Improve inbox access
DMARC helps ensure that every legitimate email from your domain reaches the intended inbox, providing peace of mind that campaigns will perform optimally.

Protect brand reputation
A phishing or spoofing attack can hugely damage brand trust and reputation, which is challenging – or even impossible – to repair. DMARC ensures that every email bearing your brand name is the real thing.

Increase ROI
DMARC supercharges your email deliverability, which means more eyes on your messaging, more often. This means you can maximize ROI and avoid getting lost in Spam or Junk folders.

Elevate brand recognition
Once DMARC is in place, you can implement Brand Indicators for Message Identification (BIMI), which boosts brand visibility and recognition by allowing for the display of your logo beside emails in inboxes.
