Why Compress to 70KB?
Newsletter builders like Mailchimp, Constant Contact, and Brevo (formerly Sendinblue) recommend keeping inline images under 100KB for fast rendering in email clients — 70KB is a sweet spot that loads quickly even on slow mobile connections while still looking crisp. Etsy and eBay listing thumbnails render at small dimensions where 70KB provides excellent quality without slowing down category-page scroll performance. Many WordPress themes default to thumbnail sizes (150x150 or 300x200) where 70KB captures all the necessary detail.
Tips for Compressing to 70KB
For email newsletters, compress to 70KB and also specify width in the HTML — most email clients do not resize gracefully.
Product images on white backgrounds compress more efficiently than complex lifestyle photos at the same file size.
Test how your 70KB image looks on both desktop and mobile email clients before sending a campaign.
