You already have the prospects. Names, companies, LinkedIn profiles, maybe company websites. The problem is the email column is empty. That’s exactly what email enrichment is for. Instead of searching for every email manually, upload your list to LeadsFriday and let our enrichment tools look for the missing work emails. With waterfall enrichment, the search doesn’t have to stop after checking one source.
What waterfall enrichment means
A single email data provider won’t have every email.
One provider might find 60% of your list. Another might have emails for some of the remaining 40%.
That’s the idea behind a waterfall.
Rather than depending on one source, the process can check multiple sources in sequence to improve coverage.
If an email is found, there’s no reason to keep searching for that record.
If it isn’t found, the next available source gets a chance.
The goal is simple: get more usable work emails from the same prospect list.
What you need before you start
The better your input data, the easier it is to match the right person.
Depending on the enrichment method, useful fields can include:
- First name
- Last name
- Full name
- Company name
- Company website or domain
- LinkedIn profile URL
- Job title
How the email waterfall works
You don’t necessarily need every field.
But if your spreadsheet contains only a name like John Smith with no company or profile information, matching the correct person becomes much harder.
Before uploading, take a minute to look at your CSV and make sure your columns are clean.
The idea is straightforward.
- 1 - You upload your prospect list.
- 2 - LeadsFriday uses the available information to look for a work email.
- 3 - If one source doesn’t produce a result, the workflow can continue through additional sources.
- 4 - Successful results are added to your data.
- 5 - You download the enriched file.
Why some emails aren’t found
You don’t need to upload the same spreadsheet to several different email tools yourself. That’s the work the waterfall is designed to reduce.
No enrichment service can find a reliable work email for every person. There are plenty of reasons.
Someone may have recently changed jobs.
The company may use an unusual email structure.
The business may have very little public information.
Or there simply may not be enough reliable data to return a result.
We’d rather leave a field blank than pretend we found something we didn’t.
No result is better than a guessed email that damages your campaign.
Upload your list to LeadsFriday
Open the appropriate email enrichment tool and upload your CSV.
Map the columns so LeadsFriday knows which fields contain the person’s name, company, domain, LinkedIn URL, or other available identifiers.
Review the pricing and submit your request.
The enrichment runs on our servers, so you don’t need to leave your browser open.
When it’s finished, your enriched file will be available from your order page.
What you get back
Your original data stays useful.
The enrichment results are added alongside the information you already provided, so you can connect each email back to the correct prospect.
Open the finished CSV and check the results.
You can then filter the file based on which records were successfully enriched and prepare those contacts for the next step.
Verify before sending
Finding an email and deciding it’s safe to send to aren’t exactly the same thing.
Email data changes. People leave companies. Domains change. Mailboxes disappear.
Before putting a large list into a cold email campaign, run the addresses through an email verifier.
That extra step helps you separate deliverable addresses from records that need more attention.
A clean workflow looks like this: build the prospect list - find work emails - verify the emails - prepare the campaign.
Try it with your own list
The best way to judge enrichment is with your own data.
Take a real prospect list, run a portion through LeadsFriday, and look at the results.
Don’t judge an email finder based only on a promised match rate.
Upload the people you actually want to reach and see what it can find.
