By default the system writes back an individual "email sent" activity for each contact in a mailing.
If you prefer the system to write back a single "email sent" activity and link the contacts in the mailing this can be enabled at a system level.
Please contact your Customer Success Manager or Vuture Support who can enable this at "Admin.System.InterAction.Combine Merge Send Activities"
They should update the setting "Admin.System.InterAction.Activity API timeout" from the default of 10 seconds to 120 seconds. This is to handle writing back the single email sent activity which will be a larger request because it contains all of the ContactIds of the the recipients for that send.
Writing back a single activity reduces the volume of activities created in your InterAction and makes it easier if you need to modify or remove the activity.
Writing back multiple activities has the advantage of logging for each contact the time that their mail was added to the sending queue.
Will writing a single activity speed up my email sends?
Although individual activities are not written we still need to make a call to InterAction to link each contact to the single activity so the net result is similar - there may be a small overall improvement.
Can I apply this retrospectively to previous email send activities?
Unfortunately this not possible.
