Paste your subject line and email body to spot the spam words, all-caps, exclamation marks, and emoji that nudge messages toward the spam folder. It runs free in your browser, flags wording by category, and stores nothing.

Spam filters and wary readers both react to wording. Paste your subject line and body, and the tool scans both for the phrases filters have long tied to junk mail, the money and urgency hooks like '100% free', 'act now', and 'cash bonus', then layers on the formatting that amplifies them: shouting in ALL-CAPS, stacks of exclamation marks, and a pile of emoji in the subject.
Matches are highlighted right inside the fields as you type and grouped by category below, each with a plain-language fix, so you can see why a phrase was flagged and clean it up on the spot. When you want a head start, it can draft a calmer version of your copy for you with a single click.
Treat it as a fast wording pass, not a full deliverability verdict. Modern filters at Gmail, Outlook, and Yahoo weigh authentication, sender reputation, and how people engage with your mail far more heavily than any single word, so clean copy helps but it is one piece of the picture. Everything runs in your browser, and nothing you paste is uploaded or saved.
Trigger words are underlined directly in your subject and body as you type, so you can fix them in place without hunting through a list.
Every match is sorted by why it stands out, money, urgency, free and offers, overpromising, or pushy, and each group comes with a concrete suggestion.
Generate a cleaner draft from rule-based phrase swaps, or run an optional on-device AI rewrite in supported browsers, then copy it or drop it straight back into the fields.
The scan and both rewrite paths run entirely in your browser. Nothing you paste is uploaded or stored, so you can check unsent drafts safely.
A quick read of how spammy the wording looks: low, medium, or high. It rises with the number of trigger words and the intensity of formatting like caps, exclamation marks, and emoji. A high reading means the copy is worth rewriting before a large send; low means the wording is clean.
Every matched phrase, grouped by why it stands out: money and financial, urgency and pressure, free and offers, overpromising, and shady or pushy. Seeing the category makes it obvious which hooks to soften, and the count shows how often each one repeats.
Words written entirely in capitals read as shouting and are a classic spam signal, especially in subject lines. A high caps ratio across the message is flagged. A single acronym is fine; a subject in full caps is not.
One is fine. Several, and especially runs like '!!!', pile on urgency that filters and readers both distrust. The count covers the subject and body together.
A tasteful emoji rarely hurts, but several in the subject line is a known spam pattern. The check counts emoji across the message and separately in the subject, where they carry the most weight.
Shouting plus '!!!' is one of the oldest spam tells. Even with clean authentication, a subject like 'FREE GIFT INSIDE!!!' invites filtering. Use sentence case and at most one exclamation mark.
Phrases like 'act now', 'limited time', 'risk-free', and 'cash bonus' are individually survivable, but several together read as a hard sell. Keep the offer, lose the pressure language.
A row of emoji in the subject line is a strong spam pattern at several providers. Keep emoji out of the subject, or limit it to one that genuinely adds meaning.
Clean copy will not rescue mail that fails SPF, DKIM, or DMARC, sends from a poor-reputation domain, or goes to an unengaged list. If wording looks fine but you still land in spam, the cause is almost always authentication or reputation.
