Apollo.io
The value is the network, the data or the infrastructure. Keep paying.
A sales database with outreach attached: search a directory of companies and people, verify their email addresses, and run sequences at them from the same place.
The data is the product. Build the sending, and get the data legitimately. WHAT YOU CANNOT BUILD - The contact database. Do not scrape one; it is the fastest route to a blocked domain and a legal problem WHAT YOU CAN BUILD STACK - Postgres, a worker, SES or Postmark on a separate sending domain THE LIST - Import CSVs you have a lawful basis to mail - Store the source and the date for every contact, so you can answer where an address came from VERIFYING - Syntax, then MX lookup, then a paid verification API for anything that matters - Never send to an unverified list: one bad campaign costs months of reputation SEQUENCES - Ordered steps with day offsets, cancelled on any inbound reply - Hard cap per day per sending address, well under provider limits STAYING LEGAL - Unsubscribe honoured within one working day and stored forever - A suppression check before every single send Include the schema, the verification pipeline and the suppression check.
What you lose
- The database — hundreds of millions of contact records, continually re-verified, which is the entire product and cannot be built
- Email verification that keeps bounce rates low enough to protect a sending domain
- Intent and technology filters that make a list worth working
If you would rather not build
- Instantly or Lemlist for the sending half
- Hunter, for verification
- Your own CRM plus a bought list, if the list is properly sourced

18/100
Verdict no at 18. You cannot build a contact database, and scraping one is a bad idea for reasons that are legal as well as technical.
