Real output (real run on Apify, 23 Sep 2026):

Domain	Best email	Label	Phone (E.164)	Socials found	Contact form
klaviyo.com	sales@klaviyo.com	sales	–	5 (linkedin, x, facebook…)	yes
atlassian.com	press@atlassian.com	press	+14157011110	5 (linkedin, x, facebook…)	yes

Each card also carries the postal address when the site publishes one, and every email, phone and profile comes with the page it was found on.

First try: $0.008 or less, about 5 seconds. The prefilled input (apify.com, basecamp.com) returned both contact cards in 4.9 s on 24 Sep 2026.

Hollerdex vs the most-used contact details scraper (our own test)

Same 2 domains on Apify, 24 Sep 2026 (apify.com, basecamp.com), both capped at 6 pages per site. Prices are each Actor's listed prices on Apify's free plan that day.

	Hollerdex	vdrmota/contact-info-scraper (2,230 users/30 days)
Run time	4.9 s	6.4 s
Cost of this run	$0.008 (2 domains × $0.004)	$0.028 (12 pages × $0.002 + $0.004 start)
Emails found	apify.com: 2 (best: hello@apify.com); basecamp.com: 1	apify.com: 1; basecamp.com: 1
Social profiles	apify.com: 5 (LinkedIn, X, TikTok, GitHub, Discord), one per network	apify.com: 3 links (LinkedIn twice, X)
Phone noise	none returned (neither site lists a phone)	5 "uncertain" numbers such as 8675309 and 035500000000002
Best email picked + labelled (sales/support/press/personal)	yes	no (flat lists)
Contact page / contact form URL	yes	no
Pricing basis	per domain, only when something is found	per page visited, found or not

The other tool is the better pick for crawling deep into one big site (hundreds of pages) or for its paid lead-enrichment add-on; Hollerdex is built for lists of company domains.

Why Hollerdex

• One flat price per domain, not per page. Page-based scrapers visit up to 20 pages per site and charge for each one. Hollerdex goes straight to the pages that hold contact details (contact, impressum/imprint, about, support) and charges once per domain. Blocked, empty and unreachable domains cost nothing.
• Ranked and labelled, ready for an agent or a CRM. Every email is tagged role (sales, support, press, legal, careers…) or personal, the best address is picked for you, and emails that belong to other organisations (a regulator or an agency named in an imprint) are moved to otherEmails. Phones come in E.164 (+12122542246), including national numbers such as 030 1234567 on a .de site.
• Finds what simple scrapers miss. It decodes Cloudflare-protected emails, reads name [at] domain [dot] com and schema.org Organization data (emails, phones, sameAs profiles, address), and ignores share buttons, tracking addresses and logo@2x.png lookalikes.

Real example summary (from a live run, 2026-09-23):

katzsdelicatessen.com: 1 email (best: press@katzsdelicatessen.com); 1 phone; 3 social profiles (x, facebook, instagram); contact form. Checked 5 page(s).

In our test run of 40 well-known domains (SaaS, shops, restaurants, banks, EU publishers), 32 returned contacts, in about 10 seconds for the whole run. 5 were behind strong bot protection and came back blocked: true at no charge.

What you get (one record per domain)

• companyName from schema.org, the site name or the page title
• primaryEmail and emails[]: { email, type: "role" | "personal", role, onDomain, foundOn }
• primaryPhone and phones[]: { phone, e164, via: "tel-link" | "text" | "schema.org", foundOn }
• socials: the main profile per platform: linkedin, x, facebook, instagram, youtube, tiktok, github, threads, bluesky, telegram, discord, pinterest, whatsapp, crunchbase (allSocialProfiles lists every one found)
• contactPageUrl, contactFormUrl, addresses[]
• otherEmails: addresses on other domains that appeared on the site
• summary: one line an LLM can quote; found, blocked, statusCode, pagesChecked, errors

  "contactFormUrl": "https://katzsdelicatessen.com/contact",
  "blocked": false
}

Monitor mode: only contact cards that changed

Set "monitor": true to watch a list of domains. Hollerdex remembers each domain's contact card and, on the next monitor run, returns only domains whose card changed: an email, phone number or social profile was added or removed. Unchanged domains are left out of the dataset and not charged. The first monitor run returns every domain as "change": "new". Checks that read nothing (bot wall, site down, timeout) never count as "removed": the previous card is kept; if a contact page times out, only additions are reported.

{ "domains": ["apify.com", "basecamp.com"], "monitor": true, "monitorKey": "crm-accounts" }

Changed records carry three extra fields (structure shown; values depend on the site):

{
  "domain": "acme.com",
  "change": "changed",
  "changedFields": ["emails", "socials"],
  "changes": {
    "emails": { "added": ["partners@acme.com"], "removed": [] },
    "socials": { "added": ["tiktok: tiktok.com/@acme"], "removed": [] }
  }
}

monitorKey names the watchlist (several can coexist; you can add domains without starting over). Without it, the state is tied to the exact domain list. A run summary (new, changed, unchanged, failed) is saved as the run's OUTPUT record.

Who it's for

• AI agents and MCP clients asked "how do I contact acme.com?" or "find the LinkedIn and support email for these 50 companies".
• Sales and lead-gen: enrich a list of domains from a CRM, Google Maps export or trade-show list.
• Partnerships, PR and recruiting: find the right role address (press@, partners@, careers@) instead of a generic inbox.
• Market research: which companies publish a phone number, use a contact form or are active on TikTok.

Why it pays for itself

• By hand: about 2 minutes per company to open the site, find the contact page and copy the email, phone and social links (estimate), so 500 companies ≈ 16 hours; here 500 domains cost at most $2.
• Most-used Store rival vdrmota/contact-info-scraper (60,567 users) charges $0.002 per page visited on the free plan (Apify Store pricing, checked 25 Sep 2026), so 6 pages per site ≈ $0.012 per domain whether or not anything is found; CyberMax: $0.004 per domain, only when contacts are found.
• In our side-by-side run on 24 Sep 2026 (apify.com + basecamp.com), Hollerdex cost $0.008 in 4.9 s; the same 2 domains on that rival cost $0.028 in 6.4 s (details in the comparison table above).
• Monitor mode returns and charges only domains whose contacts changed, so re-checking a CRM list every week costs cents.

▶ Run it on your own list: the example input is already filled in, so the first run takes one click.

Pricing

Event	Price
Domain with contacts found (at least one email, phone or social profile)	$0.004
Domain with nothing public, blocked by bot protection, or unreachable	free

1,000 domains with contacts cost $4. You can cap the spend of any run with Apify's maximum charge setting.

When not to use it

• To find a specific person's private email: Hollerdex only reads what the company publishes on its own site.
• For sites behind heavy bot protection (some big consumer brands): they come back blocked: true, free.
• To send bulk unsolicited email: you are responsible for following anti-spam and privacy laws (CAN-SPAM, GDPR, CASL) when you use contact data.

FAQ

Why not vdrmota's Contact Details Scraper? It is the better pick for crawling hundreds of pages of one big site, and it has a paid lead-enrichment add-on. For a list of company domains, Hollerdex costs less per domain, charges nothing for misses, and picks and labels the best email for you.

Why not a people email-finder? Those tools look for named people's addresses. Hollerdex only returns what the company publishes on its own site (role addresses, phones, profiles, contact form), which is safer to use and verifiable by the page it was found on.

Why not copy it from the website myself? Fine for five companies. For a few hundred, it's hours of clicking, and you still have to normalise phone numbers and spot which email is sales vs support.

Can I call it from Python, JavaScript or plain HTTP? Yes. POST your input JSON to https://api.apify.com/v2/acts/cybermax~website-contacts/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN and the results come back in the response, or use the apify-client package for Python or JavaScript. Recipes for Make, Zapier, n8n and Google Sheets are in Integrations.

Is it legal to use? Hollerdex reads only pages a company publishes on its own website, with no login. Business emails and phone numbers can still be personal data under GDPR/CCPA, so use them for a legitimate business purpose and follow anti-spam rules (CAN-SPAM, PECR) when you contact anyone. This is general information, not legal advice.

How is this different from a page-based contact details scraper? Page-based scrapers charge per page crawled (the most-used one on the Store charges $0.002 per page, so a 5-page site costs $0.01). Hollerdex charges $0.004 once per domain, only when it finds something, and returns one ranked contact card instead of one row per page.

How much does a first run cost? $0.008 or less with the prefilled input (2 domains). No start fee, no compute charge on top; domains where nothing is found are free.

Is there a free way to try it? Apify's free plan includes monthly credit that covers over a thousand domains. The free demo page contact cards for well-known SaaS companies shows real output with no account.

Can I give it a list of URLs instead of domains? Yes. Any URL on the site works (https://www.acme.com/pricing); duplicates of the same domain are merged into one card.

Does it find personal emails? Only those a company publishes on its own site. Set includePersonalEmails: false to keep only role addresses (info@, sales@, support@).

What if a site blocks it? The domain comes back blocked: true and is free. For lists with many blocked sites, turn on proxyConfiguration.

Can an AI agent use it? Yes, through Apify's MCP server (https://mcp.apify.com/?tools=cybermax/website-contacts), and it's listed in the official MCP Registry. Each record has a one-line summary an LLM can quote.

How do I export to a CRM or Google Sheets? Use the dataset's CSV/Excel export, the Google Sheets integration, or the Make/Zapier/n8n recipes below.

Run it on a schedule

Apify Console → Schedules → Create new → cron 0 8 * * * (daily 8 AM) → Add Actor → Hollerdex with your domain list and "monitor": true. With monitor mode a daily run is cheap: you only pay for domains whose contact card changed. The same schedule through the API:

POST https://api.apify.com/v2/schedules?token=YOUR_TOKEN
{
  "name": "hollerdex-daily",
  "cronExpression": "0 8 * * *",
  "timezone": "America/New_York",
  "isEnabled": true,
  "actions": [{
    "type": "RUN_ACTOR",
    "actorId": "cybermax/website-contacts",
    "runInput": {
      "body": "{\"domains\":[\"apify.com\",\"basecamp.com\"],\"monitor\":true,\"monitorKey\":\"crm-accounts\"}",
      "contentType": "application/json"
    }
  }]
}

To get notified, open the Actor → Integrations and add an email, Slack or webhook notification on "Run succeeded" (or use the Make/Zapier/n8n recipes below).

Integrations

Make: Apify app → "Run an Actor" (Actor cybermax/website-contacts, input {"domains": ["acme.com"]}, run synchronously) → "Get dataset items" → map primaryEmail, primaryPhone, socials.linkedin into your CRM.

Zapier: Apify app → "Run Actor" action (from a new CRM company or sheet row), or the "Finished Actor Run" trigger on a scheduled monitor run → "Fetch dataset items" → update the record.

n8n: the Apify node ("Run an Actor and get dataset"), or an HTTP Request node:

POST https://api.apify.com/v2/acts/cybermax~website-contacts/run-sync-get-dataset-items?token=YOUR_TOKEN
{"domains": ["apify.com", "basecamp.com"], "includePersonalEmails": false}

Google Sheets: Apify's Google Sheets integration (Actor → Integrations), or pull the last run into a cell:

=IMPORTDATA("https://api.apify.com/v2/acts/cybermax~website-contacts/runs/last/dataset/items?format=csv&token=YOUR_TOKEN")

Python (pip install apify-client):

from apify_client import ApifyClient
client = ApifyClient("YOUR_TOKEN")
run = client.actor("cybermax/website-contacts").call(run_input={"domains": ["apify.com", "basecamp.com"]})
for card in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(card["domain"], card["primaryEmail"], card["socials"].get("linkedin"))

JavaScript (npm i apify-client):

import { ApifyClient } from 'apify-client';
const client = new ApifyClient({ token: 'YOUR_TOKEN' });
const run = await client.actor('cybermax/website-contacts').call({ domains: ['apify.com', 'basecamp.com'] });
const { items } = await client.dataset(run.defaultDatasetId).listItems();
