What is ROI?

The formula for ROI is:

ROI (%) = (Revenue – Costs) ÷ Costs × 100

Example: €10,000 revenue – €2,000 costs = €8,000 profit → (8,000 ÷ 2,000) × 100 = 400%.

Where do you find this in Xendy?

  • Dashboard: total realized revenue, number of emails sent, opened emails, and clicks. Revenue shows up as soon as you have an active webshop connection.
  • Sent newsletters: revenue and performance per newsletter.
  • Email automations: revenue and performance per automation and per step.

Key metrics for ROI

  • Revenue: look at both total revenue and revenue per email (RPE) to compare campaigns fairly.
  • Costs: don't just include Xendy — also factor in design costs, hours, and content creation.
  • CTR & conversion: pay attention to how many people click and buy via email — this directly determines your return.
  • Unsubscribes & bounces: lots of unsubscribes or bounces lower your future earnings and hurt your deliverability.
  • CLV: look beyond a single campaign; long-term customer value shows how email contributes to loyal, returning customers.

How to improve your ROI

  • Segment & personalize: don't send everyone the same email. Use behavior, past purchases, or interests to make content more relevant. The more personal, the better your click and conversion rates.
  • Sharp offers: make sure there's a clear benefit — a discount, exclusive access, or bonus. Where it fits, add scarcity or urgency, like "Valid for 24 hours only" or "Last few items in stock".
  • Automations that keep running: set up campaigns that run on autopilot, like a welcome automation for new subscribers, abandoned cart reminders, post-purchase tips or upsells, and re-engagement campaigns for inactive customers.
  • Optimize landing pages: pages need to load fast, be mobile-friendly, and have one clear call-to-action.
  • Test & learn continuously: test subject lines, content, send times, and offers. Small improvements add up fast.
  • Keep your list clean: use double opt-in and regularly remove inactive contacts. This improves deliverability, lowers costs, and boosts engagement.

Quick ROI check (step by step)

  1. Connect your webshop to Xendy: go to Settings → Webshop, choose your platform and complete the connection. After activation, you'll see revenue reflected on your Dashboard, under Sent and under Email automations.
  2. Read the figures per campaign:
    • Newsletters: choose 'Sent' in the left menu, open your campaign and view revenue, sent emails, opens, clicks, bounces, complaints and unsubscribes.
    • Automations: choose 'Email automations' in the left menu and view the sent emails, queue and revenue per automation. Open an automation to see the statistics per step.
  3. Add up your costs: gather costs for the software, hours spent on design, copy, formatting, segmentation and analysis, plus any media or creative costs.
  4. Calculate your ROI: use the formula ROI (%) = (Revenue – Costs) ÷ Costs × 100. Also use RPE (Revenue ÷ Sent emails) or CPA (Costs ÷ number of orders via email) for additional insight. On your Dashboard you'll see 'Revenue per email', showing how much revenue one email has generated on average.

Frequently asked questions

Use the formula: ROI (%) = (Revenue – Costs) ÷ Costs × 100.

Example: €10,000 revenue – €2,000 costs = €8,000 profit → (8,000 ÷ 2,000) × 100 = 400%.

Without a connection, you won't see any email revenue in Xendy. By connecting your shop, you can directly track revenue, RPE (Revenue per Email), and conversions — so you know which campaigns are actually making you money.

Nope. Open rates don't say much since Apple's Mail Privacy Protection (MPP) and only give a rough idea of reach. Focus on clicks, conversions, and revenue instead — those are the numbers that actually tell you something about your return.

Don't just include Xendy's costs — also factor in hours for strategy, formatting, and analysis, external production (copy, design), and any plug-ins. Only counting tool costs gives you a skewed picture of your real ROI.
