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.
With the GDPR now governing all email correspondence across Europe, adding an opt-out option to your email template no longer cuts it. Under this act, you must have explicit consent from your contacts to send them emails. Explicit, in this case, means the checkbox a person must click to opt in to an email subscription isn't pre-checked when they see it on your website. And when you buy your email lists, the people on it haven't been given this option -- making you non-compliant with GDPR before you send your first email.
Non-promotional emails, on the other hand, will be less sales-driven and timely, and more focused on building relationships and providing value to your customers. While promotional email campaigns generally tend to yield a higher click-through rate, non-promotional messages allow you to see what interests your email subscribers so you can segment accordingly. You can follow up later with more targeted messages that help to nurture your relationship with these audiences.
Email marketing is the practice of sending various types of content to a list of subscribers via email. This content can serve to generate website traffic, leads, or even product signups for a business. It's important that an email campaign's recipients have personally opted in to receive this content, and that each newsletter offers something of value to them.
