Many countries have strict laws when it comes to email marketing which is a good thing. With Mailster you have a tool you can fulfill legal requirements from almost any country on the world. Some countries require you to add a confirmation checkbox where users have to agree that they sign up to your service.
In Mailster you can add a required checkbox via custom fields.
Create a new one like this one. You can also use anchor tags to add a link to your TOS.
Make sure the the checkbox is not checked by default.
Now add your custom fields to your form on the form edit page:
You can define an optional Error Message but make sure this field is “required”.
Now users cannot sign up without checking the checkbox on your sign up form.
