Email CTR Calculator

Calculate email click-through rate (CTR) from delivered emails and unique clickers, then compare your result with an optional target and estimate the click gap.

Delivered Emails, Unique Clicks and Target CTR

Emails successfully delivered in the selected campaign or reporting period.
Unique recipients who clicked at least one tracked link.
Your own planning or historical click-rate target.

Delivered emails: 10,000

Unique clicks: 450

Email CTR: 4.50%

Clicks per 1,000 delivered: 45

Target CTR: 5.00%

Target unique clicks: 500

The sample inputs shown here match the default calculator values so the example can be reproduced directly.

Formula

Email CTR = Unique Clicks / Delivered Emails x 100Clicks per 1,000 Delivered = Unique Clicks / Delivered Emails x 1,000Target Clicks = Delivered Emails x Target CTR

Input Checklist

Same scope: Keep delivery, engagement, conversion and cost figures from one comparable campaign or reporting window.Unique metrics: Use unique recipient counts where the calculator requests unique opens, clicks or unsubscribes.Decision context: Read email metrics together instead of optimizing one rate in isolation.

Reporting Note

Email platforms can label click metrics differently and may include or exclude bot/security clicks. Keep the provider, delivered-email scope, unique-vs-total counting method, bot filtering and reporting window consistent before comparing CTR.

No. This calculator uses delivered emails as the denominator. Click-to-open rate (CTOR) uses unique openers and is a separate metric.
Use unique clickers for a recipient-level rate. Total clicks can include repeated clicks by the same person and answer a different question.
Clearer calls to action, stronger message-to-link relevance, focused link choices, segmentation, personalization and a better mobile experience can influence click engagement.
