Why Email Authentication Matters

DMARC, DKIM, and SPF are the three pillars of email authentication. Without them properly configured, your marketing emails can land in spam, your domain can be spoofed by bad actors, and your sender reputation takes a hit. Google and Yahoo now require DMARC policies for bulk senders, making this a non-negotiable for any brand running email marketing at scale.
