Next step
Fix the message before the campaign gets expensive.
The checker shows visible risks. Folderly Email Generator helps rewrite the message with a clearer reason to reply, calmer wording, and a safer next step.
Does this guarantee inbox placement?
No. The checker organizes visible copy, compliance, sender, and volume risks. Real inbox placement also depends on sender history, authentication, list quality, and mailbox-provider filtering.
Do you store the email I paste?
No. The public checker processes the submitted draft for the request and does not save raw email content.
What makes this different from a spam score?
Folderly reviews the message as a send-readiness system: copy risk, AI-template markers, opt-out handling, sender setup, complaint budget, and anonymized aggregate benchmarks.
