Crafting Subject Lines That Convert: Power Tips from Email Pros

Estimated read: 7 min Category: Copy & Creative

Your subject line is the gateway to performance. Make it clear, credible, and compelling-and watch open rates translate into clicks and revenue.

Clarity Over Cleverness

Be direct about value: "Exclusive 20% off today" will beat vague wordplay more often than not.

Use Actionable Language

Lead with verbs that spark motion-Download, Reserve, Explore-to prime readers to act.

FOMO & Urgency (Used Honestly)

"Ends tonight" or "Almost sold out" can lift response-just avoid false urgency that erodes trust.

Personalization, Sparingly

Simple touches like adding a first name or referencing a recent category can nudge opens without feeling invasive.

A/B Test Like a Habit

  • Short vs. long (35-55 characters often hits the sweet spot).
  • Question vs. statement.
  • Emoji vs. no emoji.

Avoid Spam Triggers

Skip ALL-CAPS, excessive punctuation, and sensational claims. Keep tone natural and credible.

Try "minicase" Styles

Occasional lowercase-first subject lines (e.g., "discover your new favorites") can feel more personal and scroll-stopping.
