In 8years of starting up my business, I have kept customers emails, up to 20k of them. I also have access to over 60k emails which I acquired from several legitimate sources but not directly.
I want to setup mailchimp to manage my email. And I am wondering the best way to go about it without getting my new website flagged.
I am considering: buying: up to 20 other similar domains and creating 20 different mailchimp accounts, splitting the emails into: 4-5k each, and using each to manage the 5k list.
Or I should simply get a my own mailing server and create a server blast campaign, and manage it . we configure the server we use multiple domains to do the RDNS thats how we are able to send emails with ease. and rotation of ips.
My fear is I can't give my own server the best attention and get the best delivery in box rate.
Question is: Will mailchimp give me problems since when the emails are sent, they leave from a different domain, which is similar to my real domain, customers won't notice, and will gladly click into our real website. Will mailchimp give me any issues?
