Subject lines are the make-or-break aspect of any email in a content marketing campaign. After all, it doesn’t matter how great the content of your email is if people aren’t opening it!

Discover three ways to use generative AI to improve, craft, and generate excellent subject lines and improve your open rates.

Key Takeaways

  • A/B testing with AI: Generative AI can create multiple subject line variations to help you identify the best ones for your audience. 
  • Use generative AI for subject line brainstorming: AI can help brainstorm new subject line ideas for specific email messages.
  • Generate subject lines with our Email Generator: Generative AI tools like our Email Generator are excellent for crafting high-quality email content.
  • Always fine-tune the output: As with any generative AI output, always tweak and edit it to ensure it is tailored to your audience.

Subject Lines and Why They’re So Important

The importance of a good subject line cannot be understated. Many email marketers spend hours crafting incredible body copy and then quickly draft a subject line to match. 

However, the very best in the business flip this process on its head. Instead, they spend more time on subject line creation, as without a great subject line, readers won’t open emails, in which case the body content won’t have a chance to be seen.

A great subject line can entice the reader to open a message, help them understand what content to expect inside, and motivate them to respond to a call to action.

A poor subject line will lead to fewer people opening emails, a lack of engagement, and the risk that emails may begin to appear in readers’ spam inboxes.

3 Ways to Use AI to Improve Subject Lines and Open Rates

Now, let’s review how AI can improve email subject lines to increase open rates.

A/B testing 

Firstly, generative AI can be an excellent tool for A/B testing, helping brainstorm different subject line variations to test.

By conducting A/B testing, you can check which subject line best resonates with a small part of your audience before sending the best subject line to the remaining audience.

Let’s say, for example, you run an e-commerce clothing brand, and you are about to offer a 48-hour 20% discount. You want to ensure as many people as possible interact with the sale, so you need to test a range of subject lines to see what is most successful.

Here’s an example prompt: “I run an ecommerce clothing brand, and we are about to run a 48-hour 20% off discount. We want to ensure as many people as possible interact with the sale, so we need to test a range of subject lines to see what is most successful. Please provide 3 examples of urgency subject lines, 3 examples of curiosity subject lines, 3 examples of friendly subject lines, and 3 examples of quirky subject lines”

Immediately, you have a variety of subject lines to pick from and further optimize, testing which tone of voice best resonates with your audience.

Brainstorming

AI tools can also be excellent for brainstorming new subject line ideas based on the message you are trying to convey to your audience.

Let’s use the e-commerce sale example once more.

Here’s an example prompt: “I run an ecommerce clothing brand, and we are about to run a 48-hour 20% off discount. We want to ensure as many people as possible interact with the sale. From the top studies and articles on this subject, what are some of the most important aspects that I need to include in my email subject lines?”

From there, you can continue to customize the email subject lines so they reflect the brand voice and tone.

Generating subject lines (and email content)

Lastly, generative AI can be an excellent tool for generating subject lines and even the email’s body copy. The Originality.ai Email Generator, for example, is a great tool for this, as it asks for plenty of detail before getting a response, such as purpose, recipients, and tone. This ensures the results are tailored specifically to your needs.

Here’s an example of how it works:

The prompt:

Email purpose: I run an ecommerce clothing brand, and we are about to run a 48-hour 20% off discount. We want to ensure as many people as possible interact with the sale.

Recipient information: 18-24-year-olds who have purchased from our brand before or are leads that have opted into marketing but never purchased

Tone: Informative

The results:

Just like that, we have a detailed email with a great, eye-catching subject line. We can then copy the information or fine-tune it even further using the button at the bottom right.

Final Thoughts on Generative AI for Email Subject Lines

Generative AI can be an incredibly effective tool for creating subject lines and even emails. However, it’s important to note that using generative AI for email content creation still has some of the same issues as AI article creation, so it’s important to take the time necessary to tweak and personalize the content.

Frequently Asked Questions

Why is it important to check for plagiarism?

Tools for conducting a plagiarism check between two documents online are important as it helps to ensure the originality and authenticity of written work. Plagiarism undermines the value of professional and educational institutions, as well as the integrity of the authors who write articles. By checking for plagiarism, you can ensure the work that you produce is original or properly attributed to the original author. This helps prevent the distribution of copied and misrepresented information.

What is Text Comparison?

Text comparison is the process of taking two or more pieces of text and comparing them to see if there are any similarities, differences and/or plagiarism. The objective of a text comparison is to see if one of the texts has been copied or paraphrased from another text. This text compare tool for plagiarism check between two documents has been built to help you streamline that process by finding the discrepancies with ease.

How do Text Comparison Tools Work?

Text comparison tools work by analyzing and comparing the contents of two or more text documents to find similarities and differences between them. This is typically done by breaking the texts down into smaller units such as sentences or phrases, and then calculating a similarity score based on the number of identical or nearly identical units. The comparison may be based on the exact wording of the text, or it may take into account synonyms and other variations in language. The results of the comparison are usually presented in the form of a report or visual representation, highlighting the similarities and differences between the texts.

String comparison is a fundamental operation in text comparison tools that involves comparing two sequences of characters to determine if they are identical or not. This comparison can be done at the character level or at a higher level, such as the word or sentence level.

The most basic form of string comparison is the equality test, where the two strings are compared character by character and a Boolean result indicating whether they are equal or not is returned. More sophisticated string comparison algorithms use heuristics and statistical models to determine the similarity between two strings, even if they are not exactly the same. These algorithms often use techniques such as edit distance, which measures the minimum number of operations (such as insertions, deletions, and substitutions) required to transform one string into another.

Another common technique for string comparison is n-gram analysis, where the strings are divided into overlapping sequences of characters (n-grams) and the frequency of each n-gram is compared between the two strings. This allows for a more nuanced comparison that takes into account partial similarities, rather than just exact matches.

String comparison is a crucial component of text comparison tools, as it forms the basis for determining the similarities and differences between texts. The results of the string comparison can then be used to generate a report or visual representation of the similarities and differences between the texts.

What is Syntax Highlighting?

Syntax highlighting is a feature of text editors and integrated development environments (IDEs) that helps to visually distinguish different elements of a code or markup language. It does this by coloring different elements of the code, such as keywords, variables, functions, and operators, based on a predefined set of rules.

The purpose of syntax highlighting is to make the code easier to read and understand, by drawing attention to the different elements and their structure. For example, keywords may be colored in a different hue to emphasize their importance, while comments or strings may be colored differently to distinguish them from the code itself. This helps to make the code more readable, reducing the cognitive load of the reader and making it easier to identify potential syntax errors.

How Can I Conduct a Plagiarism Check between Two Documents Online?
