Sender deliverability<\/p>\n\n\n\n

Register and build your sending reputation<\/h1>\n\n\n\n

Mailbox providers do not offer a universal IP registration or guaranteed inbox placement. Their sender portals help you verify ownership, monitor reputation, receive complaint data, and correct delivery problems while your domain and IP earn trust through legitimate email.<\/p>\n\n\n\n

\n

Before registering<\/h2>\n\n\n\n

Complete the SMTP Server for WordPress DNS and server checks first. Your sending hostname must resolve to the sending IP, the IP\u2019s PTR must resolve back to that hostname, and SPF, DKIM, and DMARC must validate. Registration cannot compensate for missing authentication.<\/p>\n<\/div><\/div>\n\n\n\n

Google Postmaster Tools<\/h3>\n\n\n\n

Add the domain used by your DKIM signature or SPF Return-Path. Google discovers associated sending IPs from authenticated Gmail traffic. Low-volume senders may not immediately see dashboard data.<\/p>\n\n\n\n

Microsoft SNDS<\/h3>\n\n\n\n

Request access to each public sending IP you control. Smart Network Data Services shows Outlook.com reputation data and includes the Junk Email Reporting Program for recipient complaint reports.<\/p>\n\n\n\n

Yahoo Sender Hub<\/h3>\n\n\n\n

Add and verify your DKIM signing domain, then enroll it in Yahoo\u2019s Complaint Feedback Loop. Complaint reports help you suppress recipients who mark messages as spam.<\/p>\n\n\n\n

If you operate a different server or send for a different domain, register the domain and public IP shown by your own SMTP Server for WordPress installation.<\/p>\n\n\n\n
