Log email replies in the CRM

Last updated: January 31, 2024

Available with any of the following subscriptions, except where noted:

All products and plans

Replies to an email message sent from your connected personal email will automatically log to the contact's record in your CRM . This includes one-to-one emails sent from the record in the CRM or using the HubSpot Sales email extension or add-in. If you receive a reply to an email that was not previously logged, or a new email from a contact, you can log it in HubSpot manually using your forwarding address . Learn more about the requirements for replies to log and situations where replies will not log as expected. 

Please note: the maximum file size for logging attachments for outgoing and incoming emails is 50MB. This applies to replies sent to one-to-one emails and incoming emails sent to a team email in the conversations inbox

If your email server is running security software that scans attachments when receiving emails, HubSpot might not be able to log attachments that are included in email replies or incoming emails sent to your team email address. For example, if your Office 365 servers are running Advanced Threat Protection with Dynamic Delivery enabled, the attachments might not log. 

Requirements for a reply to log

Replies to emails will be logged automatically on the contact's timeline if you have connected your personal email and the following is true:


  • The original email was not sent to an email address or domain listed in your Never Log list.
  • The personal email address is still connected when the reply is received. 
  • The reply is sent to a personal email connected by the user who originally started the thread. 
  • The sender of the reply is an existing contact in HubSpot.

Email replies will log to the contact's record timeline in your CRM. You can then navigate to the recipient's contact record or one of the associated records to view the logged email.


If you connect a team email address to HubSpot, you can view, manage, and reply to incoming emails in the conversations inbox

Please note: if you connect a personal email account to HubSpot, sent emails from that account can only be logged using your forwarding address, which can then be reviewed on the associated record.

Replies not logging as expected

If your reply doesn't log as expected, learn more about some of the common reasons why this occurs. In some cases, if the reply didn't log, you can forward it to the record timeline in the CRM. 

New incoming emails

Incoming emails sent to your connected personal email will not log to HubSpot if they do not meet the requirements for logging

If a non-contact sends you a new email that is not part of an existing thread, this email will not log to HubSpot and a new contact record will not be created. When you reply to this email and select the Log checkbox or include the BCC address, your outgoing reply will log but the non-contact's original email will still not appear in HubSpot. Subsequent replies to this thread will log as long as your personal email is connected.

Emails sent from non-contacts or email aliases

If a reply comes from an email address that is not associated with an existing contact, the reply will not log. For example, if you send an email to, but the contact replies using, the reply will not log. You can forward the reply to the CRM using your forwarding address and then merge the two contact records.

Emails sent from a team email address

If an email thread starts with your team email in the conversations inbox, you cannot switch to using your personal connected email address mid-thread. The replies will not continue to log to HubSpot because this will create a new thread that HubSpot cannot detect.

Replies to emails after changing inbox providers

If you change inbox providers while you still have active threads using your previous email address, email replies will stop logging to HubSpot. In addition, if you're using sequences, contacts who are currently enrolled in a sequence will not be automatically unenrolled because HubSpot can no longer detect the replies. Reconnect your inbox using the correct provider to successfully log replies.

Connected personal email using wrong email provider

Make sure to connect your personal email using the correct email provider type. Your email provider is the service that enables you to send and receive emails. Common email providers include Gmail and Office 365.

Confirm which email provider your email address is hosted with, then follow the instructions to connect to HubSpot with that provider. If you're not sure which email provider your email address is hosted with, check with your IT administrator. If you do not connect using the correct provider, emails won't log.
