I frequently add emails as tasks and would like to be able to filter my email to see those that are tasks. Is there any way to do this?
Would be nice if pushing the Add button would automatically add a Todoist label to the mail. That's is what I do manually at the moment.
It is actually possible to do so, but it's more of a workaround than a specific feature. Each time you add a task from an email, it contains some hidden code pointing to this message. In case of Outlook, searching for the word "outlook" will show you all tasks added this way and similarly, in case of Gmail, you can search for "mail.google" and all tasks added via Gmail will match this query.
You could save a mail.google query as a filter and use it to show only these tasks.
It's more the other way around I am looking for i.e. from gmail can I see all emails that have tasks associated with them.
Oh, sorry for the misunderstanding. That's indeed not possible, we may consider Pascal's suggestion in the future as far as it's possible and configurable (as not everyone would want to have labels added to their emails this way).
I agree with Pascal's suggestion to have the ability to add a "Todoist" Gmail label to an email after it's added as a to-do item. The use case for me is that I'd like to mark my emails as read once I've added them to Todoist, but I'd still like for them to not get lost in my inbox - which is much easier to do with a label than re-marking them as unread.
