What to do when outgoing emails from the B2C Commerce platform have been blocked by email providers

This situation typically occurs when there is a large volume of emails going out in a short period of time e.g. during a sale event. The surge of emails is seen by email providers as spam and they block you. 

Option 1
Please contact the email provider directly. An email company usually has a division that deals with emails getting blocked for abuse. You want to go to their website and find a link to this division where they have posted instructions on how to get your email unblocked.

Option 2
Consider utilizing the functionality outlined in the Business Manager Email Configurator documentation to configure the platform to utilize your SMTP server of choice. In addition, please also review the articles below:

• Sending emails through the B2C Commerce platform's email (SMTP) server

Option 3
For Hotmail / Outlook, consider joining Smart Network Data Services and the Junk Mail Reporting Program (JMRP) program to manage the Business Manager Production IP (sender IP) at Microsoft.
