How replies work
- A business day is Monday to Friday, US Central Time, not counting US federal holidays.
- A reply is a person's answer, not an automatic acknowledgement. It may say what is known so far and when the next reply will come.
- During exam weeks a reply can take up to two business days longer. The mailbox sends an automatic notice saying so; the reply itself still comes from a person. An export or deletion still finishes within seven days.
- There is no phone line, no live chat and no uptime guarantee.
Before you write
Many setup questions already have an answer in the FAQ. If you write about a problem, say what you were doing, what you saw, and which browser you use.
Please don't send a password, a Todoist token or a calendar feed address. A feed address works like a password: anyone who has it can read the calendar. The feed address guide explains why.
