After searching awhile, I found they are classes added by Modernizr. It’s said that these classes are harmless in html pages. But does this affect the mail? You know, nowadays google filter is quite restrict, a email with heavy html code my end ups in the promotion tabs ☹ how to remove them?

Right now is hard to not be in the promotion tabs.

Because I think this is my personal opinion that Google, Outlook and other have been flag Amazon SES, Sendgrid, Sparkpost and many other as Email Services Providers.  
I came to this conclusion since was using Sendgrid for our internal email notification used by SuiteCRM (you know to send a notification when a new opportunity is won, a new lead is created etc) and all the email go directly to Promotion Tab. BUT if I change back to the regular server SMTP ([smtp.mydomain.com](http://smtp.mydomain.com)) all the email go directly to Inbox

But also the text that is included in the email and the template will have some effect too.

I use Elasticemail and they allow me to config sending mail from my own domain, eg. [mail.fususu.com](http://mail.fususu.com) but use Elastice’s IP. it goes to inbox many times. Except sometimes I have to change the title or the content of the email, Google filter some sensitive word like “money”, “sales”…

Nice to hear that, but sometimes I see it hit promotion tab, maybe the sending speed cause it. I guess Google treat some ip sending too much mail at a time like spamming.
