Spam messages are not anyone's favorite. However, to defend those companies, they send them to inform potential customers about their clients. Over time bots have changed how most people and companies send email marketing messages to you. With these bots, companies send emails while impersonating themselves as one of your friends or relatives. When this happens, you are likely to click on the links in the emails.

So, how do you avoid someone impersonating you and sending emails to your friends? The DKIM signature, the SPF, or DMARC is one of the most popular verification methods you send the email message.

So what is DKIM email, and how do you use it.

Why use DKIM?

You may think that DKIM email signatures are not critical and that it is just a slight personification. However, if someone spoofs your email, then you would understand how dire this can get. What is spoofing, you ask? It changes the content message in your email to something else by a different sender and makes it look authentic.

For example, if you are about to submit a significant proposal to your boss. You present it and think that it is gone. You hear no response. You assume that they are too busy to reply. You get a suspension, or worse, you get fired or find them very angry that you did not submit the proposal. You may have evidence that you sent it, but there is no proof that it got to the recipient.

The main objective of DKIM is to curb spoofing. Spoofing is a fraud, and it should not happen to anyone. DKIM will save you from such a circumstance.

What is DKIM?

DKIM is initial for DomainKeys Identified Mail. It is a digital signature that a person adds to appear on every email they send from a particular email address.

You may think that it is the regular signature that one sees at the bottom of the email. On the contrary, a DKIM signature is a random set of hidden characters in the HTML code of an email. It is usually in a place where no one would think of looking. Even so, incoming email servers will see the signature and verify authenticity. DKIM ascertains originality.

Once it receives a message, the incoming email server will check briefly, and if it detects no monkey business, it will display the message to the recipient. It is essential to note that DKIM doesn't particularly assure email delivery, but it certainly is better to be safe.

Additionally, one does not need to write the signature. It happens automatically once the DKIM configures your domain.

How does the DKIM email signature work?

  1. There are several options. The first thing is that the sender has to decide what their DKIM will comprise and where they want to place it. The header can also be in the email body.

  2. The next step is creating the DKIM, and later a message that has the signature is sent.

  3. The last step is, when the message is sent, the recipient server authenticates the message by crosschecking the DKIM signature. Again, if the recipient suspects that there is no match in the keys, then there is a possibility that the message delivery will fail.
