IP Blacklist & Sender Score

We constantly monitor IP health by ensuring you are alerted when it is listed in a blacklist or its sender score has dipped. You no longer have to spend hours checking different tools to know your IP health.

Email Hard Bounce & Deferral

Increase in hard bounce and deferral percentage will negatively impact your inboxing and deliverability. Our alerts will help you take pro-active corrective action and prevent the damage from happening.

Unmask Bad Senders: IPPools & Sub-Accounts

ESPs and big volume senders may have thousands of sub-accounts and IPs. Group them using sub-account labels and IP-Pools and setup smart alerts based on your criticality and customer priority.

Email ISP Alerts

You may be facing major inboxing issues on a specific email ISP (gmail, yahoo, aol, outlook etc) while having reasonably good overall deliverability. SendPost uncovers such issues and alerts you on them.

Notified on Slack & Email

Get your team notified when a deliverability alert gets triggered or when it gets resolved - on slack or over email.
