Your domain reputation starts the day you register it. Spammers actively target new domains that lack email authentication. Email Armory gives you free tools to set up SPF, DKIM, and DMARC from day one — so your transactional emails land in inboxes, not spam folders.
A startup sending password resets, onboarding emails, or invoices from an unauthenticated domain risks having those emails flagged as spam or rejected entirely. Worse, without DMARC, anyone can send emails that appear to come from your domain — damaging your brand before it's even established.
Setting up email authentication takes minutes with the right tools. Our record generators create copy-paste DNS entries, and our checkers verify everything is working. No email security expertise needed, no budget required.
