Sendible allows you to add a piece of code to your website so that visitors to your site can opt in to your marketing materials and can be contacted via email and/or SMS. Users who sign up on your site will be automatically added to your Sendible Address Book and will be added to the group you have specified before generating the widget code.
Note: Contacts will only be saved to your Sendible Address Book if you've upgraded to one of our paid plans. You can, however, install and test the widget on your site before upgrading.
