Your IT team may need to whitelist domains and IP addresses so that HubSpot emails get delivered internally
When HubSpot emails bounce internally there are two things you should do to ensure emails get delivered:
- Whitelist HubSpot domains and email addresses
- Whitelist IP addresses
What you need to know about whitelisting email addresses
Whitelisting an email address is the process of telling your email provider that a specific email address is "safe".
Many companies today have robust back-end restrictions on their email hosting which is designed to reduce spam and phishing emails from coming in to business emails. These restrictions generally include "generic" email addresses, things like noreply@ and notifications@.
When you get HubSpot, you want to work with your IT team to make changes to your whitelist/allowlist/safe sender list.
The following is a complete list of email addresses HubSpot uses for internal email notifications:
- noreply@hubspot.com
- noreply@notifications.hubspot.com
- noreply@notifications.transactional.hubspot.com
- success@hubspot.com
- hubspotreports@hubspot.com
- notifications@hubspot.com
- notifications@email.leadin.com
If you're using a free email provider such as Gmail, you can find whitelisting instructions in their help documentation.
Whitelist IP addresses
HubSpot has a robust online platform which offers in-app notifications, if your team is not receiving these notifications, whitelisting the HubSpot IP addresses will help.
HubSpot recommends adding your sending IP addresses and hubspotemail.net to your network-level allowlist.
Below are the IP addresses HubSpot uses:
