Question: Which of the following is NOT a way to increase your chances of landing in the primary inbox?
- Working on your sender reputation
- Ensuring proper set up of your email authentication
- Sending each of your emails to all the contacts in your CRM
- Being conscious of your delivery rate
Explanation
Sending every email to every contact ignores deliverability best practices because it can include unengaged or irrelevant recipients. HubSpot emphasizes that primary inbox placement is supported by a healthy sending reputation and recipient engagement. Proper email authentication helps mailbox providers verify that HubSpot is permitted to send on the domain’s behalf. Monitoring delivery performance is useful, but broad sending to the full CRM can increase spam complaints, unsubscribes, and poor engagement signals.
Why the other options are incorrect
Sender reputation directly affects inbox placement because mailbox providers evaluate sending behavior and recipient engagement.
Email authentication helps verify the sending domain and supports trust with inbox providers.
Delivery rate is a performance signal that helps identify sending or list-quality issues.
