Enter the topic, the basic service of marketing system “coupon service”. Introduce coupons by asking:

  • What types of coupons are available?
  • What is the scope of the coupon?
  • What are the common scenarios of coupons?

  • How to control the risk of coupon service?

What types of coupons are available?

For users who obtain coupons, they focus on the preferential ability of coupons, so coupons are mainly divided into the following three categories according to the preferential ability dimension:

Preferential capacity dimension describe
Full cut coupons How much can be deducted from the full amount (excluding postage)
Cash coupon How much cash to deduct (no threshold)
rebate To deduct the entire amount of a Sku (one quantity)
Discount coupons At a discount

For operators who issue coupons:

One is the “fixed expiration date,” where the coupon’s expiration date and expiration date stamps are determined at the time the coupon is created. The user can get the coupon at any time, and the validity time of the coupon is the start and end time of the validity time previously set.

The other is the “dynamic validity period”, creating coupons to set the validity period, such as 7 days, 12 hours, etc. For this kind of coupon, the time when the user collects the coupon is the start time of the validity period of the coupon, and the time when the user collects the coupon + the validity period is the end time of the validity period.

Dimension of validity Type of coupon Effective time of coupon Coupon expiration time describe
fixed Fixed term The coupon type was determined when it was created The coupon type was determined when it was created No matter when the user receives the coupon, the effective time of the coupon is the set uniform time
dynamic Dynamic validity period The current timestamp when the user receives the coupon The current timestamp is + N*24*60*60 when the user receives the coupon When a coupon type is created, only the validity of the coupon is determined, for example, 6 hours, 7 days, or a month
