How to Find Emails in Airtable With the Tomba Extension

You can find emails in Airtable without leaving your base. The Tomba extension runs inside Airtable, reads the company and name columns you already have, and writes verified contact data into new fields. This guide shows how to install it, map your fields, run a table and keep your credit use under control.

Why find emails in Airtable?#

Many teams keep their prospect lists in Airtable because it is flexible. The usual problem is that the list has names and companies but no emails. Copying rows into another tool and back wastes time and creates version problems.

Running the lookup inside the base means:

• One source of truth. Results land next to the original record.
• Repeatable runs. You can rerun a view when new rows arrive.
• Less handling of exports. No CSV round trips.

What does the Tomba Airtable extension do?#

Tomba for Airtable finds, verifies and enriches contact data inside your tables. It includes 17 tools, among them Domain Search, Email Finder, Email Verifier, Phone Finder and Validator, Email Enrichment, Company Enrichment, Reveal, Technology and LinkedIn Finder.

Tools run on a table or view, up to 1,000 records at a time, with progress and time left shown. If your plan's rate limit is reached, the extension waits and carries on.

How do you install it and connect your account?#

1. Add the extension from the Airtable Marketplace to your base. Airtable's Free plan does not include extensions, so you need a plan that does.
2. Paste your Tomba API key and secret from app.tomba.io/api. The page says they stay in your browser.
3. Choose a table and a view.
4. Use Auto-map to match your fields, then check the cost shown and confirm the run.

Each team member connects their own key, and it is not saved in the base. Users need permission to edit the table and to add fields or tables.

How to find emails in Airtable: a step-by-step run#

Say you have a table with first name, last name and company domain.

1. Create a view that only shows rows you want to process, for example rows where the email is empty.
2. Open the Tomba extension and pick Email Finder.
3. Map first name, last name and domain with Auto-map.
4. Review the cost estimate, then confirm.
5. Keep the extension open until the run ends. If you close it, the run stops.
6. Read the status field. Each tool adds one, with "Found", "Not found" or "Error".

Records marked Found or Not found are skipped when you run again. Errored records are retried, so a second pass picks up only what failed.

Where do the results go?#

Answers are written to new fields or a new table, not into your existing fields. If a result would overwrite a field, the confirmation warns you first. A few examples of what each tool adds:

What does it cost?#

Credits depend on the tool. The Free plan includes 25 search credits a month, with no card required. Search and verification credits are separate balances.

• Domain Search: 1 search credit per 10 results requested, charged only when an address is found.
• Email Finder and Email Enrichment: 1 search credit each.
• Email Verifier: 1 verification credit.
• Phone Finder: 5 search credits, or 1 when the row has a domain. Charged only when a number is found.
• Reveal: 1 search credit per page of up to 50 companies.
• Technology: free, but needs a search balance above 0.

Lookups that find nothing are not charged. See Tomba pricing for plans.

Plan around the rate limits#

Rate limits depend on your plan. For the email finder, the page lists the Free plan at 1 request per second and 5 per day, and Pro at 8 per second and 4,000 per day. If you have a large table on a small plan, split the work into several days, or upgrade first.

Best practices when you find emails in Airtable#

• Verify what you find. Run the Email Verifier on the new addresses before you send. A found address is not always a deliverable one.
• Work in views. Limit each run to rows that need data so you do not spend credits on finished rows.
• Test with 10 rows first. Check the output and the cost before you run 1,000.
• Keep a status column. It lets you filter for Not found and decide on another route.
• Check the rules. If you email people in the EU or UK, review GDPR and local marketing rules before you send.

For very large lists, bulk tasks may suit you better than a base. If you prefer to build your own flow, the Tomba API and the Zapier integration offer other routes.

Frequently asked questions#

Do I need to code?#

No. The extension is point and click. You map fields and press run.

Will it overwrite my existing data?#

No. Results go to new fields or a new table, and the confirmation warns you if a result would overwrite a field.

What happens if I close the extension mid-run?#

The run stops. Records already done are skipped when you run again.

Is there a free option?#

Yes. The Free plan includes 25 search credits a month, but you also need an Airtable plan that supports extensions.

Start with one view#

Pick a small view, run the Tomba Email Finder on it, and check the results before you scale up.
