Members are notified of everything that matters: outbid, won, sold, unsold, ending soon, new questions and answers, offers, messages, payments, shipping, feedback and approvals - in their account and by e-mail.
The outbid e-mail is the most powerful marketing tool of an auction website: it brings a motivated bidder back within minutes. PHP Bid sends it automatically for every auction.
All e-mails use a clean branded layout with a button to the right page, and are sent through a queue so pages stay fast.
In-site notifications give members a timeline of their activity, even if they turned some e-mails off.
