1Enable DKIM in your email provider and add the public key to your DNS zone
DKIM adds a cryptographic signature to your emails, proving they haven't been tampered with in transit and genuinely originated from your domain. Without it, attackers can forge emails that pass basic checks, and your legitimate emails are more likely to land in spam.
