What does Skysnag do?
Skysnag is an email authentication and brand protection platform. It takes your domain to DMARC enforcement at p=reject, authenticates every message in real time and puts your verified logo and checkmark in the inbox. The core products are Protect, Certify, BrandGuard and Comply.
How long does DMARC enforcement take with Skysnag?
Skysnag Protect takes a domain to p=reject within 30 days. The guarantee covers the domains, access and delivery terms agreed with our team at onboarding. The industry average is 6 to 12 months.
Does enforcement put legitimate email at risk?
Protect identifies every service that sends as your domain and authorizes each one before the policy moves to p=reject, so legitimate email keeps reaching the inbox.
What is needed to show our logo and checkmark in the inbox?
BIMI requires DMARC at enforcement, a registered trademark, your logo as an SVG file and a Verified Mark Certificate. Skysnag Certify handles this as one engagement: about 30 days with a registered trademark, 4 to 6 months when registration is needed.
Which mailbox providers require email authentication?
Gmail and Yahoo have required SPF, DKIM and DMARC since February 2024, and Outlook since May 2025, for senders of more than 5,000 messages a day.
How does Skysnag protect customer data?
Customer data is encrypted with AES-256 at rest and in transit, with TLS on every connection, and hosted in AWS data centers compliant with SOC 2, ISO 27001 and HITRUST. Skysnag is available as SaaS or on-premises.
