I’m not sure how this works, but I’ll just throw it out here.
I’m new to Hubspot, I have invited two co-workers, and no matter what I do, one of my co-workers does not get the invite. Has anyone run into this?
Hi @WWR,
Welcome to HubSpot and the Community!
Thank you for reaching out 
Would you mind confirming all the steps detailed in the following article have been followed? They should help: Not receiving HubSpot system or notification emails
Can you please let us know if these steps help? Thank you!
Best,
Kristen
I’m getting lost in all the details. I’m just taking the first step with this software, setting up myself and two other user. I haven’t even started working on it, and I’ve already spent 4 hours trying to get past sending an invite. Wow. Maybe this one isn’t for me???
Hi @WWR,
Thank you for your feedback. I apologize for any business impact this may have caused.
In order to look into this further, I first have to confirm if you have gone through the troubleshooting steps in the linked article including allowlisting.
Can you confirm that your colleagues have allowlisted the HubSpot email addresses and IP Addresses and are still not receiving the invite emails?
Thank you,
Kristen
