Remember, data collection is a two-way street. People won't give you their data for anything. So, think about how you are managing your subscribers' expectations. How clear is it to new recipient what they are going to be receiving from you? Try and get a good a feel for the experience of the person receiving your data collection methods as you can at this point.
There are lots of ways to buy an email list, but none of them will actually benefit your campaign. Why? Since the owners of these email addresses didn't explicitly agree to receive content from you, there's no telling how interested they are -- or if they're even a fit for what you have to offer. A bought email list is also in violation of GDPR (we'll talk more about this in just a minute).
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.

The ideal type of opinion (unrelated to your expertise) is one that doesn’t offend anyone, but makes some people relate to you more. For example, I’m a vegetarian. I used to protest whenever there wasn’t a big piece of meat on my plate. But when I tried eating just veggies for a couple of months, I realized I felt a lot more energetic. Sure, it’s more ecological. And often animals are treated cruelly. But those aren’t the things I emphasize if someone asks why I’m a vegetarian. No one in their right mind has a strong negative reaction to someone eating food that makes them feel energetic, right? But for some vegetarians it’s a very meaningful choice, so it might have a positive impact on those people. That said, I highly doubt that my choice of diet have any direct impact on my sales.
Use compelling copy – It’s important in your automated emails to create desire towards the conversion action, and there is no better way to do this than by using compelling, benefit-focused copy. We regularly use copywriting formulas such as the PAS formula or the BAB formula to achieve this in our own email campaigns, and they are two resources worth checking out. Alternatively, if those formulas don’t quite fit the message of your email then use these 5 persuasion techniques to help you write email copy that converts.

That isn’t to say that sales-y promotions couldn’t ever create results—as marketing “gurus” have proved. The results just aren’t as good as they could be. Take the biggest gurus’ results—the ones they boast about—and calculate their conversion rates. Often their marketing is comparatively ineffective. They just have massive volume, so the sales numbers are impressive.
