Free deliverability tool

Email Spam Analyzer

Paste your cold email subject and body. We'll flag the words, formatting and structural patterns that get cold email filtered.

Paste a subject and body to see the analysis.

What this tool actually checks

We score your email against the patterns that consumer and B2B spam filters consistently penalise: trigger phrases, ALL CAPS, punctuation noise, dense links, and subject-line shape. The score is a directional signal — no client-side tool can perfectly predict Gmail or Outlook, but addressing the flagged issues meaningfully reduces filter risk.

What it doesn't replace

  • Inbox placement testing across real seed mailboxes
  • SPF, DKIM and DMARC authentication on your sending domain
  • Mailbox warmup and consistent volume ramp

Run our SPF, DKIM and DMARC checkers next.
