Email Spam Words Checker

Paste your subject and email body to highlight words worth reviewing. Free to use; word flags do not predict inbox placement.

Review your subject and email copy

Read flagged words in context. Keep accurate details and remove misleading promises or urgency.

Check links and message formatting

Make the sender and purpose clear. Check link destinations and preview the message before sending.

Test your email placement

Send a placement test to see where that message lands in the test inboxes. Results can vary by recipient and provider.

Verify email authentication

Review SPF, DKIM and DMARC for your sending setup. Correct authentication matters, but does not guarantee inbox delivery.

Review public domain and IP signals

Check DNS and relevant public blocklists. A clean result does not reveal every provider’s private reputation signals.

Review recipients and sending results

Send messages people expect, honor unsubscribe requests, and investigate bounces and spam complaints.

Understand the next deliverability check

Review wording in context and learn which issues need more than a copy edit.

Frequently Asked Questions

What does this free email spam checker test?
It highlights matches from Folderly’s word list in the subject and email body you enter, including certain money and percentage symbols. The count is a wording-review aid, not a spam probability, AI assessment, or inbox placement score. It does not check your sending domain, authentication, recipient list, or mailbox provider’s filtering decision.
How do I check my email for spam words?
Replace the sample subject and body with your own copy. Highlights update as you type. Review each match in context, edit your wording where useful, and check again. The tool does not rewrite or remove words for you. Use Refresh to clear both fields.
Should I remove every flagged word?
No. A match is a prompt to review meaning, not proof that a provider will reject the message. For example, “Hurry up! Guaranteed income” deserves scrutiny because it makes a strong promise and adds pressure. A truthful “Your free trial ends tomorrow” may need to keep “free” to explain the offer. These are illustrative copy examples, not tested placement results. Prefer accurate, relevant wording over substitutions made only to lower the count.
Does zero flagged words mean my email will reach the inbox?
No. Zero means this list found no matches in the supplied copy. Authentication, sender reputation, recipients’ spam complaints, message formatting and receiving policies can still affect delivery. The checklist percentage below the editor records items you mark complete; it is not a measured inbox rate.
Why can Gmail or Outlook mark a well-written email as spam?
Providers consider more than wording. Google’s sender guidelines cover authentication, DNS, spam complaints, accurate messages and unsubscribe requirements. Microsoft’s anti-spam guidance also covers sender reputation, message content and organization-specific policies. Review the relevant provider’s requirements and any rejection or message-header evidence instead of assuming a flagged word caused the problem.
Which check should I run after reviewing the words?
Use Folderly Flash to send an actual test message and review its authentication and content checks. Use Folderly Lens for public DNS, domain and IP signals. For placement in test inboxes, use Inbox Insights. These checks answer different questions; none guarantees delivery to every recipient.
Can this checker write or improve my email?
This checker highlights wording; you make the edits. For a starting draft, use the Folderly AI email generator, then verify the facts, tailor it to the recipient and review it here. You can also request a template review through the form above. Neither a generated draft nor fewer word flags proves inbox placement.
