Mailchimp with Rules I installed MailChimp module and i am using Rules module to send emails to subscribed users. For gmail this emails are going in spam. But when i send an email from mailchimp, it's ok, no spam. There are 3 ways i see now - 


Use rules and fetch subscribed users, then send email to them
programmaticaly(worst)  
Configure rules to send emails from mailchimp.
Find another way to send emails and not get to spam.


Can i somehow make campaigns for mailchimp and send them with rules automaticaly, or you can suggest another mail module for such task?
I'm not 100% sure how this works with your setup and Mailchimp, But i have all of my site emails sending through SendGrid using the SMTP Authentication Support module. So far none have been sent to spam. 

One thing to note about SendGrid: Their free account sends your emails through a shared IP. Sometimes they can get blacklisted from time to time. But you can eventually purchase a private ip through them to ensure even better spam protection.
