MailerLite Automation: Sequences That Grow Revenue on Autopilot

MailerLite’s automation platform is more capable than many brands realise. The visual workflow builder covers the core e-commerce automation use cases cleanly, with trigger options, conditional branches, A/B testing within workflows, and e-commerce integration for cart and purchase events. At MailerLite’s price point — significantly lower than Klaviyo or ActiveCampaign at comparable list sizes — this is a strong value proposition for brands that need solid automation without enterprise-level complexity.

This post is a practical guide to building automation sequences in MailerLite that generate consistent revenue: the core e-commerce workflows, how to use MailerLite’s trigger system effectively, and where the platform’s automation excels — as well as where it has limitations worth knowing about.

MailerLite’s Automation Builder: How It Works

MailerLite’s automation section (called “Automations” in the main navigation) uses a visual trigger-and-step builder. Each automation starts with a trigger event, followed by steps — email sends, wait delays, condition branches, and actions like adding tags, updating subscriber fields, or moving contacts between groups.

The interface is genuinely intuitive. Building a basic welcome series or abandoned cart flow takes under an hour for someone familiar with email marketing concepts, even without prior MailerLite experience.

Available Trigger Types

Subscriber joins a group: The most common trigger for welcome series. When a subscriber opts in via a MailerLite form or is added to a specific group programmatically.

Field value changes: Triggered when a custom field on a subscriber’s profile changes — useful for anniversary-based emails, lifecycle stage changes, or CRM-pushed attribute updates.

E-commerce events: With MailerLite’s Shopify or WooCommerce integration, you can trigger automations from purchase made, purchase not completed (abandoned cart), and specific product purchased events.

Clicks a link in an email: Enables intent-triggered follow-up — if a subscriber clicks a specific link in a campaign, start a targeted follow-up sequence based on that interest signal.

Date-based: Trigger on a subscriber’s birthday, anniversary, or a specific date relative to a custom field.

API/webhook trigger: For advanced use cases, trigger automations via MailerLite’s API when external events occur.

Building the Core E-Commerce Automation Sequences

Welcome Series

The welcome series is the most important automation to build first, and MailerLite handles it well. Set the trigger to “Subscriber joins a group” for your main signup group.

A five-step welcome series structure:

Step 1 — Email (Immediate): Welcome the subscriber. If you offered a discount or lead magnet at signup, deliver it here. Keep this email focused: welcome, deliver the promise, brief brand introduction.

Step 2 — Wait 1 day

Step 3 — Email: Brand story and differentiation. Why you exist, what makes your products different, and what kind of brand you are. This email earns permission for future selling by investing in the relationship first.

Step 4 — Wait 2 days

Step 5 — Condition: Has subscriber made a purchase? In MailerLite, check this with a custom field condition if your e-commerce integration updates a “has_purchased” field, or use a group membership condition if purchasers are moved to a “customers” group. If purchased, remove from welcome series. If not, continue.

Step 6 — Email: Bestsellers or featured products. Three to five products with strong imagery and direct product links.

Step 7 — Wait 2 days

Step 8 — Condition: Purchase check. Same logic as Step 5.

Step 9 — Email: Social proof email — customer reviews, press mentions, UGC. Address the hesitation of a non-purchaser.

Step 10 — Wait 3 days

Step 11 — Email (for non-purchasers): Final welcome series email. Reference the discount or incentive if still unused, create light urgency, single CTA.

Add a tag “completed_welcome_series” at the final step for subscribers who complete the full sequence — this allows you to segment “churned non-purchasers” for later re-engagement with a different approach.

Abandoned Cart Automation

MailerLite’s abandoned cart trigger requires the Shopify or WooCommerce integration to be active. Once connected, the trigger fires when a subscriber’s email is known (they have previously opted in) and they add items to cart but do not complete checkout within a defined window.

Set the abandonment window to 30–60 minutes. Earlier than 30 minutes creates false positives (people still shopping). Later than 60 minutes loses urgency.

Three-email abandoned cart sequence:

Email 1 (1 hour post-abandonment): Cart reminder. Pull in the cart product name dynamically using MailerLite’s custom field personalisation or e-commerce product block. Focus on what they were considering — no pressure, helpful reminder tone.

Wait 20 hours

Condition: Did subscriber purchase? If yes, exit automation. If no, continue.

Email 2 (24 hours): Add social proof or address a common objection. Include a review of the product category in cart. Consider adding a 5–10% discount on this email if your margin allows.

Wait 48 hours

Condition: Purchase check again.

Email 3 (72 hours): Final recovery email. Short, direct, clear CTA. Your best offer if any. After sending, exit the subscriber from this automation regardless of outcome.

Re-Engagement Automation

A re-engagement automation targets subscribers who have not opened or clicked any email in a defined period — typically 90 or 180 days.

Set the trigger to a date-based condition or use MailerLite’s “inactive subscribers” segment as the entry filter for a manual send. A fully automated re-engagement flow is more reliably built with a scheduled automation that runs weekly, checking for subscribers who meet the inactivity criteria.

Structure:

Email 1: “We miss you” — straightforward acknowledgement that they have not been engaged, reminder of what your brand offers, strong CTA. Include an obvious unsubscribe link.

Wait 5 days

Condition: Did subscriber open or click Email 1? If yes, exit re-engagement and return to standard list. If no, continue.

Email 2: Your very best offer or most compelling piece of content — this is your final attempt. Offer an incentive. Include clear messaging: “If this is not for you, we completely understand — no hard feelings.”

Wait 7 days

Action: If no engagement, remove from active list or unsubscribe. Do not continue sending to completely inactive contacts.

Using MailerLite’s E-Commerce Integrations

MailerLite offers direct integrations with Shopify and WooCommerce, plus a Zapier connection for other platforms. The Shopify integration syncs contact data, purchase history, and cart events into MailerLite.

Once the integration is live, you can:

Trigger automations from purchase events
Use purchase data in email personalisation (last purchased product, total spend)
Create segments based on purchase count, last purchase date, and order value
Build a post-purchase automation sequence triggered by the “purchase made” event

The integration is less deep than Klaviyo’s Shopify connector — particularly around browse abandonment (which requires separate site tracking setup) and product feed syncing for dynamic recommendation blocks. For most small to mid-sized e-commerce brands, however, the available integration depth is sufficient for building the core automation stack.

Analytics for Automation Performance

MailerLite shows per-email performance within each automation: sends, opens, clicks, and unsubscribes. For revenue attribution, the Shopify integration provides revenue generated per automation when purchase events are tracked correctly.

To evaluate automation health, look at:

Completion rate: What percentage of contacts who enter an automation complete all steps?
Conversion rate per email: For e-commerce automations, what percentage of recipients who received each email made a purchase within 7 days?
Drop-off points: Where are contacts exiting automations? High exit after Email 2 suggests that email needs revision.

MailerLite’s analytics are clear and sufficient for optimisation decisions, though they are less detailed than Klaviyo’s flow analytics, which offer cohort-level analysis and more granular revenue attribution.

Where MailerLite’s Automation Excels and Where It Has Limitations

MailerLite excels in:

Ease of use — the automation builder is one of the most intuitive in the market
Price efficiency — building a solid automation stack costs significantly less than comparable Klaviyo functionality
Core sequence coverage — welcome, abandoned cart, post-purchase, and re-engagement all work well
Landing page and form integration — MailerLite’s native landing pages feed directly into automations cleanly

The limitations to be aware of:

No native predictive analytics (no predicted LTV or churn probability)
Browse abandonment requires additional setup — it is not as seamless as Klaviyo’s native implementation
Conditional logic depth is lower than ActiveCampaign or Klaviyo — complex multi-path flows with many branches become harder to manage
Product recommendation blocks are less sophisticated than Klaviyo’s dynamic product feeds

For brands under £400k in annual e-commerce revenue, MailerLite’s automation capability covers what you need at a price that makes sense. At higher revenue scales with more complex automation requirements, the platform limitations start to constrain what is achievable.
