Questions about spam filtering
What does this spam checker actually look for?
It scans your copy against 712 trigger phrases grouped into urgency, overpromise, money, shady and unnatural language, then separately checks the structural signals filters weigh: link count, image-to-text ratio, ALL CAPS, exclamation marks, and subject-line length.
Why do my emails still go to spam with no trigger words?
Because wording is the smallest part of it. Placement is decided mostly by authentication (SPF, DKIM, DMARC), the sending domain's reputation and age, how fast you ramped volume, and whether recipients engage. A perfectly worded email from an unauthenticated new domain will still land in spam.
Do trigger words alone get an email filtered?
Rarely on their own. Modern filters weigh many signals together, so one instance of a flagged word in an otherwise normal message is usually harmless. Density is what hurts: several urgency and money phrases in a short email is a recognisable pattern.
What are the Gmail and Yahoo bulk sender rules?
Senders above roughly 5,000 messages a day to those providers must authenticate with SPF, DKIM and DMARC, offer one-click unsubscribe, and hold spam complaints under 0.3 percent. Below that threshold the same signals still shape placement, they are just not enforced as a hard gate.
How many links should a cold email contain?
One. Every extra link divides attention and adds filtering risk, and messages with several links look like marketing rather than a note from a person.
Should cold emails include images or tracking pixels?
Prefer neither. Images raise suspicion and make a one-to-one message read like a campaign, and open-tracking pixels are increasingly blocked or pre-loaded, so they distort your metrics while adding a signal you do not need.
Does this tool send or store my email?
No. The check runs entirely in your browser. Nothing is uploaded, logged or retained, and there is no signup.
Will passing this check guarantee inbox placement?
No, and be wary of any tool that claims it will. This grades the content signals you control. Placement also depends on authentication, domain reputation, list quality and recipient behaviour, which no content checker can see.
