Is there a limit in the size or quantity of emails to task it can handle
Every project in Todoist (including the inbox) can have a total of 150 tasks on free accounts and 200 tasks on Premium accounts.
Also, on a free account you can have a total of 80 projects and on a Premium account - 200 projects.
So with the pay version I can have 200 task for each project or a total of
200 task in all projects?
With Premium, you can have 200 projects and 200 tasks in each project for a total of 40 000 active tasks on your account.
With a free account, it's 80 projects with 150 tasks in each project for a total of 12 000 active tasks on the account.
Do the "Archived" projects count towards the 200 x 200 or 80 x 150 limitation?
No. Any archived projects along with its tasks do not count towards the limitation that's mentioned by David. Only active projects and tasks. :-)
Thank you for your reply. :) :)
