Why you need these DNS records
Your domain's DNS (Domain Name System) acts as the public address book for your email. Without the correct records, mailbox providers like Google and Yahoo will likely route your emails to the spam folder.
MX Records (Mail Exchange)
MX records tell the internet where to deliver emails sent to your domain. If you do not have MX records, you cannot receive any incoming email.
SPF (Sender Policy Framework)
SPF acts as a guest list for your domain. It is a TXT record that lists the exact IP addresses and services (like Mailchimp or Google Workspace) that are authorized to send email on your behalf.
DMARC (Domain-based Message Authentication)
DMARC ties SPF and DKIM together. It tells receiving servers exactly what to do (reject, quarantine, or do nothing) if an email fails authentication. Without DMARC, your domain is vulnerable to spoofing and phishing attacks.
