What Is Opt-In Email Marketing: Definition, Example, and Template
Ever wanted to know how to get started with email marketing to grow your online business? Read this guide to get all the basics and start today!

When you visit your mailbox every day, do you carry a stack of unsolicited flyers, postcards, circulars, and other advertisements?
That鈥檚 called outbound marketing. It鈥檚 a spray-and-pray approach that marketers use to spread their messages as far and wide as possible. They know that most of their ads wind up in the recycling bin.
Opt-in email is a completely different form of marketing. It鈥檚 an inbound approach that Seth Godin termed 鈥減ermission marketing.鈥 In other words, you鈥檙e getting your prospect鈥檚 permission to receive communications from your brand.
Why is that important?听
Because your prospects are far less likely to send your messages to the virtual equivalent of the recycling bin. They鈥檝e given you their email addresses for the express purpose of receiving content from you.
Opt-in email isn鈥檛 just more effective. It鈥檚 also more ethical. Cluttering up email inboxes with unsolicited messages is a surefire way to ruin your brand image and reputation. People just don鈥檛 respond well to it, especially since 269 billion emails get sent every single day.
You don鈥檛 want to be part of the noise. You want to connect with your customers and convince them to sign up for your online courses. 听
Opt-In Email Definition

Opt-in email is defined as an email that a brand sends after a consumer willingly provides his or her email address. Brands can collect email addresses in myriad ways, but usually they use forms on their websites as well as incentives, such as free downloads.
Think of it as a way to authenticate your email list. Instead of sending emails blindly to people who might not have any interest in your online courses, you鈥檙e spending time only on people who already know who you are and who want to hear from you.
What Is Opt-In Email Marketing?听
Opt-in email marketing is a marketing campaign that uses permission-based to capture email addresses from willing consumers. Once you have a potential customer鈥檚 email, you can add it to a marketing list based on the customer鈥檚 position in the sales funnel.
For instance, if your prospect signs up for your email list during his or her first interaction with your brand, you might segment that consumer into a list that introduces your online courses and provides actionable tips for interested consumers.
However, if your prospect joins after buying a course, you could send emails about getting the most out of your course material or about applying the information you teach to the real world.
Opt-in email marketing isn鈥檛 just a way to capture email addresses so you can blast prospects with sales copy. In fact, that鈥檚 the worst way to use it.
Instead, use opt-in email marketing to nurture your prospects through the sales process.
- Invite prospects to interact: Let your email marketing recipients know where to find you online, from your social media accounts to your blog.
- Encourage customers to convert: Provide sound reasons why a prospect should buy one of your courses. Use real-world examples to illustrate your points whenever possible.
- Follow up with prospects: If a prospect abandons his or her shopping cart or goes inactive for a while, reconnect with a nurturing email that reminds him or her that you exist.
- Send promotions: Offer discounts and other promotions that encourage prospects to buy your course for the first time or to buy a subsequent course.
Set up your opt-in email marketing campaign based on your specific objectives. Every course creator has different goals, so you don鈥檛 want to copy someone else鈥檚 campaign. Instead, think of the goals you want to reach, then design emails that help push customers to help you reach them.
- Gain brand visibility: If you want to establish yourself as an authority figure in your industry and make more people aware of your brand, encourage your email opt-ins to share your messages. The more people forward your emails, the more signups you get.
- Boost sales: Use promotions, bundles, and discounts to get people to finally hit the 鈥渂uy鈥 button.
- Increase upsells: Encourage customers to buy multiple courses and other digital products.
- Check on progress: Find out where your customers are in their online courses and whether they need any assistance or have any feedback.
- Solicit reviews: Ask your customers to review your courses online. You鈥檒l get backlinks as well as more brand visibility. Plus, prospective customers will feel more comfortable buying from you. In fact, nearly 85 percent of respondents to a study stated that they as much as they valued recommendations from friends.
You鈥檒l continually adjust your email marketing campaign as you gain more subscribers and measure the results. Even though you鈥檙e using an opt-in email approach, you can鈥檛 always predict whether customers will open, read, or engage with your emails.
Keeping track of key metrics can help.
- Open rates: If customers don鈥檛 open your emails, you might need to create more compelling subject lines or introduce an incentive early in your emails.
- Engagement rates: Customers open your emails, but they don鈥檛 do anything else. If this happens, add more attractive calls to action using freebies and discount codes. Get people to click on links .
- Conversion rates: Do customers buy your online courses after reading your emails? You can track conversions through email and landing pages to figure out how well you鈥檙e converting.
If you鈥檙e struggling to gain traction with your email marketing campaign, you might need a stronger lead magnet.
For instance, let鈥檚 say that you design online courses for fitness buffs. You could create a lead magnet like a PDF filled with illustrated exercises and pro tips. Other options could include video demonstrations of exercises or a free checklist for people who are interested in HIIT.
Spam Versus Opt-In Email
Spam is an ugly word, right? You don鈥檛 want people to associate it with your brand.
Unfortunately, even when you use opt-in email, your emails could be perceived as spam. It happens when you use overly promotional, salesy language, or when you send too many emails in too short a time period.
Additionally, if you don鈥檛 use the opt-in strategy at all, you risk your emails getting diverted to spam folders. If your recipients report your emails as spam, their email clients might automatically assume that everything you send is spam. That鈥檚 the wrong way to start an email marketing campaign.
So what differentiates spam from opt-in emails?听
First, of course, is the permission factor. When you collected an email address, did you get permission from the person who owns it? In other words, did it come via a form or other email-collection tool? If not, you might not want to use it.
Secondly, were you clear about the types of messages the consumer would receive?
It鈥檚 easy to collect email addresses via a form if you promise rainbows and unicorns. Unless you 听can actually deliver rainbows and unicorns, however, you鈥檙e being disingenuous, and your subscribers will quickly catch on to your game.
When you collect email addresses through an opt-in form, make two things perfectly clear:
- Email type: What messages will the subscriber receive? Mention that you send insider tips and tricks, promotions and sales, or other content (but make sure it鈥檚 true).
- Frequency: How often should subscribers expect to hear from you? If you promise to email only once per month, but you send emails every day, you鈥檒l get some backlash.
If you follow those rules, you can separate your email campaign from the dreaded spam word.
Keep in mind that black-hat email marketing techniques will automatically classify your messages as spam. For instance, don鈥檛 ever buy an email list. It鈥檚 an ineffective marketing technique, for one, but it鈥檚 also unethical and spammy.
Additionally, don鈥檛 break your own rules. If you decide to change the types or frequency of emails you send, let your subscribers know so that they can opt out if they wish.
There鈥檚 another factor that helps define spam.
Let鈥檚 say that you do some research on LinkedIn to find people who might be interested in your course on leadership. You find a few people who seem like great leads, so you send them InMail or an email message to introduce yourself and your online courses.
The recipient didn鈥檛 opt in to receive your email, but it鈥檚 not spam. Why? Because you sent a single email to a single individual.
For emails to qualify as spam, they must be sent in bulk. In other words, you send out a mass email to a bunch of email addresses at the same time. You don鈥檛 personalize any of the messages.
When you send single emails to people who might be interested in your digital products, and when you based on what you know about the recipients, you鈥檙e simply . It鈥檚 not the fastest way to boost conversions, but it鈥檚 not shady, either.
What Is Opt-Out Email?

Opt-out email is a marketing strategy that allows consumers to opt out of email campaigns that no longer interest them. It sounds like a bad thing, but opt-out email isn鈥檛 necessarily negative. In fact, it can make your email campaign stronger.
There are two main points at which you can give your subscribers the opportunity to opt out of emails from your brand:
When Signing Up for Something Else 听
Let鈥檚 say that you collect email addresses from people who want to download a or who buy another digital product from you, such as an ebook. Many entrepreneurs use this opportunity to add those emails to their email marketing lists.
It鈥檚 not a bad strategy, but it can backfire.
Maybe the consumer wanted the free white paper or the ebook, but does not want to receive sales emails. That鈥檚 understandable. You can include an option to opt out of your email list right then so you don鈥檛 have to worry about upsetting people or getting your emails flagged as spam.
When Sending Emails 听
Every email you send should include an 鈥渦nsubscribe鈥 option at the end. If a user clicks on that button, he or she can opt out from receiving future emails from you.
While it might sting a bit, it鈥檚 better than having your emails consistently flagged as spam. Consumers know what they want to read, and if they鈥檙e not interested in your messages, you鈥檙e better off letting users unsubscribe.
You don鈥檛 want users to opt out from your email list, but it happens to every entrepreneur. Your message will resonate with some consumers, but others won鈥檛 respond as positively. That鈥檚 okay. Just focus on nurturing the subscribers who continue to open and engage with your emails.
Opt-In Email Templates and Examples听
Now you鈥檙e ready to capture email addresses from potential subscribers. You鈥檒l need an opt-in email template that allows you to collect those addresses effectively on your website, blog, or other web assets.
A simple form that you put in your sidebar or at the top of your page can work well. However, you have several other options, as well, depending on your website鈥檚 setup and the email service you use to send marketing emails.
Popups听
Many entrepreneurs use pop-ups on their websites to collect email addresses. A pop-up is a window that appears over your usual website content. It invites the user to sign up for your email marketing campaign and often includes an incentive.

As you can see, uses a pop-up to collect email addresses. It鈥檚 triggered when the user attempts to exit the page. You can also set email pop-ups to appear after a user spends a certain amount of time on a page or when the user visits more than one page on your website.
Below Your Products听
The area just beneath the products you list on your home page or sales page can also include an email signup form.

uses this tactic on its homepage. After you scroll past several sneakers and other shoes, you see this invitation. Users can click on the 鈥渟ignup鈥 link at the bottom, provide their email addresses, and receive special promotions from Nike.
You鈥檒l notice that Nike uses the best practices we mentioned above. The company lets users know exactly what type of content they can expect to receive after they sign up.
You can put your email template on just about any page of your website or blog. Consider adding them to social media, as well, so you can capture your audience there.
Building a Template听
Once you decide where you want to put your email template, you must design the template itself. It should include a combination of buttons, graphics, and text that encourage the user to opt in.
- Create a headline. You can use something simple like Nike鈥檚 鈥淪ign Up for Nike Email鈥 or try something a little more creative. Make sure your headline aligns with your brand鈥檚 message and your course content. You can also create a graphic headline that attracts attention.
- Describer the perks. Tell users exactly what they can expect to get in exchange for providing their email addresses. You can offer an incentive, such as a free download, as well as mention coupon codes and any other promotions you might send their way.
- Add a button. Buttons make it obvious that you want the user to click. You can either include the button in your email template or put it at the end of your form, depending on how you鈥檝e designed it.
- Collect the information. Keep in mind that most people won鈥檛 fill out detailed questionnaires just to get a free white paper. Asking for the person鈥檚 name and email address should prove sufficient.
The design is completely up to you. Add lots of color and images if that aligns with your brand, or keep it simple and subdued.
Keep in mind, however, that consumers will pay more attention if your email opt-in template stands out. Consider using a bright color for your background or formatting the text in bold or a different color.
You can also A/B test your email forms. Try two different forms on separate pages to see which one converts the best. You can run multiple tests over several weeks or months to figure out exactly which strategy will work best for your prospects.
Forms听
Several different types of email opt-in forms exist, each of which produces a slightly different result. Choose the form type that feels most comfortable for you.
Unconfirmed Opt-In听
Also called a 鈥渟ingle opt-in,鈥 this type of form collects the email address immediately when the user fills out the form. The address gets added to the email marketing database, and the user will receive emails from that point forward.
It鈥檚 the easiest type of form to use, and it often results in a larger list. However, if a user forgets about filling out your form, he or she might view future emails as spam. You can take that risk, but you might want to consider one of the other form types if you want to keep your email list as clean as possible.
Confirmed Opt-In听
This type of form is also called a 鈥渄ouble opt-in鈥 because it requires two steps. First, the user provides his or her email address and other information in the form. Afterward, he or she receives an email confirmation.
The email doesn鈥檛 get added to the entrepreneur鈥檚 database until the user clicks on that link. In other words, each subscriber has two opportunities to opt out from the list. If someone accidentally fills in your form or has second thoughts, there鈥檚 no harm done.
Email Address Authentication听
A form that includes email address authentication helps guard against incorrect information. You鈥檝e made mistakes while typing your email address, phone number, and other information before, so your subscribers might make the same mistake.
After users fill out your email opt-in form, they will see a page that urges them to check their email. It will also invite them to fill out the form again if they don鈥檛 receive a confirmation via email. You won鈥檛 miss out on potential subscribers due to inaccurate information, and your subscribers will be more likely to remember signing up for your list.
Advantages of Opt-In Email听

Once you create an opt-in email campaign, you鈥檒l gain access to several advantages that can help you market your online course more effectively.
- Streamline your marketing approach. Create drip email campaigns that help you nurture your leads gradually toward a sale and that keep them engaged with your business.
- Gain access to interested prospects. An opt-in program ensures that everyone who lands in your email database wants to receive messages from you. You鈥檙e not wasting anyone鈥檚 time, and you know you鈥檙e marketing to the right people.
- Automate your marketing campaign. You can , and you can write emails in advance, then schedule them for distribution later. You鈥檒l save time that you can use to create more online courses.
- Avoid getting classified as spam. Once email clients perceive your messages as spam, you鈥檒l struggle to get your emails seen, let alone read.
- Segment your audience. Add emails to different lists based on the behaviors or activities that triggered the opt in, such as signing up to receive a free download or buying one of your other digital products.
- Build a following. Your audience matters when you want to make money with online courses. Your email audience can easily extend over into social media and your blog if you promote those assets in your emails.
- Educate your audience. People love to learn. Consider creating an email course that whets your audience鈥檚 appetite for paid courses down the road.
The Rise of Implicit Opt-In听

has become increasingly popular in the marketing space. It鈥檚 defined as an opt-in email form that that鈥檚 unrelated to the email marketing campaign, but that automatically adds the user to the database.
Let鈥檚 say that you sell fine-art photography and you鈥檝e created an online course for beginning photographers. Someone buys a photo from you, and during the process, you add the email address to your marketing database.
You鈥檒l include language in the form or your that lets the user know that downloading the product gives his or her implicit consent to receive marketing emails. There isn鈥檛 a direct correlation between your email marketing campaign for your photography online course, but the user will begin to receive marketing emails.
It鈥檚 a good strategy for quickly building a huge database of emails, but it鈥檚 also a little risky.
For one thing, some people don鈥檛 appreciate implicit opt-in. They鈥檒l forget that they were included in your email database, and they might get angry when they start to receive promotional emails from you.
The risk increases when the initial opt-in doesn鈥檛 have much to do with the email marketing campaign. For instance, someone who buys a fine-art photograph might not want to learn photography. They simply want to appreciate it.
You can use implicit opt-in, but make the outcome as obvious as possible.
Best Practices for Gathering Permission-Based Email Subscriptions听
Now that you鈥檙e ready to collect email addresses using a permission-based opt-in program, use these tips to increase engagement and improve the outcome of your efforts.
- Add your email opt-in form to every page on your website and blog. You want as many people as possible to see it.
- Segment your audience based on their behavior. For instance, someone who has never interacted with your business before doesn鈥檛 belong on the same list as a person who has bought one of your courses in the past.
- Use double and other strategies if you want to build the strongest list possible. When you narrow down your list to the people who truly want to be there, you鈥檒l build an audience of highly engaged, ready-to-convert leads.
- Mix up your email content. One week, for instance, you might send a coupon code for a discount on your courses. The next week, send an educational email that teaches your subscribers how to solve a problem or reach a goal.
- Track your metrics. Pay careful attention to open rates, engagement rates, bounce rates, and other metrics that might inform future efforts.
- Invite subscribers to share your emails. Ask them to forward them to interested family and friends. Those people might become direct subscribers.
- Never forget a call to action. You want each email to drive your subscribers toward a specific next step, such as buying your course.
