A method of controlling issuance of alerts involves a server receiving notification of occurrence of an event at an account, saving in an events history the event occurrence, receiving device information from a mobile device associated with the account, and determining a position and/or speed from the device information. The server maintains at least one event definition defining particulars of suspension of notifications of events at an account. Upon the position or speed correlating with one of the event definitions, the server saves in the events history an occurrence of at least one additional event occurring at the account subsequent to the event, and suspends notification of the saved occurrences to the mobile device. The server transmits to the mobile device a notification of the occurrences saved in the events history and clears the events history upon the position and speed no longer correlating with any of the event definitions.
