You may or may not be wondering what DKIM and SPF DNS records are and why they are important. In short, these 2 records provide validity to your email address and help to ensure your messages land in someone's inbox and not in spam / junk folders.
DKIM stands for DomainKeys Identified Mail. A DKIM record needs to be created for each domain you send email from and this ensures that emails are not altered in transit between the sending and receiving servers. The receiving server is able to look at and verify your DKIM record to determine that your emails are not junk / spam.
SPF stands for Sender Policy Framework. Setting up an SPF record helps to prevent malicious persons from using your domain to send unauthorized (malicious) emails, also called email spoofing. The SPF protocol is used as one of the standard methods to fight against spam. Some email recipients strictly require SPF. If you haven’t published an SPF record for your domain, your email can be marked as spam or even worse the email will bounce. If an email is sent through an unauthorized mail server, the email can be marked as spam. Having a properly set up SPF record will improve your email deliverability and will help to protect your domain against malicious emails sent on behalf of your domain.
