5 Foundational Best Practices for Unforgettable Sales Email Subject Lines

1. Prioritize Simplicity and Brevity

Your sales email subject lines should be short and sweet—1-5 words is ideal. That way the first line of the email is visible without opening it. Emails with shorter subject lines perform better, according to Mailchimp.

Email Subject Line For Sales No-No: Don’t send an email without a subject line. It can be perceived as lazy.

“The shorter your subject line, the more characters of the first line of the email they see. Make sure it’s personalized and resonates with the persona. Show them you know them.”

2. Personalize Your Sales Email Subject Lines

Make sure your sales email subject line is relevant to the recipient. When constructing your subject lines, write them in lowercase to appear casual and include their first name, e.g. [Name], question about your book.

Your recipient should feel like your email fits naturally among the regular correspondence they usually get—the kinds of emails they actually read.

Email Subject Line For Sales No-No: Never include generic greetings. Their email hosting may flag your email as spam, or the recipient may think it’s irrelevant. Instead, eschew them entirely and opt for the recipient’s name. E.g., Instead of Hi there or Hello begin your subject line with [Prospect name] can’t wait to speak with you this week.

3. Watch Your Tone

Be mindful of the tone of your sales email subject lines. Ensure your follow-up doesn’t read as pushy or your initial cold outreach doesn’t sound too formal. Be careful of phrases like ‘gentle reminder.’ (Will the next reminder be less gentle?)

Email Subject Line For Sales No-No: Never use phrases like ‘urgent,’ ‘read now,’ or ‘immediately’ unless it actually is vital. Otherwise, you’ll lose the lead’s trust and potentially turn them off from reading your email—or worse, get flagged as spam.

4. Evoke an Emotional Reaction

On the other hand, eliciting a positive emotional reaction—laughter, curiosity, competitiveness—is a great way to entice prospects to read your emails. Try challenging your prospect or evoking a reaction like surprise or joy. It can be helpful to include personal pronouns like ‘you’ as in “I have incredible news for you.”

Email Subject Line For Sales No-No: Avoid eliciting negative emotional reactions like panic, confusion, or anger. Even if your prospect opens your email, they may be left with a poor impression of you.

5. Don’t Get Jaded

Every failed subject is just another opportunity to learn. If at first you don’t succeed, try, try, and try again. Iterate and improve your subject lines. Not every one of them will be winners but when you apply these best practices, you’re sure to find something that works.
