Yes – the Mail Designer API lets you fill placeholders in your designs and send emails automatically. For instance, you can send personalized messages to customers straight from FileMaker.

Use the Template ID to target a specific design. You’ll find the Template ID in the Placeholder Inspector: simply select a placeholder in your design and copy the Template ID from the bottom of the sidebar.

Each Mail Designer plan includes a monthly allowance of “stamps.” One stamp is used per email sent to an individual recipient—for example, sending to an audience of 10,000 requires 10,000 stamps.

When using the Mail Designer API, each delivery counts as 25 stamps.

Example: The “Paris” plan includes 15,000 stamps per month, which allows for up to 600 API emails.

With Mail Designer 365, that’s a thing of the past. Design updates can be made anytime directly by your marketing or design team—no developers, no coding. Your API or FileMaker solution simply references the Mail Designer template ID. Just open Mail Designer 365, make your changes (logos, texts, seasonal elements), save—and you’re done. That’s modern, efficient collaboration.
Absolutely. The API integration (from your web scripts or a FileMaker solution) only links to the Mail Designer template ID, so you can change the design anytime—logos, texts, seasonal styles—without touching a single script. Just edit in Mail Designer 365 and save. Done.
