Generating your own list of email contacts who have opted in to receive content from you doesn't just comply with legal regulation and protect your brand reputation. It also presents you with opportunities to grow this list through genuine relationships with new customers. We've already written a post of clever ways to go about doing this, which you can check out here. But below are the basic best practices that have a very big bang for their buck when it comes to consistently growing an email list.

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.

On a more basic level, AI improves email marketing mechanics such as A/B testing and smarter audience segmentation. This can have immediate benefits in terms of optimizing your marketing strategies for different customers and sending the right content to the right people. On a more advanced note, AI can actually optimize email content for specific audiences and product campaigns. Additionally, it can help with personalizing email content right down to the individual customer level, depending on how much information you can feed it from your CRM and sales systems. AI delivers strong capabilities, which means determining exactly how a potential email marketing service has implemented AI should be key criteria for most marketers before purchasing.
Are you willing to alienate people who disagree with your opinion? Sure, not everyone who disagrees with you will unsubscribe. But if you can’t take the risk of alienating a large portion of them, it’s better to avoid the topic. The only exception are friendly disagreements. For example, it can be a good idea to show your support for a specific sport team, even if you know many in your audience like another team. As long as they don’t take the sport very seriously, it can be just a fun thing to talk about. I could, for example, tell that I’m more of a dog person (we have two dogs) than a cat person. I have nothing against cats, but I like walking with dogs. I doubt almost any cat person will hold that against me.

Use your real email signature: Just like using a real reply-to email address, you want to use real contact information within the email and the best way to do that is to include your contact details in the email signature. Giving your readers the opportunity to contact you or connect with you online is a great way to be personal and build a relationship with them.
