Email that reach inboxes
SendX customers consistently achieve 95–98% inbox placement rates across Gmail, Outlook, Yahoo, and Apple Mail — backed by automated reputation monitoring, managed IP warmup, and real-time throttle adjustment.
Sender reputation monitoring
SendX monitors sender reputation across all major ISPs — surfacing blocklist events, spam complaint spikes, and bounce anomalies before they affect inbox placement.
Deliverability analytics
Track delivery rates, bounce rates, spam complaints, and inbox placement by mailbox provider — with benchmark comparisons so you always know where you stand.
Automatic IP warming
New senders go through a managed IP warmup schedule — gradually increasing volume over 30–45 days to establish a clean sender reputation across all major mailbox providers.
