EmailOctopus provides a range of options for customisable sign up forms for all your lists. You can use these to collect subscribers and grow your lists. You'll find these in the 'Forms' section of the dropdown after you have selected 'Options' to the right of your list:
You have the option to create a 'Hosted' or an 'Embedded' form for your website. If you have a WordPress website, you can even create a form using our official WordPress plugin.
We also have a number of integrations with third-party sign up form creators that you can choose from.
