I like that it's easy for me as my inbox can be easily managed with one place instead of having multiple emails in different folders or labels which would make things difficult when trying find something at times! It also helps keep track of all communication between usernames so we don't have any confusion about who has what information from our business communications. Nothing really but just minor issues here & there such as not being able to add more than 1 folder per account (I understand this may change down future releases). We use boxberry mainly because its quick access via mobile app allowing you to quickly send messages without needing your computer always available - great if working away etc where internet connection isn’t guaranteed 24/7.
