Squarespace offers an AI writing tool built into its Email Campaigns product that generates full draft email campaigns — including subject lines and body copy — based on a user's stated goal, target audience, and brand identity.

Squarespace AI is integrated directly into the Email Campaigns editor, allowing users to generate first-draft blast campaign emails by describing a goal and selecting an asset (such as a product or image). The Brand Identity tool carries brand tone and description into the generated copy. At Refresh 2025, Squarespace also announced AI-generated campaign templates accessible via Beacon AI, enabling users to launch marketing emails with campaign-specific AI content from the main dashboard. Squarespace's official help documentation confirms this feature is available on Version 7.1.
