Spam-score checker FAQ
What is an email spam score?
A spam score estimates how likely a message is to be filtered as spam based on its content — trigger words, formatting, links, and tone. This tool analyzes your subject and body and flags the patterns that hurt placement.
Does a good spam score guarantee the inbox?
No. Content is only part of deliverability — authentication (SPF, DKIM, DMARC), sender reputation, and warmup matter just as much. Use this alongside the deliverability checker for a full picture.
How do I lower my spam score?
Remove trigger phrases and ALL-CAPS, cut exclamation marks and extra links, keep the subject 30–50 characters, and write in plain, specific, personalized language instead of promotional copy.
Is my email content sent anywhere?
No. This checker runs entirely in your browser — nothing you paste is uploaded or stored.
