What is the most efficient way to send up to 1 million emails to prospective customers. What is the fastest way? Is it best to send over 1 day, 1 week or several weeks? How to avoid blacklists and span folders?
Thank you very much for your replay. Yes, I do follow the guide lines that you mapped out in your post. I am currently sending out about 15-20 thousand emails a day but have run into delivery problems when I go above that many emails in a day. I currently use an online emailing service. But, I have read that you can get around the delivery problems (bounced, blacklist, greylist, spam) if you use a SMTP mail server to deliver the emails? Whats your advice?
