Deliverability & Alerts
Catch deliverability issues before your customers do
Monitor bounce rates, complaint spikes, and sending limits in real time. Get instant notifications delivered straight to Slack, email, or webhooks the moment something needs attention.
The problem
Domain reputation is fragile without real-time monitoring.
A sudden spike in bounced emails or spam complaints can quickly harm your domain reputation and trigger sending throttles or account reviews.
Without proactive monitoring, teams only find out about deliverability problems when users complain that password resets or notifications aren't arriving.
SendOps tracks your deliverability metrics around the clock and alerts your team immediately, so you can resolve issues before they impact your application.
