Why Is My Email Going to Spam?
Paste your raw email source and get an instant diagnosis. We analyze SPF, DKIM, DMARC alignment, blacklists, spam triggers, and give you AI-powered fixes — no signup required.
How it works
Open a spam-rejected email in your mail client, view the "raw source" or "show original", paste it below. We parse every header and check SPF/DKIM/DMARC alignment, blacklist status, spam trigger words, and suspicious links.
How to get your raw email source
Gmail
Open email → 3 dots menu → "Show original"
Outlook (Web)
Open email → 3 dots → "View" → "View message source"
Apple Mail
View → Message → Raw Source (or Cmd+Shift+U)
Thunderbird
View → Message Source (or Ctrl+U)
Common Reasons Emails Go to Spam
SPF Failure
Your sending IP is not listed in your domain's SPF record, so receiving servers reject or quarantine the email.
DKIM Missing or Broken
The DKIM signature is absent or fails validation, meaning the message may have been tampered with or is unverified.
DMARC Policy Rejection
SPF or DKIM don't align with the From: domain, triggering a DMARC reject or quarantine policy.
Blacklisted Sending IP
The IP your mail server uses is listed on one or more real-time blacklists (RBLs) due to past spam activity.
Spam Trigger Words
Content like "free", "guaranteed", "urgent", excessive capitalization, or certain phrases trigger Bayesian spam filters.
Missing List-Unsubscribe Header
Bulk email without a proper unsubscribe header gets penalized by Gmail, Yahoo, and other major providers.
Also check your domain's DNS configuration
Sometimes the root cause is a misconfigured DNS record, not the email content itself. Run a full DNS and email security scan for your domain to catch SPF, DKIM, and DMARC issues at the source.
