MailGenius Alerts Marketers to Yahoo’s New Email Rules

“Authentication, list hygiene, and sender reputation are no longer optional — they’re mandatory. This is a wake-up call for every marketer who thinks they can set and forget their email campaigns,” said Troy Ericson, CEO of MailGenius. “Yahoo’s update, combined with Google’s and Microsoft’s enforcement, makes it crystal clear: inbox placement now depends on how well senders follow deliverability best practices — and how often they test for them.”
