Verizon overview

Verizon Communications (Verizon) was created in June, 2000 when the telephone companies Bell Atlantic and GTE merged and combined operations. Verizon and its subsidiaries comprise one of the largest communication technology providers in the world with over 160,000 employees. 

In June, 2015, Verizon acquired America Online (AOL) for AOL’s digital content and video advertising platform. As of October, 2016, email accounts have been transitioned onto the AOL email infrastructure. 

In July, 2016, Verizon agreed to acquire Yahoo! For Yahoo!’s digital content and mobile user footprint. Once the acquisition is complete, it is expected that Verizon will combine the email infrastructures for Verizon, AOL and Yahoo!. Early reports suggest the new email platform will likely resemble Yahoo!. 


Verizon domains are handled by AOL’s email infrastructure. AOL has a robust postmaster site with additional information on sending to their servers.

Return Path partnership with Verizon

Verizon partners with Return Path through AOL’s use of Return Path’s Certification Whitelist. Senders participating in in Return Path's Certification program receive preferential treatment at Verizon. 

Verizon delivery mediation

Verizon does not have a public postmaster page. However, AOL has a public escalation process, which allows senders to open a trouble ticket, submit a feedback loop request, or submit a whitelist request. AOL also has extensive information about the error codes they return available on their Postmaster website. 

Return Path guidance

Return Path understands AOL well and may have data to diagnose deliverability issues. Refer to AOL’s deliverability best practices and postmaster page for additional details on improving deliverability at Verizon.
