Email Newsletter Writing Tips — Word Count and Structure
Email newsletters remain one of the most effective marketing channels for building customer relationships. If your subject line or body copy is the wrong length, your emails go unread. This guide covers optimal word counts and structure techniques for higher open and click-through rates.
Optimal Word Counts
| Element | Recommended Length | Notes |
|---|---|---|
| Subject Line | 6–10 words (30–50 chars) | Mobile shows ~30 chars |
| Preheader | 8–15 words (40–90 chars) | Supplements the subject line |
| Sender Name | 2–4 words | Brand + person name is ideal |
| Body Copy | 100–400 words | Adjust by purpose |
| CTA Button | 2–5 words | Start with an action verb |
Place your most important keywords within the first 30 characters of the subject line. Use Character Counter to verify length before sending.
Body Copy Structure
- Sale/promotion: 50–150 words (concise, action-focused)
- Content digest: 150–250 words (summaries + links)
- Newsletter column: 250–400 words (substantive reading)
- Drip campaign: 150–300 words (one topic per email)
The first 2–3 lines must hook the reader. Place CTA buttons in both the middle and end of the email.
Boosting Open Rates
- Optimize send day and time — Tuesday through Thursday, 10 AM–12 PM
- Personalize the sender name
- Leverage the preheader with 40–90 characters of supplementary text
- Personalize content based on reader behavior
- Maintain 1–2 emails per week frequency
Surprising Facts
Email marketing reportedly delivers the highest ROI of any channel — an estimated $36–42 return per dollar spent. Including the recipient's first name in the subject line can boost open rates by an estimated 20–30%.
Common Mistakes
- Spam trigger words — Overusing "FREE," "ACT NOW," or excessive symbols increases spam folder risk.
- Body too long — Emails over 500 words cause mobile abandonment. Keep to one topic and link out for details.
- CTA only at bottom — Readers who abandon mid-email never see it. Place CTAs in multiple locations.
Conclusion
Keep subject lines to 6–10 words, body copy to 100–400 words, and place key messages in the first 30 characters. Use Character Counter to check your newsletter text.
