Email Marketing Setup: The Three Flows That Matter First

New store owners tend to think email marketing means a newsletter — a weekly send you have to write forever. Good news: that is the last thing to build. A store's email program starts as three automations you set up once, and which then work every hour you are asleep. This guide covers those three flows in setup order, what each one does, and which app tier you actually need to run them — which, at the start, is a free one.

Flow 1: The welcome series

Trigger: someone joins your list (usually via a signup form or discount offer). Job: convert intent into a first order while attention is warm.

A serviceable welcome series is two to three emails over about a week: deliver whatever was promised at signup, tell the short version of why the store exists, and show the two or three products that best explain the catalog. Across published benchmarks and user-reported results, welcome emails reliably out-engage every other message a store sends — the subscriber literally just asked to hear from you. That is why this flow is first: highest attention, zero recurring writing.

Practical settings: send the first email immediately, not hours later. If you offered a discount for signup, the code goes in message one, unmissably.

Flow 2: The abandoned-cart flow

Trigger: a shopper adds items and leaves without checking out. Job: recover proven purchase intent.

This is usually the highest-ROI automation a store ever turns on, for a simple reason: the shopper already did the hard part. A typical flow is two to three messages over 24–48 hours — a plain reminder first ("you left these"), then, optionally, urgency or an incentive later. Two cautions the aggregated user wisdom agrees on: do not lead with a discount (you will train shoppers to abandon carts deliberately), and do not send message one instantly (give the shopper an hour to finish on their own).

Every serious email platform ships a prebuilt version of this flow. You are editing copy, not building logic.

Flow 3: Post-purchase

Trigger: an order is placed. Job: turn one order into two — and harvest the byproducts.

The post-purchase sequence is the quiet compounding engine: a thank-you that sets delivery expectations, a check-in timed to arrival, and a review request once the product has been in hand a few days. That last message is where your email platform and your review app shake hands — the review request is an email flow, and the reviews it collects become the social proof on your product pages. (If you have not picked a review app yet, our decision path covers it.) Later, this flow grows replenishment reminders and cross-sells; on day one, thank-you plus review request is plenty.

Which app tier do you actually need?

Here is the load-bearing fact: all three flows run on free tiers. None of this requires a paid plan on day one.

How to choose between them:

• Klaviyo if you expect to scale into serious segmentation and want the platform you will not outgrow. The free tier's 250-contact cap is tight, but it is enough to prove the three flows convert. Budget note: paid pricing climbs with list size, so keep the list clean.
• Omnisend if budget is the constraint. The free tier includes every feature — the caps are volume, not capability — so you can build all three flows exactly as they will run at scale, and the $11.20/month entry is the cheapest paid step in the category.
• Kit if you are a creator whose audience predates the store. The free-to-10,000-subscribers ceiling is unmatched, and the visual automation builder handles these flows fine — but its automations are audience-shaped rather than commerce-shaped, so deep store triggers are lighter here.

Whichever you pick: one platform, one list. The most expensive email mistake new stores report is not a bad app choice — it is fragmenting the list across tools and never quite trusting any of them.

Setup order and the upgrade trigger

Build in the order above — welcome, abandoned cart, post-purchase — because that is descending order of attention and effort-to-value. All three together are an afternoon of copy-editing prebuilt templates.

The upgrade trigger is a named limit, not ambition: contact 251 on Klaviyo, a converting campaign hitting Omnisend's send caps. Hitting a free-tier ceiling with flows that demonstrably drive orders is the healthiest signal there is — the $11.20 or $20 monthly step is being paid for by the list itself. SMS, campaign calendars, and segmentation projects all come later, on top of flows that already work.
