Five years ago, when I was a full-time consultant with a marketing company that produced advertising campaigns for clubs, I stumbled onto a unique marketing idea — send out birthday cards to non-members of the community and “gift” them a trial membership to the club in honor of their special day. The idea was born out of statistical information a client shared with me after spending a considerable amount of money having a specialist analyze their club membership data.
In an effort to identify the forces that were influencing new enrollments, this data specialist stumbled upon the finding that a significant percentage of their members had enrolled during the month of their birthday. Interestingly enough, as it related to the time of year an individual enrolled, one's birthday was the third most common statistical factor identified after New Year's and back to school.
Initially, this information surprised me, but when we discussed the reasoning, it made sense. For adults, and especially those approaching or past the age of 40, one's birthday can be a significant event that results in a time to reflect upon all areas of their life — personally, professionally, spiritually and physically. And, after New Year's, one's birthday is probably the most popular time to set new goals.
THE FIRST EFFORT
Always eager to try something new, I designed a one-color birthday card that had a verse about what influences the process of aging, along with a salutation that wished them a happy and healthy birthday. On a separate card stock insert we included a one-week trial membership gift card.
Once the card was printed a mailing list was purchased. The criteria used was adults 25 to 65 years of age, with a household income of 50,000 or more and within a certain set of zip codes that reflected the areas where the majority of club members were from. With that criteria, the list company gave us the names of individuals whose birthday it was by month for a six-month period. (Six months had to be purchased to reach a certain minimum number of names. This particular club averaged about 500 names a month.)
For that first month, the average per-piece cost to send out this first-generation birthday card was around 75 cents, for a total investment of $450. The cards got a 1 percent response rate and the club closed three out of the five prospects on annual memberships, worth around $800 each. This meant the customer acquisition cost* (CAC) for this promotion was $150, $100 less than its normal $250 CAC; certainly nothing to do back-flips over but worth the effort.
SECOND EFFORT IMPROVED RESULTS
Personally, I was disappointed with the 1 percent response rate because I believed that if the data about people having a higher propensity to enroll around their birthday was true, that the piece should have enjoyed a better than average response. So, as is the case with most direct mail campaigns, we set out to find ways to make it better and re-test the piece.
One thing about the first mailing that bothered me was that the piece was a one-color job. The reason for this was cost; because we were in the testing phase, we were printing small quantities of the cards, which meant doing 500 pieces of a two-color job would have driven the per-unit cost more than a $1. Because the piece had proven once to be cost-effective, we felt more confident in printing more pieces for the second run and, as a result, upgraded the card to two-color on a glossy card-stock paper. The insert remained one-color card stock but we decided to do a split-run on the offer, having half the cards remain a one-week trial membership with the other half changing to a full month trial. The reason for such a split was because in marketing you must be able to measure each and every change made to any piece. If we had changed the quality of the card and the offer, we would never be certain which one was having the influence. By doing the split run, we could make an accurate comparison.
Because we had printed enough cards for the remainder of the mailing list, the per-unit cost of this second generation of birthday cards remained 75 cents, which was our goal. This time, however, the response rate improved. The cards with the same one-week trial membership jumped to 2 percent and the one-month trial jumped to a 3 percent response, making the average response rate 2.5 percent, which is excellent for direct mail. The higher response rate on the one-month offer convinced us that a longer trial was more enticing. After the final calculations for the second mailing had been made, the new changes and the better response rate drove the customer acquisition cost down to less than $100 (closing percentage wasn't as high, which is normal with a higher response rate).
After six months of the birthday card promotion we knew we had a winner. The question then became how could we make it better? I evaluated the data from all the prospects who had responded and one thing struck me; where I thought the response rate would be highest among Baby Boomers and older, it wasn't. Rather, many were in the 30- to 35-year-old range.
In an effort to get some perspective, I did something that would forever change my strategy with all marketing materials. I sent a copy of the card and the inserted trial membership coupon to my mother. Not only was she the age group I expected to attract, but she was also the director of nurses at a hospital and had access to getting opinions from her employees who represented the prospects we were trying to attract. My instructions to her were clear and vague at the same time. “Mom, I'm sending you something that I would send a potential prospect of the club. I want you to look at it and tell me if you would respond to it. If the answer is no, ‘why not and what would have to change to make you respond?’ Show it to as many people at work as you can with the same goal and don't tell them your kid sent it to you. I don't want ‘that's nice’ responses, I want insights.”
When I called her back I was at first disappointed because she told me that the eight people she had showed it to said “No, they wouldn't respond.” When I asked her “Why not and what would have to change to make you respond?” my disappointment quickly turned to jubilation. This is what she told me: “It was a very nice card and a nice gift but most of us said we wouldn't use it because we didn't feel comfortable about working out. Is there any way that you could make it for us and a friend so we wouldn't have to go alone and that would be much more fun anyway?”
Have you ever had one of those moments in life when “Ding, ding, ding, ding,” the lights in your head go off? What my mother was saying made sense and yet none of us involved in creating the piece even thought that — probably because we were all fitness people.
As a result of that one insight, we changed the offer to read, “You and the friend of your choice will receive a one-month trial membership.” With the next mailing we saw a significant increase in responses — especially among older women — and by the end of another six months of mailings our average response rate climbed to 4.5 percent and further drove down the customer acquisition cost to below $60.
ANOTHER TWIST, STILL GREATER RESPONSE
For the past two years we have been using the birthday card promotion at our Rhode Island HEALTHY INSPIRATIONS locations and continue to enjoy a response rate of 4 percent to 5 percent, depending upon the month. Recently, however, following a month that had a lower response rate, one of the managers decided to put an additional gift inside the card to see if it would improve its success. The gift was a free Synergie facial, worth $40 to the consumer (our cost is around $7). Sure enough, the response rate jumped another percentage point, with the average response in any given month staying around 5.5 percent.
Since then we have offered gifts like our Shiatsu massage chair and aromatherapy treatments but the free facial seems to be the gift that elicits the increased response rate. Although this promotion doesn't pull in a huge volume of people (simply because we only have an average of 250 names per month since it is an all-women's facility), the economics are incredible.
- Because of the volume of printed cards we have the cost down to 68 cents each out the door.
- The center is spending around $250 per month (cost of mailing plus cost of gifts) but selling anywhere from $6,000 to $8,000 worth of memberships.
- The customer acquisition cost is averaging $38, which is less than half the normal cost.
With those numbers you must be thinking, “There has to be a downside.” There is; the limitation on the number of pieces you can mail out. Since you are buying a list of birthdays within a specified age, income and geographic area, you will only have a certain number of names each month. Of course, the larger the population, the more names you have to pull from. Certainly, you could expand the age bracket, lower the income level and increase the radius of mailing, but that may increase the cost without significantly increasing the number of leads. By lowering the age bracket and income levels there is a good chance that you will attract a less qualified lead, driving down the closing ratio, which will frustrate the sales staff. I don't think there is a downside to this promotion, but rather a few minor inconveniences, which include:
- Hand addressing the envelopes to keep the response level at its highest.
- Coordinating the cards to go out between the 10th and the 15th of each month. (If you have large numbers it may be economically possible to have a mailing house do this for you, but they will use labels or laser printing, which will typically lower the response rate.)
- Receiving calls from angry card recipients who want to know “How did you know it was my birthday this month? Take me off your list immediately.” (You must train your staff to handle these nicely.)
- Receiving calls from widows upset that you sent their deceased husband a birthday card. (Often widows don't take their deceased husbands off the phone directory because they don't want people to know they live alone.
There are many marketing insights from the birthday card promotion but two stick out in my mind. First, when putting together any marketing promotion, give it what I now call “The Mom Test.” That is, get uncensored feedback from the audience you are trying to reach. Listen to their concerns and suggestions and make adjustments accordingly.
Second, be patient with marketing ideas — especially if they are new and unique. If after getting just a 1 percent response with the first birthday card we dismissed the concept, a successful promotion would have been lost. Make measurable, well thought-out changes and track the response rate to ensure you are moving in a positive direction.
With some creativity, patience and consistency, you can find fun and interesting ways to bring new prospects through your club's doors and help drive membership sales.
