DMARC, DKIM and SPF What are they and why do they matter?
Every day, an estimated 376 billion emails are sent and received around the world.
Email is still one of the most important ways businesses communicate. Unfortunately, it is also one of the easiest ways for scammers to pretend to be someone they are not.
Imagine one of your customers receives an invoice that looks like it came from you. Your logo is there, the wording feels right, and nothing seems unusual. They pay it straight away, only to find out later the email was fake and the money went to a scammer.
If you have ever received an email that looked like it came from a supplier, a colleague, or even your own business but did not feel quite right, you may have already seen how easily this can happen.
DMARC, DKIM and SPF help solve this.
Put simply, they help prove that emails sent from your business are genuine and stop cybercriminals from sending fake emails using your business name.
SPF controls which email systems are allowed to send emails on behalf of your business.
DKIM adds a digital signature so the email cannot be changed after it is sent.
DMARC brings it all together and tells email providers what to do if something looks suspicious.
Here is the technical version translated to plain English for consumption.
When these protections are not in place, scammers and cybercriminals can impersonate your business and your real emails may even start landing in junk folders.
For businesses, this is not about technical configuration. It’s about brand reputation and trust.
Having DMARC, DKIM and SPF set up properly helps protect your reputation, keeps customers and staff safe from email scams, and ensures your emails are delivered and trusted.
