NeverBounce

Verify email addresses in real time before sending, so your outreach lands — not bounces.

​
What Your Workers Can Do

Workers can pass email addresses to NeverBounce and get back a verification result before using them in outreach or storing them in your CRM. This keeps your sender reputation clean and your lists accurate. Popular use cases:
  • Verify a single email address before reaching out
  • Clean a batch of leads before an outreach campaign
  • Flag undeliverable addresses in an existing contact list
  • Enrich lead data with a “valid / invalid / risky” email status

​
Authentication

Type: API Key Go to NeverBounce → Dashboard → API Keys, create a key, and add it to your worker’s vault.

​
Example Workflows

Verify before sending 
"Before we send the proposal to john.smith@acmecorp.com, run it through NeverBounce and confirm the address is valid"
Clean a lead list 
"Here's a CSV of 500 leads. Run each email through NeverBounce and return a new CSV with a 'status' column showing valid, invalid, or risky."
Filter a prospecting output 
"Take the Apollo leads you just found and verify their email addresses with NeverBounce — only keep the ones marked valid"
