Email is a critical tool for businesses, but it can also be a way for criminals to try and trick people. Luckily, there are three technologies that can help make email more secure: SPF, DKIM, and DMARC.
SPF (Sender Policy Framework), is like a security guard who checks people entering a building to see if they're allowed. Just like a security guard checks your ID before letting you in, SPF checks the sender to make sure they're authorized to send an email on behalf of a specific domain. If the sender isn't authorized (aka spoofing), SPF prevents the email from reaching the inbox.
DKIM (DomainKeys Identified Mail), is like a special invisible stamp that tells computers that a sender's email is real and hasn't been altered. When an email arrives, the computer verifies the stamp to make sure that it really came from that sender and that no one changed the contents of the email along the way.
DMARC (Domain-based Message Authentication, Reporting & Conformance), is like a rule book that tells computers exactly what to do whenever an email from a specific domain doesn't look right. When an email arrives, the computer checks if it's authorized and real using SPF and DKIM. If it doesn't look right, the computer checks the rule book (DMARC) to determine what to do. The rule book might say, "put the email into the spam folder" or "reject the email altogether." This helps keep maliious emails from reaching your eyes.
Every business should use SPF, DKIM, and DMARC because it helps keep their email safe. If you're a business owner, it's a good idea to hire a professional to help set up these technologies correctly. That way, you can be sure that your email is secure and that criminals can't fool your employees or customers.
A professional can help you set up SPF, DKIM, and DMARC so that they work together to provide the best protection for your business. They can also help you monitor your email traffic and adjust the settings if necessary. This way, you can focus on running your business and not worry about deliverability issues or risk caused by misconfiguration.
In conclusion, every business should use SPF, DKIM, and DMARC to protect their email. By hiring a professional to set it up correctly, you can be sure that your email is secure and that criminals can't fool you or your customers.
