How Many Emails Can You Send At One Time From Gmail? – How to solve the 550 5.4.5 Daily sending quota exceeded problem?
As an effort to prevent spammers from misusing Gmail, Google has put a max cap on the number of emails you can send from one account, from one IP.
If you are using web based GMail interface, then, the max cap is 500 emails. What ever combination you use, you’ll not be allowed to send more than 500 emails with in a time span of 24 hours.
Alternatively, if you are using Gmail via IMAP or POP, then the limit is still lesser. You’ll not be allowed to send, no more than 100 emails in a time span of 24 hours. This limit might be to prevent users from misusing the export contact feature of Outlook, using which, you can send emails from different Gmail ids!
The consequences of sending more than 500 emails are many and varied and hence you’ll have to be really careful when you plan to send out so many bulk emails!
