Can Mailchimp send a PDF attachment?

Mailchimp does not support attachments in campaign emails. Upload the PDF to Mailchimp’s content studio (or host it elsewhere) and put a download link or button in the email instead.

Common follow-up questions

Is there a file size limit?

Mailchimp lists current upload limits in its help docs. Keep lead magnet PDFs small anyway so they open quickly on phones.

Why not just attach the PDF in a normal email?

Attachments in bulk email are often filtered or blocked; a link is the standard approach.
