Email deliverability is the ability of your emails to reach recipients' inboxes successfully. It's affected by multiple factors including authentication records (SPF, DKIM, DMARC), sender reputation, content quality, and engagement rates.
Specifies which mail servers are authorized to send emails from your domain. Helps prevent email spoofing.
Adds a digital signature to emails, allowing recipients to verify the message came from your domain and wasn't altered.
Builds on SPF and DKIM to tell receiving servers what to do with emails that fail authentication checks.
