2. Choose the newsletter theme that best matches your current send, such as Company Updates, Product Launch, or Employee Recognition.
3. Set the count slider to the number of subject lines you want generated — eight is a good default for an A/B testing batch.
4. Click Generate and review the list, noting which formats feel most aligned with your brand voice and newsletter content.
5. Copy your two or three strongest options and paste them directly into your email platform's A/B test or subject line field.

Use Cases

• •A/B testing two subject lines in Mailchimp before a major product launch send to 10,000 customers
• •Writing a batch of eight subject lines for a monthly all-hands internal employee update
• •Generating investor-ready subject lines for a formal quarterly earnings and milestones newsletter
• •Building a two-month swipe file of B2B subscriber subject lines for a weekly industry insights roundup
• •Refreshing stale subject line templates for a community members newsletter covering nonprofit donor updates

Tips

• →Generate subject lines for the same theme twice with different audience settings to spot which framing translates across segments.
• →Pair a generated subject line with a strong preheader — together they act as a two-line pitch that appears before the email is opened.
• →If a generated line uses a number or list format ('5 things…'), test it against a question-format line — these two structures often trade performance by industry.
• →For internal newsletters, avoid subject lines that read like broadcast announcements; lines that imply relevance to the reader personally ('Your Q2 team update') outperform generic headers.
• →Save subject lines that perform above your average open rate in a running doc — patterns will emerge about word choice, length, and format that are specific to your audience.
• →Use the generator at the start of your content calendar planning, not at the send deadline — strong subject lines sometimes suggest angles worth building the newsletter content around.
