I like that it is easy for my team members who are in different locations around our organization, but still want access from home or work remotely! It has been great so far as we use this feature at least 4-5 times per week (sometimes more).
We also love how customizable everything can be when setting up an account/sender list etc., very intuitive tool overall!! Sometimes there's some lag time between us logging back onto mailspring after being away - however if not using any other apps while logged off then usually no issues arise here either way :) Great product all round though would highly recommend considering both their mobile app AND desktop version which will help ease out many of those "offline" moments where they're working hard & need quick replies via text message / chat instead ;) Email signature management makes life easier too especially having multiple people doing similar jobs within one department such as Marketing Team Members across various departments throughout HQ office space, allowing.
