As we delve into the world of email subject line generators, it’s essential to acknowledge the role of human writers in crafting compelling subject lines. While AI has made significant strides in analyzing audience psychology and generating effective subject lines, there are instances where human writers outperform AI. In fact, studies have shown that human-crafted subject lines can be more effective in certain situations, such as when a personal touch or nuanced understanding of the audience is required. With the average email open rate hovering around 20-25%, companies are constantly looking for ways to improve this metric. As we explore the capabilities of human writers in this section, we’ll examine the techniques professional copywriters use to craft subject lines that resonate with their audience, and discuss when human writers might have an edge over AI-generated subject lines.

When Human Writers Outperform AI

While AI-generated email subject lines have shown impressive results, there are scenarios where human writers outperform AI. Human-written subject lines tend to excel in campaigns that require a high level of creativity, emotional appeal, or nuanced understanding of the target audience.

For instance, in niche or highly specialized industries, human writers can craft subject lines that resonate with the audience’s specific needs and interests. A case study by JOANN found that using human-written subject lines for their email campaigns targeting quilting enthusiasts resulted in a higher open rate compared to AI-generated subject lines.

  • Humor and wit: Human writers can infuse subject lines with humor, sarcasm, or wordplay, which can be challenging for AI to replicate. A study by Mailchimp found that subject lines with a touch of humor can increase open rates by up to 20%.
  • Emotional connections: Human writers can create subject lines that tap into the audience’s emotions, such as empathy, nostalgia, or excitement. For example, a charity organization might use a human-written subject line that evokes a sense of urgency and compassion to encourage donations.
  • Complex or abstract topics: Human writers can craft subject lines that simplify complex or abstract concepts, making them more accessible and engaging for the audience. A case study by Persado found that human-written subject lines for a financial services company resulted in a higher click-through rate compared to AI-generated subject lines.

Additionally, human-written subject lines tend to perform better in campaigns targeting smaller, highly targeted audience segments. For instance, a startup targeting a specific group of early adopters might find that human-written subject lines resonate better with this audience than AI-generated ones.

It’s essential to note that while human writers can outperform AI in certain scenarios, AI can still be a valuable tool in the email marketing toolkit. By combining the strengths of human creativity with the scalability and data analysis capabilities of AI, marketers can create highly effective email campaigns that drive results.

  1. Use human writers for campaigns that require a high level of creativity, emotional appeal, or nuanced understanding of the target audience.
  2. Utilize AI-generated subject lines for larger, more generalized audience segments or for campaigns where data analysis and scalability are crucial.
  3. Test and compare the performance of human-written and AI-generated subject lines to determine the most effective approach for your specific campaign.

By understanding the strengths and weaknesses of both human writers and AI, marketers can make informed decisions about when to use each approach to maximize the impact of their email campaigns.

Techniques Professional Copywriters Use in 2025

When it comes to crafting high-performing subject lines, top human copywriters employ a range of strategies, frameworks, and psychological triggers to capture the attention of their audience. One key approach is to use personalization, where the subject line is tailored to the individual recipient based on their interests, behaviors, or demographics. For example, a study by Mailchimp found that personalized subject lines can lead to a 10-15% increase in email open rates.

Another effective technique is to use scarcity or urgency in the subject line, creating a sense of limited-time offer or exclusive deal. This can be achieved through the use of words like “limited time,” “exclusive,” or “ending soon.” According to Persado, an AI platform that allows users to personalize communications at scale, using scarcity or urgency in subject lines can result in a 20-30% increase in open rates.

Human copywriters also use storytelling techniques to craft subject lines that tell a story or create an emotional connection with the recipient. This can be achieved through the use of vivid imagery, metaphors, or anecdotes. For instance, a subject line like “The Secret to Unlocking Your Full Potential” creates a sense of intrigue and curiosity, making the recipient more likely to open the email.

In addition to these techniques, top copywriters also use data-driven insights to inform their subject line creation. This involves analyzing past email performance, identifying patterns in language and audience behavior, and using this information to generate subject lines that are more likely to resonate with the target audience. As noted by IBM, “AI marketing platforms can create AI marketing strategies and analyze data faster than humans, allowing businesses to focus on strategic initiatives.”

Some of the key frameworks and psychological triggers used by human copywriters include:

  • The Curse of Knowledge: assuming the recipient has prior knowledge or context, and using this to create a sense of intrigue or mystery.
  • The Power of Reciprocity: using the subject line to offer something of value or provide a solution to a problem, creating a sense of obligation or reciprocity.
  • The Scarcity Principle: using the subject line to create a sense of limited-time offer or exclusive deal, making the recipient more likely to take action.

By employing these strategies, frameworks, and psychological triggers, human copywriters can craft subject lines that are more likely to capture the attention of their audience and drive engagement. As JOANN has seen a 10% increase in email open rates by using AI-generated subject lines, it’s clear that the use of AI in email marketing is on the rise, and human copywriters must adapt and evolve to stay ahead of the game.
