"He likes to send you emails to encourage you to study."

Translation: 他喜欢给你发电子邮件，鼓励你学习。

Isn't this also natural to say?
他喜欢发给你电子邮件鼓励学习。

[HashaSam]

Yeah, I think Duo should accept that as an alternative answer. :)

Is 学习 'learn' or 'study' ?

Yes.

Why not 给你送电子邮件

[PeaceJoyPancakes]

My sense is that "送" is used for a physical delivery or for a gift, and where the object is fully handed over.

"送", for its part, is often used for sending information, e.g. in the form of electronic messages. (Information is sent out but at the same time it remains with the originator.)
