What Is an Email Preheader?
The preheader (also called preview text) is the snippet of text that appears next to or below the subject line in email clients. It's your second chance to convince someone to open your email - and most marketers either ignore it or let it default to "View this email in your browser."
The Email Preheader Generator creates compelling preview text that complements your subject line and boosts open rates by 5-15%.
How It Works
Enter your email subject line, the key benefit of your email, and your brand name. The tool generates 10 preheader variations using different approaches: curiosity, social proof, urgency, humor, and direct benefit statements.
Pick the one that best complements (not repeats) your subject line, and add it as preview text in your email editor.
Preheader Best Practices
• Keep it under 100 characters (40-90 is ideal) • Complement, don't repeat, your subject line • Use the preheader to answer the "why should I open this?" question • Include a call-to-action when appropriate • Test different preheader styles alongside your subject line A/B tests • Never leave the default preheader - it's wasted real estate

Frequently asked questions
How long should a preheader be?
Aim for 40-90 characters. Mobile shows less (30-55 chars), desktop shows more (up to 140). Front-load the most important words.
Should the preheader match the subject line tone?
It should complement, not copy, the subject line. If your subject creates curiosity, the preheader can hint at the answer. If your subject is bold, the preheader can add context.
