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

File Requirements

• File type: CSV

• The first row must contain column headers

How enrichment works (waterfall logic)

What Is Waterfall Enrichment?

Tabula uses a waterfall enrichment system.

For each contact:

1. Provider A is queried first

2. If no verified email is found, Provider B is queried

3. 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.
