Photo app on MacBook
How do I send a large photo album in an email? Or can I have a link to my album to share it?

You can't send a large album. Most email services limit the size of an email to quite a small amount.
If you are staying in the apple eco system, you can create a shared album, and generate a web link to the shared album. The problem with shared albums is that you can only share reduced size/quality images, and most of the metadata is stripped out. (so DONT use shared albums to store your master files).
If that works for your use case (eg just sharing with friends for online viewing) then is is not a bad solution. It is no good for transferring your images in any situation where full quality is needed. For that you'd have to choose some alternative sharing facility.
Although - if you just want to share files (with no presentation needed) you can put them into an iCloud drive folder, and share that. Assuming you have enough iCloud space.
