Most senders have discovered data sources such as blacklists, sender reputation, and inbox monitoring. But many are not aware how much information is hidden in their internal transaction data. Transient SMTP errors show reputation issues long before IPs are blocked.

Detailed bounce responses reveal why delivery rates are low. The platform processes SMTP delivery data from on-premises mail servers and SMTP providers.

Email addresses are pseudonymised or anonymised so your data remains secure. It also reads data from Microsoft SNDS, Return Path Sender Score, Google Postmaster Tools (GPT) and relevant blacklists. There’s no need any more to manually check a collection of deliverability tools.

Users can access an online dashboard to view reports. They also receive alerts by email in case of issues. In addition, our team of deliverability experts is available to provide support where needed.

"We're able to monitor the delivery of emails for thousands of our users. We've been able to reach a global delivery rate of 98% solely thanks to Postmastery."
