Question 1

How do you calculate email marketing ROI?

Accepted Answer

Email ROI = ((Revenue × Gross Margin - Platform Cost) / Platform Cost) × 100. Include both campaign revenue (broadcasts) and flow revenue (automations). With $9,000 total email revenue, 60% margin, and $150 platform cost: (($5,400 - $150) / $150) × 100 = 3,400% ROI.

Question 2

What is a good email marketing ROI?

Accepted Answer

Email marketing typically delivers 3,600-4,200% ROI ($36-$42 per $1 spent), making it the highest-ROI marketing channel. If your email ROI is below 1,000%, focus on improving flows (automated sequences drive 30-50% of email revenue), segmentation, and list quality. Platform costs are low relative to revenue, so even modest list sizes generate strong returns.

Question 3

What are good email benchmarks for ecommerce?

Accepted Answer

Ecommerce email benchmarks: Open rate 35-45%, Click rate (of opens) 2.5-4.5%, Conversion rate (of clicks) 3-8%, Revenue per recipient $0.05-$0.15, Unsubscribe rate under 0.3%. Flows typically generate 2-5x higher revenue per send than campaigns. Klaviyo reports top performers get 30-40% of total revenue from email.

Question 4

How much does Klaviyo cost per month?

Klaviyo pricing by list size (email only): Up to 500 subscribers free, 1,001-1,500 $45/mo, 5,001-5,500 $100/mo, 10,001-10,500 $150/mo, 25,001-25,500 $400/mo, 50,001-55,000 $720/mo. SMS is additional. Alternatives: Mailchimp ($13-$350/mo), Omnisend ($16-$59/mo + custom), Drip ($39-$89/mo).

Question 5

What percentage of revenue should come from email flows vs campaigns?

Accepted Answer

A healthy split is 40-60% from flows and 40-60% from campaigns. If flows are under 30% of email revenue, you're leaving money on the table — set up welcome series, abandoned cart, browse abandonment, post-purchase, and win-back flows. Flows run automatically and typically have higher conversion rates than broadcast campaigns.
