Can I get “whitelisted” from Google/Yahoo/Microsoft so all my emails go to the inbox?
No. In ancient email times, when there wasn’t so much mail and our biggest worry was being addressed as “Dear Beneficiary,” whitelisting was a way to distinguish legitimate correspondence from scams. In today’s world, where literally billions of legitimate emails are sent per year and many of them are unwanted, marketers must follow basic requirements and best practices in order to have a good reputation and reach the inbox.
