I don't want to speak for MailChimp (read their blog post for that).

But basically, they like TinyLetter. TinyLetter likes MailChimp (srsly, the email business can be slimy as hell but they're totally legit, upstanding, & everyone knows it). TinyLetter has a good brand and a decent amount of users (roughly 500,000 people subscribed to 30,000 newsletters). Both companies recognize an opportunity that we think is large, and buying TinyLetter gives them a head start.

I'll be helping advise TinyLetter for a while, and we both really wanted to work together.

So basically, for these reasons and more, it just "made sense," if that makes sense.

Yep, that makes sense :)
