Paperless billing and bill pay has been gaining in practice for years now, but one of PerfTech’s large telco-operator customers decided that 2020 was the year to finally go completely online for bill pay.  Approximately 7% of their broadband subscriber roster still needed to be registered. 
Using PerfTech’s in-browser messaging platform, the telco began a campaign designed to sign up customers during 5 separate time-windows spaced over a span of seven months.  Each message announced the move to online-only bill pay and asked the subscriber to take one of the following positive actions:  register, indicate that they had already registered, or learn more.  Action buttons also included close or remind me later; these counts are not included below as both resulted in redelivering the message later.  Positive action results are below:
Time-Window                February                March                June                July                August 
Days in Window              12                             11                       7                      3                      3
Response Rate               27.4%                      22.5%                17.4%                12.7%               12.4%
The total number of subscribers targeted to receive the in-browser message was determined at the beginning of the 5-window campaign; as subscribers registered, they were removed from the list.  As the campaign progressed , delivery time-windows became smaller, as did the number of subscribers left on the list and the number who responded immediately.  During each of the first two time-windows, approximately a quarter of the targeted subscribers took immediate action; during the last three time-windows, approximately another 42% responded, for a sum total of 92.4%.  Additionally, subscribers could go online and register at any time, not just immediately upon receiving a message.  The end result of the campaign was to bring the number of unregistered-online subscribers to a minimum, a goal the telco believed it achieved.
