The Complete Guide to Designing Welcome Emails (Drip Campaign): A 5-Email Scenario to Drive First Purchases

The conclusion for EC welcome emails is to design them as step-by-step deliveries, with the first email sent immediately after newsletter registration, followed by a total of 3 to 5 emails delivered gradually over 10 to 14 days. The basic flow involves a welcome message and registration bonus in the first email, the brand's background in the second, popular products and reviews in the third, addressing pre-purchase concerns in the fourth, and a reminder of the bonus deadline in the final email.

In this article, based on the configurations we actually implement on-site as CRM support specialists focusing on Shopify x Klaviyo, we will explain the overall design of welcome emails (step-by-step delivery), subject line and body examples for each email, how to create entry points to increase subscribers, Klaviyo implementation steps, and performance measurement.

What are Welcome Emails? Why They Are the Highest Priority Automated Flow for E-commerce

The Most Opened Email Among All Emails

Welcome emails are a series of greeting and introductory emails automatically sent immediately after newsletter or membership registration. The period immediately following registration is when interest in the brand is highest, and the open rate of welcome emails is often around twice that of regular newsletters, sometimes exceeding 50% (this varies by product, so consider it a guideline). What is communicated in these "most read emails" largely determines the quality of the subsequent relationship with the customer.

Building the "Learn → Trust → Buy" Ladder with Step-by-Step Delivery

Most customers immediately after registration are prospects who have not yet purchased any products. The reason for sending multiple step-by-step emails (scenario delivery that automatically sends emails in a defined order and interval) instead of just one greeting is to sequentially fill in the stages necessary for a first purchase: "learning about the brand," "trusting it," and "being confident it's right for them." Once set up, it runs fully automatically, making its cost-effectiveness among the highest for automated e-commerce emails, alongside abandoned cart emails. For abandoned cart design, refer to "Complete Guide to Creating Abandoned Cart Emails."

Overall Design: Schedule of 5 Emails and Goal of Each Email

First, an overview. This shows a standard schedule for a fully equipped 5-email setup. You can start with just emails 1-3 and add the others later.

Email Number	Delivery Timing (Approx.)	Theme	Goal
1st Email	Immediately after registration	Greeting + Registration Bonus Info	Ensuring receipt of bonus and first visit
2nd Email	2 days later	Brand Story / Philosophy	Empathy and memory retention
3rd Email	4-5 days later	Popular Products / Reviews	Encouraging consideration of "which one for me?"
4th Email	7-8 days later	Addressing Pre-Purchase Concerns (shipping, returns, how to choose)	Removing purchase barriers
5th Email	10-14 days later	Bonus Expiration Reminder	Encouraging first purchase

There are two important rules. First, people who make a purchase mid-flow should be automatically excluded from subsequent deliveries. Receiving "Don't forget your first-time coupon" immediately after buying is a classic mistake. Second, adjust the frequency so that welcome emails do not overlap with regular campaign emails. Receiving emails daily immediately after registration is the biggest reason for unsubscribes.

Content of Each Email: Subject Line Examples and Opening Examples

1st Email: Greeting and Registration Bonus (Immediate Delivery)

The golden rule is to focus on "thanking" for registration and "delivering the bonus," without unnecessary elements. The coupon code should be clearly displayed in text, not an image, and its expiration date specified.

• Subject line example: "Thank you for registering | Here's your 10% OFF coupon"
• Opening example: "Thank you very much for registering. As a small token of our appreciation, we are delighted to offer you a coupon for your first purchase."

2nd Email: Brand Story (2 Days Later)

This email is solely for communicating "why we do this brand" and "what we are particular about," without any sales pitch. Topics include the company's founding story, origin or materials, and photos of the manufacturing process—background information that cannot be fully conveyed on product pages. Gaining empathy here significantly changes the open rate of subsequent emails.

• Subject line example: "Why we are particular about [product/material]"
• Opening example: "Today, instead of introducing products, we'd like to tell you a little about our craftsmanship."

3rd Email: Popular Products and Reviews (4-5 Days Later)

Introduce 2-3 standard products specifically for first-time customers. Recommending "start with these" is more likely to lead to action than listing all products. Quoting 1-2 customer reviews provides a natural endorsement from a third party.

• Subject line example: "Our Top 3 Picks for First-Time Buyers"

4th Email: Addressing Pre-Purchase Concerns (7-8 Days Later)

Those who haven't purchased by this point likely still have some hesitation. This email provides a summary of information customers often check right before purchasing, such as shipping costs, delivery times, return/exchange policies, sizing or usage guides, and frequently asked questions. While seemingly minor, this email significantly impacts the first purchase conversion rate.

• Subject line example: "We answer frequently asked questions before your purchase"

5th Email: Bonus Expiration Reminder (10-14 Days Later)

If the coupon in the first email has an expiration date, this email quietly reminds them of that deadline. It conveys the expiration date as a fact without pressure and includes contact information for inquiries if they are still undecided.

• Subject line example: "Your coupon is expiring soon (by Month Day)"
• Opening example: "This is a reminder that the coupon we sent you upon registration will expire on Month Day."

Designing Entry Points to Increase Subscribers: Pop-ups and Bonuses

The success of welcome emails is also proportional to "how many people enter the flow." The basic entry point is a registration pop-up on the site, and the key points to consider are:

• Clearly state the bonus: Specifically indicate the benefit of registering, such as "10% OFF" or "Free Shipping." Registration rates will drop significantly if only "Sign up for our newsletter here" is offered without a bonus.
• Delay display timing: Displaying the pop-up a few seconds after page load or after scrolling, rather than immediately, creates a better user experience and improves the quality of registrations.
• Limit input fields to email address only: The more fields, the lower the completion rate.
• Clearly obtain consent for marketing emails: Consent (opt-in) from recipients is generally required for sending promotional emails. Only include addresses that have given consent in the flow.

A registration rate of a few percent for pop-ups is a good benchmark. The standard approach is to A/B test different bonus contents and display conditions.

Klaviyo and Shopify Implementation Steps

To flexibly set up step-by-step delivery, an email marketing tool integrated with Shopify is necessary. We standardize on Klaviyo due to its deep Shopify integration and flexibility in branching. The implementation steps are as follows:

1. Integrate Shopify and Klaviyo (refer to "Shopify and Klaviyo Integration Setup Guide")
2. Create a signup form (pop-up) and a target list in Klaviyo
3. Create a flow triggered by list addition, and set wait times (2 days, 2 days, 3 days...) between each email
4. Set a "exit on purchase" condition (Placed Order filter) for the entire flow
5. Conduct a test registration to confirm immediate delivery of the first email, wait times, and exit upon purchase, then publish.

Instead of using a universal coupon code, using individual codes (unique coupons) that can be generated through Klaviyo and Shopify integration helps prevent code leakage and reuse.

Performance Measurement and Improvement Order

The metrics to look at are the open rate and click-through rate for each email, as well as total revenue and first-purchase conversion rate through the entire flow. As a guideline, the first email's open rate is often around 50%, and the first-purchase conversion rate via the flow is typically in the range of a few percent to 10% (this varies greatly depending on the product and average order value). For evaluating your own figures, please refer to "Average Email Open Rate and Benchmarks."

Improvements are most efficient when addressed in the following order: (1) number of registrations (pop-up bonuses and display conditions), (2) open rate of the first email (subject line and sender name), (3) content of emails at points with significant drop-offs. Instead of overhauling the entire flow at once, fix one area at a time where the metrics are weakest.

Frequently Asked Questions

How many welcome emails should I send?

3 to 5 emails are a good guideline. Just one email is not enough for brand understanding or addressing concerns, and more than 6 emails tends to increase unsubscribes. It's practical to start with 3 emails ("bonus → story → product introduction") and then add the 4th and 5th as you see results.

Is a registration bonus (coupon) mandatory?

It's not mandatory, but if your profit margin allows, it's highly valuable as it boosts both registration rates and first-purchase rates. For products where discounts are difficult, free shipping, sample inclusion, or exclusive content can also serve as bonuses. If you're concerned about registrations just for the bonus, set an expiration date and first-time only conditions.

How far apart should the delivery intervals be?

The first email should be immediate, and subsequent emails generally have a 2-3 day interval. Intervals less than 1 day can feel pushy, while more than a week can lead to customers forgetting the brand. Only the final email should be adjusted to align with the bonus expiration date.

Should I send it to existing subscribers already on the list?

Welcome flows are generally for new subscribers only. Sending a mass greeting email to an existing list can feel unnatural. For existing customers, build engagement through regular campaigns and segmented emails. If you want to reconsider your email tool choices, "Shopify Email App Comparison" may be helpful.

I'm receiving sale emails during the step-by-step delivery. Is this a problem?

This can easily lead to excessive frequency, so we recommend countermeasures. With Klaviyo, you can use the Smart Sending feature to "automatically exclude people who have recently received an email," or exclude the segment receiving the welcome flow from campaign deliveries. Prioritizing the welcome flow during the first few days after registration is the safest approach.
