We even track clicks for your file in the campaign report. In this article we walk you through how to host and delete files in your MailChimp account, provide info about the types of files we can host, and also offer some insights into why hosting files has more to offer than using traditional attachments when sending bulk email.

What file types can I upload?
There's a 10MB limit for individual files in your MailChimp gallery. We recommend images be under 1MB if you're displaying them in your campaign to ensure subscribers can download and view them quickly.
While we accept all file types for upload, we'll also inspect each uploaded file and change extensions to reflect the original format if necessary. For example, if you're working with a JPEG image type, but rename or save it using a .png extension we'll detect the original file type and change it back to JPEG automatically when the file is uploaded.

Why MailChimp doesn't allow attachments
There are a number of reasons attaching files to bulk emails can cause problems.
- Many ISPs and end-users block emails above a certain size. Attachments can increase the size of your email raising the risk of your email getting blocked.
- Most content and virus scanning programs see attachments sent through any bulk mailing service as a potential security threat, and either block the attachment or the email entirely. So a majority of attachments may not reach your subscribers.
- Sending a copy of your file to each recipient would take a lot of bandwidth, which can get pretty expensive. Hosting files for you instead of allowing for attachments helps keep costs down and allows MailChimp to offer things like our Forever Free plan.
Hosting files instead of allowing attachments helps keep costs down and helps delivery rates, which means a win for everyone. Plus, you'll be able to track which recipients click the link for your file, and how many times.
