Sequences are outreach campaigns that sales teams use to reach out to contacts over a planned period of time.

Use the Search for Outreach Emails endpoint to find emails that your team has created and sent as part of Apollo sequences.

To protect Apollo's performance for all users, this endpoint has a display limit of 50,000 records (100 records per page, up to 500 pages). Add more filters to narrow your search results as much as possible. This limitation does not restrict your access to Apollo's database; you just need to access the data in batches.
