Writing a sales email that gets opened starts with one thing: the subject line. No matter how amazing your pitch is, it means nothing if your prospect never clicks open. In the sea of inbox clutter, your subject line is the hook that either reels them in or gets scrolled past.
In this guide, we’re breaking down over 80 proven sales email subject lines to inspire your next outreach campaign. From cold emails to retargeting, follow-ups to pain point angles — we’ve got you covered.
What Makes a Great Sales Email Subject Line?
Before diving into the subject line list, here are five principles that drive high open rates:
- Clarity Over Cleverness: Avoid vague or overly creative lines. Get to the point.
- Brevity Wins: Aim for 6-8 words. Anything longer might get cut off on mobile.
- Personalization Pays Off: Using the recipient’s name or company can increase open rates by 20% or more.
- Pain Point Focus: Highlight a problem your recipient is actively experiencing.
- Curiosity Triggers Clicks: Tease a benefit, insight, or question they feel compelled to answer.
