FAQ

Common questions

Do spam words alone send me to spam?
Not on their own, but trigger words combined with poor authentication, cold domains and link-heavy copy add up. This tool removes one controllable risk factor.
What kinds of things get flagged?
Classic money/urgency words (free, guarantee, act now), ALL-CAPS, excessive exclamation marks, and too many links relative to text.
Is my email content stored?
No. The scan runs entirely in your browser: your copy is never sent to a server.
What matters more than spam words?
Deliverability fundamentals: authenticated, warmed-up mailboxes and a healthy sending reputation. Great copy can't save mail sent from a cold, misconfigured domain.
Copy is only half the battle

Make sure great copy gets seen

Even perfect copy lands in spam from a cold mailbox. MailOptimal sends from pre-warmed, fully authenticated mailboxes and personalizes with AI, so your words actually reach the inbox.
