Email Sender Reputation

Email sender reputation is an assessment that mailbox providers use, among other signals, when deciding how to handle incoming messages from a sending domain or infrastructure. Factors may include authentication, complaint patterns, invalid addresses, and suspicious sending behavior. A landscaping company that emails appointment updates and promotions should not treat every missed delivery as a reputation problem; configuration errors or recipient-side filters can also be involved. Healthy lists, accurate sender details, and sound authentication support a responsible sending program. Reputation is not a single universal score visible across all providers, and a good reputation does not guarantee inbox placement for every message.
