Email Opt-in: How to Implement Double Opt-In and Simplify Email Marketing Consent Collection with iubenda’s Newsletter Opt-in Booster

preview

When setting up an email marketing strategy, it’s crucial to grasp the principles of email marketing compliance.

Obtaining explicit consent or permission from users to receive promotional emails, newsletters, or marketing emails from a particular sender ensures that recipients have willingly subscribed to receive content and contribute to a healthy sender reputation.

Email “Opt-in” generally refers to a scenario where users manually fill out a form or click a checkbox on a form to confirm their permission to receive emails. Once this is done, they’re signed up and will start getting emails.

With Double Opt-in, it’s a bit different. After users fill out the form, they get an email asking them to confirm their subscription. They need to click a link in that email to verify their email address and officially join the list. Only then will they start getting emails.

While there’s no strict legal requirement to have a double opt-in process, yet, it’s considered best practice in many countries, especially Germany and in the EU in general. This method helps to ensure the email address receiving the communication actually belongs to the person giving the consent and hereby further ensures avoiding high unsubscribe rates.

Email opt-in is crucial for several reasons. Firstly, it ensures that recipients are genuinely interested in the content being sent to them, leading to higher open and click-through rates. Secondly, it helps businesses comply with regulations such as GDPR (General Data Protection Regulation) and CAN-SPAM Act, reducing the risk of legal repercussions. Additionally, opt-in emails contribute to building a more targeted and engaged subscriber base, resulting in more effective marketing campaigns and better ROI (Return on Investment).

Integration with email marketing tools

When a new subscriber signs up through the Newsletter Opt-in Booster, their information is captured within the Consent Database. However, to ensure they receive future communications, their consent status needs to be manually exported from the Consent Database and imported into your email marketing tool of choice. This ensures seamless communication with your subscribers.

Subscription process for end users

  • Your site visitors will interact with the sign-up form on your website to subscribe to your newsletter.
  • They’ll provide their consent by filling out the form and confirming their subscription.

⚠️ Important: Double-Opt-In Confirmation

When someone uses the sign-up form to sign up for your newsletter, they’re not done yet. Next, they’ll get an email asking them to confirm they really want to subscribe. To actually become a subscriber, they need to click on a link in that email. This is an important step, because just putting their email address into the widget isn’t enough to finish signing up. This double-check ensures compliance with double opt-in best practices.

Subscriptions dashboard

Once you activate and embed the Newsletter Opt-in Booster, you get access to a subscriptions dashboard (Newsletter Subscriptions), where you can manage and monitor user consent for newsletter subscriptions effectively.

The Dashboard provides several functionalities, including filtering by date range, sorting by type, and exporting subscription data in CSV format. You can use this file to easily upload the data to your email marketing tool. This integration not only provides valuable insights but also enhances coordination with other systems, optimizing your targeted marketing efforts.

FAQs

What are the different types of opt-in methods?

There are two main types of opt-in methods:

  1. Single Opt-In: In this method, individuals provide their email addresses and other necessary information directly into an opt-in form on a website or through another channel. Once submitted, they are immediately added to the mailing list without requiring any further action. While single opt-in is quick and convenient for users, it may lead to a higher risk of fake or mistyped email addresses being added to the list.
  2. Double Opt-In: With double opt-in, individuals go through an additional step to confirm their subscription. After submitting their email address through an opt-in form, they receive a confirmation email asking them to verify their subscription by clicking on a link or button. Only after this confirmation step is completed are they added to the mailing list. Double opt-in helps ensure the accuracy of the subscriber list, reduces the risk of spam complaints, and demonstrates a higher level of engagement from subscribers.
