How Lead Enrichment Cuts Email Bounce Rates by 40%

Email bounce rates above 5% destroy your sender reputation. One of the fastest ways to fix this is enriching your contact list before sending.

The problem

Sales teams import leads from events, purchased lists, or web scraping. These sources are notoriously inaccurate — job titles change, people switch companies, and domains expire.

Sending to stale data means hard bounces, spam complaints, and eventually getting blocked by email providers.

The solution

Run your contact list through an enrichment API before any outreach:

1. Verify the person still works at the company — match name + domain
2. Get the current job title — filter out irrelevant contacts
3. Check confidence scores — only email contacts with high-confidence matches

Real results

Teams using pre-enrichment workflows typically see:

• 40% lower bounce rates — stale contacts are flagged before sending
• 25% higher reply rates — better targeting means more relevant outreach
• 3x faster list building — automated enrichment replaces manual research

Try it

Upload a batch of contacts to Leads Pro's batch endpoint and check the confidence scores. Any match below 70% confidence is worth a manual review before emailing.
