In Constant Contact, you cannot attach documents to an e-newsletter per se. However, they can be hosted online and then linked to your email. This allows your contacts, who may not  have compatible software, to read it and also keeps a large file size from making your email undeliverable.

You have a few options for hosting your files online:

• Constant Contact – Upload any PDF, Word document, Excel file or PowerPoint presentation to MyLibrary.
• Your Own Website – Upload your file to the web and host it on your own website, or ask your Webmaster to do it for you.
• Third Party Service – Upload your file to the Internet with a third party file hosting service, such as Digioh or Google Drive.

Once your document is hosted, you can insert its URL into your email.
