Frequently asked questions

What counts as a spam trigger?
Words and patterns spam filters commonly weight heavily — phrases like "free money", excessive exclamation points, all-caps subject lines, and link-to-text ratio, checked locally against known heuristics.
Does a good score guarantee inbox placement?
No. It reduces content-based red flags, but deliverability also depends on your sending domain reputation and authentication (SPF/DKIM/DMARC) — this tool checks the message, not your domain setup.
Can I check multiple drafts?
Yes, paste a new draft any time; each check runs independently with no history saved.
