Send a link -- yes; that's the design purpose of the service.
You upload files (BIG file sizes are welcomed).
You email the link to the BIG file.
No concerns over the file being too big to attach to an email.
Most contemporary email services/clients are good for attached files up to 20 to 25 MB.
There are still many that will only move on an email with attachments no more than 15 or 10 MB.
It could be less.
SO - Adobe Send.
Park that 100Mb file in the space provided.
Send the email with the link.
"Send" tracks and records the "go out" and the receipt.
In short the service emails a link to the file(s) and does not attach the file(s) to an email.
No more bounced / rejected emails due to attachment(s) being to large.
Be well...
