Email marketing generates more revenue per pound spent than any other channel for Shopify stores — typically £3–£6 back for every £1 of platform cost. But that equation only holds if the platform cost is justified. Klaviyo’s February 2025 billing change made every active profile chargeable, so bills now climb with list size from a $20/month entry plan. Systeme.io’s permanently free plan covers the same core workflows at $0.
This guide covers the complete free Shopify email setup: platform choice, Shopify connection, the four essential automations, and campaign structure.
Which Free Email Platform to Use
Three genuine free options exist for Shopify stores in 2026:
Systeme.io — free for 2,000 contacts with unlimited sends (recommended for most stores)
- 2,000 contacts, unlimited sends — permanently free
- Full automation sequences with conditional logic
- Sales funnels, CRM, affiliate management included
- Shopify native integration + Make.com webhook support
- Klaviyo comparison →
Shopify Email (best for simplicity)
- First 10,000 emails/month free, then $1/1,000
- Native Shopify integration — no third-party account needed
- Limited automation (abandoned cart, welcome only)
- No CRM, no funnels, no advanced segmentation
- Best for: stores that only need campaigns + basic flows
GetResponse (best paid alternative under 5,000 contacts)
- Free plan: 500 contacts, 2,500 sends/month
- Paid from $19/month for 1,000 contacts
- Advanced AI copywriting, webinars, landing pages
- 60–70% cheaper than Klaviyo at equivalent list sizes
- Try GetResponse free — engagement-based billing, 30-day trial →
For stores under 2,000 contacts that want full automation capability at $0, Systeme.io is the correct choice. The rest of this guide covers Systeme.io setup.
Connect Systeme.io to Shopify
Two methods — use whichever fits your setup:
Method 1 — Native Integration (5 minutes)
In Systeme.io: Settings → Integrations → Shopify → Connect
Enter your Shopify store URL. Systeme.io connects via OAuth. Once connected, Systeme.io can:
- Automatically add customers to your list on purchase
- Tag contacts based on products purchased
- Trigger automations from Shopify purchase events
Method 2 — Make.com Webhook (more control, 15 minutes)
For stores that want to trigger Systeme.io sequences from specific Shopify events (abandoned checkout, specific product purchases, subscription renewals), use a Make.com — free, 1,000 ops/month scenario with a Shopify webhook as the trigger and a Systeme.io HTTP module to create/tag contacts.
This is the method that powers the abandoned cart recovery sequence — see the abandoned cart guide for the full setup.
The Four Essential Automations
Every Shopify store should run these four sequences. Combined, they typically account for 20–35% of total email revenue.
Automation 1 — Welcome Sequence
Trigger: New subscriber (form opt-in, popup, or checkout opt-in) Length: 3–5 emails over 10 days Goal: Set expectations, build brand trust, drive first purchase
| Timing | Content | |
|---|---|---|
| Email 1 | Immediately | Welcome + your brand story + 3 best sellers |
| Email 2 | Day 3 | Social proof — reviews, customer results |
| Email 3 | Day 7 | Your most useful guide or content piece |
| Email 4 (optional) | Day 10 | First purchase incentive or your most popular product |
In Systeme.io: Create automation → trigger: Contact subscribes to tag welcome → add email steps with delays.
Automation 2 — Abandoned Cart Recovery
Trigger: Shopify checkout abandoned webhook via Make.com Length: 3 emails over 72 hours Goal: Recover 5–15% of abandoned checkouts
See the full setup: Shopify Abandoned Cart Recovery Free 2026.
Automation 3 — Post-Purchase Sequence
Trigger: Customer completes a purchase (Shopify native integration or Make.com webhook) Length: 3–4 emails over 21 days Goal: Reduce refunds, build loyalty, generate reviews, cross-sell
| Timing | Content | |
|---|---|---|
| Email 1 | Day 1 | Order confirmation context + what to expect |
| Email 2 | Day 5 (after delivery) | How to get the most from the product |
| Email 3 | Day 10 | Review request — link to your Trustpilot or Google reviews |
| Email 4 | Day 21 | Cross-sell: “customers who bought X also love Y” |
The review request email (Email 3) is often the highest-ROI single email any Shopify store can send. Reviews compound over time and drive organic conversion rate improvements that persist indefinitely.
Automation 4 — Win-Back Campaign
Trigger: No purchase in 90 days (set up as a segment in Systeme.io) Length: 2 emails Goal: Re-engage lapsed customers before they disengage permanently
| Timing | Content | |
|---|---|---|
| Email 1 | Day 90 | ”We miss you” — what’s new + your best current offer |
| Email 2 | Day 97 | Final re-engagement with an incentive |
After Email 2, move non-openers to a suppressed segment to protect your sender reputation. Continuing to send to disengaged contacts damages deliverability for your active list.
Campaign Structure (Non-Automation Emails)
Beyond automation, most Shopify stores benefit from 2–4 broadcast campaigns per month:
- New product announcement — when you add new products or restock popular ones
- Seasonal/promotional — sale events, product launches, seasonal relevance
- Content/value email — a useful guide, tip, or resource (keeps list warm without selling)
- Flash sale or limited offer — highest short-term revenue potential, use sparingly
Rule of thumb: more than 4 campaigns per month increases unsubscribe rates for most Shopify audiences. Two campaigns per month is a sustainable baseline that keeps the list warm without fatiguing it.
Deliverability Fundamentals
Free tools only work if your emails reach the inbox. Four things matter most:
-
Use a custom sending domain. In Systeme.io settings, add your own domain (e.g.
hello@yourstore.com) and configure the required DNS records (SPF, DKIM, DMARC). Never send email marketing from a generic address — inbox placement drops significantly. -
Warm up new domains gradually. If you’ve never sent email marketing from your domain before, start with 50–100 emails/day and increase over 2–4 weeks before sending to your full list.
-
Clean your list before migrating. If migrating from Klaviyo, export only contacts who have opened at least one email in the last 180 days. Re-importing disengaged contacts immediately damages your sender reputation on the new platform.
-
Set up Google Postmaster Tools (free) to monitor your sender reputation with Gmail. Free, takes 5 minutes to set up, tells you if your domain is being marked as spam before it becomes a significant problem.
Free Stack vs Klaviyo: Honest Assessment
Systeme.io’s free plan is a genuine replacement for Klaviyo for stores that primarily use automation sequences and broadcast campaigns. It is not a replacement if you actively use Klaviyo’s predictive CLV segments, RFM scoring, Shopify product recommendation blocks in emails, or SMS marketing.
| Feature | Systeme.io Free | Klaviyo |
|---|---|---|
| Contacts | 2,000 | 251 on free, then paid |
| Email sends | Unlimited | Limited on free |
| Automation sequences | Full | Full |
| Conditional logic | Yes | Yes |
| Shopify integration | Yes | Yes (deeper) |
| Product blocks in email | No | Yes |
| Predictive CLV / RFM | No | Yes |
| SMS marketing | No | Yes (paid add-on) |
| Monthly cost at 2,000 contacts | $0 | ~$60–70/month |
For the typical Shopify store under £500k/year revenue running welcome, abandoned cart, and post-purchase flows: the free stack delivers equivalent outcomes at $0 vs £720–840/year.
