bulk email using send grid in rails


You are grabbing an array of ActiveRecord objects with

@subscribers =
Subscriber.where(activated: true)

headers['X-SMTPAPI'] = { :to =>
subscribers.map(&:email) }.to_json

Solution 1: What I was trying to ascertain

Can an email header have different character encoding than the body of the email?
Email headers should use the ASCII charset, if you want the header fields to have a different encoding you need to use the encoded word syntax: http://en.wikipedia.org/wiki/MIME#Encoded-Word The email body can be directly encoded in different encoding only if mail servers that transfer it have 8bit mime enabled (nowadays every mail server should have it enabled, but it's not guaranteed), otherwis

Google Email Group not receiving specific email
This could be an issue of the mail being marked as spam by the Group, not the users. Essentially, when you leave spam on for a group, it'll get checked there and also at the user level. More informaiton about this can be found here. If that doesn't seem to be the root cause, I would check at the Email log search within the Admin console to see what's going on with a bit more detail.
