A.T. Robertson Commentary Revelation 1:11

"saying, What thou seest, write in a book and send [it] to the seven churches: unto Ephesus, and unto Smyrna, and unto Pergamum, and unto Thyatira, and unto Sardis, and unto Philadelphia, and unto Laodicea." — Revelation 1:11 (ASV)

Write in a book (γραψον εις βιβλιον). First aorist active imperative of γραφω for instantaneous action. The commission covers the whole series of visions which all grow out of this first vision of the Risen Christ.

Send (πεμψον). First aorist active imperative of πεμπω. Part of the commission from Christ. The names of the seven churches of 1:4 are now given, and the particular message to each church comes in chapters 2 and 3 and in the same order, the geographical order going north from Ephesus, then east and south to Laodicea. But apparently the whole book was to be read to each of the seven churches. It would probably also be copied at each church.
