Frequently Asked Questions
- What is email preview text?
- Email preview text, also called preheader text, is the snippet that appears next to or below the subject line in many inboxes before the email is opened.
- How long should preview text be?
- A practical target is about 40-130 characters, with the strongest detail near the beginning because mobile inboxes often show less text.
- How does the generator work?
- Paste email body copy or campaign notes, then generate a concise preview. You can edit the result, clean whitespace, and preview how it appears in an inbox.
- Should preview text repeat the subject line?
- No. It usually works better as supporting copy: clarify the benefit, add a detail, mention timing, or answer the question raised by the subject.
- Is my campaign copy stored?
- No. The generator runs in your browser session only and does not store your email copy.
