Do ESPs control inbox placement?

Myth: False. ESPs transmit mail but do not control **inbox placement**. Placement decisions are made by receiving mailbox providers based on **sender reputation**, authentication, content, and engagement.

ESPs influence delivery through infrastructure quality and sending practices. But the final placement decision belongs to **Gmail**, **Microsoft**, **Yahoo**, and other receivers.

Understand ESPs deliver mail; providers decide placement. Good **ESP** infrastructure helps but does not guarantee specific outcomes at receiving systems.
