Gains popularity: over 60,000 tests run
Litmus takes over PutsMail, continues development
PutsMail was originally developed by Pablo Cantero, a software developer based in São Paulo, Brazil.
Pablo experienced first-hand the difficulty of sending HTML emails to himself for cross-platform testing. He built PutsMail.com to help others in the same situation and email designers around the world loved it.
In 2014, Litmus purchased PutsMail and took over its development, continuing to offer it as a standalone free tool for email marketers to perform quick tests of their campaigns.
