Hey there!

I have been trying to use Gmail's API to send responsive HTML templates inside email, but I realized that email clients are stripping away <style> tag from email which is causing responsive styles to break. I have tried adding them in <body> and <head> tag as well but nothing seems to be working for me. I noticed that PutsMail is able to retain the <style> tag in <head> but I'm unable to understand how can it be done.

Any help will be appreciated.
