In Userled: Export your sequence prospects as CSV. It should look something like this, with the Outreach URL and Preview URL for the image thumbnail.
Name | First Name | Last Name | Company Name | Outreach URL | Outreach (preview) URL | |
Steve Smith | Smith@Example.io | Steve | Smith | Motor City Wash Works | https://explore.example.com/BvPlVChSM | https://us.assets.userled.io/7ff390a-9e2f-4250-80ef-00a317e35731/BvPlVChSM.png?ts=1764083374 |
Admin Settings (gear icon) > All Settings > Data Management > Objects, Fields, Stages.

Select the the relevant option, for Contacts or Accounts, and then navigate to the fields tab. For contacts the url is likely: https://app.apollo.io/#/settings/contacts/fields
Add these Exact fields (Single-line textโno spaces for reliability):
Field Name | Type | Maps To |
UserledLP | Single-line text | "Outreach URL" (landing page link) |
UserledThumbnail | Single-line text | "Outreach (preview) URL" (thumbnail PNG link) |
This now gives us a destination for the Outreach URL and the Preview URL thumbnail in Apollo.
Upload the CSV that you downloaded in step 1 from Userled. Import this to Apollo as Contacts or Accounts.

Once you've uploaded your file, Apollo will try to match the CSV headers to the fields in Apollo. We'll want to double-check that this is done correctly, especially for the last two columns, which are Outreach URL and Preview URL. Make sure these are mapped to the properties we set up earlier.

Hit Import once ready to add to Apollo.
We now have the Userled LP and Thumbnail in Apollo 
We can create a sequence that uses these custom fields to create a 1:1 email using the dedicated Userled page.
