Recently, I was asked, “what’s an acceptable churn rate for X”, where X can be your email list, your social media following, your customer base, etc. The simple answer is straightforward: anything over zero is preferable to anything negative. At the most basic understanding of churn, you always want to be growing rather than contracting.

That said, the more complex answer is that it’s dependent on the seasonality or cyclicality of your business. For example, once upon a time, I used to market student loans. Obviously, there’s a relatively narrow demographic of people who need student loans. Thus, every June, we’d see a significant portion (20-25%) of our email list unsubscribe – they were done with college and no longer wanted or needed information about student loans. Our mailing list no longer served them (in their eyes).

Conversely, every summer around July or August, we’d see a massive influx of new subscribers as students entering college got their first tuition bills, wondered how they’d pay that obscene amount, and subscribe to every student loan resource they could find.

This massive churn rate came out as a wash, but it raised two important business questions – was there a way to keep any amount of the people we normally lost, and was there a way to capture more of the new customers. The answer to more new customers is of course media, marketing, and sales. The answer to keeping some of the losses was to diversify our product line so that we offered services relevant to people even after they left college.

Here’s a better question for you to think about. Look at your churn rate for any two properties and see how they compare. For example, does the number of returning visitors to your website look at all, percentage-wise, similar to the number of people who actively open your email newsletter? If the answer is yes, then there’s something you’re doing right to keep people coming back. If the answer is no, they look dissimilar, then one is serving your audience better than the other. Figure out what the difference is and try to strengthen the weak method.

You can use your existing media mix to help with this. Make sure that you’re cross-promoting effectively. For example, if you’ve got a robust, growing email list and other channels that are important to you are not growing, make sure to give them some added prominence in your email marketing. If you’ve got a strong Twitter account, but your email list isn’t growing, then tweet more about your list. Leverage the full power of your marketing mix!

Last night before bed, because I am a nerd, I was reading the Code of Hammurabi. If you’re unfamiliar with it, the Babylonian king Hammurabi wrote a series of laws onto giant blocks of stone. These blocks of stone were placed in public venues so that everyone could see the laws and no one could claim ignorance of the law.

Codes and laws work well because they are heuristics; instead of having to reason out and judge every problem individually, they offer mental shortcuts as to what to do in a particular situation. Here are a few examples from Hammurabi’s code:

Law 6: If any one steal the property of a temple or of the court, he shall be put to death, and also the one who receives the stolen thing from him shall be put to death.

Law 112: If any one be on a journey and entrust silver, gold, precious stones, or any movable property to another, and wish to recover it from him; if the latter do not bring all of the property to the appointed place, but appropriate it to his own use, then shall this man, who did not bring the property to hand it over, be convicted, and he shall pay fivefold for all that had been entrusted to him.

The problem with codes and laws in general is that the more laws you have, the less freedom you have to make your own decisions. An overabundance of rules, guides, codes, laws, etc. Boxes you in and blocks your creativity to solve problems. This is a doubly true in marketing.

Think about all of the marketing “rules” you have read about. People have published rules about how long a press release should be, how long the blog post should be, the optimum number of words in the title, the optimal number of words in a tweet, the best time to tweet, the best time to post on Facebook, the best time to send an e-mail, how long an e-mail should be… the list is nearly endless. If you obey all of these rules, you reduce marketing to nothing more than the manual labor. If you obey all these rules, you deny yourself any level of flexibility to deal with unexpected changes. If it’s not in the rules, then it doesn’t get done, or worse, if it’s not in the rules, you’re paralyzed into inaction and the opportunity goes away or the crisis overtakes you.

Some level of rules, laws, and guidelines is appropriate. Hammurabi had the minimum number of laws carved into large blocks of stone. When you’re manually chiseling the law into diorite (a stone harder than granite), you only put in writing what is most necessary, and in the most concise way possible. Likewise, when you’re setting up guides, rules, and policy for your marketing program, consider what the bare minimum is you’d want to set down.

If you wanted to go to an extreme, buy a Dremel and a slab of granite from your local home improvement store and consider what you’d be willing to literally carve into stone out of your existing marketing manual or strategy guide. Every time you read about a new set of marketing rules on your marketing news site of choice, ask yourself if you believe in what’s being said enough that you’d willingly carve it into stone.

You’ll figure out what is absolutely essential and what is not very quickly.

Faced with a gallery of marketing methods, tools, and tactics, figuring out which ones work best can sometimes be difficult. Here’s the one simple test I use to evaluate any marketing method:

Would I put my personal money on the line?

It’s something of a cliche, in a sense – after all, companies often state in their human resources policies on employee expenses to “treat the company’s money like your own money” but let’s be brutally honest: I’ve never met a single human being outside of the accounting department that did that.

However, the mess of marketing tools and methods becomes instantly clear the moment you pull out your personal credit card. Which methods do you truly have faith in? Which methods do you know to be so sound, so proven, that you’ll put your own dollars on the line? If you don’t have a stable of proven tools, which vendor has convinced you so thoroughly that you’d put your own money on the table?

When I started promoting Marketing Red Belt, I looked at all of the tools available on a paid basis, and what I ended up going with was email (via WhatCounts Publicaster, still the finest pure email marketing platform ever) and paid social media marketing via Custom Audiences on Facebook. Custom Audiences are such a rock-solid, sound idea that it seemed ludicrous to put my personal dollars anywhere else, and the payoff has been huge.

What’s even more glaring is what didn’t make the cut: everything else. With a very limited budget, I went with the surest bets I could count on to deliver results.

When it comes to marketing methods, what are your sure bets that you’d put your own money on? Make them the bedrock of all of your marketing campaigns.
