link with a redirect link from our main glocksoft.com domain and re-sent the message.

This time the emails passed through the filters and reached the recipients. So, if you find your emails blocked by the spam filters, it may be because of a domain name you use in the message content. A quick solution is to use a redirect method like I did. In the perspective you’ll need to contact the ISPs or spam filters developers to solve the problem with your domain block. Talking about links in the email body, not only the domain may be a cause of the email blocking or filtering. After analyzing bounced emails I discovered that some anti-spam filters didn’t like the recipient’s email address embedded into the URL.
