Double opt-in

Double opt-in is a process that requires a subscriber to confirm their subscription before they can receive emails from you. It's a way to ensure that subscribers are actually interested in your content.

Single opt-in, conversely, does not require subscribers to confirm their subscription before they can receive emails from you. Single opt-in is allowed in certain use cases on Buttondown (for instance, if your subscribers are confirming their subscription on another platform such as Shopify or Stripe), but cold emails are not.

Buttondown does not allow you to disable double opt-in by default. This is for a few different reasons:

• It helps prevent spam and other nefarious activity, keeping your inbox clean and your subscribers happy.
• It helps ensure that subscribers are actually interested in your content.
• It helps us maintain compliance with GDPR and other privacy regulations.

If you have a special use case that requires you to disable double opt-in, you can do so by contacting us.
