Overview
AI Email Generation helps you create fully structured, brand-consistent email drafts using your prompt, attachments, Brand Voice, and brand theme.
This article answers the most common questions about how the feature works.
Getting Started
How long does email generation take?
Most emails generate within a few minutes.
Generation time depends on the amount of information the AI needs to process.
Short prompts usually finish faster.
Larger themes take longer.
Long documents increase processing time.
Multiple attachments require additional processing.
More context typically produces more accurate results.
Can you use AI Email Generation without Brand Voice?
Yes. You can generate emails without Brand Voice. Include tone and style directly in your prompt for better results.
For consistent messaging, set up Brand Voice before generating content.

Brand Voice
How does Brand Voice affect AI output?
