Your customers, prospects, and partners are the lifeblood of of your business. You need to build your marketing strategy around them. Step 1 of marketing is understanding what your customers want, which can be challenging when you’re dealing with such a diverse audience. This chapter will walk you through (1) the process of building personal connections at scale and (2) crafting customer value propositions that funnel back to ROI for your company. https://www.agilecrm.com/blog/wp-content/uploads/2017/10/How-to-Design-a-Good-Drip-Email-Campaign-.jpg
A campaign is a marketing message that you share through email or ads. In Mailchimp, most users start with a regular email campaign, which is a bulk email sent to many contacts at once. When you create a regular email campaign in Mailchimp, you’ll use a checklist-style Campaign Builder to add recipients, choose your settings, and design your content.
If you sign up for something and the terms include words like "Sign up to receive updates from us and our partners that we think you'll like," your email address is likely being collected for a shared or sold list. A subset of this method is called co-registration. This is where you sign up at a website, but that website also automatically, or nearly automatically, signs you up for other sites. They try to legitimize this by informing you of the additional subscriptions, or providing boxes to uncheck. This is a situation where it's not the subscriber’s intention to sign up for the material they will be receiving.
This is not a recommended email marketing practice any more. The most successful email marketers segment their lists. The cutting-edge marketers are using things like dynamic content to take personalization even further. But even beginner email marketers can add a subscriber’s name to subject lines. Even that has been shown to give a nice lift when used appropriately.

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.

A/B testing is trying two different techniques that communicate the same message on a small percentage of your list, seeing whether A or B performed the best, then using the better performing option when you email the rest of the list. It sounds complicated, but there are plenty of email marketing solutions out there that take all the math and guesswork out of it. (All you have to do is come up with the option A and option B you want to try.)
Particular groups of customers can be targeted or even individuals. Offering individual customers special deals on merchandise and/or services on the customer's birthday, for instance, is one example of email marketing personalization. (A restaurant might send an email to customers on their birthday offering 50% off an entree,) Email marketing helps a business develop and maintain a relationship with a customer over time that hopefully results in increased sales and increased customer loyalty.
