What's the best tool/hack for sending our behavior based emails?

I'm looking to send out personalized emails similar to airbnb, which are triggered by users interactions on our site. There are so many options with prices all over the board, I'm a bit overwhelmed and would like some advice. I see existing mail platforms (i.e. sendgrid, Vero, mailchimp, etc) with options, but then again am seeing Mixpanel also with some options. Would love your feedback, thank you!
