DKIM (Domain Keys Identified Mail) is a standard email authentication method that adds a digital signature to outgoing messages. Receiving mail servers that get messages signed with DKIM can verify the sender’s identity, and ensure that messages actually came from the sender, not someone impersonating the sender.
In other words, it detects forgery and prevents the delivery of potentially harmful emails. So, it helps protect email senders and recipients from spam, spoofing, and phishing. Plus, it improves email deliverability, by reducing the chances of being blocked by the recipient’s servers or entering spam.
A DKIM signature is a header added to email messages, which contains specific values that allow receiving email servers to validate the source of the message.
For this, a pair of unique encrypted keys are used:
When these keys match, it means that the identity of the sender is valid.
Suppose you are using 123FormBuilder to collect data from your customers and use email notifications to communicate with your customers. In that case, DKIM can help you rest assured that your messages are delivered and trustworthy. Especially if you are choosing to personalize the email notifications and send them on behalf of your own custom domain (using a custom email address as sender or from email).
