MiN8T Spam Score Checker interface preview

AWS SES's built-in tools cover the basics, but the spam score checker workflow often benefits from a dedicated, browser-only preprocessor before uploading. 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.
