Vayne's Parallel Waterfall Runs
Unlike sequential waterfall providers, Vayne queries multiple data vendors simultaneously. Our algorithm cross-references all results to select the most accurate match — maximizing both coverage and quality.

Exactly What Data Comes Back
Email Enrichment Output

| John | Smith | acme.com | john.smith@acme.com ✓ |
| Sarah | Johnson | techcorp.io | s.johnson@techcorp.io ✓ |

| Bob Wilson | /in/bob-w | +44 20 7946 0X | UK | Europe/London |
For email enrichment, Vayne appends a single catch-all verified email per contact, and the ESP to enable ESP matching for your cold email campaigns. For phone enrichment, you get the mobile phone number, country of origin, and time zone — critical for US outbound teams coordinating calls across EST, CST, and PST.

Unique technology.
Not Just Waterfall — Parallel Waterfall
Most enrichment tools cascade through data vendors one by one: if the first source doesn't have your contact, they try the next. Vayne goes further.
We query all vendors simultaneously and let our accuracy algorithm determine the winning result. This means higher hit rates, fewer gaps, and better data quality — in the same amount of time.
- Multiple data vendors queried at the same time
- Accuracy algorithm selects the best result
- Higher hit rates than sequential waterfall
- Same speed as single-vendor lookups
Fast, Scalable, Built for B2B Teams
Industry-leading hit rate across all sectors
With US and EMEA benchmark
Buy only what you need, use at your pace
Whether you're enriching 50 or 50,000 contacts, Vayne processes your entire file and only bills you for successful matches. No wasted spend on contacts that can't be found.

Your Data Stays Yours
- No data resale — Your uploaded CSVs are processed and discarded. We don't build a database from your data.
- GDPR-aware processing — Contacts without a valid domain are skipped, not guessed.
- Credits returned for failures — If we can't find a contact, your credit is refunded. Zero risk.

Frequently Asked Questions
- What is email and phone enrichment?
-
Email and phone enrichment is the process of adding verified contact details (B2B email addresses and professional phone numbers) to an existing list of people. You provide a CSV with first name, last name, and company website — Vayne returns the verified email or phone number for each person.
- How does Vayne's waterfall enrichment work?
-
Unlike traditional waterfall providers that query vendors one after another, Vayne combines multiple data vendors in parallel simultaneously. Our algorithm then selects the most accurate result from all sources, maximizing both hit rate and data quality.
- What hit rate can I expect for email enrichment?
-
In typical use cases, Vayne achieves up to 90% email hit rate. Results can vary depending on your target, its location, and the quality of data you submit. For example Vayne will only process records with a website to maximize accuracy.
- Do I need a subscription to use enrichment credits?
-
No. Enrichment credits are purchased separately from scraping credits and are not a subscription. You buy only what you need, and credits are valid for 30 days. You are never charged for contacts we cannot find — unused credits are returned.
- What data do I need to enrich email addresses?
-
For email enrichment, you need first name, last name, and company website (or domain). If the company website is missing, Vayne will skip that row to avoid returning inaccurate results.
- What data do I need to enrich phone numbers?
-
For phone number enrichment, you need the LinkedIn profile URL. No company website is required for phone enrichment.
- What information does Vayne return for phone numbers?
-
For each phone number found, Vayne returns the phone number itself (typically a mobile number), the country of the number, and the time zone — which is especially useful for outbound calling teams prospecting in the US market.
- How does Vayne compare to Hunter, Apollo, or Lusha for email enrichment?
-
Vayne uses a parallel multi-vendor waterfall approach rather than relying on a single data source. This results in higher hit rates and better accuracy. And you never pay for contacts we cannot find.
- Is the enrichment feature available via API?
-
Yes. The email and phone enrichment feature is fully available through Vayne's API (documented as 'Contact Finder'). You can integrate it directly into automation workflows like N8N, or use it with any LLM by pasting the documentation.
- Is my data safe when using Vayne's enrichment?
-
Yes. Vayne processes your CSV securely and does not retain or resell your input data. The enrichment process is GDPR-aware: we only process records that include sufficient identifying information and return only publicly verifiable professional contact data.
