Your email is broken.
You just don't know it yet.
Gmail, Outlook, and Yahoo silently send your business emails to spam when your DNS authentication is misconfigured. Most companies have no idea until customers stop replying.

Why are your business emails going to spam?
Since February 2024, Gmail and Yahoo require SPF, DKIM, and DMARC for bulk senders. Even small businesses sending invoices, proposals, or onboarding emails get caught. A single misconfigured record can silently route every email you send to spam — with zero error messages.
Blacklist monitoring catches the other half: if your mail server IP lands on Spamhaus, SpamCop, or Barracuda, your emails are blocked at the door. Most businesses don't find out until a customer asks “did you get my email?”
