Hi guys! I have a list of about 1000+ clients from previous seo projects and their emails/names etc as they submitted their details via a order form. I was wondering, which method can I use to send out a email to those 1000+ email addresses with one message and NOT require them to confirm to be on my list. Can I send this out through gmail/hotmail etc? (but not let them see who I sent it to?) Or can anyone suggest any services, where I can import and send? Thanks in advance!
