Tomba Email Count

See how many contacts you can reach at any company before you spend a cent on outreach. Paste a list of domains and get the number of email addresses Tomba knows for each one, split into personal and generic addresses, by department and by seniority.

Pricing

$0.00312 per domain ($3.12 per 1,000). No subscription and no Tomba account needed.

You are only charged when Tomba returns a count:

What happens	Charged
A count is returned for the domain	Yes
A count of zero is returned for the domain	Yes
No count returned	No
Invalid domain or any other error	No
Temporary failure (it is retried automatically)	No
Result served from the cache	No

Every row shows charged and cached, so you always know what you paid for. To cap your spend, set Maximum cost per run in the run options: the Actor stops cleanly when the limit is reached.

Built for big lists

• No rate limit: up to 50 domains are processed at the same time
• Automatic retries: temporary failures are retried for you, and never billed
• Resumable: if a run is interrupted, it continues where it stopped without charging you again
• Cache: repeat lookups within 24 hours are free

Real-time API

Need the count instantly inside your own app? This Actor also runs as a real-time API (Apify Standby mode): no run to start, no dataset to fetch, just an HTTP request that returns JSON in seconds. Pricing is the same.

curl "https://<your-standby-url>/?domain=stripe.com&domain=tomba.io" \
  -H "Authorization: Bearer <YOUR_APIFY_TOKEN>"

You can also POST the same JSON input as a normal run:

curl -X POST "https://<your-standby-url>/" \
  -H "Authorization: Bearer <YOUR_APIFY_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"domains": ["stripe.com", "tomba.io"]}'

The response is { "items": [...] }, with the same rows as the dataset. Find your Standby URL and the full OpenAPI description in the API tab of this Actor.

Integrations

Run it on a schedule, call it from the Apify API, or connect it to Zapier, Make, Google Sheets, HubSpot, Slack and hundreds of other apps with Apify integrations. Webhooks let you trigger your own workflow as soon as a run finishes.

FAQ

Do I need a Tomba account or API key? No. Everything is built in. You only pay the per-domain price on Apify.

How much does it cost? $0.00312 per domain ($3.12 per 1,000). A count of zero is still an answer, so it is charged. Errors and cached lookups are free.

Does this give me the email addresses? No. It tells you how many addresses exist and how they break down, so you can decide where to focus. To get the addresses themselves, use Tomba Domain Search.

How many domains can I count in one run? Up to 1,000 per run, processed in parallel. There is no rate limit.

What domain format should I use? Anything works: stripe.com, www.stripe.com or https://stripe.com/pricing. We clean it up and remove duplicates.

What if my run is interrupted? It picks up where it stopped. Domains already counted are not charged again.

How do I limit what I spend? Set Maximum cost per run before you start. The Actor stops as soon as the limit is reached.
