How to Write Winning Email Subject Lines

Updated over a week ago

Heeeeey lemlister! 👋

Subject lines are a critical factor in your email campaign’s success. They set the tone, entice prospects to open your email, and build trust by matching the email content. Let’s explore how to craft subject lines that make your emails stand out!


Key Elements of a Great Subject Line

A good subject line should:
👉 Set the tone: Reflect your message’s personality and purpose.
👉 Encourage opens: Spark curiosity or provide value.
👉 Match the content: Deliver what your email promises to avoid misleading your audience.

💡 Pro Tip: Test different approaches to find what works best for your audience.

Tips for Writing Subject Lines in Lemlist

  1. Step 1 Subject Line is Mandatory:
    For the first email in your sequence, you must include a subject line. For subsequent steps, if left blank, Lemlist will reuse the subject from Step 1 (without adding "RE:").

  2. Custom Variables in Subject Lines:
    Personalize your subject lines using custom variables. For example:

    • “{{firstName}}, quick question about {{companyName}}”

    • “An idea for {{industry}} leaders like you”

  3. Keep it Short and Catchy:
    Subject lines with fewer than 50 characters tend to perform better.


Examples of Effective Subject Lines

  • Curiosity-Based:

    • “{{firstName}}, you’ll want to see this!”

    • “An opportunity for {{companyName}}”

  • Value-Focused:

    • “Save hours on {{pain point}}”

    • “How to improve your {{specific goal}}”

  • Personalized:

    • “Loved your post on {{topic}}, {{firstName}}”

    • “Let’s talk about {{specific challenge}}”


Testing and Optimizing

  • Experiment with different tones: Formal, playful, or conversational.

  • A/B test subject lines to see which drives the highest open rates.

  • Analyze results and tweak your approach based on what resonates with your audience.


Final Thoughts

Your subject line is the first impression your email makes—use it wisely! Personalization, relevance, and creativity are your best allies for crafting impactful subject lines.
