Double opt-in

What is double opt-in?

Double opt-in (also known as confirmed opt-in) is a two-step sign-up process for newsletters. When a visitor fills out the sign-up form, they first receive a confirmation email with a link. Only after they click the link are they subscribed to the newsletter. This verifies that the person actually owns the email address they provided.

Single opt-in vs. double opt-in

There are two methods for newsletter sign-up:

• Single opt-in: The user is subscribed immediately after entering their email and clicking “Subscribe.” Quick and easy, but leaves the door open to fake subscriptions and bots.
• Double opt-in: The user receives a confirmation email and must click a link to confirm. Slower, but results in a cleaner list with higher engagement.

Benefits of double opt-in

• Eliminates bots and spam: Automated sign-ups cannot verify the email address, and fake sign-ups are automatically blocked.
• Higher list quality: All subscribers are verified, engaged individuals with valid email addresses.
• Better deliverability: Fewer bounces and spam complaints result in a better delivery rate with email providers such as Gmail, Outlook, and Yahoo.
• GDPR documentation: You have stronger proof of consent, since the user has actively confirmed their subscription. This can be crucial in the event of a complaint.
• Higher engagement: A cleaner list typically results in better open and click-through rates, since all subscribers have confirmed their interest themselves.
• Protects your sender reputation: Email providers view senders with low bounce and spam rates favorably, which improves your future delivery rates.

Disadvantages of double opt-in

• Lost sign-ups: 10–30% of users forget or fail to click the confirmation link.
• Extra friction: An extra step can deter some potential subscribers, especially on mobile.
• Confirmation email in spam: The confirmation email may end up in the spam folder, so the user never sees it.
• Delayed sign-up: It can take time from when the user signs up until they confirm—and during that time, their motivation may wane.

Double opt-in in Shoporama

Shoporama has built-in support for double opt-in for newsletters. You can enable it under “Newsletter” in the admin panel, where you can turn double opt-in on or off. When it’s enabled, the following happens:

1. The customer fills out the sign-up form in your online store (pop-up, footer, or dedicated form).
2. Shoporama generates a unique confirmation token and sends a confirmation email.
3. The customer clicks the confirmation link in the email.
4. The subscription is activated, and the customer will receive future newsletters.

You can customize the confirmation email using the theme’s email templates under mails/newsletter_confirm.html. Here, you can edit the subject line, text, and design to match your shop’s branding.

When should you use double opt-in?

Double opt-in is recommended as the default for most online stores. It results in a cleaner list, better deliverability, and stronger GDPR compliance. The only situation where single opt-in might make sense is if you have very low traffic and every sign-up is critical—but even then, the benefits of double opt-in typically outweigh the drawback of losing a few sign-ups.

Tips for Reducing Losses with Double Opt-In

• Clear message: Clearly tell the user that they need to check their inbox and confirm their subscription.
• Prompt delivery: The confirmation email should be sent immediately, while the user still remembers it.
• Good subject line: Use a clear subject line such as “Confirm your subscription to [store name]”—avoid making it look like spam.
• Simple email: The confirmation email should have one clear purpose: a large, visible confirmation link.
• Reminder about the spam folder: Mention on the sign-up page that the user should check their spam folder if the email doesn’t appear.
