Bulk Emails Enrichment
What this tool does
Bulk Email Enrichment identifies verified work email addresses for a list of contacts based on their first name, last name, and company domain.
This tool is designed for:
Sales prospecting
CRM enrichment and cleaning
RevOps workflows
List building and outbound preparation
The process runs asynchronously in the background. Once started, you do not need to keep the page open. You can safely leave and return later to download results.
Only work (business) email addresses are searched.
What you need in your file

How enrichment works (waterfall logic)
What Is Waterfall Enrichment?
Tabula uses a waterfall enrichment system.
For each contact:
Provider A is queried first
If no verified email is found, Provider B is queried
If still not found, additional providers are queried sequentially
The process stops immediately upon finding a valid email.
Why This Matters
Higher overall match rate
Broader provider coverage
No duplicate charging
Only one credit is used per successfully found email
If no provider finds an email, no credit is consumed.
Credit usage and estimated cost
How Credits Work
1 successfully found email = 1 credit
No credit is used if no email is found
Failed lookups do not consume credits
Estimated Cost
Before starting enrichment, you will see:
Number of rows to enrich
Maximum credits that could be used (assuming 100% match rate)
Your current credit balance
The maximum credit estimate assumes that every row returns a valid email address. Actual credit usage is often lower.
You will never be charged more than the number of emails successfully found.
What happens after you click “Start Enrichment”
Once enrichment begins:
Processing runs in the background
You may close the page safely
The job continues asynchronously
Processing Time
Processing time depends on your file size and the provider's response time.
Small lists typically complete within minutes
Larger lists may take longer
Results
When processing is complete:
You can download a new CSV file from the Home page
Your original columns are preserved
A new column containing the found work email has been added
Rows without a found email remain in the file
Each row will indicate whether an email was found or not.
