Yesterday I did a talk at Xing offices in Barcelona. It was about some tips on how to send emails massively from a Ruby on Rails application without being tagged as a spammer by Hotmail, Gmail or Yahoo. I’m not a dedicated expert on this, but I’ve been learning these things while developing last internet site, and I thought it may be also interesting for other developers.
Here are the slides (in english) of the presentation, formerly named “Massive emailing with Linux, Postfix and Ruby on Rails“.
Here is the PDF for downloading.
