If you are a business that sends commercial or transactional emails, it’s critical to use both SPF and DKIM. Not only will these protocols protect your business from phishing and spoofing attacks, but SPF and DKIM ultimately help protect your customer relationships and brand reputation. However, these are only just a few of the many steps you can take to ensure business-critical emails reach your customers’ inboxes on time and don’t end up in spam folders.

Note: The problem with DKIM is that because it’s more difficult to implement, fewer senders have adopted it. This inconsistent adoption means that the absence of a DKIM signature does not necessarily indicate the email is fraudulent.

Adding a DKIM signature to your email’s header adds another layer of authenticity to your campaigns. DKIM, along with SPF and DMARC make up the dream team trio of email authentication and security. Together, they work in synergy to prevent email spoofing and make your emails more trustworthy.
