What Is Opt-in Email Marketing?

Single Opt-in: One-Step Welcome

Single opt-in is where someone gives you their email address, and you start sending them emails. 

For example, someone might visit a tech gadget website and drop their email address to get updates on the latest gadgets. Or they might go to a music festival, see a booth for a popular band, and find a sign-up sheet to get updates on their future concerts and albums.

Single opt-in is straightforward, but it has a couple of downsides. For one, you might end up with fake or incorrect email addresses since people don’t have to confirm their addresses. Plus, some people might forget they willingly signed up and get annoyed when they start getting your emails. This isn’t great if you’re trying to build a good relationship with your audience.

Double Opt-in: Confirmed Connection

With double opt-in, after someone gives you their email address, you send them a confirmation email to make sure they genuinely want to be on your list. They click on a link to confirm, and then they’re in. 

This way, the person browsing that tech gadget website gets an email to confirm their subscription. And what about the person who signed up at the music festival? Later, while they’re reminiscing about the festival, they get an email asking if they want updates from the band. They click to confirm, and now they won’t miss out on any news about upcoming concerts or albums.

Double opt-in is a tad more effort, but it’s a solid way to know that the people on your list are truly interested and aren’t just passing by. Plus, it can help keep your email list clean and engaged, which is a win-win for you and your audience!

Maintaining a clean email list is a continuous process. People may change their email accounts or lose interest in your content. And if you keep sending emails to these accounts, there’s a higher chance of your emails being marked as spam. Campaign Refinery has an automatic list-cleaning tool that removes harmful emails before sending them out. So, your sender reputation won’t take a hit as you grow.

Is Opt-in Required for Email Marketing?

Opt-in is required in many counties because sending unsolicited marketing emails is against the law. For example, in the European Union, the General Data Protection Regulation (GDPR) mandates that you can’t send EU residents marketing emails without their consent. 

While the US doesn’t have a law that outright bans sending emails without consent, opting for opt-in email marketing is a wise move.

What’s more, come February 2024, Google and Yahoo are introducing new rules to fight spam. They’ll require bulk email senders to authenticate their emails using established best practices, like DMARC, SPF, and DKIM. They’re doing this to cut down on unwanted emails. So, if you’re planning to do any form of email marketing, you’ll need to obtain consent.

What is Opt-out in Email Marketing?

Opt-out in email marketing allows people to express that they don’t want to receive your emails anymore. 

Every marketing email you send out has to have this option, such as a button or a link, usually at the bottom, that says “unsubscribe.” When someone clicks on it, you should take them off your list and redirect them to a page that confirms their choice. 

Removing people from your list might seem like you’re just shrinking your audience, but it’s actually a smart move. A cleaner list means you’re not wasting time and resources sending messages to people who aren’t interested. You’ll have a lower bounce rate, and your email marketing efforts will be more efficient. 

Plus, letting people opt out isn’t just a best practice. According to the CAN-SPAM Act in the US, it’s a legal requirement.

How To Get the Most Out of Your Opt-in Email Marketing + Opt-in Form Examples

When inviting people to opt-in to your emails, a few best practices can go a long way to make sure you attract the right crowd and set the stage for a more engaging relationship. 

---

1. Let Them Know What’s Coming

When a person is considering whether to give you their email address, they’ll want to know what they’re signing up for. So, on the opt-in form, describe what type of emails they’ll receive and how often they’ll hear from you. For instance, you could say, “Sign up to receive our weekly blog updates and a monthly newsletter with exclusive tips!”

---

2. Make Opting-In Simple

A straightforward opt-in process encourages more people to sign up. Here are a few pointers:

• Keep it simple: Don’t ask for too much information upfront; an email address and maybe a first name is a good start.
• Well-timed pop-up: Have a subtle pop-up with the opt-in form appear at the right time, like after they’ve been on your page for a minute or two or when they’re about to leave.
• Easy to find form: If you don’t want to use pop-ups, make sure the opt-in form is easy to find and out of the way so it doesn’t interrupt your site’s UX — for example, a sticky footer or a sidebar. 

Check out this example from the Marketmilk blog. It’s direct, brief, and only asks for your email address.

3. Tempt Them With a Treat

Who doesn’t love a good freebie? Offering an incentive, aka a lead magnet, like a free ebook, a discount, or exclusive access can encourage people to sign up and grow your email list. You can even get creative and inject some fun into the sign-up process by creating a quiz or puzzle. But make sure your offer aligns with your audience’s interests and needs. 

Here’s a playful example by Sorted, the wealth guidance service sponsored by the government of New Zealand.

4. Set Clear Terms with Lead Magnets

When offering a lead magnet, let your users know they’ll also be getting your marketing emails. 

If it makes sense for your business, you could give them an option to opt-out of the marketing emails and just grab the freebie. This way, you respect their choice and keep a more focused list of subscribers.

The sustainable clothing brand Tentree does a great job of letting people know what they’re signing up for.

5. Implement Double Opt-In

We’ve already talked about the benefits of double opt-in. When creating your opt-in process, include a double opt-in system to ensure your subscribers genuinely want to engage with your content. 

Keep the design simple and clutter-free. Make sure to explain why your new subscribers have to confirm their email addresses. You can even include another incentive here to thank people for their effort. 

Here’s an example to inspire you. It’s the confirmation email sent by an independent SEO coach for a free webinar.

Explicit vs. Implicit Consent

When you’re doing email marketing, it matters how you get people to give you their email addresses. Explicit consent is when someone clearly says they want to get your marketing emails. They fill out an opt-in form or tick a box that says, “Yes, send me promotional emails.”

On the other hand, implicit consent is when someone gives you their email address but doesn’t specifically say they want to receive marketing emails from you. For example, they might provide their email to make a purchase or create an account on your website. 

Here’s a quick comparison to highlight the differences: 

	Implicit Consent	Explicit Consent
Clarity	Not so clear because they didn’t agree to receive marketing emails.	Clear because they actively agreed to receive marketing emails.
Engagement	Likely less because they might not be interested in marketing emails.	Likely more because they showed interest in receiving marketing emails.
Compliance	Might not comply with stricter email marketing laws and regulations.	More likely to comply with email marketing laws and regulations.
Risk of Spam	Higher chance of being marked as spam.	Lower chance of being marked as spam.
