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 Sendgrid transaction data. Transient SMTP errors show reputation issues long before IPs are blocked.

By connecting Sendgrid's webhook endpoint to Postmastery's Delivery Analytics, you will have in depth delivery visibility in seconds and you will have deliverability insights via an online dynamic dashboard to view reports. You will also receive alerts by email in case of delivery issues. In addition, Postmastery's team of deliverability experts is available to provide support where needed. Please note, that in case Sendgrid’s endpoint is already in use, Postmastery offers a webhook forwarder to create one other endpoint to retrieve similar data.

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.
