What people say about LeanMail

What is LeanMail Duo and Shared Inbox?

LeanMail Duo allows you to share all the features of LeanMail with your assistant or boss, respectively.

LeanMail Shared Inbox allows teams to keep track of exactly who is doing what and when. Ensure that your A-customers are responded to first and allow your teams to monitor themselves without having someone to delegate emails. Our customers claim that they have an average time-savings of 70%.

Who is LeanMail Duo and Shared Inbox for?

LeanMail Duo is for executives with personal assistants or any two-person team.

LeanMail Shared Inbox is for teams that use a common inbox and are tired of all the confusion and lack of efficiency connected with working in a shared inbox environment.

Why do you need it?

During the past 25 years, there has not been any real attempt to bridge the challenge of working as a team in one particular inbox. Until now.

Most companies that use shared or common inboxes complain about not being able to collaborate efficiently:
– They don’t know if another person is attending to an email
– There is no way to ask questions of other teammates directly in the inbox regarding individual emails
– Assigning emails using categories eliminates the ability to use categories for other purposes
– Several people read the same emails over and over again, wasting precious time and resources
– Mails are forgotten or not answered on time

LeanMail Duo and Shared Inbox puts an end to those and many other problems.

The Leanmail Journey

Why beginning the LeanMail journey with LeanMail Duo or Shared Inbox training is a brilliant idea.

The main reason for beginning your journey with either of these solutions is because you will be able to delegate emails without having to forward them. Another excellent reason is that you will be able to communicate to each other what you are doing about any email and when you expect to reply to the sender or finish the task.
