A signup form is used to join or register for something, like a service, a website, or a newsletter. It typically collects various details such as name, email, password, etc., for creating an account or gaining access to something.
On the other hand, a subscribe form is specifically for joining a mailing list or receiving updates. It typically collects an email address and sometimes additional information but focuses primarily on adding someone to a list to receive periodic information, newsletters, promotions, or updates.
MailBluster only supports subscribe forms from Forms where you can create, design and customize your subscribe form.
Please Note: MailBluster doesn’t support signup form. So you can’t create any signup form using MailBluster.
