Uploading custom HTML

While Sendigram offers drag-and-drop and pre-designed templates, advanced users may prefer to upload custom HTML to have complete control over the email design. This option is ideal if your design team has built templates externally or if you want to reuse existing HTML newsletters.

1. When to Use Custom HTML

  • You already have a pre-coded email design.
  • You want pixel-perfect control beyond what the visual editor allows.
  • You're migrating templates from another email service.
  • You're working with developers or agencies that provide ready-made HTML files.

2. Uploading Custom HTML for a Campaign

  1. Create a new campaign or edit an existing one.
  2. In the Email Template block of the Campaign Card, select Custom HTML.
  3. Choose how to import your code:
    • Paste HTML directly into the code editor.
    • Upload an HTML file from your computer.
  4. Review the preview pane to confirm formatting and layout.
  5. Save your template.

3. Editing Uploaded HTML

  • Use the built-in HTML editor to make small adjustments.
  • You can edit text, links, and minor styles directly in the code.
  • For major design changes, it's recommended to edit the file in your own development environment, then re-upload.

4. Adding Personalization to HTML

  • Insert personalization tags (e.g., {{First Name}}) directly into your code.
  • Ensure they match Sendigram's merge field syntax.
  • Test your code with sample contacts before sending.

5. Testing Your Custom HTML

  • Always send a test email to multiple email clients (Gmail, Outlook, Apple Mail).
  • Check mobile and desktop versions.
  • Validate that all links, images, and personalization tags work correctly.
