Black is a classic fashion look that pretty much everyone looks good in. However, as a marketer, black, as in being blacklisted, isn’t a color you want to find your emails dressed in.
After you’ve put all that time and hard work into an email campaign, the last thing you want to discover is that your emails aren’t reaching the target audience because you’ve been blacklisted. Let’s take a few minutes to dive into what blacklists are, what to do if you ever find yourself on one, and how to avoid them in the first place.
Blacklist: The Blackhole Syndrom for Emails
An email blacklist is a real-time review of emails by ISPs to determine if an email that is coming through could be considered as spam. The goal is to minimize the number of spam emails that reach their email users. Each ISP manages their own list, so you may find yourself on one or multiple at any time.
People, countries, companies and other entities that are deemed to be untrustworthy could find themselves on a blacklist without warning. ISPs are focused on preventing fraud and protecting their users, so if an email displays any suspicious signs or characteristics, that sender will be added to the ISPs blacklist and all emails from that sender will be dropped immediately.
As with most things, there is an opposite to blacklists and that, not surprisingly, is known as a whitelist. This is the list you want to stay one as all senders on this list will have their email delivered to their targeted end users.
From Blacklist to Whitelist
Should the worst case scenario occur and you find yourself blacklisted, don’t despair…it will take some effort, but you can rectify the situation. Typically you’ll receive notification that you have been blacklisted with specific instructions. However, that’s not always the case. Since one of the top reasons companies get blacklisted is due to being marked as ‘spam’ by end users, it’s not a bad idea to add an email delivery audit to your end of month reporting processes.
