What Is Email Whitelisting and Why Is It So Important?
By Jill Fanslau March 19, 2019
Want your emails to hit the inbox instead of the spam folder or promotions tab? Then you’ll want to read this post.
What if your emails never hit your subscribers’ inboxes? What if your messages always end up in their spam folders or promotions tabs instead?
It happens more than you might think. Luckily, there’s a super simple solution: email whitelisting.
What is an email whitelist?
Email whitelisting is when a subscriber adds your email address to their contacts list within their ISP, like Gmail or Yahoo!.
Think of your inbox like a door with two locks on it: a deadbolt and a doorknob. If one of them is locked, a message can’t get in.
AWeber works with the ISP to get all of our customers’ messages into the inbox. We essentially “unlock” the deadbolt for your messages.
However, we have no control over what happens on the individual level. Anyone that has an email account can set up their own filters, which locks the doorknob. Even though the deadbolt is open, your messages still can’t get in. Your emails may be sent straight to their spam folder or promotions tab.
That’s why whitelisting is so important. When your subscriber whitelists your email address, he or she unlatches the second lock for you, regardless of what filters they have activated. The door is open for your messages.
“When your customers whitelist your email address, it provides feedback to their provider that your mail is wanted,” said AWeber’s Director of Deliverability Karen Balle, who gives multi-million dollar companies advice on how to reach the inbox.
Getting subscribers to whitelist you can also increase your overall reputation with an ISP, according to Balle. “Since your message is delivered into your customer’s inbox, it helps increase reputation by increasing your read, open, and click rates as customers are more easily able to find and interact with your message,” she explained.
And the higher your engagement rates, the better your deliverability to all your subscribers (whether they whitelisted you or not!).
Whitelisting doesn’t mean you can spam your subscribers . . .
Being whitelisted isn’t a free pass, though. You can’t send your subscriber whatever you want, whenever you want. Once your whitelisted, the ISP will keep a close eye on your messaging behavior to make sure you practice responsible email marketing, and that you’re not violating the CAN-SPAM Act.
If you take advantage of your whitelist status by spamming your subscribers, your deliverability reputation with that ISP will suffer and hurt your results over the long haul.
How do you get subscribers to whitelist you?
Ask them. It’s that simple!
Here’s a quick example of what you can write. (Feel free to tweak it to match your brand’s voice and tone.)
Take this important step! To make sure you receive emails from me, add my email [enter your email address here] to your contacts list. By adding me, you ensure my messages, special offers, and invites make it into your primary inbox.
Below are some more examples of how to incorporate whitelisting instructions into your content.
In your Welcome email
What to Write is one of AWeber’s most popular free email marketing courses. It teaches you how to effectively write an automated email series — and also includes 45+ downloadable fill-in-the-blank templates. The very first email is a Welcome email that includes short whitelist instructions.
Ann Handley is a bestselling author and the chief content officer at Marketing Profs. Through AWeber, Handley sends out a long-form newsletter called TotalAnnarchy. Here’s the automated welcome email she sends when you subscribe. It can save her newsletter from hitting your Promotions tab.
When you subscribe to Scott’s Cheap Flights, you get email alerts for discounted international flights departing from airports near you. The very first email you’ll receive has easy-to-follow whitelisting instructions.
On your Thank You page
Another key location for your email whitelisting instructions is a Thank You page. If someone signs up for your emails or a course, you can offer up whitelisting instructions then. So we not only asked people to whitelist AWeber in our What to Write Welcome email, but we also did it on the Thank You page.
SEO mastermind and Backlinko founder Brian Dean also includes whitelisting instructions on his Thank You page. You can see them in the P.S. section below the screenshot of his AWeber confirmation email.
Stage One Startup reminds subscribers that their confirmation email may have landed in the promotions tab. They encourage you to drag it over to the primary tab to whitelist their email address.
How does a subscriber whitelist your email address?
It can vary depending on the ISP. Here are examples of some of the more popular clients that your subscribers might be using to receive emails. Under each section are steps on how to whitelist a sender’s email address inside that client.
Feel free to direct them to that article for the specifics on how they could process this in their own email client, so you don’t have to reinvent the wheel!
Whitelisting is only part of the equation
Keep in mind, while whitelisting can help you reach the inbox, you won’t stay there long if subscribers don’t like what they get from you. So keep striving for the most relevant, useful content possible!
