How to Use an AI Marketing Email Generator

Email has been part of the internet from the very beginning and quickly became a tool for marketing as well as personal and professional correspondence. Even with the rise of social media, it remains one of the most effective ways for marketers to reach their audiences.

Marketing email generators, such as QuillBot’s free marketing email generator, can help you write persuasive marketing emails that encourage clicks while staying true to your brand.

How to write a marketing email

Effective marketing emails strike a balance between clarity, persuasion, and brand consistency. Here are some best practices to help you get it right.

1. Keep it brief and focused

If the benefit of your marketing email isn’t obvious at first glance, it’s headed for the trash, so keep your messages short and direct.

Make sure you’re clear about the purpose of the email before you start writing. Are you promoting a product or special offer, sharing company news, or directing readers to online content?

If you find yourself trying to cover too much at once, split it up into separate emails or link to non-essential information instead of attempting to cram it all in.

2. Stay on-brand

You want people to open your marketing emails, but not because they’re looking for the unsubscribe button.

Remember that you’re communicating with valuable customers and prospects, so while your emails should be persuasive and include calls to action, they should also stay true to your brand identity and avoid coming across as spammy or untrustworthy. If you’ve developed voice and tone guidelines, use them to ensure that your emails are consistent with the rest of your communications.

3. Craft a compelling subject line

Your subject line is often the deciding factor in whether your marketing email gets opened or ignored. Make it clear why the reader should click—are they getting access to important news, a limited-time offer, or something they don’t want to miss?

Strong subject lines focus on benefits rather than features (e.g., “Fresh, seasonal veggies delivered to your door” rather than “Tasty seasonal vegetables”). Using action-oriented language in the imperative can also help grab attention and encourage readers to take the next step (e.g., “Get your farm-fresh box this week” rather than “Weekly vegetable box”).

4. Don’t forget the preheader

The preheader is the short line of text that appears alongside your subject line in the inbox.

Use the preheader to build on your subject line instead of just repeating it. If your subject highlights a benefit, the preheader could provide a specific offer (e.g., “Use code FRESH20 for 20% off your first two boxes”). Or if it poses a question, the preheader could hint at the answer (e.g., “Guess what’s new in your box this week?” → “Hint: it’s crisp, green, and only here for a short season”).

5. Personalize

Most email marketing platforms give you easy ways to personalize your messages, and it’s worth using them. Addressing readers by name in the email (and even in the subject line or preheader) makes your message feel more relevant and typically increases click-through rates.

Using an AI marketing email generator

An AI marketing email generator can help you quickly draft an effective marketing email. In your initial prompt, explain the purpose of your email, specify the voice and tone you’d like, and invite the AI to ask for any additional details it needs.

Carefully review the AI’s output to ensure it’s factually accurate and aligned with your brand, and use the chat to suggest improvements and refine the email until you’re satisfied with the final result.
