Action Network uses SendGrid to deliver our emails, so whitelisting and whitelabeling happens automatically for large email providers such as Gmail, Hotmail, Outlook, Comcast, and the like. SendGrid is truly excellent, ensuring your emails end up in inboxes and not spam boxes and automatically managing any issues with these large email providers.
However, some organizations run their own email services. Because these services are so varied, distributed, and numerous, SendGrid can't handle relationships with them. However, administrators of these programs can whitelist the IP addresses we use to send email to ensure delivery.
If you run one of these programs or are working with someone to whitelist our emails, here are the IP addresses we use:
We are the only people who use these IP addresses -- all email going out over them is sent from Action Network -- so you can whitelist with confidence.
SPF and DKIM records
Though it's not strictly necessary, it's good practice to install an SPF record on the domain you send email from if you'd like. For more on DKIM and SPF records, click here.
