The agents ## Seven agents for Klaviyo Three work on what somebody already bought: Replenishment Reminder, Recommended Addons and Alternative Picks. Four work on what a price drop makes newly worth saying: Price Drop for a viewed product, an alternative product, a complementary product, and a purchased replenishment. The season ## One setup, three phases In October and November the agents build the audience your discounts can reach, and you pick the discounts. During the week they turn every qualifying price drop into individual emails, and you run your campaigns as planned. In December and January they work every order the week placed, and you do nothing. Pick a phase. ## One discount, four audiences The four are the shopper who viewed this exact cream, the shopper who viewed a similar cream, the customer who bought it before, and the customer who owns the cleanser it pairs with. A rule finds only the first. Flip the switch. One price drop Face cream, now 30% off Who hears about it A rule reaches one of the four. The other three wanted to know too. ## One agent email per person per day However many agents qualify for the same customer on the same morning, only one, the most relevant, goes out. You can make it stricter, layer your own frequency limits on top, and pause or restart any agent with the same toggle. After Black Friday ## One order, three follow-ups An espresso machine and two bags of beans, bought in November. In December the descaler follows, January's sale reaches the beans they already repurchase, and in February the beans run low. Step through it. 65 to 80% more items in each order from the customers who came back, and a typical order worth about a quarter more. The buyer you keep is a better buyer than the one you acquired.
