Email Preview Text & Subject Line Optimizer
See your inbox appearance before you hit send
Most preview text gets wasted on 'View this email in your browser' — the single most valuable line of real estate in your campaign. This tool simulates how your subject line and preview text will realistically display across major inbox clients, then scores the pairing for filler text, repetition, length, and curiosity/benefit signals so you can fix weak spots before you send.
- →Simulates Gmail mobile, Apple Mail iPhone, and Outlook desktop previews at realistic truncation lengths
- →Flags generic filler preview text like 'View this email in your browser'
- →Detects when preview text just repeats the subject instead of adding new information
- →Scores subject and preview length against practical visibility ranges
- →Watermarked by Cikal Studio Labs · Works on any device, no install required
