#
# AMOUNT:
# - arbitrary
#
# FIK:
# - 3rd number must probably start with a 4
# - must be unique per VATID
#
# DATE

#
# EMAIL
# - arbitrary, but unique per (VATID & DATE) 
#
# TIME

#
# VATID
# - must be unique per (EMAIL & DATE)
# - must be valid (probably even existing) otherwise only first player mail is sent (with status "BASIC_PLAYER_CREATED")
