- the communication network (1) comprises at least one test receiver (11a), a first survey receiver (22a), a second survey receiver (22b), a final receiver (3a), a tracking server (5), a receiver database (6), a survey database (7), an evaluation module (121), a selection module (122), and a central server (8), and a relevance of a final message (30a) for the final receiver (3a) is determined before the final message (30a) is sent, having the following steps:
- generating a first test message (10a), a second test message (10b), a third test message (10c), and a fourth test message (10d) by means of the central server (8), wherein each test message (10a, 10b, 10c, 10d) comprises at least one first message feature (12a, 12b, 12c, 12d), and the first message feature (12a) of the first test message (10a) and the first message feature (12b) of the second test message (10b) are changeable by means of a change in a respective corresponding value (14a, 14b) of a first parameter, and the first message feature (12c) of the third test message (10c) and the first message feature (12d) of the fourth test message (10d) are changeable by means of a change in a respective corresponding value (14c, 14d) of a second parameter, and the respective corresponding values (14a, 14b) of the first parameter are different and the respective corresponding values (14c, 14d) of the second parameter are different;
- transmitting the first test message (10a), the second test message (10b), the third test message (10c), and the fourth test message (10d) to a first test receiver (11a), a second test receiver (11b), a third test receiver (11c), and/or a fourth test receiver (11d) by means of the transmitter (2);
- detecting a first reaction behavior with respect to the test messages (10a, 10b, 10c, 10d) by means of the tracking server (5);
- evaluating the first reaction behavior by means of the evaluation module (121);
- determining an influence value of the first parameter, which detects an influence of the first parameter on the first reaction behavior with respect to the test messages (10a, 10b, 10c, 10d), and determining an influence value of the second parameter, which detects an influence of the second parameter on the first reaction behavior with respect to the test messages (10a, 10b, 10c, 10d),
- comparing the influence value of the first parameter to the influence value of the second parameter, and determining a selection parameter (52) by means of the selection module (122), wherein the particular one of the two parameters, the first parameter and the second parameter, that has the greater influence on the first reaction behavior is determined as the selection parameter (52);
- generating at least one first survey message (21a) and a second survey message (21b) by means of the central server (8), wherein the survey messages (21a, 21b) each have at least one first selection message feature (20a, 20b), wherein the respective first selection message feature (20a, 20b) is changeable by means of a change in a respective corresponding value (23a, 23b) of the selection parameter (52), and the value (23a) of the selection parameter (52) of the first selection message feature (20a) of the first survey message (21a) is different from the value (23b) of the selection parameter (52) of the first selection message feature (20b) of the second survey message (21b);
- sending the first survey message (21a) and the second survey message (21b) to at least one first survey receiver (22a), a second survey receiver (22b), and/or a third survey receiver (22c) by means of the transmitter (2), wherein the survey receivers (22a, 22b, 22c) are distinguishable by at least one first receiver feature (51);
- detecting a second reaction behavior with respect to the survey messages (21a, 21b) by means of the tracking server (5);
- evaluating the second reaction behavior by means of the evaluation module (121);
- creating a respective survey data set (26b, 26c, 26d) for at least two survey receivers (22b, 22c), wherein the respective survey data set (26b, 26c, 26d) comprises a value (28b, 28c, 28b) of the first receiver feature (51) of the respective survey receiver (22b, 22c), an evaluation (27b, 27c, 27d) of a corresponding individual second reaction behavior of the respective survey receiver (22b, 22c), and a corresponding value (23a, 23b) of the selection parameter of the survey message (21a, 21b) received by the respective survey receiver (22b, 22c);
- storing at least two of the survey data sets (26b, 26c, 26d) in the survey database (7) on the database server (9), wherein an association of the values (28b, 28c, 28b) of the first receiver feature (51) with the values (23a, 23b) of the selection parameter (52) and with the evaluations (27b, 27c, 27d) of the individual second reaction behavior is provided by means of the survey data sets (26b, 26c, 26d) stored in the survey database (7);
- sending the final message (30a) by means of the transmitter (2), wherein a value (29a) of the first receiver feature (51) of the final receiver (3a) is read out from the receiver database (6), the final message (30a) comprises at least one first final message feature (31a), the first final message feature (31a) is changeable by means of a change in a corresponding value (32a) of the selection parameter (52), the value (32a) of the selection parameter (52) is adapted to the read-out value (29a) of the first receiver feature (51) of the final receiver (3a) by means of the association provided by the survey database and a relevance of the final message (30a) for the final receiver (3a) is determined before sending the final message (30a) in the form of an individual estimated reaction value (53) of the final receiver (3a).
