This post is about file-sizes. If you’re looking for guidance on Mailchimp image dimensions, please see the separate post.
The Content Manager in Mailchimp shows the images and files that you’ve uploaded to Mailchimp. Any files, including images, that you’ve uploaded are shown in the Content Manager for simple reuse in future campaigns.
Allowed Mailchimp file-types
There are many file types that may be uploaded and stored in your Content Manager. The file-types allowed to be uploaded to the Mailchimp Content Manager are:
|Text files||.txt, .csv, .log, .css, .ics|
|Image files||.jpg, .jpe, .jpeg, .gif, .png, .bmp, .psd, .tif, .tiff, .svg, .indd, .ai, .eps|
|Document files||.doc, .docx, .rtf, .odt, .ott, .pdf, .pub, .pages, .mobi, .epub|
|Audio files||.mp3, .m4a, .m4v, .wma, .ogg, .flac, .wav, .aif, .aifc, .aiff,|

Tip: A file attachment cannot be sent with an email campaign. A link to a file in the Content Manager may however be sent which acts in a very similar way to sending an attachment. See instructions on how to link to a file (in place of an attachment) in Mailchimp.
Maximum Mailchimp file-sizes
The maximum file-sizes that may be uploaded into the Content Manager are:
- 1 MB for images (e.g. .jpg)
- 10MB for other allowed file-types (e.g. .pdf)
