Email Authentication: A Powerful Way to Help Get your Emails into the Inbox with DKIM

Getting into the inbox is the foundation of successful email marketing. You can spend hours crafting the perfect message, but if it goes to the spam folder, your subscriber won’t see it. 

Mailbox providers (Gmail, Yahoo, and others) are always looking for ways to make the email they place in their customers’ inboxes more relevant. With the ever-increasing amount of emails being sent each day, the filters and systems they have in place are more advanced than ever, and are evolving continuously.


To get into the inbox, you first need to follow fundamental email deliverability best practices:

  • Only send email to people who have asked to receive it.
  • Make your content relevant, well-designed, and engaging.
  • Don’t send people content they are not expecting.
  • Don’t send more email to a person than they can easily read, and don’t send so little that they forget about you.

If you have these best practices covered, then read on to find out how to supercharge your emails’ performance with DKIM.

Making your emails stand out

Imagine a large, fast-flowing river. It’s autumn, so there are leaves floating down the river. I ask you to jump into the river and get me a leaf with my name written on it that fell from a specific tree. Now imagine that there are billions of leaves in the river.

This is like what mailbox providers do every day to place emails into their customers’ inboxes.

Given this, when mailbox providers receive a message they attempt to identify who sent it, which allows them to treat emails from them as a group. Note, though, that doesn’t guarantee that every email will have the exact same outcome.

This identification goes beyond just looking at the sending email address; behind the scenes there are email authentication standards in use that senders can take advantage of to ensure that their emails are grouped correctly and that they stand out from the crowd.

Giving your emails authentication superpowers
