Hi webmasters, a client has been running mailchimp campaigns for sending offers, etc. Now just asked me help to implement changes needed by mailchimp.
It's about modifying DNS records, creating a CNAME (DKIM: Create a CNAME) and creating a TXT record. This, on the webserver where his site is hosted (and email). I understand the aspects on authentication, this serves to make emails appear as sent by the server, not mailchimp. But I have concerns on the details (not provided). So, with such changes:
1. Does mailchimp will gain somehow, access to send mails from my server?
Doesn't sound good to me at all. Easy to flag the server or IP as mass sender or spam.
2. Would it just leave a footprint?
While the mails won't be sent from the server, such footprint will mean easy target to be flagged as mass sender.
3. I should not worry, it wouldn't affect my server, email or reputation at all.
Thanks in advance.
