If you’re starting to send marketing emails, or just want to dive deeper into the tech side of the authentication protocols, one day you may be questioning yourself, “what is DKIM?”. We’ve got a simple explanation for you: DKIM (which is an abbreviation for Domain Keys Identified Mail) is a security method helping prove an email was really sent by the domain it states it comes from, and has not been altered on its way to someone’s mailbox. It is kind of a digital signature added to every email, so receiving mail servers can check if the message is genuine.
So, if someone asks you, what is DKIM in email or what is a DKIM, you can answer that it’s basically a tool that tells inbox providers, “This email is safe and truly from us.” It helps build trust with email services like Gmail or Outlook and helps avoid spam folders.
Setting up DKIM (along with SPF, DMARC, and BIMI) positively impacts your email deliverability, strengthens your domain’s reputation, and shows inbox service providers that your messages are authentic and credible.
DKIM is an essential part of email authentication and a key step toward keeping your emails secure and properly delivered.
