When I uploaded a lot of attachments through Gmail, my account got suspended for a day. So, to avoid that issue in advance, how can I know how many MB of data can I send (or save in draft) in Gmail per day?
Never heard of this either but I tried to find out what these limits are. Per their help:
I couldn't find any specific reference to a daily upload limit but did run across this lifehacker post about a firefox addon called gspace that takes advantage of the amount of storage provided by gmail. In their FAQ they mention that you can have your account suspended for 24 hrs if you pass some upload threshold. However, no specific numbers were listed.
Via Gspace's FAQ
Perhaps someone with better googling skills can track down the exact limit.
