2. The Personalized Power Play

Balancing Scarcity and Value

Make sure your offer is valuable and time-limited.

Examples of Time-Sensitive Subject Lines

Use it for special promotions or limited-time offers.

4. The Mutual Connection Name-Drop

How to Find and Verify Mutual Connections

Use LinkedIn or networking events to find common connections.

Crafting Authentic Subject Lines

Keep it genuine and not too salesy.

Connecting the Statistic to the Recipient’s Interests

Make sure the stat is relevant to your recipient.

Examples of Data-Driven Subject Lines

• “Only 30% of businesses have a solid email strategy.”

6. The Provocative Statement

Crafting Thought-Provoking Subject Lines

Challenge the status quo to get noticed.

Balancing Controversy with Professionalism

Be bold, but stay respectful.

Examples of Thought-Provoking Subject Lines

• “Is your marketing strategy stuck in the past?”

• “Why your lead gen strategy might be failing.”

When to Use This Tactic

Use it when you have a strong, relevant point to make.

Bonus Tip: Test Your Email for Spam

Before you hit send, it's crucial to make sure your email doesn't end up in the spam folder. Even the best subject lines won't work if your email never gets seen. Use a spam checker to test your email subject line and body for spam triggers. A great tool to use is Mailmeteor's Spam Checker.
