A restaurant promoted their new app with table-top signs, banners, and messages on their packaging. I frequent the establishment and went to sign up…only I was unable to do so. Come to find out, it was three days before the new app was available.
The next time I was there, I tried to sign up again but still could not, so I asked for help. This resulted in three managers taking my phone for the entire length of my meal and only then learning that the cards they had been handing out with the instructions were for the old app and did not work for this iteration. (I did get a free meal for the frustration!)
Don’t let your organization fall victim to such unnecessary sloppiness. Dial the phone numbers before you publish them. Test the links for any websites you promote. And if you go all out to promote a new app, please wait until it’s actually available and then download it yourself first. Not all your customers will have the persistence to try it over and over again.
