What is double opt-in?
Double opt-in is a newsletter subscription method that consists of two steps. After filling out the subscription form on the website, the user receives an email with a confirmation link. Only after clicking on this link is the user officially added to the subscriber list. This process ensures that only people who really want to receive messages are signed up, which increases the quality of the mailing list.

From a technical perspective, implementing double opt-in requires integrating a sign-up form with an email sending system that automatically generates and sends confirmation emails. This email contains a unique link that the user must click to confirm their sign-up. This requires an additional configuration step, both at the form level and in the newsletter program .
What is single opt-in?
Single opt-in in a newsletter means a form of subscription in which the user is added to the list of subscribers immediately after filling out the form, without the need for additional confirmation via e-mail. This process is simpler and faster for the user, which can lead to more subscriptions, but does not guarantee that all e-mail addresses are active and correct.
In terms of implementation, single opt-in only requires integrating the subscription form with the subscriber database. After filling out the form, the data is automatically saved and the subscriber starts receiving messages without the need for additional confirmations.
