The Problem
Your emails might not be reaching the inbox
Since February 2024, major email providers enforce strict authentication requirements. Domains that fail compliance are silently rejected.
Emails Rejected
Google, Microsoft, and Yahoo now reject emails from domains without proper SPF, DKIM, and DMARC. Non-compliant senders get a permanent 550 error.

Testimonials
Trusted by security-conscious teams
See how businesses protect their email deliverability and domain security.
“We were getting rejected by Gmail and didn't know why. DNS Sidekick identified three misconfigured records and we fixed them in minutes. Our deliverability went from 72% to 98%.”
“Managing DMARC for 30+ client domains was a nightmare with spreadsheets. Now we have one dashboard, real-time alerts, and white-label reports. Our clients love it.”
“The compliance dashboard alone is worth the price. We passed our SOC2 email security audit on the first attempt because DNS Sidekick kept everything monitored and documented.”
“I had no idea our SPF record had too many lookups until the free scan caught it. Simple fix, but it was silently dropping 15% of our emails for months.”
“As a non-technical CEO, I finally understand our domain security posture. The plain-English reports and health scores make it easy to know we're protected.”
“The real-time alerting caught a DNS change that would have broken our DKIM within minutes. Without DNS Sidekick, we wouldn't have known for days.”
