At worst, you might think I’m a bit weird for caring so much about sound quality. Or you might think I’m really weird if you knew that my loudspeakers are computer calibrated to my room. Or you might question my priorities if you knew I set up my office, so that my desk is nearly in the middle of it… mainly to be able to enjoy music better. But we’re all weird in some ways (and I’ll let you think this is the weirdest thing about me).
The success of daily deal email illustrates this. Customers gain value from a ‘daily deal' email and will come to anticipate the email in their inbox every morning. Tagging links in ‘daily deal’ emails will tell you a lot about the journeys within a given customer profile, as well as about preferences and behaviours. The ultimate sell is not important – what you are doing with ‘daily deal' (or ‘weekly tips') email content is building a relationship with your customers and learning more about how journeys within your brand work. All this information is important and can be put to use on later campaigns.
Calculators: A calculator offers customers a lot of value with minimal effort on their part and instant gratification. Even a simple price calculator (e.g., “How much does it cost to buy a house?”) can have impressive results: companies report lead conversion increases of more than 25%, plus a nice boost from social traffic. Offering a calculator as a call-to-action is a sign of your intent to solve a customer’s problem and add value, boosting your brand image for customers who aren’t ready to commit.
If you're inviting readers to download an ebook, for example, and you have a picture of the ebook included in the email, don't just hyperlink the text next to the image telling people to "download it here." Hyperlink the ebook's picture, too. People are drawn to images much more commonly than text, and you want to give your email subscribers as many options to get your ebook as you can.

Marketing emails need to be personalized to the reader and filled with interesting graphics. Few people want to read emails that are addressed "Dear Sir/Madam" -- as opposed to their first or last name -- and even fewer people want to read an email that simply gives them a wall of text. Visuals help your recipients quickly understand what the point of the email is.
Beyond that, avoid using all caps, too many exclamation marks, and hyperbolic phrases ("ACT NOW BEFORE TIME RUNS OUT!!!!"). Poorly formatted HTML in your emails can also hurt how they’re handled. Every spam filter is different, so an email might pass through one filter but get flagged by another. For more comprehensive info on how spam filters work and how to avoid them, check out this guide by MailChimp.

You can also voice opinions that repel people you don’t want to work with. For example, I’ve shared that I don’t like working with people who don’t take responsibility for their own life. If someone’s more likely to blame outside factors for their misfortunes than look for things they could do to change the situation, I won’t have a good time working with them.
Then, send promotional emails through Auto Responder to your list. Your subscribers will click just 1 same link (main rotator URL), and the rotator will display all the different links to different visitors. Then you can monitor how many links being delivered inside the rotator and stop it when done (You can set it to stop automatically when clicks delivered).
Ask for the right information upfront: Great personalization starts way before you hit the ‘send’ button. It all starts with your sign up form. Without data such as name, company and location, you will be very limited with your personalized communication. Remember to only ask for the information you need, rather than the information you want. This is one of the ways that GDPR has impacted marketing teams.
