EMAIL ROI: THE METRIC MOST D2C BRANDS DO NOT TRACK

Most brands track total Klaviyo revenue. The more important metric is revenue per subscriber — because it tells you what each new email subscriber is worth to your business, and therefore how much you can invest in list building. Average D2C revenue per subscriber: $1.50–$4.50/month for well-optimised accounts.

FREQUENTLY ASKED

What is average revenue per email subscriber for D2C?

$1.50–$4.50/month for well-optimised Klaviyo accounts. Below $1/month indicates underperformance — typically missing flows or poor segmentation. Above $4/month indicates a well-optimised account with strong product-market fit.

How do I calculate Klaviyo ROI for my business?

Klaviyo-attributed revenue ÷ Klaviyo monthly cost. For a brand generating $30K/month from Klaviyo at $200/month cost, ROI is 15,000%. This is why email is the highest-ROI channel in D2C — the cost is low and the leverage is enormous.

Should I attribute all Klaviyo revenue to email?

Use a 5-day click, 1-day view attribution window in Klaviyo (not the default 7-day click). This more conservatively attributes revenue and gives you a more defensible ROI number. Some Klaviyo revenue would have happened anyway through other channels.
