Have you had your emails go into the recipient’s junk mail/SPAM folder?
Has Google blocked your emails?
Have you received SPAM emails from yourself or your colleagues?
If any of the above have happened to you, you should look at enabling DKIM signing for your emails.
What is DKIM?
DomainKeys Identified Mail (DKIM) is an email authentication method, and it can help prevent spammers and other entities from impersonating your domain.
How does DKIM work?
There are two parts to DKIM, the DKIM record that needs to be added where you manage your DNS and the DKIM header that will be included with all the emails sent from the domain.
DKIM uses digital signatures based on public key encryption to authenticate where an email comes from. A pair of encryption keys is used, a private key for the sender to sign the messages and a public key for the receiver to verify the authenticity of the sender. A receiver cannot use the public key to sign messages.
How can you enable DKIM for your domain?
That was quite a bit of technical language there, but how does one enable DKIM?
If your email is hosted with us, just reach out by opening a support ticket from your client area and you can request us to enable this for you. If we do not host your DNS we will provide the records that need to be added, you will just need to forward this information to whoever is managing your DNS.
In the case of your email not being hosted by us, you will need to get in touch with the people that do so that they can help you out. Open a ticket to us if your are not sure who your email provider is and we can let you know.
SPF and DKIM are great tools that work together with DMARC to prevent email SPAM and spoofing. Next month we will share an article about DMARC and how all these 3 records come together.
