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 email 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, when it comes to enticing your prospects to read your emails, you should aim to elicit a positive emotional reaction, such as laughter or curiosity.
One effective way of doing so is by challenging your prospects, encouraging some healthy competition, or evoking a reaction like surprise or joy. It’s important to remember that people want to feel a connection, so using personal pronouns like ‘you’ can resonate with your message, as in “I have incredible news for you.” By taking the time to truly connect with your prospects in this way, you can build strong relationships and improve the success of your open rates.
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
Each failed subject line represents another opportunity to learn and grow. Don’t let a setback discourage you! Instead, approach it with the mentality that an iterative process is necessary for success.
In the case of your sales email subject lines, for example, you should keep trying different variations until you find the one that resonates with your audience. Adhering to best practices like personalization and brevity can also help increase the chances of success. So, don’t worry if every subject line isn’t a winner. You’ll find your stride in no time with persistence and these best practices.

For Cold Outreach—Use Curious Word Choices
Anyone who sends cold emails knows it sometimes feels impossible to break through the cluttered inboxes of prospects. With so many emails competing for attention, standing out and getting noticed can be difficult. Most people are hesitant to open emails from unknown senders, and even those who do may quickly delete them if they don’t seem interesting or valuable.
For cold outreach, you can’t rely on being a trusted name or business, so it takes extra work to engage prospects. The human brain prioritizes the novel—novelty triggers the release of dopamine in the brain as a reward, encouraging us to find out more. By using unusual words prospects are not expecting in a sales email, you may be able to grab a precious moment of their time.
Consider giving these curious sales email subject lines a try.
Picture your sales email as a mysterious suitcase. Imagine that your prospect has never seen or heard of it before. You’re responsible for offering your prospect this suitcase and encouraging them to open it—and your email subject line is the way to do it. If you present the suitcase with amazing, intriguing content inside, they will likely want to open it up and take a look.
The key here is to withhold just enough information to elicit curiosity in your prospect, making them want to know more. This generates a sense of excitement and anticipation in your prospect; they become driven to uncover the intrigue inside the suitcase. It becomes a mystery they are compelled to solve, leading them to click on your email and potentially engage with your brand. So next time you write that email subject line, remember the power of withholding information and offering it up like a mysterious, tempting suitcase.

When it comes to using internal camouflage in sales email subject lines, less is often more. If executed proficiently, utilizing internal camouflage can be a very effective way to catch a prospect’s attention and entice them to open your email. However, if not executed properly, your attempt to appear to be working for the prospect’s company may leave them feeling misled and frustrated.
It’s important to note that even when done effectively, trust is still a crucial component of any effective sales strategy. Instead of relying solely on internal camouflage, make sure to focus on building a genuine connection with your prospect by providing value and addressing their specific needs or pain points. Establishing that level of trust and building a relationship will increase the likelihood of success in the long run.
