This is a type of email subscription, by which a user should confirm their subscription to be added to a mailing list twice. It ensures both a valid and engaged mailing list. All subscription forms created with SendPulse use double opt-in confirmation.

The Confirmation Process Consists of 2 Steps

  1. Users submit their email address in the subscription form on the website and click "Join our mailing list."
  2. Then users receive a special confirmation email, where they need to confirm their wish to be added to your mailing list. It looks like this:Double opt-in subscription

Why is it essential to use a double opt-in subscription form?

With a double opt-in subscription, you will have a better quality mailing list because every email address in your list has double confirmation. Without a double opt-in subscription, you risk having bad email addresses in your list, because users could make spelling errors. Sometimes competitors may harm you by filling in the form with non-existent addresses that will damage your sender reputation. 

By using a double opt-in subscription, you can start email communication with your subscribers immediately because you send them a confirmation email. In this confirmation email, you can give subscribers more information about your brand, ask them to add your email to their address book, or provide new subscribers with a special offer. 

That's not rocket science since you don't even have to code. Choose a reliable email service with an intuitive subscription form builder.
