A few small things to check.
Two things, and they are not equal. Reputation - who is sending, from what domain, with what history - carries most of the weight. Content - what this particular email says and how it is built - carries the rest. This tool checks the content half thoroughly and reminds you about the reputation half, because a perfect draft on a broken domain still lands in spam.
Modern spam filters stopped pattern-matching single words years ago. What they weigh now are clusters: promotional language stacked together (free, guaranteed, act now, limited time), formatting that mimics scam mail (all caps, repeated exclamation points, colored text on loud backgrounds), and link patterns that look like phishing (many domains, URL shorteners, mismatched display text). One trigger word in an otherwise human email is fine. Six of them with three links is a pattern.
Before content is even read, mailbox providers ask: is this domain authenticated? SPF and DKIM prove the server may send for you; DMARC tells providers what to do when they fail. Then: do people engage with this sender? Opens, replies and rescues-from-spam build reputation; ignores and deletes erode it. A new domain sending volume too fast starts with suspicion. This is why a small, engaged list outperforms a big, cold one - the math of engagement rate is on the small list's side.
A content check like this one covers the draft. A true inbox placement test sends your email to seed addresses at Gmail, Outlook, Yahoo and others, then reports where each copy landed. Use one when you are launching from a new domain, changing platforms, or seeing engagement drop without a content explanation. For everything before that moment - the weekly send, the new sequence - a pre-send check and a healthy list are most of the battle.
Paste your subject line and email body. The tool scans for the content signals spam filters weigh: promotional trigger words, excessive links, URL shorteners, all-caps runs, heavy punctuation and formatting red flags. Everything runs in your browser.
No. Real placement depends mostly on sender reputation: your domain authentication (SPF, DKIM, DMARC), list quality and engagement history. A content check catches the part you control in the draft itself. For a true placement test, services send your email to seed inboxes across providers and report where it landed.
Filters care less about single words than they used to, but clusters of promotional language still count: free, guaranteed, act now, limited time, winner, cash, no obligation, risk-free, combined with all caps and stacked exclamation points. Context and reputation decide the outcome.
Yes. It is free, needs no account, and your email text is analyzed entirely in your browser - it is never uploaded or stored.
