The Certified Senders Alliance is a unique cooperation between Email Service Providers and Email Inbox Providers in the DACH (Germany, Austria and Switzerland) region and beyond. Their main goal is to improve the quality of emails being sent to recipients.

Currently, they exchange data between Inbox providers like Yahoo, Microsoft, GMX, 1&1 and United Internet and Email Service Providers. This data is then collected and plotted into graphs that help you monitor the quality of you emails:

SPAM Complaint Rate (SCR) and CSA-Volume

Connects the SPAM Complaints to the volume sent. The lower the percentage, the better. Google and Yahoo require you to keep this under 0.3% per February 1st 2024.

SPAM trap hits

Spam traps (also called honeypots) are used to identify and monitor spam email. Anti-spam organisations, Internet Service Providers (ISPs), and corporations use spam traps to lure spammers.

Opens (unique)

Displays the Open Rates against the volume sent.

Feedback loops

When a contact marks an email as spam in the web client of Yahoo, Maileon is able to identify that person and unsubscribe that contact.

The CSA is mostly active in the DACH region, but has international impact with their feedback. Find out more about the Certified Senders Alliance here.
