Sender identity is the combination of From, authentication, and reputation signals. Learn what shapes sender identity.
Sender identity is how both recipients and mailbox providers interpret who is sending a message. It includes visible branding (From name), technical identity (SPF/DKIM/DMARC), and reputation.
When identity is consistent, inbox placement improves and recipients trust messages more. Inconsistent domains, changing From names, and mismatched tracking links can weaken identity.
