Higher Education leads that list. However, the long tail matters just as much. Adoption reaches 47 industries in total. So you can narrow the list to the segment you sell into.

The matched companies sit in 33 countries. These lead the sample:
- United States 35

How to find websites that use Otter Blocks
Start with the table above. Then follow these four steps to turn it into an outreach list:
- Filter the sample. Narrow by industry or country until the rows match your ideal customer profile.
- Export the domains. Share the page to unlock the CSV, or sign in for the full dataset.
- Find the people. Run each domain through Domain Search to pull every work email behind it.
- Verify before you send. Pass the results through the Email Verifier so your bounce rate stays low.
Working at volume? Push the whole export through Bulk Tasks instead, or call the Domain Search API directly from your own stack.
