Hi there, Thank you for reaching out. From what I understand, you are trying to attach the XD file into MailChimp campaign. We can upload the file in Mailchimp using these steps mentioned below:- 1. In the Content section of the campaign builder, click Edit design. 2. On the Design step, click an existing text content box or drag and drop a new one into your layout. 3. Create the text you want to link and highlight it. 4. Click the Link icon. 5. Click the Web Address drop-down menu, and choose File. 6. Click Upload to choose a file from your computer. 7. Choose your file, and click Open to upload it to the Content Manager. 8. The URL of your uploaded file will be automatically added to the Insert or Edit Link pop-up modal. 9. Click Insert. Please try these steps and let us know if that helps. Thanks, Harshika
