Replenishment flow teardown.

A replenishment flow reminds a customer to reorder just before a consumable product runs out. It triggers on Placed Order for a specific product, waits for the expected usage period, then sends a reorder email. Accurate timing and a one click route back to the same item matter more than clever copy.

Trigger and filters.

Placed Order or Ordered Product, filtered to a product or collection with a known usage life. Build one flow per product family rather than one for everything.

• Flow filter: has not ordered the same product since starting this flow
• Trigger filter: order contains a consumable item, defined by a product tag or collection
• Flow filter: not subscribed to a subscription for the same product
• Trigger filter: order was not refunded

Sequence and timing.

1. 1. Time delay set to the product life (Roughly the usage period minus a week)

   Wait until the customer is nearing the end, not the start.

2. 2. Email one: running low? (At the end of the delay)

   A helpful reminder with the exact product and a reorder button.

3. 3. Email two: reorder with ease (4 days later)

   Introduce a bundle or subscription for people who have not reordered.

4. 4. Email three: still need it? (5 days later)

   Final check, with the option to change quantity or flavour.

Branch logic.

• Conditional split on quantity bought, which lengthens or shortens the delay
• Split on whether a subscription exists on the profile, redirecting to the renewal flow
• Split on customer segment, with a loyalty note for repeat reorderers

Copy outline.

• Running low

  Name the product, estimate when it ends, and put a single reorder button above the fold.

• Reorder with ease

  Explain the subscription or bundle in two lines, with the saving described in words, not figures.

• Still need it

  Simple prompt with an option to swap size, flavour or scent.

What to watch.

• Reorder rate by product, which reveals whether your delay is right
• Time between original and repeat order, compared with your assumption
• Click to order conversion on the reorder button
• Subscription take up from email two

Common mistakes.

• One delay for every product regardless of usage
• Sending to people who have already reordered by another route
• Linking to the homepage instead of the product
• Forgetting to adjust when pack sizes change

This is a starting structure, not a promise of results. Timing and offers depend on your product, your repurchase window and your list, so test and adjust.
