Anyone asserting that mailchimp is not 'spam' is lying through their teeth..
It's why I don't blacklist MC; in my experience they are trustworthy, and bulk mail does have limited, legitimate use.
I use MailChimp to keep in touch with customers. They love it.
I ignored the rest of it.
Resent: feel bitterness or indignation at (a circumstance, action, or person): she resented the fact that I had children.
I think the second one fits better, you resent that the parent poster called MailChimp "spam"
