Hi Katy,
This most often happens when our initial email to that user is held by their email provider. This is not uncommon for an email provider to hold or review an email from a new sender to an inbox if it isn't part of the company whitelist. When this happens that user ends up on our email providers suppression list that blocks them getting email from Quick Base to avoid being considered Spam. The best way to get a resolution for that user is to reach out to the Care Team here at Quick Base and let them know the specific user email that is having issues. That way we can look on our end to see if it is being suppressed and retrigger those emails once they have been cleared. You can put in a case when signed into Quick Base by clicking on the question mark icon that appears in the upper right hand corner and selecting Manage Support Cases or directly
here.
To help avoid this from happening we do recommend that Admins make sure that the Quick Base email server ip addresses are whitelisted, as are the email addresses we use to end out content. You can find a knowledge base article we maintain with the current ip addresses and email addresses to whitelist
here.
