Somehow when i send emails from cocrete5 cms its not rendering correctly in gmail.It removes a complete style tag but the behaviour is not cinsistent.
This is my email template. I tried this hmtl in mailchimp, sendgrid, phalcon framework with swiftmailer and the output was okay everywhere in all platforms (gmail, safari, outlook.. etc).

I also marked where the style tag disappeared.There was another case when the style tag was there but there was extra space in some of the attributes like max-width: 1 80 px;
Thank you for the help!
