How many messages can be sent out per day?
The number of email messages that can be sent from a single mailbox is 250 messages per hour and not exceeding 500 per 24 hours. For sending messages above this limit, we recommend using a mass mail service dedicated to sending large quantities of mail.
Please note that sending large numbers of email that result in excessive bounces or complaints, or that appear to be spam-like, may result in a suspension of email services.
