How Many Links Should You Include in a Marketing Email?

Add too many links and readers freeze, unsure what to click first. Add too few and an engaged reader has no way to act on their interest. Like most email questions, there's no single correct number. The right count depends on the type of email, its goal, and how much choice actually helps versus overwhelms the reader. This guide breaks down how to find that number for each type of email you send.

Why "More Links" Doesn't Mean "More Clicks"

It seems logical that more links should create more chances for a click. In practice, the opposite often happens. When a reader is given too many choices, they experience what's often called choice paralysis. Instead of picking one thing to click, they hesitate, decide nothing feels urgent enough to choose right now, and close the email without clicking anything at all.

A single, obvious link almost always outperforms five competing ones, because it removes the decision entirely. The reader either wants that one thing or they don't, and there's nothing else pulling their attention away.

Match Link Count to Email Type

Promotional and Sales Emails: One Primary Link, Repeated

The strongest promotional emails use just one destination, but link to it more than once, such as in the header image, the main CTA button, and a text link near the bottom. This isn't the same as adding multiple different links. It's giving the reader several chances to click the same action, no matter where their eyes land in the email.

Newsletters and Roundups: Multiple Links Are Expected

A weekly roundup or "here's what's new" email is a different case. Readers expect to see several distinct pieces of content, and each one reasonably needs its own link. Here, more links aren't competing distractions, they're the actual content structure the reader signed up for. The key is making sure each link is clearly tied to its own headline or description, not just a bare word buried mid-paragraph.

Product Launch Emails: A Small, Curated Set

Launch emails often benefit from 2 to 4 links, such as "shop the collection," "read the full story," and one or two individual product links. This gives interested readers a couple of ways to engage without turning the email into a full catalog.

Transactional Emails: Only the Links the Reader Needs

An order confirmation or shipping update should only include links directly related to that transaction, like "track your order" or "view your receipt." Adding unrelated promotional links here often confuses the reader and can look unprofessional, since they opened the email expecting one specific piece of information.

General Benchmarks by Email Type

The Difference Between Repeated Links and Competing Links

This distinction matters more than the raw number on the page. A promotional email with the same "Shop Now" link placed in three spots isn't adding choices, it's adding convenience. A promotional email with three different links pointing to three different collections is adding competing choices, and that's where click-through rate usually drops. Count distinct destinations, not the total number of clickable elements, when deciding whether you've added too many links.

Where Links Are Placed Matters as Much as How Many

A link buried in the middle of a dense paragraph gets far fewer clicks than the same link presented as a standalone button. Before worrying about the count, make sure your most important link is visually obvious, ideally as a button with contrasting color and clear surrounding white space, positioned where the reader doesn't need to scroll far to find it.

Mobile Screens Punish Cluttered Link Layouts

On a small screen, several links placed close together become difficult to tap accurately, and a misplaced tap can send a reader to the wrong page entirely. If your desktop preview looks fine with six tightly packed links, check the same layout on a phone before sending, since spacing that looks reasonable on a large monitor often becomes cramped and error-prone on mobile.

Signs You Have Too Many Links

• Click-through rate is spread thin across many links, with no single link getting meaningful traction
• Heatmap or click-tracking data shows clicks concentrated near the top, with links further down getting almost none
• Readers reply asking what they were actually supposed to do in the email
• Overall click-through rate is lower than similar emails with fewer links

Signs You Have Too Few Links

• An engaged, high-intent audience (like a newsletter roundup) has no way to explore beyond the first item
• Readers who clearly want more information have nowhere to go from the email itself
• Click-through rate is flat even though open rate and read time both look strong

How to Test Link Count on Your Own List

1. Pick one recurring email type, such as your product update email.
2. Send a version with a single, repeated primary link to half your list.
3. Send a version with two or three additional secondary links to the other half.
4. Compare total click-through rate and, where possible, downstream conversions, not just clicks on any single link.
5. Repeat the test across a few sends, since link performance can shift depending on the specific content or offer in that particular email.

Final Thoughts

There's no fixed number of links that works for every email. What matters is matching the link count to what the reader expects and needs from that specific type of email. A single, repeated link usually wins for direct-action emails, while a curated set of several links makes sense for roundups and newsletters where choice is part of the value. Focus less on hitting a target number and more on removing anything that competes with the one action you most want the reader to take.
