Please note that the transmission rate for our SMTP servers are set to a maximum of 30 emails per minute. This is in line with Microsoft's best practices.
This setting is in place:
- To reduce the risk of our domains being Blacklisted.
- To maintain excellent quality of service to all our clients, by exercising control over the consumption of server resources and bandwidth in our Exchange environment.
To send emails in bulk, we would recommend using a third party SMTP provider such as MailChimp.
