Deliverability shows signals that can affect whether mail keeps reaching inboxes. Use it when failures rise, when you add a provider, or when volume changes.
Managed Amazon SES is for transactional email only. Use your own provider for marketing, newsletters, or bulk promotional sends.

Summary

The summary highlights 24-hour bounce rate, 24-hour complaint rate, and provider signals. Sendmux warns near:

​
Risk signals

Risk signals compare activity across three windows:
  • Last hour.
  • 24 hours.
  • 7 days.
Use this table to separate short spikes from sustained issues. A high one-hour rate may be a bad campaign, while a rising 7-day rate points to a broader reputation problem.

​
Provider health

Provider health shows the current monitored provider status, impact, and 24-hour bounce and complaint rates. Amazon SES appears when managed provider signals are available.
