There is a file upload limitation. However, we are investigating the actual limit. Your investigation ticket ID is EMAILAPP-291. We’ll notify you in case of any update.

I wish to migrate from Thunderbird to gmail. There are about 10 gigs of files. Which of your products can do that, and how much does it cost.
Thank you.
