If you find your store heading into a downturn (or if you're already in the middle of one), you'll want to rely on your existing customers more than usual.
Most ecommerce stores only have 1-in-4 customers come back and make a second purchase (~27%). Improving that, even if just a little bit, can have a dramatic improvement to your profit.
Remember, anytime an existing customer reorders there is little or no-cost for their "acquisition". They've already been acquired. That means your marketing costs go a lot further and your profit will thank you.
Setting up a New Customer Welcome campaign is one of the best ways to reliably get those customers ordering again. It can be simple or complex, but err on the side of quickest-to-launch. This probably means using email with a set schedule for a few emails. Even something as simple as a single reminder email could be enough to get started.
(I recommend using the 1-to-2 Customer Purchase Latency as measured by Repeat Customer Insights. You're likely to get the most customer interest in that time period)
Get that campaign setup and start measuring how it changes customer behavior. The more repeat orders you get, the faster you can claw your way out of the downturn.
This works well outside of downturns as well.
Refine your automated marketing campaigns with better timing
When building any automated marketing campaign that sends messages over time, you need to know how long the campaign should be and how long to delay the messages. The Customer Purchase Latency metrics calculated by Repeat Customer Insights can help you figure out that timing.
