Creating email templates from structured data ensures consistency and makes automation easy. This tool generates responsive, email-client-compatible HTML that works in Gmail, Outlook, and other email clients. ## Tips for Better Email Templates - Keep your subject line under 50 characters and use the preheader field to add context that encourages recipients to open the email. - Use a single call-to-action button per email to focus the reader's attention and improve click-through rates. - Set a headerColor that matches your brand palette for instant visual recognition in the inbox. - Always include an unsubscribe URL and company address to comply with CAN-SPAM and GDPR email regulations. - Test your generated HTML in multiple email clients by sending test emails to Gmail, Outlook, and Apple Mail before launching a campaign. ## Frequently Asked Questions ### What fields can I include in the JSON? Include: subject, preheader, logo URL, headerColor, title, greeting, body (array of paragraphs), button (text, url, color), footer, companyName, companyAddress, and unsubscribe URL. All fields are optional except title and body. ### Is the output compatible with all email clients? Yes! The generated HTML uses table-based layout and inline styles for maximum compatibility with email clients including Gmail, Outlook, Apple Mail, Yahoo Mail, and Thunderbird. This approach follows email development best practices. ### How do I add a call-to-action button? Add a 'button' object with 'text', 'url', and optional 'color' properties to your JSON. The button will be centered and styled with your chosen color, using bulletproof button techniques that render correctly even in Outlook. ### Can I customize colors and branding? Yes! Set 'headerColor' for the email header background and 'color' in the button object. Use hex color codes like '#4f46e5'. You can also add a logo URL and company name for consistent branding across all your emails. ### What is the preheader text used for? Preheader is the preview text shown in email clients next to or below the subject line before opening the email. It is hidden in the email body but appears in inbox previews, making it a valuable space for encouraging opens. ### Can I use this for automated email pipelines? Absolutely. Since templates are generated from JSON, you can integrate this into any automation workflow. Define your email data as JSON in your backend, generate the HTML template, and send it via your preferred email service provider like SendGrid, Mailchimp, or Amazon SES. ### Does this tool support dark mode for emails? The generated templates use inline styles and standard HTML email patterns that render well in both light and dark mode. Email clients that support dark mode will automatically adjust background and text colors based on the inline style structure. ### Is there a file size limit for the JSON input? There is no strict file size limit. The tool processes everything in your browser, so performance depends on your device. For typical email templates with text, buttons, and footer content, the JSON input is usually well under 10 KB. ### How do I include multiple sections or paragraphs? The body field accepts an array of strings, where each string becomes a separate paragraph in the email. This lets you structure your email content with clear spacing between sections without writing any HTML yourself. ### Is my email data sent to any server? No. All processing happens entirely in your browser. Your JSON data and the generated HTML never leave your device, making this tool safe for emails containing sensitive business information or customer data. ## Related Tools - [JSON to Social Card](https://findutils.com/generate/json-to-social-card/) - [JSON to Invoice](https://findutils.com/generate/json-to-invoice/) - [JSON Formatter](https://findutils.com/developers/json-formatter/) - [JSON to Form](https://findutils.com/developers/json-to-form/) - [Email Signature Generator](https://findutils.com/generate/email-signature-generator/) - [Mock JSON Generator](https://findutils.com/developers/mock-json-generator/) - [HTML Formatter](https://findutils.com/developers/html-formatter/) - [JSON to README](https://findutils.com/generate/json-to-readme/)
