Email campaigns that stand out and bring about a sense of emotion are great to get subscribers sharing with others. Creating calls to actions and valuable content within your email that is timely and closely related to what your subscribers care about will help the virality of your email campaign. In a world where 20% of subscribers open email newsletters it is important to segment your audience to deliver the best content possible and also create clear calls to action so subscribers don’t need to think about what they need to do with your message.
There’s a second downside to this model. Although I’ve done advertising and sponsorships in the past, and have made hundreds of thousands of dollars doing so, the truth is it takes a lot of time for this business model to start to generate income for you, because you need to build that audience first. In addition, what happens when you build your audience on a platform that ends up changing its algorithm, affecting how often you actually get seen by the audience you’ve built?
What I did:The first two years of work in NYC was brutal. I told myself there was no way I could work on Wall St for my entire career because I’d probably die from heart failure by age 40. Having an early death in my mind willed me to save 50%+ from the first year onward and devise a CD, real estate, and stock investment distribution system for my savings every year. I thought about starting this site for at least a year before I hired someone from Craigslist to give set me up and push me forward. Hiring someone to get started is totally worth it if you are a master procrastinator. You can now learn how to start your own site with my step-by-step guide to save yourself time and money. 
This one may seem simple, but that’s only because it is. If you were to move your savings from a traditional, brick-and-mortar bank with a low-interest rate and into a high-yield savings account online, over time you can make a surprising amount of extra cash. Online banks are FDIC-insured just like the traditional brick-and-mortar institutions, so your money is just as safe.
There are now two ways to sell on Etsy–physical and digital products. With physical products, you can either create something unique such as jewelry or buy and resell something–for example, vintage clothing. Etsy has been a great marketplace for a long time, helping creative people sell their goods. The problem is, selling physical products isn’t exactly passive income.
Investing your money is one of the oldest passive income strategies on the books. Investing in stocks (or funds of stocks) means that you are becoming a (very) partial owner in the company whose stock you own. When you purchase a stock, your expectation is that the value of the stock will either increase or decrease, and your goal is to buy low and sell high. (This is what everyone is shouting about on the floor of the NYSE in movies about the world of high finance).

Remember the HillTop ad that Coca-Cola did? If not, perhaps the lyrics will spark a memory - "I'd Like to Buy the World a Coke."  Is the song stuck in your head?  This jingle had the whole world singing, and if that weren't enough, it was recently revisited on the Mad Man series that had everyone humming it again.  The song spoke of unity and tolerance, and as consumers, we gravitated to it and shared it.
If you’re looking for a way to begin gradually replacing your income, these are just some of the best ways you can do it as a physician. Remember the idea of gradual retirement? Passive income streams like the ones mentioned here are perfect ways to allow you to spend more time with family, enjoy your day job more, and, of course, make a little money while you’re at it.

The vast majority of my investing is in retirement accounts and won't be tapped for income until I reach at least 59.5 years old. However, I have a very small taxable investing portfolio (less than $5k) with Ally Invest where I invest in a handful of stocks that I value. I do not use the earnings as income – I simply hold these stocks. But I have an unrealized gain of $340 from this year so far.
What if there was a way for you to effectively make money while you sleep? Sounds like a dream come true, right? Even for the biggest workaholics, there are only so many hours in a day. If only you could get paid multiple times for something you did once—that’s exactly how passive income works! Thanks to technology, the potential to create multiple income streams is even easier than ever before. We’re no longer held back by the limitations of a traditional 9-to-5 job, and financial freedom is at our fingertips. Even if you already work a full-time job you can still improve your financial health with passive income.
Obviously, these are much higher than you’re going to get with most other investments. What’s more is that you can choose a plan that matches your investment strategy, whether your goal is Supplemental Income, Balanced Investing, or Long-term Growth. You can also look at different real estate projects and choose for yourself which ones to invest in.
A short study of this web site reveals that a hugely important factor for success in startup companies is finding ways to acquire customers at a low cost. In the Business Models section, we looked at the perfect business model: Viral customer acquisition with good monetization. However viral growth turns out to be an elusive goal, and only a very small number of companies actually achieve true viral growth.
What I did: I first identified my favorite places in the world to live: San Francisco, Honolulu, Paris, Amsterdam, New York City, and Lake Tahoe. I then looked up the median rent and housing prices for each city. Then I factored in private education costs for two kids to be conservative given I may not have two kids and public schools are often good enough. After calculating all vital costs, I then did a self-assessment of how happy I was making $50,000, $100,000, $150,000, $200,000, $250,000, $350,000, $500,000, and $750,000. I decided working 20 hours a week making $200,000 a year is the best income balance for maximum happiness. 
Dividend Income: Dividend income is wonderful because it is completely passive and is taxed at only 15% if you are in the 25%, 28%, 33%, and 35% income tax bracket. If you are in the 39.6% income tax bracket you will pay a 20% tax on your dividends. My dividend income portfolio mainly consist of dividend equity and bond ETFs such as DVY, VYM, MUB, TLT, and IEF. Total stock and bond income is a little over $100,000 a year due to a heavy accumulation of stocks and municipal bonds after selling my house.

Quick question. I’m 21 years old and currently working full time (50 hours a week averaging about 12 dollars an hour. I was working 35 making enough to get by and save a little, but I read your post on the notion of working more than 40 to get ahead and decided a third job was best while I’m getting residency to get lower- instate tuition at OSU. So props, you had a direct influence on my life.)
I like the way you have listed the ways to earn extra income and was quite surprise that you did not make mention of network marketing, which is a way to make extra income without quitting your regular, though most people view mlm as a pyramid scheme but the real pyramid scheme is a regular 9 to 5, because you can only have one president of a company at any given time and network marketing business model to promote product that can be used is really cheap to join and can offer a substantial extra income or what do you think?
The campaign didn’t target Dove’s products but instead focused on changing a woman’s perception of how she sees herself, also changing the way how Dove is viewed as a company. It is said that “Woman aged between 18-34 are twice as likely to think highly of a brand that made an empowering ad and nearly 80% more likely to like, share, comment, and subscribe after watching one.” Through the video, Dove wanted to make women realize that they are overly-critical of themselves to make them feel better about their appearance.

Writing an e-book is very popular among bloggers, as many have noted that “it's just a bunch of blog posts put together!” You will not only have to make an investment of time and energy to create the e-book, but market it correctly. However, if marketed correctly (through blogging affiliates in your niche, for example), you could have residual sales that last a very long time.

A quick look at the table that shows the effect of varying the Viral Cycle Time shows that customer growth is dramatically affected by a shorter cycle time. For example, after 20 days with a cycle time of two days, you will have 20,470 users, but if you halved that cycle time to one day, you would have over 20 million users! It is logical that it would be better to have more cycles occur, but it is less obvious just how much better. A quick look at the formula tells the whole story. The Viral Coefficient K is raised to the power of t/ct, so reducing ct has a far more powerful effect than increasing K.
This was a great move for Dove who had become very quiet in the marketplace in the years beforehand. They were able to realign their brand to be all encompassing and to suit young and old women alike. The emotional undertone to the campaign made is hit hard with women no matter what their social standing, religious beliefs, etc. If you plan to carry out a viral marketing campaign similar to this example be careful not to inadvertently distance yourself from certain social groups by appearing too up market or shabby.
Message: Only messages that are both memorable and sufficiently interesting to be passed on to others have the potential to spur a viral marketing phenomenon. Making a message more memorable and interesting or simply more infectious, is often not a matter of major changes but minor adjustments. It should be unique and engaging with a main idea that motivates the recipient to share it widely with friends – a "must-see" element.[22]
