Understand why contacts didn't receive marketing emails

After sending a marketing email from HubSpot, you can analyze its performance or check contact records to see which contacts received the email.  If an email is marked as delivered but the contact can't find it in their inbox, the issue is usually related to spam filtering, inbox placement, or email security settings.

This article explains why a delivered marketing email may not appear in a recipient's inbox. Learn more about reasons why a recipient wouldn't be sent a marketing email. 

See if a marketing email was delivered

If a recipient didn't receive a marketing email, you can check to see if the email was successfully delivered to their email server. 

1. In your HubSpot account, click More, then navigate to CRM > Contacts. If More doesn't appear in your account, navigate to CRM > Contacts directly.
2. Click the name of the contact. 
3. At the top of the contact record, click the Activities tab. 
4. Click the Filter by dropdown menu and select the checkbox next to Marketing emails. To expedite the process, clear the checkboxes next to each other activity type. 
5. Locate the marketing email the contact didn't receive and see if it was sent and delivered. Learn more about reasons why a contact wouldn't be sent a marketing email. 

Understand why delivered emails may not appear in a recipient's inbox 

There are two main reasons the contact may not see the marketing email in their inbox, even though it's marked as delivered: 

• The email has been sent to the recipient's spam or junk folder.
• The recipient's security filter quarantined the email and prevented it from being delivered to the recipient's inbox. 

In both cases, HubSpot's server will still receive a confirmation from the recipient's server that the email was accepted. Marketing emails to these recipients will still be identified as delivered in HubSpot. 

Resolve issues with recipients not receiving delivered emails

If recipients contact you to understand why your emails didn't reach their inbox, you can recommend the following: 

• Check their spam or junk folder. If previous emails from your organization are there, recipients should move them into the inbox.
• Review any filtering or forwarding rules that may have prevented the email from reaching the inbox.
• If using Gmail, check the Promotions tab. To receive future messages from your company in the Primary tab, move the emails they've received from you into that tab. 
• If the emails are not in the spam or junk folder, they should work with their IT team to determine if the email was quarantined. You should provide the recipient with the subject line, from address, recipient email address, and delivery date and timestamp of the email. 
• For recurring delivery issues, recipients should also: 
  • Add your From address to their email client address book. 
  • Open marketing emails they have successfully received from you and click links.

• • Request that their IT team add your sending IPs and email sending domain to an allowlist. 

Give recipients sending IP addresses to allowlist

Ask recipients to allowlist the IP addresses HubSpot uses to send marketing emails to help ensure your emails reach their inboxes.

To find the IP addresses HubSpot uses to send marketing emails from your account: 

1. In your HubSpot account, click More, then navigate to Marketing > Email. If More doesn't appear in your account, navigate to Marketing > Email directly.
2. In the top right, click the Email tools dropdown menu and select Manage allowlisting. 

3. In the dialog box, click Copy. This will copy all IP addresses to your clipboard. 
4. Provide the IT team of the recipient having trouble receiving your emails with the full list of IP addresses. Ensure the allowlist includes all listed individual IP addresses and ranges. 
5. Provide the IT team of the recipient with the email sending domain you use to send emails from HubSpot. If you haven't connected an email sending domain, they can add hubspotemail.net. 

Prevent future email deliverability issues

To help prevent future deliverability issues, it's recommended to follow these email deliverability best practices for senders: 

• Connect your email sending domain (not available in accounts only using HubSpot's free tools). 
• If you've connected an email sending domain, make sure DKIM, SPF records, and your DMARC policy are set up correctly. 
• If you've connected an email sending domain, make sure the from address you're using for your emails is hosted on the email sending domain. 
• Consider using fewer shortened links, as these can cause a higher rate of spam reports.
