A computer implemented method for tracking bulk email can include configuring, by a bulk email client, a bulk email, wherein the bulk email includes an initial email and identifies a plurality of recipients. The method can further include iteratively executing by the bulk email client after the configuring, a sub-method until either a marked email corresponding to the bulk email is prepared for each recipient in the plurality of recipients or a request to cease continuation of processing the bulk email is generated in response to user input at the bulk email client. The bulk email client displays a graphical user interface that shows a selectable interruption element that, if selected, terminates or pauses prior to completion of a current or next iteration.
