The first thing to note is that it is becoming more and more common for ISPs to incorporate email authentication
without the need for companies or individuals to invest in additional applications or protective software.
If you want your email or newsletter to land in an inbox and not spam, it is a good idea to consider setting it up.
And you don’t need to have another authentication method already in place to set DKIM up.
But there are additional advantages to setting up DKIM:
Firstly, while SPF is an excellent email authentication method, DKIM is a set above as it relies on encryption methodology and not just IP. You learn more about your company’s DNS records and provide more protection for both you and your prospects from spoofing and spam.
It also helps you keep track of information. Due to the tracking being through a digital signature which is part of the email header, information is not lost when emails are forwarded. Your authentication method thus remains consistent and visible every time it's forwarded. And it will continue to avoid falling into spam as a result, too.
DKIM also prevents spammers from changing the source addresses of your message. While it does not filter or identify spam, it still protects you and your prospects from spoofing and spam.
There are some limitations to keep in mind, of course. Mainly, it cannot provide instructions to email servers and ISPs
about how to treat an incoming email if the authentication checks aren’t verified satisfactorily.
For that, and to further improve your deliverability, you need to look into setting up DMARC
Regardless, if you’re sending out many emails or newsletters in 2023, and you want to:
- Protect your prospects from spam.
- Protect yourself from spoofing.
- Land in the inbox instead of spam.
- Be competitive in the world of cold email and newsletters.
You need to have at least
one email authentication method set up. And you don’t need to bug your IT team to do so – it is straightforward to do so yourself!
