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.
You can assess the interests of individual list members by monitoring which pages they land on, and where they go from there. The process is explained by this example from Airbnb. They use click behaviour to ascertain the destination preferences and travel styles of customers and base their follow-up emails on those preference profiles. It's intensely specific, but it gets results!
My next answer:                                                                                                                    - You see, - I could easily charge $100 or even $200 for a copy of this unique Self-Send-Solo System, - but why shoul I? My main income are made from other websites I own, not from this one here - this one here is more for fun and of course I make money from sales, (after all I am a business man)
Measure your results – Most email marketing tools will give you comprehensive data on email-related metrics like opens, clicks, etc. Some will even show you a real-time world map of people engaging with your email. However, to truly measure and optimize the results of your automated email you need to go beyond these metrics and look at the fundamental numbers that matter to your business, things like visits, customers and revenue. Google Analytics is a powerful and free tool to use to do this, and we’ve made a free Google Analytics dashboard that you can use to measure the effectiveness of your email marketing at a glance. If you’re more of an advanced user, check out our 4 favorite Google Analytics reports for measuring email marketing.
Are you willing to alienate people who disagree with your opinion? Sure, not everyone who disagrees with you will unsubscribe. But if you can’t take the risk of alienating a large portion of them, it’s better to avoid the topic. The only exception are friendly disagreements. For example, it can be a good idea to show your support for a specific sport team, even if you know many in your audience like another team. As long as they don’t take the sport very seriously, it can be just a fun thing to talk about. I could, for example, tell that I’m more of a dog person (we have two dogs) than a cat person. I have nothing against cats, but I like walking with dogs. I doubt almost any cat person will hold that against me.
The downside of just making offers is that they’re not useful on their own. People on your list won’t receive any value from you unless they buy what you’re promoting, so they have little reason to stay subscribed. That’s why this email marketing strategy doesn’t work alone. And it’s why many e-commerce sites struggle to keep people interested. There are a few exceptions (e.g., Groupon) that rely entirely on making offers—but then the reason people joined the list was specifically to receive those offers.
Messages which require online action work better in email than DM (direct message on social media), whereas calls-to-action to text to a shortcode or download a mobile app work fine within a DM. RFM and response analysis will indicate channel preference since customers with a preference for specific online channels will be more responsive in them and will make more purchases online.

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.
