Will a 24MB PDF send on all email platforms?+
It will send on Gmail and Yahoo Mail (25MB limit) but not on Outlook.com (20MB limit). Compress to under 20MB to cover all platforms.

Email attachments are base64-encoded in transit, which increases the actual size by about 33%. A 25MB file becomes ~33MB encoded, exceeding the limit.
