You can maximize their deliverability by using DKIM record generator tools to add a DKIM signature to marketing emails. Email phishing and spoofing are the two most prevalent types of cyberattacks. According to a report by Statista, these account for 54% of cyber vulnerabilities. According to another cyber attack statistic from Proofpoint, fraudsters send 3,1 billion domain spoofing emails daily.
The solution is for an email server to authenticate incoming emails using encrypted cryptographic keys. DKIM signature is the best technology that functions globally. If you’re a digital marketer for a business, read this article to the conclusion to learn about the best DKIM record generator tools and the basics of DKIM. In addition, if you only use emails for personal purposes and want to avoid phishing and spoofing attacks, this article will assist you by providing basic knowledge.
What’s DKIM Record?
DKIM is a technology for verifying email senders known as DomainKeys Identified Mail. Using DKIM, the recipient’s server validates the email’s origin and integrity. In DKIM, a DKIM signature is added to the email’s source code. You configure it in your email service client app and instruct it to add the signature as a header message to all emails you send from your email domain. In addition, the email app encrypts the signature using cryptography.
Now, the recipient email server deciphers the cryptographic encryption and reads the signature using a key (public key). These key and additional DKIM texts are collectively called DKIM records. The DKIM record cannot be viewed or read in the modern view of an email. To view the DKIM record, you must select the Show Original option from the menu of an email accessed through Gmail. Other email apps include a comparable option in their email apps.
Initially, the following will appear in the Original message of an email.
DKIM: 'PASS' with domain abc.comSecond, you can find the “DKIM-Signature:” text in the Original message by scrolling down. It begins the DKIM record and contains the alphabetical tags listed below.
v=1: the DKIM versiona= the signing algorithmc= a standardization algorithm for DKIM record body and headerd= DKIM signing domains= DKIM selectort= timestamp of email signingbh= hashed email bodyh= header listb= the digital signature 
More than a few lines of code is required to create a DKIM record. DKIM record generator tools are those that must be used. These tools are also efficient, as you can create thousands of DKIM signatures in minutes.
How To Create DKIM Record?
DKIM record is essential for marketing and business emails because the majority of companies email servers prohibit non-DKIM emails. Even if you send emails to personal users, you must use a DKIM record because email providers such as Gmail, Outlook, Yahoo, etc., block or send non-DKIM emails to the spam folder. Here’s a step-by-step guide on how to create a DKIM record using any of the DKIM record generator tools listed later in this article.
- Visit one of the listed DKIM record generator tools.
- Most tools will require you to enter the following information: Selector, Domain, and Key Length.
- Enter the domain name in a straightforward format, such as abc.com. Avoid including the https:// tag.
- To use Selector, enter any name, such as coffee, tea, mobile devices, marketing, etc. You should save the name for subsequent use as a DKIM selector.
- Choose a key length from the available options, such as 1024, 2048, 4096, etc.
- Click Generate to proceed.
- The tool will show you DKIM data in two sections in a short while.
- The record value is the primary DKIM record section.
- The Private key and Public key are shown in the Key section.
DKIM Record Benefits
- It aids the email server in determining whether the email has been tampered with since it left the sender’s server.
- The DKIM record authenticates the domain of the email originator. If you receive a payment link from a vendor whose DKIM does not match, you should not use the link to make payments.
- If you use AMP email tools to create dynamic marketing emails, all outbound emails must be signed with a DKIM record; otherwise, Gmail, Yahoo, etc., will not accept AMP emails.
- DKIM requires cryptographic checksums for each email, which is computationally intensive. As a result, fraudsters cannot send mass fraudulent emails using DKIM technology because it is too costly.
What’s DKIM Selector?
DKIM selector is a crucial element of the DKIM record for your email. It permits the use of multiple DKIM keys on the domain name of an email message. When the incoming email server detects a DKIM signature in an email header, it begins searching the DNS for the email’s public key to validate it. The DKIM selector tells the server where to find the public key. The DKIM selector is also connected to the private key with which the public key corresponds to guarantee authenticity.
This Selector can be located using the S-tag in the DKIM record. For example, Google used DKIM selector 20210112 to send a marketing email from the YouTube.com domain in the preceding DKIM record example. The basics of a DKIM record, its components, and how to create one have all been covered up to this point. Now is the time to learn about popular and trustworthy DKIM record generator tools for email marketing campaigns.
