There is nothing more frustrating than not been able to send emails correctly. You want to reach to clients with new offers, contact suppliers for additional materials, inside the company communication, and all with problems! What you need is to fix all the issues and missing configurations. Ensure email delivery with DNS SPF record and a few more DNS record types.
What is the DNS SPF record?
Domain Name System Sender Policy Framework record, or DNS SPF record for short, is a DNS record that provides important information about a domain name that indicates the outgoing mail servers it has.
If the MX records show which email servers should handle incoming emails for a domain name, the SPF records show which email servers should send emails on behalf of a domain name.
When you send an email to another person, like, for example, John@site.com, the incoming mail servers of site.com will first check your domain name. They will be searching for the SPF record and follow the rules that it establishes. Only if the SPF record is present, then your email will be received without been discarded or put into the SPAM box.
