Your email account includes 250 SMTP relays per mailbox, per day. Each address listed in the CC and BCC fields count against your daily limit. One relay consists of an email message sent to one address using the SMTP service. Therefore, you can send up to 250 messages per day, per mailbox. Your SMTP relay limit resets once each day, approximately every 24 hours.

If you need more than 250 relays for your mailbox, you can purchase additional relay packs (in packs of 50). You can use a maximum of 500 SMTP relays per day, per email account. If you want to use more than 500 relays per day, you can distribute SMTP relays across multiple email accounts.

The SMTP relay service is provided to you as a feature of your email account. This service is not set up by default. You must set up the service when you configure your email account settings.
