Mailbird does not impose any limitations on the amount of email data which you can store inside it. In other words, there is no limit on the size of your inbox within Mailbird.

However, it is important to note that the your email account provider will set its own limits for the size of your inbox - for example, Gmail and Outlook have a limit of 15GB per email account as standard.

If you have any questions regarding your email account's size limit, you should get in touch directly with your email account provider so that they may help you further, but for any other questions which relate to Mailbird, please feel free to contact our Customer Happiness Team by clicking here.
