AI replenishment reminders for supplements.

With the visual automation-flow builder you set up a reminder that fires before the product runs out, based on each line's typical consumption cycle — 30 days for a monthly bottle, 60 for a longer-lasting one. It doesn't depend on someone from the team remembering to send it by hand every time: the flow runs on its own, month after month, customer by customer.

The starting point is simple: map how long each product lasts under normal use and subtract a few days of margin — so the reminder arrives before it runs out, not on the very day. That margin is exactly what separates a useful reminder from one that arrives late, when the customer has already gone to buy somewhere else.

The reminder doesn't have to be generic. Connected to your catalog and the customer's order history (via Shopify or another native integration), the message can refer to the exact product they bought last time, instead of a flat "time to buy" notice. That specificity — "your magnesium from last month" — is what makes a reminder feel useful rather than just another mass campaign.

Every outbound send from heysteff respects a clear opt-in from the customer and a simple opt-out if they no longer want the reminder. For email, the template editor includes one-click unsubscribe natively. The goal of the flow is to remind at the right moment, not to nag: setting the frequency well and respecting when someone unsubscribes is what keeps the campaign healthy over time, instead of becoming a reason to block the number.

This matters doubly if you use an unofficial WhatsApp number (Baileys): a badly calibrated sending pace doesn't just annoy the customer, it can get the entire number restricted. A well-spaced replenishment flow, with a real opt-out, is exactly the kind of recurring send you need to be most careful with.

Usage and dosage questions — how to take it, what to combine it with, how often — are answered from the agent's trainable knowledge base, using your own published information. The rule that must always be in place: define with rules and keywords which inquiries always escalate to a human or a health professional — pregnancy, drug interactions, pre-existing conditions. Steff never decides that on its own; it follows exactly what you configured, and when in doubt, it refers instead of answering.

The same applies to the replenishment reminder: if a customer replies to the reminder with a usage question instead of confirming the reorder, the agent answers it right there without losing the thread of the conversation, instead of sending them off to open a separate ticket.

Steff has vision: if the customer sends a photo of a label — yours or that of another product they're comparing — to ask something specific, the agent reads it and uses it as context for the answer, just as it does with a payment receipt. It's useful when the customer already has the bottle in hand and would rather show the label than describe it.
