Find out before your customers do
Bounce rates spike. Complaint rates creep toward the threshold that gets your account suspended. Sending quotas fill up on a Friday afternoon. Without alerting, you find out when someone reports a problem. SendOps watches your SES metrics and tells you the moment something needs attention.
The problem
Bad reputation is easy to build and hard to undo
Every bounced email and every spam complaint chips away at your sender reputation. ISPs track it. Amazon tracks it. And once it's damaged, recovery takes weeks — if your account isn't suspended first.
Amazon puts your SES account under review at a 0.1% complaint rate or a 5% bounce rate. They don't warn you at 0.08%. There's no yellow light. One bad list import, one misconfigured suppression list, one campaign sent to stale addresses — and your entire sending capability is at risk. Not just the channel that caused the problem. The whole account.
While your account is under review, Amazon may throttle or pause your sending entirely. Password resets stop going out. Onboarding emails don't arrive. Transactional email your business depends on goes silent — because of a marketing campaign that went wrong three days ago.
