Email attachments have strict size limits (Gmail: 25MB, Outlook: 20MB). Large photos from your phone (5-15MB each) quickly exceed these. Compress before attaching for reliable delivery.
Sending vacation photos, product images, or marketing materials via email often fails because images are too large. Compressing to 100-300KB per image solves this.
