trivago / Mail-Pigeon

Mail Pigeon is a mail delivery plattform, which was created in the trivago developer days (something like the Google 20% rule) to replace some of the PHP based mailing scripts that were present that days. trivago has a lot of customers and therefore the focus laid on the fast and relyable sending process of a future mail tool. We decided to build a plattform that just can send mails in a performant manner, later on we built mail pigeon on top of it.
