How To Find Email Addresses In Google Sheets

Cold outreach is getting harder every year.

Average cold email reply rates have dropped to just 5.1% while 43% of salespeople say getting higher-quality data is their biggest prospecting challenge.

That combination creates a frustrating reality for revenue teams. Reps are sending more emails, doing more research, and spending more time building lists, yet results continue to decline.

A big reason is bad contact data.

If email addresses are invalid or outdated, campaigns never have an opportunity to do well.

But, there is a much quicker way of finding verified email addresses without having to switch between several tools. You can do it directly inside Google Sheets with Clearout Email Finder.

This guide will explain how to use Clearout's Email Finder to find email addresses in Google Sheets in a matter of clicks.

Why is your current email process costing you money?

If you are doing outbound, you have probably been through this before. You build a prospect list in Google Sheets. Then you jump to LinkedIn to find contacts. Open another tool to find emails. Open one more to cross-check them. Copy the results back into your spreadsheet.

As a result, email finding gets rushed. Guessed formats stay on the list. Campaigns go out anyway. Then the connection rates stay flat and nobody can explain why.

That is why having email finding directly inside Google Sheets changes the workflow entirely. You stay in the same sheet, get results instantly, and move from prospecting to outreach without the extra back and forth.

How to install Clearout Google Sheets add-on?

Google Sheets Extensions menu showing Add-ons.

There are just a few steps to start finding email address through Clearout for Sheets.

First, go to any Google Sheet and head over to Extensions → Add-ons → Get add-ons.
This will open the Google Workspace Marketplace. Search for Clearout for Sheets and open the listing.
Next, click Install and approve the permissions.
Once the installation is complete, go back to your Google Sheet and open Extensions → Clearout for Sheets → Launch.

Clearout opens in a sidebar, so you can find emails in bulk on Google Sheets and manage your data without constantly switching between tabs and tools.

Connecting your Clearout account

Installing Clearout for Sheets extension.

Before you start to find email addresses in Google Sheets, you will need to connect your Clearout account.

The first time you open the sidebar, Clearout will ask for your API key.

Open your Clearout dashboard, click on Developer's section, and create an API key. Then, copy the key into the clipboard and then paste it into the add-on.

Clearout will remember the API key for your account when connected, so that you don't have to input it again each time.

Step-by-step guide: Find email addresses in Google Sheets

Use Clearout Email Finder for Google Sheets when building new prospecting lists. You have target companies and prospect names from LinkedIn, website research, or databases, but need actual email addresses.

Step 1: Structure your data before starting

Google sheet with first, last, company, and domain as columns.

Create columns in this exact order to find emails on Google Sheets:

First Name
Last Name
Company
Domain

Step 2: Install and authenticate Clearout

Email Finder opened from Clearout for Sheets.

Open Extensions → Clearout for Sheets → Launch.

Once the sidebar appears, hit the API token link and copy your API key from the Clearout dashboard.

Just copy and paste it to the sidebar and you're good to go.

It only requires under 30 seconds to setup and will only need to be done once.

Step 3: Auto-mapping

Clearout automatically extracts your sheet's information, such as names, company names, and domains.

When you are looking up an email address for the similar names, it will become much easier if you include their company domain.

Step 4: Use filter views to target specific segments

Clearout Email Finder advanced settings.

Before running the Google Sheets email finder, simply apply a filter to get only the rows you want to work on. Only the checked rows are processed by Clearout.

This allows you more flexibility in how you use the credits and helps you work for more focused batches.

Step 5: Click "Find email addresses" and watch real-time updates

Find email address button in the Clearout Email Finder.

Once you click “Find Email Addresses”, Clearout gets to work right away.

As emails are found, a few new columns will be added:

Clearout Finder Status: It shows whether the email address was successfully discovered or not.
Clearout Finder Reason: Shows the reason if the email address is not found.
Clearout Finder Domain: Shows the domain associated with the found email address
Confidence Score: A number from 0 to 100 that helps you understand how likely the email address is valid and reachable. It's colour-coded to help you find matches of high confidence score easily.

Step 6: Filter by confidence score and prioritize high-quality leads

Output fields after finding email address from Clearout Email Finder.

After finding completes, sort by Clearout Finder Confidence Score descending. The colour coding helps you prioritise at a glance:

Confidence 90 and above shows in green: certainty level, email is almost definitely correct, used immediately for outreach.
Confidence 80 to 89 shows in blue: very confident, good for cold email campaigns.
Confidence below 80 shows in grey: consider verifying with Clearout Email Verifier before sending.

Step 7: Verify low-confidence emails before sending

Found emails with confidence scores below 80 should not be sent without further verification. Filter those rows and run Clearout Email Verifier to confirm they actually exist. This two-step approach of finding and then verifying gives you the highest possible accuracy of 99.73%.

Common mistakes that cost teams thousands

Using confidence scores incorrectly: Sending to emails with a confidence score below 80 without verifying first is one of the most common and costly mistakes in outbound. For cold outreach use 80 or above only. For lower-priority prospecting, 70 or above is acceptable.
Forgetting to refresh old lists: Lists older than 6 months degrade 15 to 20% annually. Contacts change jobs. Domains change. Re-run Email Finder on stale prospect lists before any new campaign cycle.
Skipping segmentation on confidence tiers: Not all found emails are equal. Treating a 91-score contact the same as a 74-score contact inflates your effective bounce risk without showing up obviously in any single metric. Always route by confidence tier before sending.
Mixing found and unverified contacts: If the confidence score of the found email addresses is below 80, then verify them with Clearout Email Verifier.

How much better are your results? Real numbers

Teams that implement Google Sheets email finder see measurable improvements fast:

14 hours saved per month on email data work per rep
3.2x higher email open rates from outreach to verified, found contacts
23% more new contacts added per prospecting cycle
SDR research time drops from 3.5 hours per week to under 40 minutes

Real-world use case: How a B2B sales team uses the Clearout Email Finder for Google Sheets?

The result a B2B sales team got after using Clearout Email Finder.

A B2B SaaS business offers a workflow automation software solution to ops leaders in mid-market manufacturing firms (200 – 2,000 employees). The revenue team is 15 SDRs, 1 sales operations manager and is on Salesforce as their CRM, with outreach being their sequencing tool.

What did their workflow look like before Clearout?

Before Clearout, the workflow looked something like this:

Export a list of target accounts into Google Sheets.
Open LinkedIn profiles one by one to find contact details.
Check company websites and manually guess the likely email format for each person.
Spend the rest of the session copy-pasting guesses into a separate checker and waiting.
Import the final cleaned list into the outreach platform.

What changed after installing Clearout's Email Finder for Google Sheets?

Account research stays in the sheet. SDRs populate First Name, Last Name, and Domain from LinkedIn Sales Navigator.
Email Finder runs on filtered segments using the Segment Processing feature.
Confidence score determines routing. The sales ops manager has set a team rule: any email with a confidence score of 90 or above goes directly into the Outreach import queue.
The outreach import happens from the clean sheet.

Results after 90 days

The bounce rate dropped from 18% to 2.4%. It was a result of routing only 90+ confidence score addresses into sequences and verifying the remaining separately before any send.
SDR time spent on email research dropped from 3.5 hours per week to 40 minutes.
Open rates on the Outreach sequences increased from 22% to 41%.
The team added 23% more new contacts.
