Email Whitelisting

If you’re an email sender who wants their campaigns to reliably land in the inbox, or a recipient who would like to ensure that emails from a particular someone don’t get junked, it’s beneficial to understand how to whitelist email addresses.

Chapter 1

What is a whitelist?

Whitelisting is a quick, once-only task requires that the sender of an email is added to the email client’s “Address book” or “Safe senders list”, usually by opening an email message and verifying that the sender is to be trusted:

Here are simple instructions on how to ensure that future emails get delivered straight to the inbox, in some of the most popular email clients:

Apple Mail (OS X and iOS devices)

Both Apple Mail on OSX and Mail on iOS devices have a similar process for adding senders to Contacts. By selecting the From, or Reply-to on an email message, you can choose to “Add to Contacts”, or “Add to VIPs”. The advantage of “Add to VIPs” is that future emails from this sender will be added to a special VIP mailbox in iOS Mail.

Outlook 20xx

When opening an email from a sender, an alert at the header of the message, “Click here to download pictures…” should display. Click this and select, “Add Sender to Safe Senders list”:

Outlook.com

After opening an email message, an alert message should display with, “Parts of this message have been blocked for your safety.” Beneath this, click the link with, “I trust sender@theirdomain.com. Always show content”:

Yahoo! Mail

When opening an email message, a “+” symbol should display next to From: and the sender’s name. Select this and an “Add to contacts” pop-up should appear. Select “Save”:

Gmail (Webmail and mobile)

Getting all future emails from a sender to appear in the “Primary” tab (instead of “Promotions”, or elsewhere) is a quick, two-step process. First of all, drag-and-drop the email message from beneath the tab it’s currently filed under, to the “Primary” tab:

Once done, a message alert will appear with, “This conversation has been moved to Primary. Do this for all future messages from sender@theirdomain.com?”. Select “Yes”:

Gmail on mobile devices doesn’t provide a way to prioritize messages. However, touching “Show images”, then “Always show images from Sender” will ensure that images always display in the inbox:

Android (Default client)

On Android devices, open the email message and touch the picture of the sender that displays before the message. Touch “Add to Contacts”.

Windows Live Desktop

After opening an email message in Windows Live Desktop, an alert in the preview pane with, “Some images in this message are not shown.” will display. Select the link, “Add to Safe Senders list”.

AOL Mail

In the preview pane for an opened email message in AOL Mail, select the sender’s From name under the email’s subject line and select “Add Contact” from the drop-down menu:

Linking to these instructions

Many email senders link to whitelist instructions from their email campaigns, to ensure that their campaigns are delivered straight to the inbox for as many recipients as possible. A common approach is to add a short message to your email content, like, “To keep receiving emails from us, please add us to your address book”. Here’s code you can use to link to this guide from your email newsletter:
