SaneBox works with any email service that provides IMAP, EWS/OWA or Active Sync such as Yahoo! Mail, Gmail, AOL, Mobile Me, MS Exchange and many others.
Does SaneBox work with my email provider?
Services that provide only POP , such as like Earthlink and Comcast, are not supported by SaneBox. If your client is using POP to read mail, then you won’t see your new Sane folders.
