Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Bulk Email Verifier — Syntax, MX, Disposable & Deliverability Verify **thousands — or millions — of emails at once.** Paste a list and get, for every address: **syntax validity, MX/domain check, disposable & role-based detection, free-provider flag, and a deliverability score** with a clear valid / risky / invalid status. Fast, cheap and keyless — clean your lead lists before you send, and cut bounces. --- ### Why this Actor? A dirty email list wrecks your sender reputation: hard bounces, spam traps and wasted sends. Verifying emails one by one is slow, and most tools charge per credit. This Actor cleans a whole list at once — DNS-based, so it's fast and inexpensive at scale — and tells you exactly which addresses are safe to send to. - **Clean lead lists** before an outreach or newsletter campaign. - **Cut bounce rate** and protect sender reputation. - **Enrich a CRM** with deliverability status and flags. - **Filter forms/signups** by catching disposable and role-based addresses. --- ### What you get One record per email: | Field | Description | | --- | --- | | `email` | The address | | `status` | `valid`, `risky`, or `invalid` | | `isValid` | Whether it's a valid, deliverable address | | `deliverabilityScore` | 0–100 confidence score | | `reason` | Why this status | | `domain` | Email domain | | `syntaxValid` | Passes RFC syntax | | `hasMx` | Domain has MX records (can receive mail) | | `mxHost` | Primary mail server | | `isDisposable` | Disposable / temporary domain | | `isRoleBased` | Role address (info@, admin@, sales@…) | | `isFreeProvider` | Free provider (Gmail, Yahoo, Outlook…) | | `scrapedAt` | Timestamp | --- ### Example output ```json { "email": "ceo@microsoft.com", "status": "valid", "isValid": "true", "deliverabilityScore": "92", "reason": "deliverable", "domain": "microsoft.com", "syntaxValid": "true", "hasMx": "true", "mxHost": "microsoft-com.mail.protection.outlook.com", "isDisposable": "false", "isRoleBased": "false", "isFreeProvider": "false", "scrapedAt": "2026-07-08T15:00:00.000Z" } ```` - `bad@nonexistent-domain.com` → **invalid** (no MX — the domain can't receive mail). - `test@mailinator.com` → **risky** (disposable domain). - `info@company.com` → **risky** (role-based). - `john@gmail.com` → **valid** (free provider). *** ### How the status is decided | Status | Meaning | | --- | --- | | **invalid** | Bad syntax, or the domain has no MX record (cannot receive mail) — don't send. | | **risky** | Deliverable domain but disposable or role-based — send with caution. | | **valid** | Good syntax + real mail domain, not disposable, not role — safe to send. | The `deliverabilityScore` (0–100) gives you a single number to threshold on. *** ### Input | Field | Type | Default | Description | | --- | --- | --- | --- | | `emails` | array | — | **Required.** The emails to verify (thousands to millions). | | `checkDisposable` | boolean | `true` | Flag disposable/temporary domains against an up-to-date blocklist of 7,900+ domains. | | `maxConcurrency` | integer | `50` | Emails verified in parallel. | #### Example ```json { "emails": ["john@gmail.com", "info@company.com", "test@mailinator.com"], "checkDisposable": true } ``` *** ### Use cases in detail #### 1. Clean a lead list before outreach Run your list, keep `status: valid`, drop `invalid`, and review `risky` — you'll cut bounces dramatically and protect your domain's reputation. #### 2. Reduce newsletter bounce rate Verify subscribers before a big send; remove dead domains and disposables. #### 3. Enrich & segment a CRM Add `deliverabilityScore`, `isFreeProvider` and `isRoleBased` to segment personal vs business vs role contacts. #### 4. Signup / form hygiene Catch disposable and role addresses at the point of collection. *** ### How to use it 1. Click **Try for free**. 2. Paste your emails. 3. Click **Start**. 4. Export results as **JSON, CSV, Excel**, or via the Apify API. Runs are fast — domains are cached, so a big list resolves in seconds. *** ### Calling from the API ```bash curl -X POST "https://api.apify.com/v2/acts/YOUR_ACTOR_ID/runs?token=YOUR_APIFY_TOKEN" \ -H "Content-Type: application/json" \ -d '{ "emails": ["john@gmail.com", "test@mailinator.com"] }' ``` Then fetch the dataset: ```bash curl "https://api.apify.com/v2/acts/YOUR_ACTOR_ID/runs/last/dataset/items?token=YOUR_APIFY_TOKEN&format=csv" ``` Works with webhooks, Zapier, Make and n8n. *** ### Frequently asked questions **How does it check deliverability without sending?** It validates syntax, checks the domain's MX records (whether it can receive mail at all), and flags disposable, role-based and free-provider addresses. This catches the large majority of bad addresses reliably. **Does it do SMTP mailbox verification?** No — SMTP mailbox probing requires port 25 (blocked on virtually all cloud/hosting networks) and is unreliable anyway (catch-all domains, greylisting, false positives). This Actor gives you honest, fast, DNS-based verification instead of a flaky SMTP guess. **How many emails can it handle?** Thousands to millions — domains are cached, so unique-domain lookups (not per-email) drive the work. **What's a role-based address?** Addresses like `info@`, `admin@`, `sales@` that go to a team, not a person — often lower engagement and higher spam-complaint risk. **Is the disposable list current?** Yes — it fetches an up-to-date community blocklist (7,900+ domains) on each run, with a built-in fallback. *** ### Tips - **Threshold on `deliverabilityScore`** (e.g. keep ≥ 80) for a quick clean. - **Keep `valid`, drop `invalid`, review `risky`** for the safest list. - **Filter `isRoleBased` / `isFreeProvider`** to separate business from personal contacts. *** ### Notes This Actor performs DNS/MX lookups and pattern checks on the emails you provide. It does not send mail. Verify that you have the right to process the email addresses you submit, in line with applicable privacy laws (GDPR/CAN-SPAM etc.). *** ### Support Want catch-all detection, SMTP (where possible), or another flag?
