You can set your default due date, time, reminders, and message to reviewers under your profile.
Click your avatar at the top right of your dashboard and select profile.
Under settings, you can change your preferred default due date and time, and also write your default message to reviewers, which shows every time you send a new proof. You can also set default reminder/s too.
You can always change these defaults during the set-up of your proof, or after the proof has been sent out (from inside the proof’s info pane).
Tip: When editing the due date you can type in a phrase to indicate what you’d like it to be. Here are some phrase examples:
“2pm next Tuesday”
“Noon on April 5th”
“Tomorrow at 5pm”
“9:05 am on Friday”
“4th of Jul”
“12 February 2019”
