When a contact subscribes through a form or a landing page, you can manage the subscription in two ways: single opt-in or double opt-in. It is a simple choice, but it directly impacts contact quality and the effectiveness of your communications.
In this article, we look at the differences between the two options and when it makes sense to use one or the other.
In magnews, the subscription mode is set through a service page.
If you want a complete overview, explore what service pages are and how they work.
If you need to create one, follow the step-by-step guide to creating a service page.
Single opt-in
With single opt-in, subscription happens in a single step: the contact fills out the form and is immediately registered as subscribed in the database, with no further confirmation.
This approach makes the subscription faster and more straightforward, as it does not introduce intermediate steps. It helps reduce friction and increase the number of subscriptions.
On the other hand, since there is no verification, it is easier to collect contacts entered by mistake, invalid email addresses or low-intent subscriptions. This can result in lower-quality contacts, a higher risk of spam complaints, and a negative impact on deliverability.
To reduce these risks, you can add a verification system such as reCAPTCHA to the subscription form. This helps limit automated or invalid entries while keeping a simple, single-step flow.
In summary, single opt-in is suitable when working with simple forms or low-risk contexts and when your main goal is to maximize the number of new contacts, prioritizing quantity over control on quality.
Double opt-in
With double opt-in, subscription is completed in two steps: first the contact fills out the form, then confirms the request via the link received by email. Until that moment, the contact remains in the “Unconfirmed” status and is only registered as subscribed after clicking the link.
This mechanism significantly reduces errors and unintended sign-ups, preventing non-existent or incorrectly typed email addresses from entering your database, and allows you to collect stronger consent, also from a GDPR perspective.
The result is a generally more reliable contact base, with valid email addresses and better results over time, including deliverability: by sending communications to real addresses, you reduce bounces and the risk of your sending domain being penalized or flagged as spam by providers.
On the downside, it introduces an additional step: some users may not complete the confirmation, and therefore will not enter the database.
Double opt-in is the best choice when data quality and consent traceability are critical, for example with sensitive databases or in contexts where you need stricter control over subscriptions.
This approach also helps protect sender reputation and communication performance.
How it works in magnews
When you create a subscription service page, you can start from two ready-made templates: one for single opt-in and one for double opt-in.
In the single opt-in template:
- The form button is already configured with the subscription action
- When submitted, the contact is saved and immediately subscribed
You start from a ready-to-use configuration that you can modify as needed.
In the double opt-in template:
- The form button sends a subscription confirmation email
- The confirmation message is already set up and active. You can customize it, replace it with your own, or use it as is.
How subscription is completed with double opt-in
Here is what happens step by step:
- The contact fills out the subscription form
- They are added to the database as “Unconfirmed”
- They receive the confirmation email
- They click the link in the message
- They see the final confirmation page
- They are registered as subscribed
If you want to customize the final message, keep in mind that the link in the email points to the subscription confirmation page, not the subscription page.
For this reason, you should not modify the subscription page, but the confirmation page.
In most cases, you will already find it in the database. If not, you can create one or link an existing page.
So, should you choose single or double opt-in?
There is no right or wrong choice: it depends on the strategy you want to adopt.
- Single opt-in: more subscriptions and a faster process
- Double opt-in: fewer sign-ups, but more reliable contacts, with valid email addresses and better deliverability results
If you are just getting started or working with high volumes, you can start with single opt-in.
If you want to build a more solid contact base over time, double opt-in is the safer choice.
