No 3 E Phrygian
Study the intervallic structure of the phrygian mode. Jam on Em7 AND E7(!!) backing tracks and LISTEN to how each note sounds on that chord. Pay particular attention to the b2 interval, which is the defining factor of this mode.
This scale holds many more chords than these, with extensions, inversions and every voicing on the neck. Find them all in Fretly
