Get your three core email rates at once. Enter delivered, opens and clicks to see open rate, click-through rate and click-to-open rate together.

Your email rates
…

Your three core email metrics work together: open rate shows whether your subject lines and sender reputation earn the open, click-through rate (CTR) shows whether the whole email drives action, and click-to-open rate (CTOR) isolates how compelling your content is for the people who actually opened. This free calculator gives you all three from one set of numbers, so you can see the full funnel at a glance.

Frequently asked questions

What is a good email open rate?

It varies by industry, but 20–40% is a common healthy band, and engaged creator audiences often sit higher. Compare to your own trend rather than a fixed target, especially since privacy features now inflate some open numbers.

What is the difference between CTR and click-to-open rate?

Click-through rate (CTR) is clicks divided by delivered, so it reflects the whole email including the subject line. Click-to-open rate (CTOR) is clicks divided by opens, so it isolates how persuasive your content and links are for people who opened. CTOR is the cleaner test of the email body itself.

How do I improve these rates?

Lift opens with clearer subject lines and a clean, engaged list; lift clicks with one strong call to action and relevant content. Segmenting and sending to the right people moves all three at once.

How can I send better newsletters?

On Klairova you can grow an owned audience, segment it, automate sequences and send newsletters, free to use, so you keep more of what your audience earns you.
