One More (AI) Thing

Use AI to generate subjects, preview texts, and alt texts in multiple languages.

When used tastefully, AI can help you craft better emails and reach humans instead of spam filters.

Today, we're announcing three new AI-powered features to enhance your emails:

All our new features use your own brand voice and native language.

AI Subject Lines

You can now generate subject lines in the Templates and Broadcasts editors using AI.

The subject line generator is powered by Resend's deliverability expertise, making your emails more likely to land in the inbox.

AI Preview Text

An email's preview text encourages your recipients to open your email. It's important to follow these best practices:

  • Keep it concise (40 to 90 characters)
  • Use action-oriented language to prompt engagement
  • Ensure the preview text aligns with the brand's voice
  • Avoid using all caps, excessive punctuation, or urgent language

All of this is taken into account when using Resend's preview text generator.

AI Image Alt Text

Alt text (alternative text) describes the contents of an image and is helpful for:

  • Visually impaired users
  • As a fallback when an image fails to render
  • Improving deliverability, since it helps email clients understand the content of the email

Resend will automatically generate alt text for your images upon upload. After it's generated, you can edit the alt text using the properties sidebar or regenerate it if you prefer a different description.

Works for Every Language

All of these new features work for emails in all languages. We detect the language from the body of the email and generate text in the same language.

For example, if you're writing an email in Japanese, the editor will generate preview text, alt texts, and a subject line in Japanese.

Try It Out

These new AI features help you send inbox-ready emails by default.

You can use them in the Broadcasts editor and Templates editor today.
