Email Click-Through Rate Calculator
Measure the percentage of delivered emails that received at least one link click. Use it to gauge content relevance and call-to-action effectiveness in any email campaign.
About this calculator
Email click-through rate (CTR) tells you what share of successfully delivered emails prompted recipients to click a link inside. The formula is: CTR = (emailClicks / emailsDelivered) × 100. For instance, 350 clicks from 7,000 delivered emails yields a CTR of 5%. CTR is distinct from open rate — it measures engagement beyond simply opening the message. It reflects how compelling your copy, design, and call-to-action are. Industry averages typically range from 1% to 5% depending on sector, but e-commerce, SaaS, and media newsletters each have their own benchmarks. Tracking CTR over time reveals whether list health, subject lines, or content changes are driving or dampening audience engagement.
How to use
Imagine you sent a promotional email to 10,000 subscribers. Of those, 9,500 were successfully delivered and 285 recipients clicked a link. Enter 285 as Email Clicks and 9,500 as Emails Delivered. The calculator computes: CTR = (285 / 9,500) × 100 = 3.0%. If a follow-up campaign with improved button placement delivered 380 clicks from the same list size, CTR rises to 4.0% — a 33% relative improvement, confirming the design change worked.
Frequently asked questions
What is a good email click-through rate for marketing campaigns?
Industry benchmarks for email CTR typically range from 1% to 5%, with an average around 2–3% across sectors. B2B newsletters often see higher CTRs (3–5%) because subscribers are more intentionally opted-in, while mass retail campaigns may hover near 1–2%. The best benchmark is your own historical average — consistent improvement matters more than hitting an industry number. Segmented, personalized emails routinely outperform blasts by 2× or more.
How is email click-through rate different from click-to-open rate?
CTR is calculated against all emails delivered, making it an absolute measure of campaign reach and engagement combined. Click-to-open rate (CTOR), by contrast, divides clicks only by emails that were opened, isolating whether the email body itself drove action. A campaign can have a low CTR but a high CTOR if few people opened it, suggesting a subject line problem rather than a content problem. Using both metrics together gives a fuller picture of where subscriber drop-off occurs.
Why did my email click-through rate drop even though open rates stayed the same?
Stable open rates with falling CTR usually point to a content or design issue rather than a deliverability or subject line problem. Common culprits include a weak or buried call-to-action, too many competing links that dilute focus, or content that no longer matches what your audience expects. List fatigue — where engaged subscribers have already converted and less-engaged ones remain — can also suppress clicks over time. Auditing your email layout, testing a single prominent CTA, and re-segmenting your list are the most effective first steps.
