Integrate your GetResponse account with your PayPal services account and maximize your conversion rate.
Add a GetResponse notification URL into the Instant Payment Notifications settings. Then create a BUY NOW button and add your campaign as a custom value in the third step during the button creation. And that’s it! Now, whenever the generated button or URL is clicked it will launch the PayPal transaction and in the same time add the contact into your GetResponse campaign, significantly minimizing the time and resources necessary for a subscriber to convert.
