1. Pay attention to the design
Haste is no excuse. A simple test can provide very revealing data on the importance of a well-structured design and even on slight variations in the elements. We already know that users scan, rather than read, when they receive an email, so we must try to make it visually attractive or it will go straight to the trash.
2. Make it responsive
We know that more than half of the openings occur in mobile chemical manufacturers email lists environments and according to a recent study by BlueHornet, this is what happens if the email is not displayed correctly:

And if responsiveness still scares you, due to the lack of support for some email services (Gmail, Windows Phone…), design at least “mobile friendly” emails.
3. Short and visual texts
As we said, in the current context, users are overwhelmed by the amount of information they receive daily. This saturation is exacerbated by the multiplication of devices with which we interact simultaneously. Our attention is dispersed and as we said, when we open an email, we scan it, we skim it to see if it might interest us before paying attention to it. Therefore, we must attract said attention by summarizing the information and making it “enter” in a visual way.
4. Highlight your CTAs and make the process easier
Make it clear to the user what action you expect from them and make it easy for them. Don't "hide" the button at the end of the email, don't make them jump from one page to another, show them the way, take them by the hand to fill out your form, ask yourself what obstacles they may encounter and eliminate them.
5. Take advantage
of the Preheader We often forget about the text that many email services show after the subject. In many cases, you can read "If you can't view this email correctly, click here," and this happens because we forget about the potential of the preheader and don't take advantage of this first content of our email to summarize the content and even to interact with the subject and generate a higher opening rate. 6. Study user behavior The most valuable source of information for marketing teams is the user themselves. In email marketing, we have the golden opportunity to analyze in detail how the recipient acts and modify the direction of our efforts based on their reactions. However, many times, a strategy is followed out of inertia without stopping in depth at the analysis phase, which can provide decisive data to increase the ROI of marketing actions.
