Most stores add a wishlist button, watch shoppers heart a few products, and then do nothing with that information. That’s a waste. Every saved item is a shopper telling you, in plain terms, “I want this, just not right now.” Few signals in your store are clearer than that.

This post covers how to treat your WooCommerce wishlist as a marketing channel: the reminders worth sending, how to handle price drops and stock changes, and what the data can tell you about your catalog.

Why wishlist data is so valuable

Compare the signals a shopper gives you:

The cart is about this session. The wishlist is about later. That makes it a natural fit for follow-up marketing, because the shopper has already told you which products to follow up about. You don’t need to guess from browsing history.

If you haven’t added a wishlist yet, our WooCommerce wishlist guide covers the basics of setting one up.

Step one: make sure you can reach wishlist users

A wishlist only becomes a marketing channel if you can contact the person behind it. There are two common approaches:

• Logged-in wishlists. The shopper has an account, so the wishlist is tied to their email. This is the most reliable option.
• Guest wishlists with email capture. The wishlist is stored in the browser, and you invite the shopper to “save your wishlist” or “get notified about price drops” by entering an email.

The second approach is a strong list-building tool, because the reason to sign up is specific and useful. “Email me if this goes on sale” is a far easier yes than “Join our newsletter.”

Whatever you choose, be clear about what they’re signing up for and follow the consent rules that apply to your customers. A person who asked for price-drop alerts on one product hasn’t necessarily agreed to your weekly newsletter.

The four wishlist emails worth setting up

1. The gentle reminder

Send a reminder a few days to a couple of weeks after an item is saved, if it hasn’t been bought. Keep it light:

• Subject: “Still thinking about the linen shirt?”
• Show the product image, price and a direct link.
• Add one reason to act: a detail from the product page, a customer review or your returns policy.

Don’t send a discount by default. Many shoppers just needed a nudge, and training everyone to wait for a coupon eats into your margin.

2. The price-drop alert

When a wishlisted product goes on sale, tell the people who saved it. This is the most useful wishlist email because it answers the most common reason for waiting.

Tips:

• Show the old and new price clearly.
• Say how long the sale lasts, if there’s a real end date.
• Send it soon after the price changes, not days later.

A worked example: say 120 shoppers have one particular jacket on their wishlists and you’re planning a 20% promotion on outerwear. Those 120 people are the first audience to notify, before your general list, because they’ve already chosen that jacket.

3. Low-stock and back-in-stock alerts

If a wishlisted item is running low, a short “only a few left in your size” message is honest urgency, as long as it’s true. If an item sells out, let wishlist users know when it’s back. Many stores run a separate “notify me” feature for out-of-stock products; wishlist data gives you a second, warmer list for the same product.

4. The seasonal or occasion nudge

Wishlists often double as gift lists. Before birthdays, holidays or seasonal sales, send a roundup: “Your wishlist has 4 items. Two of them are part of this weekend’s sale.” You can also invite shoppers to share their wishlist with family, which introduces your store to new buyers.

Setting sensible rules

Wishlist emails can become annoying fast if every save triggers a new message. A few guardrails:

• Limit frequency. One wishlist email per person per week is a reasonable ceiling for most stores.
• Group items. If someone saved five products, send one email about all five rather than five emails.
• Stop when they buy. Remove purchased items from future reminders.
• Let them unsubscribe from wishlist emails without leaving your store emails altogether, if your email tool allows it.
• Expire old items. A product saved nine months ago and never revisited probably isn’t worth another reminder.

On-site uses for wishlist data

Email isn’t the only channel. Wishlist data can shape the store itself.

• Returning-visitor messages. When a known shopper comes back, a small banner or popup such as “An item on your wishlist is now on sale” can bring them straight to it.
• Cart-page reminders. Showing wishlist items near the cart reminds shoppers of things they already wanted and can increase order size.
• “Most wishlisted” collections. A collection of your most-saved products is a form of social proof and helps new visitors find popular items.

Using wishlists as a research tool

This is the part most store owners skip. Your wishlist report is a free, ongoing survey of what people want.

Spot pricing problems

If a product is wishlisted often but rarely bought, price is a likely reason. That doesn’t automatically mean you should cut it. You could:

• Test a small bundle that adds perceived value at the same price.
• Offer a payment option that spreads the cost, if your gateway supports it.
• Improve the product page so the price feels justified.

Plan stock

Heavily wishlisted items are demand you haven’t captured yet. Before reordering, check which products and variations are saved most. A size or colour that’s wishlisted a lot but frequently out of stock tells you what to order more of.

Choose what to discount

When planning a sale, the most wishlisted products are strong candidates. The demand is already there, and you can reach those shoppers directly. The reverse is also useful: products nobody saves or buys might need better photos, a new description or a clearance plan.

Test new products

Some stores add upcoming products to the catalog with a “coming soon” status and let shoppers wishlist them. The number of saves gives you a rough read on demand before you commit to a large order.

A simple wishlist marketing plan for a small store

If you’re starting from zero, here’s an order that works:

1. Week 1: Make sure wishlists are tied to an email, either via accounts or a “save your list” prompt.
2. Week 2: Set up the price-drop alert. It has the clearest value for shoppers.
3. Week 3: Add a single reminder email about a week after an item is saved.
4. Week 4: Add back-in-stock alerts for wishlisted items.
5. Monthly: Review your most wishlisted products and compare them to sales. Adjust stock, pricing or product pages based on the gaps.

Choosing the tools

You can build this with a combination of a wishlist plugin and your email platform, as long as the two can share data (usually through tags, custom fields or an integration). Check that your wishlist plugin can:

• Store wishlists for logged-in users and capture guest emails
• Trigger events when a wishlisted item’s price or stock changes
• Export or sync data to your email tool
• Show reports on the most wishlisted products

iConvert Optimizer includes wishlists as part of its conversion toolkit, so the wishlist data sits next to recommendations and cart recovery rather than in a separate plugin. Whatever you use, the principle is the same: capture the intent, then follow up on it.

Make your wishlist work harder

A wishlist button that only stores hearts is a missed opportunity. Treat each save as permission to follow up about one specific product, send the messages shoppers actually want (price drops and stock alerts first), and review the data every month to guide stock and pricing. Done well, it’s one of the most relevant, least pushy channels a small store has.

If you’d like wishlists that feed your marketing out of the box, iConvert Optimizer is worth a look.
