Can ESPs whitelist senders at mailbox providers?
Myth: False. ESPs cannot whitelist senders at mailbox providers. **Gmail**, **Microsoft**, and **Yahoo** control their own filtering. No **ESP** has authority to bypass provider filtering decisions.
ESPs may have relationships that provide feedback or issue resolution channels. These are not whitelisting privileges.
Earn **inbox placement** through good sending practices. There are no shortcuts through **ESP** relationships to bypass provider filtering.
