Tracking & suppression

Opens and clicks are tracked on any email provider. Automatic bounce and complaint suppression, described below, requires Amazon SES — see Email providers for the full comparison.

Opens & clicks

A tracking pixel records opens via GET /t/{recipientId}. Links are rewritten through Plume to record clicks before redirecting, via GET /l/{linkId}/{recipientId}. Both can be disabled per campaign for privacy-first sends. This works the same regardless of which email provider is active.

Bounces

SES only

Automatic bounce tracking requires Amazon SES. SES reports hard and soft bounces through the /webhook/ses SNS feed. Hard bounces are suppressed immediately; soft bounces are retried before suppression. If you send through SMTP instead, watch your provider’s own bounce dashboard — see Email providers.

Complaints

SES only

Automatic complaint tracking also requires Amazon SES. When a recipient marks mail as spam, SES sends a complaint notification over the same /webhook/ses feed. Plume suppresses the address and records the event against the campaign.

Auto-suppression

Caution

Hard bounces, complaints, and unsubscribes are auto-suppressed. Suppressed addresses are never emailed again, across all campaigns, until you explicitly remove them — suppression is enforced at send time. This is the single most important safeguard for staying out of spam folders. Automatic bounce/complaint suppression works with SES only today; unsubscribes are suppressed on every provider.
