in contract law
The sending of an acceptance or other message. An acceptance sent by mail or similar means from a distance is operative upon dispatch only if properly addressed and accompanied by the precautions ordinarily observed to ensure safe transmission of similar messages. When an acceptance is seasonably dispatched but the offeree uses an uninvited means of transmission or fails to exercise reasonable diligence, it remains operative upon dispatch if received within the time a properly dispatched acceptance would normally arrive.

How it applies
Common Examples

Improper Address Blocks Dispatch
Dustin Donovan mailed an acceptance to Duarte Shipping but used an outdated corporate address listed on an old letterhead. The letter never reached the correct office. Because the acceptance was not properly addressed, it did not become operative upon dispatch and no contract formed when the letter was sent.
Uninvited Courier Still Timely
Denise Donovan sent her acceptance of Delta Dynamics' offer by overnight courier instead of the invited first-class mail. She failed to include a tracking number. The acceptance arrived within the normal mail window, so it was treated as operative upon dispatch despite the uninvited method.

Common questions
Frequently Asked
3
When is an acceptance operative upon dispatch under the mailbox rule?+
An acceptance sent by mail or similar means is operative upon dispatch only when it is properly addressed and the sender takes the precautions ordinarily observed to ensure safe transmission. If those conditions are not met, dispatch alone does not create a contract.
Supporting sources
Does using an uninvited transmission method prevent an acceptance from being operative on dispatch?+
No. When an acceptance is seasonably dispatched but the offeree uses an uninvited means or fails to exercise reasonable diligence, the acceptance is still treated as operative upon dispatch if it arrives within the time a properly dispatched acceptance would normally have arrived.
Supporting sources
What happens if an acceptance is not properly addressed?+
The acceptance is not operative when dispatched. Proper addressing is a prerequisite for the mailbox rule to apply, so a misaddressed acceptance does not form a contract at the moment of mailing.
