Instafloss gives GetResponse real-time capabilities! Follow the instructions to start preventing bounces before they happen.

When you switch **Instafloss** on in the **Schedule** tab of your GetResponse integration, the **Instafloss instructions** dialog warns you that any existing callback will be overridden. To continue, tick **I understand the existing callback will be overridden** and click **Yes, I've completed the instructions. Turn on Instafloss**.

If you do not know or understand what the callback does, if it exists, we recommend contacting your IT administrator before turning on Instafloss. If you don't have an IT administrator and do not know or understand what the callback does, if it exists, we recommend you do not turn on Instafloss.

You can check if an existing callback exists by clicking [here](https://app.getresponse.com/callback). If the URL there doesn't start with "https\://webhooks.mailfloss.com" then this is an existing callback unrelated to mailfloss and will be overridden if Instafloss is turned on. Proceed with caution.
