Recency for Customer Retention on Subscription Based Services

Recency is a technique used to predict future Customer behaviour, based on past Customer behaviour. It aims to capture & analyse how recently each Customer has interacted actively with a Business. If recency is measured by an appropriately selected metric, it can be a very powerful predictor of future customer behaviour. Actually, it has been proved repeatedly in practise, that recency is the strongest predictor of future customer behaviour, among the three RFM analysis factors: recency, frequency, monetary. Therefore recency analysis can yield substantial business value, if carried out successfully.

The generic technique of recency analysis, has to be adopted to the different context of every Business: unique Customer lifecycle, product type. In this article we examine the important case of subscription based (or continuity) services. Such services involve the continuous usage by a Customer, often based on a contract. Common examples are: bank accounts, credit cards, fixed & mobile telecommunication services. These services are offered in highly competitive markets, characterised by high customer switching (attrition or churn) rates, which erode the profitability of those who suffer it.

The selection of suitable measurements for recency is not obvious, in the case of continuity services. A bank account or a telephone subscription is potentially used every day, therefore ‘last time used’ cannot normally be the basis for a recency measurement. The fact that the service is used, does not reflect an active choice of the Customer to interact with the Business. Therefore one should try to identify those events which reflect ‘an active choice of the Customer to interact with the Business’. Moreover, these events should be divided into events reflecting a positive attitude of the Customer towards the business and a predisposition to strengthen the relationship with the Business (e.g. a service upgrade) and events reflecting an increasingly negative attitude of the Customer towards the business (increased Customer friction) and a predisposition to terminate the subscription.

Events signalling a positive attitude are:

o An order in general

o An additional order, building up a subscription portfolio (studies in the banking sector have shown that customers with a larger product portfolio, tend to be more loyal than those with a smaller one)

o A service upgrade (e.g. moving to a higher fixed monthly fee contract in mobile telephony)

o An order for a service enhancement, taking advantage of a service feature not used before

o Enrolment to the web channel, offered by the service

o The acceptance of a campaign offer

Events signalling a negative attitude are:

o A complaint

o A product cancellation, reducing the subscription portfolio size

o A subscription portfolio termination

These two event categories of ‘reduced’ and ‘increased’ Customer ‘friction’, should be considered separately, since they have opposite effect. They should not be used in the same metric, since they may be cancelling each other.

Moreover, the selection of the appropriate division of time into recency time periods, can affect the effectiveness of the prediction. These time periods relate to the Customer lifecycle of each product type.

Alternative recency metrics can be tested on their effectiveness, with a test campaign. The best measurement is the one that produces the best response rate prediction. In addition, this metric should yield substantial differentiation in response rates between quintiles, especially in the highest recency quintiles.

Customer Lifetime Value for Value-Based Servicing, a Realistic Analysis

In order to serve their Customers according to their value (apply value-based-servicing), Businesses try to assess the value of each Customer. One approach to assess Customer value is by estimating the Customer Lifetime Value (hereafter CLV).

A strict approach to the definition of CLV (or LTV) is the net present value of future cash inflows and outflows or profits (based on the principles of financial management), related to a specific Customer. An important factor affecting the CLV is the retention rate (or alternatively the Customer lifecycle termination probability).

Theoretically speaking, a comprehensive assessment of customer value should comprise all different aspects of a customer’s contribution to the Business’s success (e.g. referrals to other Customers, cross selling potential).

A number of different approaches of varying complexity have been proposed for the calculation of the CLV:

o Some focus on cash inflows and do not integrate the customer survival factor

o Some estimate the cash inflows only: the revenue that this Customer is expected to contribute to the Business in the future.

o Some approaches which are more complicated, attempt to estimate both cash inflows as well as cash outflows: the revenue that this Customer is expected to produce for the Business in the future, as well as the Customer acquisition, service and marketing expenses.

o Some include also elements relating to the value gained from Customer referrals as well as cross selling & up selling.

All these approaches may or may not be suitable to the context of a specific Business. Asserting that a model which does not incorporate all CLV factors is invalid or incomplete, may be of academic value, but in the real Business world things are not so simple.

It can be easily understood that the estimation of the CLV, according to the above ‘strict approach’ definition is a very difficult task. This is due to the following reasons:

o The difficulty in the estimation of the duration before Customer lifecycle termination (survival probability). The business needs to implement a so-called survival function which is time-dependent, and apply it to each Customer. Moreover a survival function has its limitations since it only gives the probability of a Customer ‘surviving’ beyond a certain point in time.

o It can be difficult to assign costs related to a specific Customer (acquisition, marketing, serving, retaining, terminating). If the Business is not applying cost accounting at the Customer level, cost assignments can only be based on averages (e.g. cost analysed per Customer segment).

o The availability and quality of information related to the factors affecting CLV. Historical information may also be needed.

Each Business should evaluate:

o The readiness of its Organization, vis-a-vis predictive modeling for CLV

o The available data sources, relating to the factors affecting the CLV

o The cost to build and maintain each of the feasible options of a CLV model, in order to compare them

o The risk of building a complex model which is not successful in estimating accurately CLV, as promised

o The analysis of the additional insight and expected gains by the more sophisticated model vis-à-vis the additional cost incurred (not an easy task)

For the above reasons (costs & risks), managers are often reluctant to approve complex CLV modeling projects.

In order to overcome the Customer survival prediction issue, the Business can calculate the retention rates achieved in the past and based on these produce an estimate for the future (alternatively, an average Customer lifecycle duration per product, can be used to simplify measurements). However, in certain markets, the calculation of the yearly retention rate is not a straight forward task: a Customer termination, cannot be clearly identified before a certain time period.

CLV or an equivalent ranking can be measured per Customer segment instead of being measured per individual Customer. This can simplify the process substantially, by applying the segment retention rate and segment average cost per Customer. However, this can only be meaningful, if the segmentation mode is sufficiently aligned to the factors affecting the CLV.

The efficient application of CLV is not an easy task. A Customer about to churn has a reduced CLV, if the CLV model takes into account a churn probability. Should a business lower the Customer service level, according to a value-based servicing approach, or try to retain this Customer? The Business should try to retain a profitable Customer.

Before implementing a value-based servicing strategy, Organizational issues should also be evaluated:

o Organizational readiness should be evaluated: business processes in place, CTP’s structured to handle the value based approach, CRM information systems supporting the value ranking, trained people adopting the value-based approach

o The value-based servicing capability, related to a sophisticated CLV valuation which entails many different service levels

o How often should the CLV or equivalent value ranking, be updated. Is this realizable by the business infrastructure: does the Business have a dedicated infrastructure to calculate analytics like the Customer value rankings, in order to feed the operational CRM without computationally loading it.

A Business with no prior experience on the use of CLV should start with a simple approach: a limited complexity Customer value model. An RFM (recency – frequency – monetary) score can be used as a proxy for the CLV. This score can be a cost-effective initial Customer value ranking. In certain cases even a recency score may be a complex start. Frequency and/or monetary scores may be more suitable as a starting point.

The use of a Customer value ranking is only a means to the efficient use of business resources (value-based management). The accurate estimation of the Customer Lifetime value may be not only very difficult but also of limited business value.

Direct Mail Services

Running an advertising campaign can take much of your time, effort, and money. And if you are using direct mail marketing or advertising as a medium, you are bound to worry about many things like logistics, addresses, and the mailing system.

Just generating a mailing list can be tedious and time-consuming. But with an agency to help you, you can sit back and count on effective and creative direct mail advertising.

Agency Services

The success of an advertising campaign rests on the quality of the mailing list that you use. You must be able to target the right set of people to avoid wasting resources. People do tend to delete mail that seems to be selling them something. But if you reach the right audience, your communication will not be in vain. The advertising agency can procure the right list for you–one that features people with profiles important to your business.

Content of the mail is also very important. It has to be creative and interesting. It must be client-centered. People are turned of by blatant advertising. They must always find something in your product or service that they can benefit from. Great copywriters can get your readers hooked on your message and convince them to buy your product or patronize your services.

Layout and the total look of the mail must be attractive enough to sustain reader interest. This is where artists come in with their expertise in using visual materials, fonts and other design gimmicks. An agency can also present new ideas on advertising your product and capturing your audience’s attention.

Mailing in bulk costs money. But an agency that is in the business for a long time would have established networks and connections with mail service providers. They can arrange for special discounts for you and can assure you of fast delivery.

With the help of an agency, you do not have to spend so much time on the logistics of your advertising campaign.
