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.

Anthropologists, sociologists and historians have used mailing lists as fieldwork.[6] Topics include TV series fandom,[7] online culture,[8] or scientific practices[9] among many other academic studies. From the historian's point of view, the issue of the preservation of mailing lists heritage (and Internet fora heritage in general) is essential. Not only the text of the corpus of messages has yet to be perennially archived, but also their related metadata, timestamps, headers that define topics, etc. Mailing lists archives are a unique opportunity for historians to explore interactions, debates, even tensions that reveal a lot about communities.[10]
Have you ever heard of email campaign feedback? Email feedback plays an important role in customer-centricity. By collecting this feedback within your email campaigns, you provide a platform for two-way communication with your customers where they can share their thoughts and perceptions of your email(s) and the information you’ve provided. In other words, you as an email marketer gain insight into what your readers truly value.

Dynamic segmentation – As alluded to earlier, you can’t just send out a generic message to everyone on your list. While basic demographic data can be used to segment your list, that’s far from taking the dynamic approach. Automation tools can help you segment your list as they go through the funnel, allowing you to send personalized messaging depending on their actions and behaviors.
