Create Stunning Opt-In Forms That Convert With These 9 Best Practices

Launch Your Online Business in Just 7 Days

Simply having a great product and a stunning website is no longer the key to success — to run a successful business online, you need an email list.


Marketing your offers to email subscribers that have already shown some interest in what you have to offer is far more likely to lead to sales.


But how do you get those precious email addresses?


With an effective opt-in form of course!

1. What is an opt-in form?

Opt-in Form Definition

An opt-in form is a form that asks visitors for their email addresses, while giving them something of value in return, usually in the form of a lead magnet.


By opting in to your email list, subscribers give you consent to send them marketing campaigns, promotional emails, newsletters, etc.


Most email service providers (ESPs) have spam filters in place, and sending unsolicited emails will land you in the spam folder.


With approximately 122.3 billion spam emails going out each day, opt-in forms help ensure your emails aren’t one of them.


More importantly, an opt-in form is required by email marketing laws.


Violating these laws can lead to some pretty substantial fines and penalties, so make sure to stay on their good side.


Let’s find out what kinds of opt-ins you can create.

1.1. Different types of opt-in forms

These are the 5 most popular types of pop-up opt-in forms:

1. Pop-up

2. Floating bar

3. Splash page

4. Exit-intent pop-up

5. Content form

But which one will work best for your marketing strategy? Let’s find out.

1. Pop-up

  • Popups appear when a visitor arrives on your website or while they’re browsing your site
  • If a visitor has spent some time on your website, they’re likely interested in what you’re offering
  • Present these leads with an opt-in form after a little while to promise them even more value and get their contact details in exchange

2. Floating bar

  • This kind of opt-in is displayed as a bar at the top, bottom, or side of the screen and is locked in place
  • They don’t block any content from the user’s view, but they still get their attention
  • Keep them small, fill them with interesting lead magnets, and watch your list grow!

3. Splash page

  • This takes up the entire screen and is the first page on your site. It’s aimed at communicating value and important information
  • You need to ensure that this opt-in offers your visitor something that they can’t get from your homepage
  • Even if new leads don’t end up purchasing anything after opting in, use email marketing funnels to guide them to conversion later

4. Exit intent pop-up

  • These are triggered when the cursor moves outside the window; it’s the last attempt to convert viewers into subscribers
  • Timing is everything here, as pop-ups like this can irritate potential leads
  • Customized exit-intent opt-ins increase conversion rates, so personalize your opt-in form based on a viewer’s actions

5. Content form

  • These are forms designed to reflect and add value to the content they appear on
  • It’s important that the lead magnet or freebie offered on this form is specific and matches the viewer’s intent that led them to your content
  • Content or in-content opt-in forms require different lead magnets and offers and often appear on blog posts and other resources

1.2. What’s the difference between a pop-up and a landing page?

A popup is a form that pops up in front of the visitor after they’ve been on your site for a certain amount of time.


Whereas, a landing page is an entirely separate webpage with the intent to convert visitors.


Pop-ups tend to be more effective than landing pages — here’s why:

  • Pop-ups have a conversion rate of 3.09% compared to the 2.35% average conversion rate of landing pages
  • If you can display the form at the right time, you’ll get more opt-ins
  • Add an opt-in form to your pop-up, and you get a highly effective method of getting visitor’s attention and enticing them to convert

Now that you know the difference, let’s check out some inspiring opt-in form examples and what makes them successful.

2. 9 tips to create an opt-in form that converts

tips to create an opt-in form

Essentially, you want your opt-in form to encourage new subscribers and generate qualified leads.


There’s no need to reinvent the wheel here, so we’re going to show you exactly what works, as well as some key elements that are guaranteed to grab a visitor’s attention.


Let’s dive into our top tips for creating a high-converting opt-in form.

2.1. Use various opt-in types on your website

Using only one type of opt-in form isn’t effective at encouraging new subscribers.


Different users will consume your content in different ways, so make sure that you’re catering to everyone.


Here’s an example from the Digital Marketing Institute (DMI):

DMI uses a pop-up to announce an offer or an exit intent pop-up to catch potential leads on their way out.


This effectively caters to different branches of their audience.


Some users will close your pop-up without even looking at your offer — to combat this DMI uses a banner to gently remind them to take action:

2.2. Pick an opt-in process

There are two opt-in processes that you can follow — either a single opt-in or a double opt-in.


A single opt-in requires only one action — usually inputting an email address.


The double opt-in involves more than one step.


This opt-in method is used effectively by Sam Dey and consists of just 2 steps:

1. With a pop-up opt-in, he asks for just a first name and an email address:

 pop-up opt-in

2. Here, he just requests that the user verifies their email address:

 pop-up opt-in

The double opt-in process is longer, but it’ll ensure a lower bounce rate and more qualified leads.


Take the time to find which process will work best for your business.

2.3. Personalize your opt-in forms

Creating an opt-in form that’s triggered by a specific action (like abandoning a cart) helps you target users based on their specific interests.


Here’s an example from Everlane — the opt-in form is triggered depending on which section of their website you’re browsing:

This allows them to segment their list more effectively, and to target the right customer with the right message, at the right time.

2.4. Limit form fields

The more time users need to spend to fill in your form, the more likely they are to bounce, so make your opt-in process as simple as possible.


You can limit it to just one field, as Pull&Bear have done:

The email address is the most important!

2.5. Add a bright CTA button

You want the CTA button to be visible immediately — your visitors shouldn’t wonder what you want them to do or where they should sign up.


For example, have a look at how Coschedule uses contrasting colors to make their CTA eye-catching:

Source: CoSchedule.com

Use a color picker to explore which colors would work best for your CTA — just make sure your button copy is clear and easy to read!

2.6. Offer a valuable lead magnet

While a sticky bar reminding users of your weekly newsletter might convince some visitors to subscribe, a pop-up lead magnet won’t have the same effect.


Don’t interrupt your visitors while they’re reading your content to ask them to sign up for your newsletter.


You need to promise them something more valuable!


Here’s a great example — Olivier Roland provides his viewers with a real incentive (more powerful than a newsletter) to get their email addresses:

By presenting them with a free offer they simply can’t refuse, you’ll have no trouble getting them to subscribe!

2.7. Use a content-specific opt-in form

A great way to encourage more email opt-ins is by creating forms and lead magnets that speak directly to the user’s intent.


The more specific the form, the more leads it will gather.


SEMRush’s in-content opt-in form appears on a blog post about why you need a content calendar:

By giving readers a valuable offer that’ll solve their content calendar-related problems, you’ll see a serious spike in lead generation.


At the same time, a hyper-specific offer like this will help build your relationship with your audience.


Website visitors looking to learn about a problem they’re facing will be reminded to subscribe and convinced it’s worth it.

2.8. Pay attention to great design

How the different design elements interact with each other greatly affects the viewer’s response.


Here’s an example from goop:

Like Gwyneth Paltrow’s goop brand, you’ll want to:

  • Opt for a font that’s clean, simple, and easy to read so that your offer comes across as professional
  • Ensure your forms are optimized for mobile devices too since they’re responsible for 54.8% of all web traffic

Images can also be a great addition to your opt-in form, but they need to be relevant to the offer and evoke the right emotion.

2.9. Test, test, and test again

A/B testing is your best friend in the marketing world.


Test everything!


From the copy to the colors, to the layout — the more you test, the better your form will be.


By partnering with a tool like systeme.io, you can easily split test your pages and compare the data:
