AWS SES's built-in tools cover the basics, but the image compressor workflow often benefits from a dedicated, browser-only preprocessor before uploading. Reducing image weight before uploading keeps your email render-time fast and prevents Gmail clipping at 102 KB of HTML.

Why pre-process before uploading to AWS SES

SES does not host images. Pre-compressed assets at your CDN are critical at SES's typical high-volume sends.

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.
