The blocklist feature helps you maintain a list of prospects that should not be contacted through sequences. When a prospect is on your blocklist, they cannot be added to any sequence manually or through CSV imports.
- Prevent contacting prospects who have unsubscribed or requested not to be contacted
- Exclude competitors or specific companies from outreach
- Maintain compliance with do-not-contact requests
- Avoid duplicate outreach to prospects who have already declined
There are two ways to add prospects to your blocklist:
.1
- Click the "Upload CSV" button in the  Blocklist settings 
- Select your CSV file containing prospect information
- Map the CSV columns to the corresponding fields:
- Required: Email
- Optional: First Name, Last Name, Company, LinkedIn URL
- Review the preview to ensure correct mapping
- Click "Upload" to process the file
The blocklist interface shows:
- Prospect name
- Email address
- Company
- Date when they were added to the blocklist
- Total count of blocked prospects
You can search blocked prospects using the search bar, which looks through names, emails, and company names.
Below the blocked prospects list, you can view:
- History of all CSV uploads
- Status of each upload (Processing/Completed/Failed)
- Number of successfully processed rows
- Number of failed rows
Team admins and owners can remove prospects from the blocklist by:
.1Finding the prospect in the blocklist
.2Clicking the delete icon
.3Confirming the removal
- Once a prospect is blocklisted, they cannot be added to any sequence until removed from the blocklist
- Blocklist is team-wide - all team members share the same blocklist
- Only team admins and owners can upload CSVs or remove prospects from the blocklist
- At least one identifier (email, LinkedIn URL, or full name + company) is required to blocklist a prospect
- Regularly review and update your blocklist
- Use consistent naming and formatting in your CSV files
- Verify CSV mappings before uploading large files
