FAQ
Why did my email suddenly start going to spam?
Gmail and Yahoo (Feb 2024) require every sender to pass SPF or DKIM, and bulk senders (around 5,000+ messages a day) to have SPF, DKIM and DMARC. Microsoft applies the same bulk rules to Outlook.com since May 2025. Mail that fails gets junked or rejected, and smaller senders lose trust too. A missing DKIM key or a second SPF record is enough.
What is a "DMARC fail"?
DMARC passes only when SPF or DKIM passes and matches the domain in your From address. The classic failure: your newsletter tool signs with its own domain, not yours. Your plan shows exactly which tool needs DKIM set up.
Do you need access to my DNS or email?
No. We only read public DNS. You paste the records yourself in your DNS host (GoDaddy, Namecheap, Cloudflare, Squarespace, etc.).
Can this get me off a blocklist?
We tell you which lists you're on and link the removal pages, but listings usually follow a cause (a compromised account, a bought list). Fix the cause first or you'll be relisted.
Is this a deliverability guarantee?
No. Authentication is the foundation every inbox checks first, but content, list quality and complaint rate still matter. If the plan doesn't help, you get a refund.
