How to Write a Welcome Email Sequence That Converts

A new subscriber is paying more attention to you right after they opt in than they ever will again. They just asked to hear from you. Most businesses spend that moment on a single “thanks for subscribing” email and then wonder why engagement fades over the following months.

This guide covers the general five-email sequence, how to adapt it for an online store (discount code, browse follow-ups, purchase exits), and which tools handle each version well.

Why the Welcome Sequence Is Worth the Effort

Omnisend’s H1 2023 data put the average conversion rate of welcome series emails at 3.7%, the second-highest of any automated message type it tracks, according to its welcome series guide. Promotional campaigns sit well below that.

The reason is timing. A welcome sequence reaches every new subscriber at the moment they are most receptive, and once it is built it keeps running without any more work from you. Few automations pay back the setup time as reliably.

The common failure is treating it as an afterthought: one email dashed off to avoid sending nothing, stuffed with social links nobody clicks.

What You Need Before You Start

Get clear on three things before you write anything.

Who signed up and why. Different sign-up sources attract different people. Someone who downloaded your pricing guide has different intent than someone who joined after reading a blog post, and a shopper who took a 10%-off popup is in a different mindset again. If you have several entry points, build separate sequences, or at minimum use conditional content within one sequence.

What you want the subscriber to do at the end. Buy a product? Book a call? Upgrade from free to paid? Every email should move toward that outcome. Without a defined goal, the sequence turns into a loose series of content drops.

What you promised. If someone signed up for a discount code, lead with the code. If they signed up for a newsletter, lead with your best content. Matching the first email to the subscriber’s expectation matters more than anything else you do in it.

The 5-Email Welcome Sequence Structure

Five emails over 10 to 14 days is a solid starting framework for most businesses. B2B and high-consideration purchases often work better with three; content-heavy newsletters may want more. Start here and tune it from your own data. (Online stores: see the ecommerce section below for a shorter, offer-led version.)

Email 1: The Immediate Welcome (within minutes of sign-up)

This is the email your subscriber is waiting for. Send it straight away, while they still remember signing up.

What to include:

• Deliver whatever you promised: the discount, the lead magnet download, the first issue of the newsletter
• One sentence confirming what they signed up for and what comes next
• A reply invite, such as “Hit reply and tell me what you are working on.” Replies tell mailbox providers your mail is wanted, and they tell you who your subscribers are

What to skip: social media links, your life story, long explanations of your product. The subscriber signed up for one thing. Give them that thing.

Subject line: be direct. “Your [lead magnet] is here” or “Welcome, here’s what comes next.” This is not the place for clever subject lines.

Email 2: The Origin Story (day 2 to 3)

This email explains why you exist and why you are worth listening to. Keep the tone personal, not polished. Skip the brand manifesto and explain briefly what drove you to start, the way you would tell it over coffee.

Keep it to 150 to 250 words. End with a bridge toward the subscriber’s problem: “You are here because [their problem]. Here is the specific thing I help with.”

This is also where you set expectations: how often you email, what kind of content they will get, and how to change their preferences. Subscribers who know what to expect are less likely to mark you as spam.

Email 3: Your Best Content or Strongest Social Proof (day 5 to 6)

Earn attention by giving value before you ask for anything. Send your most-shared piece of content, your most useful tip, or your strongest case study. Pick one specific thing, not “here is our blog.”

A case study with a clear result fits well here. It shows what is possible without the pressure of a pitch.

Email 4: The Invitation (day 8 to 9)

This is your soft pitch: an invitation to take the next step, framed around the subscriber’s outcome rather than your product’s features.

“I help [type of person] achieve [result]. If that is where you are right now, [specific next step: book a call, start a free trial, view the pricing page].”

It should read like a recommendation from someone who knows the subscriber’s situation. Keep it to three short paragraphs at most.

Email 5: The Follow-Up or Last Chance (day 12 to 14)

Email 5 is for the people who have not acted yet. It takes one of two forms:

Service businesses and SaaS: “I noticed you have not [booked a call / started your trial / upgraded], is something getting in the way?” This opens a conversation and surfaces objections you can address.

Offers with a deadline: a reminder that the welcome offer from Email 4 is about to expire. Scarcity only works if it is real, so never invent a deadline.

After Email 5, the subscriber moves into your regular sending cadence. They know what you are about and have had chances to act. From here, treat them like any other subscriber.

Timing and Cadence

Spacing emails too far apart is the most common timing mistake. Someone who got your first email three weeks ago has mostly forgotten you. Emailing every day for a week can feel aggressive for high-consideration products.

This schedule works for most businesses:

• Email 1: immediately
• Email 2: day 2 or 3
• Email 3: day 5 or 6
• Email 4: day 8 or 9
• Email 5: day 12 to 14

For B2B or high-ticket offers, push Emails 4 and 5 out by a few days. For impulse-buy products, compress the sequence so Email 5 lands by day 7.

Send-time preferences vary a lot by audience. Once the sequence has run for a couple of months, test one change at a time (for example, moving the delayed emails from early morning to mid-morning) and compare open and click rates.

Welcome Sequences for Online Stores

A store’s welcome flow follows the same principles, but the subscriber usually arrived through an offer: a popup promising 10% off or free shipping. That changes the order. The offer comes first, the story second, and the sequence is shorter because the discount has a deadline.

The discount-code welcome: three emails

Three emails over about a week is enough for most stores. Higher-priced catalogues can add a fourth with buying guidance or reviews.

Email 1: the code (immediately). Put the discount code at the top, in plain text, large and easy to copy, using the same wording as the popup (“10% off your first order”). Anything else feels like bait-and-switch. Add a “Shop now” link and one concrete line about the brand, such as “We make organic cotton basics in Portugal.” Save the founder story for later; this email is about getting the shopper to checkout.

Email 2: story and proof (day 2 or 3). If they have not bought, they need a reason to trust you. Use a short founder note (under 150 words), two or three real customer reviews or photos, and a small “bestsellers” block of three to six products, led by images. Mention that the code is still active, but do not make it the headline. If every email leads with a discount, you train subscribers to expect one.

Email 3: the deadline (the day before the code expires). Name the deadline in the subject line: “Your 10% off expires tomorrow” is specific and true, unlike “Don’t miss out.” Show products again, ideally the ones the shopper viewed. After this email, the welcome offer is over. Any later discount should be presented as a new offer, not a quiet extension.

How long should the code last? A 30-day expiry tells the shopper there is no hurry. Seven days lines up with a one-week sequence and gives Email 3 a real deadline. Whatever you choose, keep it real.

Browse-to-first-purchase follow-ups

Many new subscribers browse but do not buy. If your store integration tracks product views, a browse abandonment flow can follow up with the exact products they looked at. In Klaviyo, browse abandonment flows trigger on the Viewed Product metric, which Klaviyo’s Shopify app embed tracks automatically. Omnisend ships a pre-built product abandonment workflow.

Decide how this flow and the welcome flow interact. A new subscriber who browses on day 2 should not get a welcome email and a browse email on the same afternoon. Either suppress browse abandonment for people still in the welcome flow, or let the welcome flow’s later emails pull in viewed products instead.

Exit the flow when they buy

Every store welcome flow needs a purchase exit. If the shopper orders during the sequence, stop the welcome emails and route them into a post-purchase flow (order confirmation, shipping update, then a “here’s what to expect” follow-up). Otherwise they get “still thinking about it?” two days after their order shipped.

In Klaviyo this is a flow filter on Placed Order; Klaviyo re-checks profile filters before each message, so someone who buys mid-flow drops out. Omnisend’s automation builder supports split paths and conditions for the same job.

Split by sign-up source

A popup subscriber and a checkout opt-in are in different places. Someone who ticked the box at checkout has already bought, so skip the discount and the “who we are” email and send them into post-purchase content. The same goes for an existing customer who signs up again with a new address: most store-connected platforms can suppress the welcome flow for anyone with a past order.

Copy that works for store welcome emails

• Open with the action they just took. “Your 10% code is below, here’s how to use it” beats “Welcome to the family!”
• Write the subject line like a text message. “Your code: WELCOME10” says what is inside.
• One call to action per email. One clear “Shop now” button, not five small links.
• Only use first names you actually have. If half your popup signups skip the name field, half your list sees “Hey there.” Skip the merge tag if you cannot capture names reliably.

Which Email Tools Make Welcome Sequences Easy

Most email platforms can run an automated welcome sequence. They differ in how much branching logic you get, how deep the store integration goes, and what the free plans include. Prices below are monthly-billing list prices at the lowest tier unless noted.

MailerLite

MailerLite is the easiest starting point. Its automation builder is a visual flow of email, delay and condition blocks. The free plan (up to 250 subscribers and 2,500 emails a month) includes 3 automations, so you can build and run a full welcome sequence without paying. Paid plans start with Comfort at $12/month for 500 subscribers.

The trade-off: MailerLite’s conditional logic is simpler than ActiveCampaign’s. If your sequence needs to branch heavily on behaviour (opened Email 2 or not, clicked this link or that one), you will hit its limits sooner.

Kit

Kit (formerly ConvertKit) suits creators and newsletter writers, and its sequence builder is straightforward. Kit’s free Newsletter plan (up to 10,000 subscribers) no longer includes visual automations or email sequences, so a welcome sequence on Kit needs the Creator plan at $39/month for 1,000 subscribers.

ActiveCampaign

ActiveCampaign is the strongest option for complex branching. Sequences can adapt to opens, link-specific clicks, site visits and purchase history, which suits a welcome flow that feeds a lead-nurturing or ecommerce funnel. Every plan includes ecommerce integrations such as Shopify and WooCommerce, plus conditional content.

Two catches. The Starter plan caps each automation at 5 actions, and a five-email sequence with waits between emails needs more than that, so plan on Plus. Plus starts at $49/month billed annually for 1,000 contacts, and there is no free plan, only a 14-day trial. For a simple five-email sequence, you are paying for depth you will not use.

Klaviyo

For stores on Shopify, WooCommerce and similar platforms, Klaviyo is the platform to beat. Every account gets a standard welcome series flow, and once your store is connected the flows can use purchase and browse data for product recommendations, browse follow-ups and purchase exits. The free plan covers 250 active profiles and 500 email sends a month, enough to build and test a flow. The Email plan starts at $20/month for 251 to 500 active profiles.

The catch is how it bills. Klaviyo charges for active profiles, meaning every contact eligible to receive marketing, not only the ones you emailed that month. Stores that collect lots of dormant popup signups pay for them. For non-ecommerce businesses, the store-first feature set adds cost without much benefit.

Omnisend

Omnisend is built for ecommerce and covers most of the same welcome-flow ground as Klaviyo for less money. Pre-built welcome series, cart abandonment and product abandonment workflows are available on every plan, including the free tier (250 contacts, 500 emails a month). Standard costs $16/month for 500 contacts and 6,000 emails.

Omnisend lets you mix email, SMS and push in one automation, so a “your code expires tonight” text can go out alongside Email 3. Check the plan first, though: Omnisend sells SMS credits as an add-on to the Pro plan ($59/month), and customers who joined Standard after May 4, 2026 cannot buy them. Reporting and segmentation are less deep than Klaviyo’s. Pick Omnisend for a solid store welcome flow on a budget; pick Klaviyo if you expect to lean on behavioural segmentation later.

Mailchimp

Mailchimp is the tool many small stores already have, but its free plan (250 contacts, 500 sends a month) does not include automation flows at all. Essentials ($13/month for 500 contacts) allows flows of up to 4 steps, which fits a three-email welcome but not five emails with delays between them. For anything longer, or for purchase exits and browse follow-ups, you need Standard ($20/month for 500 contacts). At that point Omnisend’s or Klaviyo’s store-specific flows are usually the better buy.

Common Mistakes to Avoid

Writing for the average subscriber. If someone who downloaded your advanced guide gets the same sequence as someone who entered a giveaway, both versions underperform. Segment by entry point and write for each.

Sending Email 1 late. Interest fades fast. Use a real-time trigger so Email 1 arrives within minutes. If your tool batches automations hourly, that alone is a reason to look elsewhere.

Too much, too soon. If Email 1 takes more than 90 seconds to read, it is too long. Earn attention gradually.

Hiding the discount code behind a button. If you promised a code, put it in the email body where it can be seen and copied.

No plain-text version. Many email clients show the plain-text part in previews, and a broken text version looks careless. Most tools let you edit the plain-text version next to the HTML; keep the two in sync. More in our deliverability guide.

Not testing the flow yourself. Subscribe with a test address and go through the sequence as a new subscriber. You will catch broken links, wrong delays and awkward transitions that are invisible in the automation builder.

Never updating it. A sequence written 18 months ago may mention old prices, discontinued products or stale case studies. Put a review in your calendar every six months.

Measuring Whether It Works

A good welcome sequence will not double your revenue on its own. It gives every new subscriber a deliberate introduction at the moment they are paying attention, and that tends to show up in how they engage afterwards.

Check your automation reports every month for the first three months, and look at four things:

• Open rate by email number. It should decline gently from Email 1 onwards. A sudden drop at one email points to its subject line or send time.
• Email 1 open rate against your regular campaigns. Email 1 should be the most-opened email you send. If it is not, check your confirmation step and your deliverability.
• Clicks on the Email 4 call to action (or first-purchase conversions on the welcome code for stores). If they are low, work on the offer or the copy before you touch timing.
• Replies to Email 1. Even a handful tells you what your subscribers want.

Once the basic flow works, splitting it by sign-up source is usually the next improvement. Start with one version for everyone, gather data, then split.

Where to Go Next

Pick your platform by need: MailerLite for a simple, affordable sequence, ActiveCampaign for heavy branching, and Klaviyo or Omnisend for a store. For the rest of your automation stack, see the email marketing automation guide; for stores, the abandoned cart sequence guide is the natural next flow.
