Why this problem
A typical company sends email from its mailbox provider plus a handful of other tools: a newsletter platform, a help desk, a billing system, a CRM. Each one needs SPF and DKIM set up for your domain, and nobody owns the full list.
Gmail and Outlook.com now require SPF, DKIM and DMARC from anyone sending 5,000 or more messages a day, and Outlook.com rejects non-compliant mail outright. The data to fix this already exists in DMARC reports, but those reports arrive as raw XML that few people read.
XenonPeak reads them for you. It is built for IT leads, marketing operations and domain owners at companies that want their mail delivered and their domain protected from spoofing, without hiring an email specialist.
How we work
Read-only access
We never ask for mailbox, admin console or DNS write access. Every fix is a record you publish yourself.
Careful policy changes
We only suggest tightening DMARC after 14 days of clean data, because blocking your own invoices is worse than doing nothing.
Published prices
Plans, limits and overage rates are on the pricing page. You get warnings at 80% and 100% of your allowance.
Your data leaves with you
CSV export at any time, and full deletion within 30 days of cancellation or request.
