Original source drill-down 1 and Original source drill-down 2 are two analytics properties included on every contact record. Older HubSpot accounts may have the properties Original source data 1 and Original source data 2 instead, which contain the same information.
These drill-downs provide more insight on their original source (i.e., the contact's first visit or interaction with your business). Their values vary depending on the Original source property.
When viewing the Original source drill-down 2 property on a record, some values will appear with an information icon to show the internal value. 
Drill-down property values that don't show an information icon will display the internal value, for example addMessageUser. These internal values should be used when filtering contacts by their Original source drill-down properties.
Below are the general drill-down categories and values by Original source:
| Original source | Original source drill-down 1 | Original source drill-down 2 |
| Organic search | Search term (if available) | Search engine site |
| Referrals | Referring website domain | Referring website URL |
| Organic social | Social media site | Campaign name |
| Email marketing | Campaign name | HubSpot email name |
| Paid search | Campaign name | Search term (if available) |
| Paid social | Social media site | Campaign name |
| Direct traffic | Entrance URL | N/A |
| Other campaigns | Campaign name | Source / Medium |
| Offline sources | Offline channel/tool/platform. Examples include: IMPORT, SALES, API, BATCH_UPDATE, CONTACTS_WEB, MOBILE_IOS, SALESFORCE, BOT, CONVERSATIONS, EXTENSION |
Specific offline medium (e.g., BCC_TO_CRM, business-card-scanner, CRM_UI, salesforce-createdby, addMessageUser) |
- addMessageUser: the record was likely created by a non-bot chat conversation.
- CRM_UI: the record was created in HubSpot manually.
- SIDEKICK: the record was likely created by the HubSpot Sales integration.
- Email integration: the record was likely created by the HubSpot Sales integration or another email integration that is connected to HubSpot.
- BCC_to_CRM: the record was likely created through logging an email with the BCC or forwarding address.
