Bardiah is an AI email design tool that turns campaign descriptions and copy into responsive HTML marketing emails. Users can describe an email or provide existing copy, and the tool creates a design using the brand settings saved for the project. These settings can include a logo, color palette, typography, voice samples, and visual references. Users can refine drafts through chat, including making changes to layout, fonts, and spacing. The tool is intended for founders, marketers, small agencies, and freelancers creating announcements, product updates, welcome emails, promotions, and newsletters. Projects can be kept separate for different clients, with brand settings applied to new emails in each project. Finished emails can be exported as HTML for Mailchimp or Klaviyo, or saved as a file. Bardiah also offers an HTML email previewer for checking designs and sending a test email to an inbox. Generated HTML uses table based layouts with Outlook fallbacks and inline styles for email client compatibility. Templates are designed for mobile screens as narrow as 320 pixels and do not require scripts or external dependencies. The free plan includes one email and three refinements per month, with no payment card required.
