Both your SmartSeeds data and your Certification data come from interactions with Microsoft, but they represent different points in your email campaign’s path to the recipient.
The data you receive from Microsoft in Certification represents metrics based on global filtering at the Microsoft gateway: whether your email campaign is blocked, filtered immediately into your Junk Email folder, or allowed into the inbox. This filtering is heavily dependent on your reputation as an email sender.
Microsoft SmartSeeds help you understand relative engagement by using advanced analytics to illustrate how placement is impacted by subscriber engagement with your mail and the mail of others. The engagement factor is critical to understanding how your emails are being placed after subscribers have started to engage with them: whether subscribers mark as read, for example, or delete without reading.
Multiple signals are used to create a full picture of your email marketing program and can indicate areas that may need improvement.
