To assign an email to someone, you must first add it to a project and make sure that the person has joined that project. You can not assign emails which is not a part of any project.
Step1 – Add it to a shared project.
Step 2 – Click assign.
Step 3 – Select a person to assign.
Once someone assigns you to an email, you’ll see a notification at the Mailflow icon. You will also be notified every time someone makes a change in the sidebar next to the email thread.
Emails you have been assigned always appear in your inbox when they get a reply. Even if you are not a recipient.
Tasks from the email thread will be surfaced in your inbox sidebar and in your personal task list for easy access.
