Getting your message opened and read is foundational to the success of your email marketing programs, which is why whitelisting is an essential part of a strong email strategy. Your messages might contain the most amazing content in the world, but if they never make it into your recipients’ inbox, all that work is for nothing. When your audience doesn’t receive your emails, it’s bad for business, because your conversion rates will suffer. And if they identify your emails as spam, it’s even worse – and your entire organization may have to deal with the consequences.

How to Whitelist an Email

Becoming a safe sender in the eyes of your customers and prospects is an excellent strategy. If your From address has been added to their contact list, whitelist, or address book, you become a safe sender.  And most email clients make it possible for recipients to automatically display images when an email is from a safe sender. But in order to do that, you need to make it clear to your recipients why your brand deserves to achieve that status, as well as what they need to do in order to make that happen. Here are whitelisting tips to help you make it happen.

How to Whitelist an Email: Become a Safe Sender

The best way to make sure your email messages get through is to have your recipients add your “From” address to their contacts or safe senders list. That tells their email client that they’re willing to receive email from you. This practice is called whitelisting, and it’s a way to identify that certain email addresses or IP addresses are sending mail that is wanted. It’s also a good reason to use the same From address consistently, so your recipients don’t have to add your organization as a safe sender multiple times. If you send messages from five different email addresses, only the ones that have been added to their contact list may make it through.

Ask your email subscribers to whitelist your email right up front – when they opt in, for example. Make the request periodically as well. But don’t just ask to be whitelisted – make sure you’re clear about the value of what your recipients are getting and what they’ll miss out on if the messages go to the bulk folder or spam jail.

You can also include reminders in your email message, but don’t ask in the preheader – save that real estate for messaging that will help get your email opened. Instead, include your whitelist email request in a sidebar or in the footer so it’s easy to access but not front and center.

Instructions for Whitelisting

In order to cover your bases with your recipients, you’ll want to include instructions on how to whitelist your email for the major email clients. You can get a current tally of the most popular clients from Litmus Email Client Market Share.  Remember, this is a moving target; it’s a list that’s changing all the time. Plus, nearly 60% of US consumers own smartphones, and Forrester forecasts that smartphone adoption will reach nearly 2 billion users around the globe by the end of 2015. So if your recipients are using mobile email, you’ll want to take that into account.

The thing is, it’s critical to look at your email list (and segments of that list) to understand what your audience needs.

  • Which email clients do they use?
  • Are they reading their email on a mobile device or a desktop PC?
  • Which operating system are they using?

Ideally, you would use dynamic content to provide the instructions (or a link to them) based on the email client your recipient is using most – because as we all know, our reading habits change depending on whether we’re at work, at home, or on the go.

Here are the instructions for getting your From email address added to contacts for several major email clients. It’s by no means exhaustive, and of course, these things change over time, so if you’re planning to include instructions (or link to them) in your emails or landing pages, be sure to check the source first.

Additional Tips

You’ll want to avoid using odd-looking From email addresses that look like they came from a robot, such as [email protected], or something that’s likely to be caught in a spam filter like [email protected] Your sender name should be easy to recognize – and easy to trust.

If you decide to use a person’s name, that person should be a real human being (or at the very least, a well-known robot), and they should be someone the reader would actually care about, like the CEO of your company or an industry expert. Keep in mind, we’re talking about marketing emails here. Sales emails, which generally come directly from a real person, are a different story.

And be sure to test various combinations by sending messages to yourself using the major email services to make sure your emails are being delivered correctly before you send to your entire list.
