Email signature logos: 200px that do not break
Use a 200 pixel email signature logo with retina doubling that loads fast and never breaks layouts.
Small images, big deliverability
Email logos should display at 200 pixels wide but load at 400 pixels for retina clarity. Files under 50 kilobytes open in under 2 seconds on 4G, while 500 kilobyte images trigger clipping in Gmail threads.
Host images with absolute paths and fixed width to survive Outlook 2019 and 2024 updates. When you generate your logo online, export PNG at 400 pixels wide with 72 dpi for perfect inbox scaling.
Layouts that stay intact
Stack logo, name in 14 point bold and contact in 12 point gray within 600 pixels total. Leave 20 pixels padding around marks so taps on 6 inch phones hit links without 15 percent mis-taps.
Test signatures in Gmail, Apple Mail and Outlook across 3 screen sizes before rollout to 100 staff. Update images every 2 years and keep backups at 200 and 400 pixels to fix broken links in 10 minutes.
