Comcast mail is migrating to Yahoo. If this news comes as a surprise, you haven’t been informed yet. Since June 2025, Comcast subscribers have been receiving notifications that their mail will be accessed on Yahoo servers. Xfinity assures customers that their comcast.net email addresses, messages, folders, and contacts will remain unchanged. These migrations will be completed throughout 2026, so don’t worry if you haven’t received your notification yet.
Key Details of the Migration
- Email Access: After the migration, users will access their @comcast.net email through Yahoo Mail’s platform.
- Account Notifications: Comcast will notify users via email about 30 days before their specific migration date.
- Account Management: Users must sign in at login.yahoo.com using their full @comcast.net email address and password to complete the migration.
What Happens to Your Data
- Migrated Data: All emails, contacts (up to 10,000), and folders (up to 4,100) will transfer automatically.
- Exceptions: Emails larger than 25MB will not migrate unless deleted beforehand. Folder names over 240 characters will be shortened.
Post-Migration: After migration, users will need to update their email settings on devices or apps to reflect Yahoo’s configurations.
Opting Out: Users can opt out of the migration, but this will result in the closure of their @comcast.net account and permanent deletion of all data.
