How is sender reputation calculated?

Mailbox providers consider several data streams. These include spam complaints, bounces, invalid addresses, volume spikes, engagement patterns, authentication pass rates, and content signals.

They combine these into dynamic trust scores that shift daily.

Sender reputation is built from every voyage your messages make and every reaction users have.
