Understand the statistics. Click-through rate or CTR is how often customers click on links contained in your email. There is also a conversion rate, which tracks how many people took action after clicking your link, as well as a rate for how many people opened and read your email. Many email blast software will have these metrics built in. Do not make things in the email blast confusing or complicated as it can prevent people from taking action or even reading the blast.
This list buying is a very tricky subject and I agree that there must be something to it (demand and utility) or there would not be pages on google advertising . I am really tempted but not with a purchased list . I have 24000 emails from my customers from my website listed above that has been up about 10 years. These are people who have requested automatic rate quotes from our db. About 1/3 of them we had email correspondence with . This are years 2012/13. Now I am into internet marketing and would like to have some good advice about mailing to this list without hurting my present web traffic Thanks Walter Menuet
Purchased lists are ineffective, and they impact everyone else who uses Mailchimp, too. If you send emails to a list of people whose contact info you bought, many of the emails will get identified as spam. Some spam filters will flag a campaign if anyone with the same IP has sent spam in the past. When you use Mailchimp, your email is delivered through our servers, so if one person sends spam, it could prevent other users’ emails from reaching inboxes. But by forbidding Mailchimp users from using purchased lists, we increase deliverability for everyone.
E-marketing joins creative and technical aspects of the Internet, including: design, development, advertising and sales. It includes the use of a website in combination with online promotional techniques such as search engine marketing (SEM), social medial marketing, interactive online ads, online directories, e-mail marketing, affiliate marketing, viral marketing and so on. The digital technologies used as delivery and communication mediums within the scope of e-marketing include:
Ensure your email list is comprised of contacts whom have either opted in or whom you have a strong working relationship with. If you don’t have a list like this, focus on building one before you start sending anything out.  Quality email address are more important than the quantity of them. If you’re not sure if you have a good list, check out our blog post: Answers to Frequently Asked Email List Questions.

You don’t have to worry about Google or Facebook suddenly changing their algorithms, because once you have someone’s email you have the ability to communicate with them one on one. Even if all of Foundr’s search rankings and social media presence disappeared tomorrow, we’d still be able to promote our brand and our products to the thousands of people on our mailing list.

There are many vendors out there who sell lists or rent them (though renting means that the list seller maintains ownership and control of the email list). These are collections of email addresses that the vendors sell to any business or individual who can pay the fees. Your email list is considered to be a purchased or shared list if it’s provided to you by a third party, like an email list vendor or affiliate. There's a few ways that vendors build these non opt-in email lists.
