What’s the history of Yahoo/AOL under Verizon Media?

Yahoo and AOL merged under Verizon Media in 2017, combining their email platforms and spam filtering infrastructure. This consolidation means both services now share reputation data, blocklists, and filtering logic. What affects your deliverability at Yahoo typically affects AOL identically.

The combined platform processes billions of messages daily, making it the second largest consumer email provider after Gmail. Verizon Media rebranded as Yahoo in 2021, but the technical infrastructure remains unified.

For email senders, this consolidation simplified compliance: one set of requirements covers both Yahoo and AOL recipients. However, it also means reputation problems affect a larger audience simultaneously. The shared feedback loop reports complaints from both platforms, requiring careful monitoring of combined metrics.
