Preview text best practices

  • • Keep preview text between 40-130 characters for best cross-client support
  • • Don't repeat the subject line — use it to add context or create curiosity
  • • Front-load the most important information
  • • Use action words and specific details (numbers, names, deadlines)
  • • Avoid special characters that may render differently across clients
  • • Don't start with 'View this email in your browser' — that wastes preview space

About this tool

Preview text (also called preheader text) is the snippet shown after the subject line in the inbox. It's your second chance to convince someone to open your email. This tool shows you exactly how your preview text will appear across Gmail, Outlook, Apple Mail, and other clients — each with different character limits. It also generates the HTML hidden div technique with invisible padding to prevent email clients from pulling in unwanted body content. Pair this with our subject line tester and preheader generator for maximum open rates.
