Unfortunately, I coudln’t find a way till now to show the left storage space for a Mail Address. So i hope to get some answers here
Before Switching to Mailspring is was using Thunderbird. When clicking on a Mailadress the percentage of exhaustion of that account was displayed in the bottom right corner. Also, in the settings, you could check how much storage space is left.
Is there Anything similar in Mailspring?
Sending love and blessings
