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"
