CISG-Advisory Council Opinion No. 1, Electronic Communications under CISG:

[. . .]

CISG Art. 16(1) [. . .]

OPINION In case of electronic communications the term “reaches” corresponds to the point in time when an electronic communication has entered the offeree’s server. An offer may be revoked if the revocation enters the offeree’s server before the offeree has dispatched an acceptance. A prerequisite is that the offeree has consented, expressly or impliedly, to receiving electronic communications of that type, in that format, and to that address. In electronic communications the term “dispatch” corresponds to the point in time when the acceptance has left the offeree’s server. The offeror may revoke the offer by sending a revocation that enters the offeree’s server before the offeree’s acceptance leaves the offeree’s server. A prerequisite is that the offeror has consented, expressly or impliedly, to receiving electronic communications of that type, in that format and to that address.
