Do your customers complain that your emails go to their junk folder, or complain that they don't receive your emails at all? You may be blacklisted.
What does that mean? You are marked as a treat because someone may have wrote a program sending email spam from your company domain name (@company.com), or your website may be hosted on a shared web hosting server that has potential treating websites.
How do you check to see if the web server is blacklisted? Use an online tool like Email Blacklist Check. It will check many blacklist databases to see if the web server your hosting company put your website on is blacklisted.
If any of the databases says that web server ( your website live on) is LISTED, then you will definitely have problems sending and receiving emails from customers.
You may even be removed from some search engine indexes for being blacklisted. Why? Because a search engine wants to display good safe results. If a hosting company shows it does not minimize malicious activity from its customers, search engines will exclude the numerous malicious and non malicious websites of that IP address from its search engine index.
Being blacklisted is no fun. Here's how you can get off a blacklist:
Hopefully this will help solve some frustration and confusion.
