Tasks

Implementation Phases

Account & E-Commerce Integration

1-2 days

Create your Klaviyo account and connect your e-commerce platform (Shopify, WooCommerce, BigCommerce)
Verify sending domain with DKIM, SPF, and DMARC records
Wait for historical data sync — Klaviyo pulls order history, customer profiles, and product catalog
Set up your sending infrastructure: dedicated sending domain and warm-up schedule

Pro Tip

If migrating from Mailchimp, use Klaviyo's one-click migration tool — it imports lists, templates, and automation history.

Segmentation & Profile Setup

2-3 days

Create core segments: Active Customers (purchased last 180 days), VIPs (top 10% by revenue), At-Risk (no purchase in 90-180 days)
Set up Engaged Subscriber segment for sending (opened or clicked in last 90 days)
Define Custom Properties for profile enrichment: acquisition source, product preferences, LTV tier
Create suppression segments: unengaged 180+ days, bounced, and churned customers
Set up predictive analytics for Expected Date of Next Order and Predicted CLV

Pro Tip

Always send campaigns to Engaged segments only — Klaviyo charges by active profile count, and sending to unengaged contacts wastes money and hurts deliverability.

Flow (Automation) Setup

4-5 days

Build the Welcome Series flow (3-5 emails over 7 days) with a first-purchase incentive
Create the Abandoned Cart flow with 3 emails: reminder (1h), social proof (24h), discount (48h)
Set up the Browse Abandonment flow for visitors who viewed products but didn't add to cart
Build the Post-Purchase flow: order confirmation, shipping updates, review request, cross-sell
Create the Winback flow for customers who haven't purchased in 60-90 days
Set up the Sunset flow to suppress unengaged contacts after 180 days of inactivity

Pro Tip

The Abandoned Cart + Welcome Series generate 50-70% of Klaviyo revenue for most stores. Get these right before building other flows.

Campaign Strategy & Launch

2-3 days

Design branded email templates using Klaviyo's drag-and-drop editor
Set up a campaign calendar: product launches, sales, content, and seasonal sends
Configure A/B testing for subject lines and send times on campaigns
Send your first campaign to the Engaged segment and monitor deliverability metrics
Review flow performance dashboards and adjust timing, content, and discount levels

Pro Tip

Use Klaviyo's Smart Send Time feature on campaigns — it optimizes delivery time per recipient based on their engagement history.

Common Pitfalls to Avoid

Sending to all profiles instead of Engaged segments — destroys deliverability within weeks

Not warming up the sending domain — results in Gmail/Outlook blocking your emails

Setting discount-heavy abandoned cart flows — trains customers to abandon for discounts

Ignoring the Sunset flow — dead profiles inflate costs and hurt sender reputation

Not using conditional splits in flows based on purchase history — everyone gets the same generic email

Success Metrics

Email revenue as percentage of total store revenue exceeds 25% within 90 days

Abandoned Cart flow recovery rate above 5%

Welcome Series conversion rate (email to first purchase) above 8%

Campaign open rates above 25% for Engaged segments

Deliverability: inbox placement rate above 95% across Gmail, Outlook, Yahoo
