To send your newsletter subscribers from your website to iContact, you need to first create a page which includes the newsletter email opt-in module with the help of the Page Designer. In the Content tab select iContact as the Service Provider. This will make sure that your newsletter subscriber registrations are automatically sent to your selected service provider.
Log in to your iContact account, select your username from the top right corner, click on Settings and Billing, then on iContact Integrations. Go to the Create button, copy and paste the API App ID, Username and Password into the newsletter email opt-in module. Check more information here.
With iContact you can get a 30-day free trial with unlimited sending. More info here.
