Can AI Write Better Email Subject Lines Than Humans?

AI has taken center stage in revolutionizing how we approach email marketing. Brands like JOANN have witnessed a remarkable 10% increase in email open rates, thanks to the influence of AI. If you’re not an expert email marketer, crafting compelling subject lines can be a daunting task, especially when sending personalized emails regularly. This often requires writing multiple subject lines and conducting split tests to identify the most effective ones, which can be a time-consuming endeavor. In this post, we will delve into how AI functions with email subject lines and why you should draw inspiration from AI when crafting your email subject lines. Additionally, we’ll explore some of the top AI email subject line generators.

How AI Works With Email Subject Lines

Many AI technologies are still in their early stages, but some have rapidly evolved to become game-changers. Two key technologies driving this AI explosion are Natural Language Processing (NLP) and Natural Language Generation (NLG). NLP allows machines to “read” text and convert it into a format that machines can understand, while NLG enables machines to generate their content based on this data.

AI-powered marketing tools like Acrolinx use NLP to assess your content and provide recommendations for improvement. NLP and NLG also play a crucial role in creating email subject lines. AI tools are trained on extensive email engagement data, which is derived from email best practices. This training empowers AI tools to generate unbiased subject lines that significantly boost open rates.

As Parry Malm aptly puts it, “When humans make choices, they inject their own experience, thoughts, and beliefs,” leading to potential biases in subject line selection. AI, on the other hand, is devoid of bias and relies on pattern matching, making its decisions free from cognitive biases.

Now, let’s explore some of the best AI tools for generating email subject lines.
