Initially when I started using todoist, I gave my office email id. Now I like the todoist so much that I want to keep it even when I have changed my job.
Is there a way of changing my primary email id?
yes, you can change your primary email address. To do so, click on the gear icon in the upper-right corner and choose "Preferences". Go to the "Account" tab and you'll be able to edit your email address.
