Spam Score Checker for AWS SES: Free Online Tool
→ Open the free Spam Score CheckerNo signup. 5 free checks a day. Works with any AWS SES campaign.
AWS SES's built-in tools cover the basics, but the spam score checker workflow often benefits from a dedicated check before sending. Pre-send spam-trigger analysis catches issues before they impact your sender reputation. Free rule-based scoring combined with a Naive Bayes classifier identifies precisely which content triggers fire.
Why pre-process before uploading to AWS SES
SES has no spam-scoring layer. External pre-send rule analysis fills the gap.

AWS SES-specific deliverability quirks to know
Amazon SES is the lowest-cost transactional sender ($0.10 per 1,000 emails) but provides no built-in deliverability tooling. Pre-send rule analysis is essential.
