How to Write an Email CTA People Actually Click

The email CTA that earns a click is usually the most obvious one, not the most persuasive one. One clear ask, stated plainly, beats three clever options competing for the same click. Most advice about CTAs skips straight to button colours and urgent-sounding phrases. The reader usually just isn’t sure what happens next, and no colour fixes that.

Klaviyo’s 2025 data, cited by Shopify’s Canadian team, puts the average click rate on a promotional email at 1.29%. That’s not a reason to panic. It’s a reason to make the one ask you do get count.

Here’s what actually moves that number, and one habit worth dropping.

One Email, One Ask

Shopify’s own guidance is blunt about this: one email, one objective, one CTA. A second link can support the main one, but it shouldn’t compete with it for attention. Three buttons asking for three different things isn’t generous. It’s confusing, and a confused reader clicks nothing at all.

I think this is the mistake I see most often, because it doesn’t feel like a mistake while you’re writing it. Adding a second CTA feels like giving the reader options. What it actually does is make her stop and decide. That decision alone takes energy most people don’t have left by the third paragraph of an email.

Pick the one thing you actually want from this specific email, whether that’s booking a call, reading a post, or replying with a question. Everything else in the email should build toward that single ask, not compete with it.

Picture an email with a button to book a call, a link to a blog post, and a follow link at the bottom, all in the same send. A reader who’s genuinely interested now has to choose which one you meant most. Most people resolve that kind of ambiguity by closing the email instead of picking one. Cut it down to the single ask that actually matters this week, and the other two ideas can wait for their own email.

Say What Actually Happens When They Click

“Learn More” tells you nothing. “Click Here” tells you even less. Neither one gives the reader a reason to move her cursor. A CTA works when it names the specific thing waiting on the other side of the click: “Book Your Free Call,” “Read the Full Guide,” “Get the Checklist.”

Specific language does something vague language can’t. It lets the reader picture the outcome before she clicks, which lowers the risk of clicking at all. Shopify’s guidance backs this up directly: keep the CTA copy short, three to five words. Lead with a direct verb like get, start, try, or ask.

This is also where knowing exactly who you’re writing to pays off. A CTA that says “Book Your Free Call” only works if a call is actually the next right step for that reader. Getting specific in your copy starts with knowing who’s on the other end of it, not with finding a punchier verb.

Try reading your CTA out loud, on its own, with no context from the email around it. “Click Here” tells a stranger nothing. “See This Week’s Client Spotlight” tells her exactly what she’s about to see. If the button still makes sense read completely out of context, it’s doing its job.

Skip the Fake Deadline

“Act Now” and “Limited Time Offer” show up in almost every CTA template, and they work exactly once. The first time a reader clicks on manufactured urgency, she finds the offer is still there next week. She stops believing your deadlines from then on. After that, the phrase becomes background noise, and eventually it makes her trust the rest of the email a little less too.

Real urgency still works, because it’s true. A cohort that actually closes on a specific date doesn’t need any decoration to make people click. Neither does a seasonal offer that actually ends. Say the actual date and let it do the work. If the deadline isn’t real, don’t manufacture one just to borrow its energy.

I’d rather write a CTA with no urgency language at all than one leaning on a deadline that isn’t real. An honest ask like that outperforms a dishonest one over time, even if the first email doesn’t convert quite as hard.

A genuine deadline usually already exists somewhere in your business, even if you haven’t been naming it yet. Maybe it’s a workshop with a real start date. Or a batch of client spots that actually runs out, because you only have so many hours in a week. Name that real limit plainly instead of borrowing the language of a limit that doesn’t exist.

Make It Impossible to Miss on a Phone

Most of your list is reading on a phone, thumb hovering over a small screen. Nobody’s sitting at a desktop with a mouse, ready to click precisely. Litmus recommends a minimum tap target of 44 by 44 pixels, roughly the size of a fingertip. That’s what makes a button actually easy to hit without a second attempt.

Placement matters just as much as size. Put your CTA near the top of the email, for readers who won’t scroll past the first screen. Repeat it lower down too, if the email runs long enough to need more context first. What doesn’t work is burying the only ask at the very bottom, after three sections of buildup. By then, you’re hoping the reader is still there to find it.

Test how your CTA actually looks and feels on your own phone before you send. If your thumb has to aim carefully, so will everyone else’s.

Colour matters here too, though less than most people assume. A button that blends into the surrounding email is easy to scroll past without registering it as clickable at all. It doesn’t need to match your brand palette exactly. It needs enough contrast against the background that a thumb moving quickly down a screen actually notices it’s there.

The same clarity test applies past your inbox. If you’re not sure your homepage’s main button passes it, the free website clarity tool will tell you in five minutes.
