Recommending entire volumes of poetry seems to me daunting: poetry is so dense. Single poems, however, allow you to nibble on a new poet and see if you enjoy the flavor.
To start, let me recommend the astonishing Third Elegy from Rainer Maria Rilke's Duino Elegies, a beautiful and terrifying description of the depths stirred in us when we love.
Here are two translations:

Oh, that poem's beautiful.
A favorite of mine is Miniver Cheevy by Edwin Arlington Robinson

I had forgotten that one. Funny, and with that wonderfully Dickensian name.
For some reason it brings to mind Louis MacNeice's Bagpipe Music.
