DKIM (DomainKeys Identified Mail) plays a key role in email marketing by providing authentication and verifying the integrity of emails. There is no doubt that email marketing is crucial to growing your business, but the effort will only pay off when the emails reach the primary inbox of the intended recipients. DKIM is one of the ways to help improve email deliverability and reputation by verifying the authenticity of the sender sending emails from your domain.
Why is DKIM important in email marketing?
DKIM verifies that senders using your domain are authentic. This helps recipients identify you as a legitimate sender, increasing subscriber trust and engagement. Not only that, DKIM deployment protects your buy bulk sms service business from email-based phishing and spoofing attacks that use your company’s name.
Improve email deliverability using DKIM
Your outgoing emails may land in spam folders or be rejected directly by the recipient's mailbox, making all your email marketing efforts fail. However, DKIM can ensure that your emails reach the audience. It uses a pair of digital signatures, public and private keys, to confirm that the email is sent by an authorized server. It also verifies that no part of the email, including attachments, has been modified or destroyed during transmission.
The entire process ensures that your emails reach your target audience’s inboxes instead of spam folders, increasing click-through and open rates. With increased engagement rates, more subscribers will pay attention to the Call to Action button or link, and many of them will even add the suggested products and services to their carts and finally check out!
Build brand trust with DKIM
If recipients' mailboxes consider your domain to be authentic, your email reputation and trustworthiness will be enhanced. According to Google's online resources, new senders who send emails to Gmail users must set up at least SPF or DKIM. Google performs spot checks on incoming mail and has observed that mail that lacks SPF and/or DKIM is rejected with a 5.7.26 error or classified as spam. This helps Gmail build trust in you as a sender, which in turn encourages recipients to view you as a reliable brand and has an impact on your broader digital marketing efforts.
Common Challenges of Implementing DKIM in Email Marketing
There are several challenges that an organization may face when implementing DKIM (DomainKeys Identified Mail) in email marketing. Here are some common challenges that may arise:
The complexity of the technology
Organizations with limited technical resources or expertise may find setting up DKIM a challenge. It requires knowledge and expertise in generating and managing DKIM keys, configuring DNS records, and integrating DKIM signing into the email sending infrastructure.
DNS Configuration
Implementing DKIM requires adding DNS records to your organization's domain name. This can be a daunting task for some organizations, especially those that have complex DNS configurations or have many domain names used to send email.
Email Deliverability Issues
Email deliverability can be improved by using DKIM, which verifies the authenticity of an email. However, if there are misconfigurations or mistakes when implementing DKIM, it can cause email delivery issues. For example, if DKIM signing is not set up properly, it can cause emails to be marked as spam or not accepted by the recipient's email server.
Managing DKIM keys
Managing DKIM keys can present challenges, especially in organizations that send large volumes of email or have multiple domains sending email. When implementing DKIM, it is important to carefully consider key rotation, storage, and the security of private keys.
Third-party integration
Integrating DKIM with third-party services is often complex. Email marketing agencies or service providers hired by an enterprise may offer varying levels of DKIM support or integration. Cooperation and coordination between the organization and the service provider is often necessary.
