Email Conversion Rate Calculator
420 of 24,000 delivered emails converted (1.75%).
What is Email conversion?
Email conversion rate is the share of delivered emails that produced the action you wanted, calculated as conversions divided by emails delivered, times 100. Deliver 24,000 emails, get 420 conversions, and the rate is 1.75%.
It is the bottom-line measure of an email campaign. Opens and clicks are signals along the way; conversion is the outcome that actually counts, whether that is a purchase, a signup or a booking.
Using delivered emails as the denominator gives the true end-to-end rate for the whole send, so the figure reflects everything from subject line to landing page, not just the part that got a click.
How to calculate Email conversion
Email conversion = Conversions ÷ Delivered × 100
- Count emails delivered. Use emails that landed, not emails sent, so bounces do not flatter the rate. For example 24,000 delivered.
- Count the conversions. Count the specific goal action driven by the send, for example 420 purchases or signups.
- Divide and multiply by 100. Conversions divided by delivered, times 100. 420 divided by 24,000 is 0.0175, or 1.75%.
- Compare like with like. Keep the same denominator across campaigns so a newsletter and a promo send can be compared fairly.
Worked example
A campaign delivers to 24,000 inboxes and drives 420 conversions.
| Emails delivered | 24,000 |
|---|---|
| Conversions | 420 |
| Result | 1.75% email conversion rate |
420 of 24,000 delivered emails converted, a 1.75% rate. Whether that is strong depends on the send: low for a tight, transactional email to engaged subscribers, but reasonable for a broad newsletter blast.
How to improve Email conversion
- Segment the list so each send goes to people the offer actually fits, which lifts conversion more than any subject-line tweak.
- Keep one clear call to action per email, since competing asks dilute the action you are measuring.
- Match the landing page to the email: a strong click rate with weak conversion usually means the page, not the email, is the leak.
- Clean the list and send to engaged subscribers, because deliverability and relevance both feed the conversion rate.

Frequently asked questions
- What is email conversion rate and how do you calculate it?
- Email conversion rate is the share of delivered emails that drove the action you wanted, calculated as conversions divided by emails delivered, times 100. Deliver 24,000 emails and get 420 conversions and the rate is 1.75%. It measures the bottom line of a campaign, past opens and clicks.
- What is a good email conversion rate?
- There is no universal figure, because it swings with the offer, the list quality and what you count as a conversion. A transactional or tightly segmented send to engaged subscribers converts far better than a broad newsletter blast. The drivers that matter are list relevance, message-to-offer match and how easy the next step is. The most reliable benchmark is your own past rate on similar sends.
- Should I measure conversion on delivered, opened, or clicked emails?
- This calculator uses delivered emails as the denominator, which gives the true end-to-end rate for the whole send. You can also measure against opens or clicks to isolate where the funnel leaks: a healthy click rate but a weak conversion-per-click points at the landing page, not the email. Pick one denominator and stay consistent so your campaigns are comparable.
- Why is conversion rate lower than open or click rate?
- Because conversion sits at the end of the chain: delivered, opened, clicked, then converted, and each step loses people. Open and click rates often run in the double digits while conversion on delivered emails is usually a low single-digit percentage. That is expected, not a problem, since conversion is the hardest action in the sequence.
- How is email conversion different from click-through rate?
- Click-through rate measures who clicked the email, an interest signal partway through the funnel. Email conversion measures who completed the goal, the bottom-line outcome. A campaign can earn lots of clicks yet convert poorly, which usually points the finger at the landing page or offer rather than the email itself.
