Deliverability Copilot
Paste a bounce message, an Authentication-Results header, or just describe what's going wrong — "my emails land in spam", "SPF permerror", "Gmail is rejecting me" — and get a plain-English diagnosis with fix steps. Free.
Heads up: the Copilot is AI and can make mistakes — double-check anything important before changing your DNS. Its guidance is based on OutboundAuth's guides, not a replacement for testing with your sending provider. For hands-on diagnosis, there's the $49 deliverability audit. Nothing you paste is stored; chats aren't logged.
