Subject Lines
- Curiosity gap—promise value, don't reveal everything
- Specific > vague: "5 tools I use daily" > "Useful tools"
- Numbers work—quantified promises feel tangible
- Personal: "you" and lowercase feels like friend
- Urgency when genuine—time-sensitive content only
- Test constantly—small changes, big impact on opens
- Avoid spam triggers—"FREE", all caps, excessive punctuation
Preview Text
- Extension of subject, not repetition
- Complete the curiosity—add context that increases open
- Don't waste on "View in browser"—prime real estate
- First line of email becomes preview if not set—control it

- One main idea per issue—focus beats variety
- Scannable: headers, bullets, bold key phrases
- Consistent format—readers know what to expect
- Personal voice—distinct from generic corporate
- End with clear CTA—one action, not five
Frequency
- Consistency over frequency—weekly better than sporadic daily
- Set expectations at signup—"Every Tuesday" not "sometimes"
- Quality per issue matters more—don't pad to hit schedule
- Test frequency changes—some audiences want more, some less
