If you are sending marketing emails, you run the risk of occasionally having your organization's—or your target organizations'—firewall outright reject delivery of your email. Firewalls are set to monitor for and protect against abusive or fraudulent emails, such as spam and phishing. Marketing emails can and do run afoul of those firewalls despite their non-abusive intention.
When sending marketing emails through Feathr, you are using email servers Feathr contracts with through AWS (Amazon Web Services), which may be unknown to your organization's—or your marketing prospect organizations'—firewalls.
This article will guide you through the steps to request whitelisting of your Feathr email IP ranges to avoid deliverability problems caused by firewalls.
How to Make the Request
If your own staff is not receiving your emails:
You will need to request that your own IT or web department add the IP address ranges listed below to your organization's firewall whitelist. You may already have a contact in your IT department to run it by, but if not, start with a version of the sample request below.
If your target organizations are not receiving your emails:
Since you as a marketer have no direct control over the firewall settings of the organizations you're emailing, you will need to contact the organizations to request your email server's IP ranges be "whitelisted" on their firewall settings. It is usually the webmaster, web team, web administrator, or IT manager at these organizations who has control over decisions related to firewall settings.
Some organizations will already have a process in place to request IP whitelisting, and can supply you with an official request form. Some will just require you to have a conversation with an appointed person on their side. In either case, it is unlikely that yours will be the first IP whitelist request they've received. They will know what you're talking about when you begin the conversation.
Delivery IP Ranges to Request
The following are the actual IP address ranges you will need to request be whitelisted. Keep them formatted as you see here by copying and pasting them directly in your request.

- ip4:199.127.232.0/22

Sample Request Copy
Dear [Organization],
My name is [name] and I am a [title] at [your organization]. It has come to my attention that emails from our organization to yours are being blocked by your firewall, even though recipients at [your organization] have opted in to receive communication from [our organization]. I would like to request that our email IP ranges be whitelisted so that employees at [your organization] can receive the information and communication they requested from us. Do you have a formal process or form to make this request? These are the IP ranges I'm requesting to whitelist:
