AWS SES's built-in tools cover the basics, but the GIF compressor workflow often benefits from a dedicated, browser-only preprocessor before uploading. Animated GIFs are deliverability-fragile — large GIFs trigger spam filters and slow render times. Pre-compression with gifsicle's lossy presets cuts GIF weight 40-70% without visible quality loss.

Why pre-process before uploading to AWS SES

SES supports GIFs via external image references. SES has no built-in size warnings.

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.
