Why must I connect my inbox to HubSpot to send email from the CRM?

In order to send emails from your HubSpot CRM account, you must connect your inbox to HubSpot. If your inbox is hosted by Google Apps or Outlook 365, you can connect your inbox in just a few clicks using our native Gmail and Office 365 integrations or you can connect via IMAP.
With a connected inbox, you can access the following HubSpot features:
  • Automatically log email replies to contact timelines in HubSpot.
  • Send email from contact records in HubSpot using your own email servers. 
  • Send email attachments as files (not links) from HubSpot.
  • Take full advantage of HubSpot's sales tools (see above).

Automatically log email replies to contact timelines in HubSpot

When you send emails from your connected inbox, the replies to those emails will be automatically logged to the contact timeline, giving you better visibility into the communication with your leads and customers right in your HubSpot account without having to copy and paste or manually forward an email. In addition, any emails you send from the CRM will show up in your email client’s sent folder (Please note: this is not fully supported by all email clients yet).  

Send email from contact, company, and deal records in HubSpot using your own email servers

With a connected inbox, any emails you send from the CRM will be sent using your own email server IP address. This increases the likelihood that your emails will reach your lead’s inbox because those IPs belong to you or your company instead of shared among HubSpot users.

Additionally, you may have noticed that emails you sent from the HubSpot CRM without a connected inbox had the line sent via at the top of them. This line is added by email clients when an email is sent from a server that doesn’t match the domain in the From field (for example, sending on behalf of When you connect your inbox, emails you send from HubSpot will be sent through your email server, so your leads won’t see that line anymore.   

Send email attachments as files (not links) from HubSpot

With a connected inbox, you can send an email attachment from a contact, company, or deal record in HubSpot following these instructions, and your attachment will reach your contact's inbox as a file attachment, not as a link.
