Email Marketing terms


DomainKeys Identified Mail. An email authentication method designed to detect email spoofing.

What is a DKIM in email marketing?

DKIM, or DomainKeys Identified Mail, is an email authentication method that allows the receiver to check if the email was actually sent by the domain it claims to be sent from and if the content was tampered with during transit. It is a technique used to protect email senders and recipients from spam, phishing, and other email-based scams.

In email marketing, DKIM is crucial as it helps in building a good sender reputation and improves email deliverability. When an email is DKIM authenticated, it is more likely to bypass spam filters and reach the recipient's inbox. This is because ISPs (Internet Service Providers) trust that the email is genuinely from the sender, and hasn't been modified during transit. Therefore, DKIM plays a significant role in ensuring the effectiveness of email marketing campaigns.

How does DKIM impact email marketing campaigns?

DomainKeys Identified Mail (DKIM) significantly impacts email marketing campaigns by enhancing the deliverability of emails. It is an email authentication method that allows the receiving server to check if the email was actually sent by the domain it claims to be sent from and if the content was tampered with during transit. This helps in reducing the chances of emails being marked as spam, thus ensuring that marketing emails reach the intended recipient's inbox.

Moreover, DKIM builds trust with Internet Service Providers (ISPs) as it verifies the sender's identity, reducing the likelihood of phishing scams. This trust can improve the sender's reputation, leading to higher email deliverability rates. Therefore, DKIM is crucial for email marketing campaigns as it not only improves email deliverability but also enhances the sender's credibility and reputation.

Why is DKIM important in email marketing?

DKIM (DomainKeys Identified Mail) is crucial in email marketing as it adds an authentication layer to the emails, ensuring that the email content is trustworthy and hasn't been tampered with during transit. It works by adding a digital signature to the headers of an email message, which is then validated by the recipient's server using the sender's public key. This process helps in verifying that the email is indeed from the sender it claims to be from and that it has not been modified during transmission.

Moreover, DKIM significantly reduces the chances of an email being marked as spam or phishing, thereby increasing the deliverability rate of marketing emails. It builds a positive sender reputation and improves the likelihood of emails reaching the recipient's inbox rather than the spam folder. Therefore, DKIM is a vital tool for email marketers to ensure their messages are delivered and trusted by recipients.

How to set up DKIM for email marketing?

Setting up DomainKeys Identified Mail (DKIM) for email marketing involves a few steps. First, you need to generate a DKIM key. This can be done through your hosting provider or a third-party tool. The key consists of two parts: a private key that stays on your server, and a public key that gets published to your domain's DNS records.

Once the key is generated, you need to add it to your DNS records. This is usually done through your hosting provider's control panel. You'll need to create a new TXT record, enter the DKIM selector (usually something like "dkim._domainkey"), and paste the public key into the value field. After the DNS record is saved, it may take some time to propagate. Finally, you need to configure your email marketing software to sign outgoing emails with the private key. This process varies depending on the software you're using, but it usually involves pasting the private key into a specific field in the software's settings.
