Crafting Compelling Subject Lines: Dos & Don'ts
Updated over a week ago

Crafting the perfect cold email subject line can make or break your outreach success.

Over 90% of cold emails fail due to poor subject lines, so it's crucial to understand the key dos and don'ts of grabbing your prospects' attention.

While Luna.ai does the heavy lifting and already crafts compelling subject lines, knowing the following dos and don'ts will help you improve your results.

The Dos of Cold Email Subject Lines

  1. Keep it concise: Aim for 1-3 words that pack a punch and clearly convey the email's purpose, such as "onboarding" or "customer churn"

  2. Tease the subject: Pique your prospect's curiosity by hinting at the topic you'll discuss in the email, like "email outreach question"

  3. Use lowercase: Selectively using lowercase subject lines can help your email stand out in a sea of title-case subjects.

  4. Be boring: Avoid flashy or gimmicky subject lines; instead, opt for clear and straightforward language that reflects the email's content.

The Don'ts of Cold Email Subject Lines

  1. Don't ask questions: Avoid using questions in your subject lines, as they can appear

    presumptuous or pushy.

  2. Don't use first and last names: Including the prospect's full name in the subject line can make your email seem impersonal and automated.

  3. Don't mention the company name: Refrain from using the prospect's company name, as it can make your email appear less genuine and more like a mass-sent message.

  4. Don't try to sell: Your subject line shouldn't scream "sales email." Instead, focus on hooking your prospect's interest.

  5. Don't use overused subject lines: Steer clear of generic or commonly used subject lines that fail to capture attention or convey value.

Bonus Tips for Crafting Winning Cold Email Subject Lines

  1. Practice patience: Resist the urge to sell in your subject line. Build intrigue and encourage prospects to open your email to learn more.

  2. Employ internal camouflage: Make your subject line appear as though it came from within the prospect's organization, increasing the likelihood of them opening it.

  3. Avoid clickbait: Ensure your subject line accurately reflects the content of your email. Misleading subject lines erode trust and damage your credibility.
