A product drop sells best to people who asked to hear about it, and the four weeks before the date are when that list gets built. What’s missing is a crowd of people waiting when the product page goes live. A side brand on Shopify rarely has the budget to buy that attention on launch day, so the list has to exist before the product does, built from friends, past customers and the followers who keep asking “when?” under your posts.
The first decision is where those addresses will live: an email app installed from the Shopify App Store that pulls in customer records, puts a sign-up form on the storefront and sends on a schedule. Shopify has its own built-in email tool, and a guide to the best email marketing for shopify reviews 16 apps one by one, with that built-in tool, Shopify Messaging, covered in a separate section. Pick one at the start of the four weeks, because the form, the confirmation email and the waitlist tag all get built inside it.
Four weeks out: set up the store
Switch the store to a coming-soon page with a single sign-up form on it: an email field, one line saying what subscribers get (first access to the drop) and a button. Leave the consent checkbox unchecked. Yahoo’s best practices for bulk email senders tell brands not to pre-check that box and to send a confirmation email the subscriber has to click before joining the list. A mistyped address never receives the confirmation email, so it never joins the list, and your launch emails go only to addresses that work.
The same guidelines ask senders to keep spam complaints below 0.3% of delivered mail. A complaint usually comes from someone who doesn’t remember signing up and hits “report spam” instead of the unsubscribe link. Double opt-in helps here: every address on the waitlist confirmed the sign-up from its own inbox.
Tag everyone who joins through this form as “waitlist” in the email app. That tag lets you send the three launch emails to these people only and leave the rest of your customer file out of it. Check the order confirmation and shipping emails Shopify sends by default too, since they carry your logo and the sender address buyers will reply to in the week after launch.
Open the waitlist with three weeks to go
With three weeks to go, the list has time to grow while your followers still remember the teaser posts. Put the sign-up link in your bio, pin it under the Instagram or TikTok posts about the product and print it on a card that goes into every package you ship before launch, because a past customer opening a box is the easiest sign-up you’ll get. Show the product itself on the form: a photo of the sample, the price, the drop date and the size of the run if it’s small.
Skip the pop-up whose close button reads “No thanks, I hate saving money.” It annoys the people you’re trying to sign up.
The announce email, one week before
The first of the three launch emails goes to the waitlist tag seven days before the drop. It names the date and the hour with a time zone (10 a.m. Eastern is 7 a.m. for a subscriber in Los Angeles), shows the product photo again and spells out what the waitlist gets: an early link, a set quantity held back or free shipping on the first order. Write the other two emails the same afternoon and schedule them in the app, so launch day is free for packing orders and answering DMs.

Send the open email to the waitlist first
The open email is the shortest of the three: one photo, the price, a button to the product page and the end time of any waitlist perk in plain words. If early access was the promise, send it to the waitlist an hour before the public link goes up. Tap the button on your own phone before scheduling, since a link still pointing at the coming-soon page sends every early buyer to a locked store.
Keep the inventory count in Shopify admin open for the first hours. When a size or a shade sells out, edit the product page before the last call goes out so nobody clicks through to a sold-out variant.
The last call and the list after the drop
The last call goes out roughly 48 hours after the open email, to waitlist subscribers who haven’t bought. The email app builds that segment from Shopify order data: everyone tagged waitlist, minus anyone with an order since launch. Its subject line states the deadline as a day and a time, and the perk ends exactly then.
Shoppers have reason to doubt a store deadline: researchers who ran Princeton’s study of dark patterns on shopping websites crawled about 11,000 stores and found countdown timers on 361 of them, and on some the deal stayed valid after the timer reached zero.
Once the drop sells through, move the waitlist subscribers who didn’t buy to the regular newsletter, and keep the waitlist tag only on people who ask to hear about the next release.
