AI for HTML Templates

In addition to per-email AI generation, Blesta 6.0 includes AI assistance for the HTML templates that wrap your email bodies. HTML templates control the outer markup, branding, and styling that every email uses, so AI here is helpful for producing on-brand, well-structured outer shells without writing email-safe HTML by hand.

Where to find it​

HTML templates live under Settings > Company > Emails > HTML Templates. From the add or edit screen for an HTML template, an AI Content Assistant button opens a generation/rewrite modal — the same UI used for per-email AI generation, scoped to the HTML template instead.

Prerequisites​

Same as per-email AI generation:

  1. A valid API key configured under Settings > System > AI.
  2. Email Templates feature checkbox enabled in Settings > System > AI > Enabled Features (the same checkbox covers both per-email and HTML template AI).
  3. Privacy notice acknowledged.

How it differs from per-email generation​

HTML templates are structurally different from email body templates:

  • They use email-safe HTML — heavy use of inline styles, table-based layouts, and <head> with non-standard restrictions.
  • They include placeholders for the inner email body (the actual per-email content rendered into the wrapper).
  • They include placeholders for branding (logo URL, company name, contact info).

The AI assistant is prompted to produce output suitable for email rendering: inline styles, tables for layout, fallbacks for clients that strip CSS, and predictable placeholders for the inner content.

Typical use cases​

  • Initial HTML template. Start from a generated baseline rather than pasting a template from elsewhere on the web. Provide an instruction like "clean, single-column, dark logo header, light body, brand color #2f739d".
  • Variant for a campaign. Generate a holiday or seasonal variant by rewriting an existing template with an instruction like "adjust palette for winter, keep layout identical".
  • Modernize an old template. Rewrite an existing HTML template for better mobile rendering or accessibility (e.g. "add a viewport meta, ensure all text has 4.5:1 contrast, replace center-tag with margin auto").

Working with the result​

The modal behavior is identical to per-email AI generation:

  • Generated output appears in the modal with an HTML preview.
  • Accepting populates the editor; you still click Save to persist.
  • Iterate by adjusting your instruction and regenerating.

Caveats specific to HTML templates​

  • Test before saving. AI may produce HTML that renders fine in your browser preview but breaks in older email clients (Outlook in particular). Send a test email and view in a few clients before committing to a generated template for production sends.
  • Branding consistency. The AI doesn't know your brand colors, logo URL, or tagline. Either include them in your instruction every time, or accept a generated baseline and edit branding by hand once before saving.
  • Compatibility with email body templates. If you change the inner-body placeholder name in a generated HTML template, your existing email body templates may not render correctly. Keep placeholder names aligned with what Blesta expects (the system documents the expected placeholders inline in the editor).
  • Email Templates — AI generation for the per-email body content rendered inside an HTML template.
  • Configuration — global AI settings including the model parameters that affect output quality.
