Why Can't I Include Attachments in My Newsletter?

In most cases, viruses are sent through attachments, and as a result, spam detectors are much more likely to reject emails with attachments or send them directly to the spam folder. Additionally, attachments in newsletters can slow down the sending process and impact the deliverability of your newsletter.

Here are simple ways to send files to your subscribers instead:

1. Host the file on your website and include an external link or a download button in the body of your newsletter.
2. Use external file hosting services like Dropbox or Google Drive, and include a link or button in your newsletter for subscribers to download the file (make sure the sharing permissions are public!).

Both options work with the hyperlink function or a URL block in the composer — see Working in Emails.
