Up until recently the IP addresses for Marketing Hub tools, Sales Hub tools, Service Hub tools, etc… were published I believe on

[Not receiving HubSpot system or notification emails](https://knowledge.hubspot.com/email/not-receiving-hubspot-system-or-notification-emails) .

Now there only seems to be IP addresses for the HubSpot email service published on a linked CSV.

We don’t want HubSpot to be blocked by our firewall when accessing our web site resources. Where is the correct IP address allowlist such that we can ensure this does not happen?

Thank you,

Alex.

Hi @alexangas,

There you go. “a list of all IPs that our emails from HubSpot may come from. Please consider allowlisting each of these to maximize your deliverability rate”

Thanks for your quick reply. That isn’t quite what we’re looking for - it’s the published list of IP addresses that HubSpot’s tooling uses to access our web site that we can no longer locate. Does that make sense?

The most recent list I can find is at the end of this post: [https://community.hubspot.com/t5/Tickets-Conversations/Create-a-user-with-an-email-alias-reflector/m-p/1210617/highlight/true#M8896](https://community.hubspot.com/t5/Tickets-Conversations/Create-a-user-with-an-email-alias-reflector/m-p/1210617/highlight/true#M8896)

However that is not an official list published by HubSpot.

@alexangas I’m not sure I’m following. If we’re referring to marketing emails, why would HubSpot “accessing website resources” play a role?
