📧 Bulk Email Verifier

Clean your email lists, reduce bounce risk, and protect your sender reputation.

Bulk Email Verifier is an Apify Actor for validating large lists of email addresses before you use them in cold outreach, CRM imports, or automation workflows. It checks each email with practical verification steps and returns structured results you can use immediately in your pipeline.

It is built for affordable bulk verification without paid third-party verification APIs.

🚀 Why use this actor?

If you run:

• cold email campaigns
• lead generation workflows
• CRM imports
• marketing automation
• scraped lead pipelines

bad email data creates avoidable problems:

• higher bounce rates
• weaker sender reputation
• wasted credits in outreach tools
• low-quality CRM records
• more manual cleanup work

Bulk Email Verifier helps you clean the list before sending, importing, or syncing it elsewhere.

✅ What this actor checks

Each email goes through several validation steps:

• Syntax validation: checks whether the email format is valid
• DNS / MX validation: checks whether the domain can receive email
• Disposable email detection: flags temporary or throwaway email providers
• Role account detection: flags generic inboxes like info@, sales@, or admin@
• Free provider signal: marks addresses from providers like Gmail or Yahoo as a separate signal

The actor labels each email as one of these statuses:

• valid
• risky
• invalid
• unknown

🎯 Typical use cases

• Google Maps scraping workflows

📥 Input options

You can provide email lists in several beginner-friendly ways:

• Raw CSV pasted directly into input
• Apify Dataset from another actor
• Apify Key-Value Store record

Provide either emails or source, not both.

⚡ Try it in 30 seconds

Use this small test input to verify a few emails quickly:

{
"emails":[
"contact@company.com",
"info@startup.io",
"hello@gmail.com"
],
"mode":"mx",
"dedupe":true,
"checkDisposable":true,
"checkRoleAccounts":true,
"output":{
"format":"dataset",
"includeReasoning":true
},
"limits":{
"maxEmails":10,
"concurrency":5
}
}

This example is also available in examples/input-inline.json.

🧩 Example inputs

The actor uses mode: "mx" for MX validation, checkRoleAccounts for role inbox detection, and source for CSV or dataset inputs. The examples below match the current input schema, so they can be pasted directly into the actor.

Quick Email Validation

Description

Verify a small list of emails before sending a campaign.

Input JSON

{
"emails":[
"contact@company.com",
"info@startup.io",
"hello@gmail.com"
],
"mode":"mx",
"checkDisposable":true,
"checkRoleAccounts":true,
"output":{
"format":"dataset",
"includeReasoning":true
}
}

Verify emails from CSV

{
"source":{
"type":"urlCsv",
"url":"https://example.com/leads.csv"
},
"mode":"mx",
"checkDisposable":true,
"checkRoleAccounts":true,
"output":{
"format":"dataset,csv",
"includeReasoning":true
}
}

The Actor automatically uses the email column if it exists, or the first column otherwise.

Verify emails from another dataset

{
"source":{
"type":"apifyDataset",
"datasetId":"DATASET_ID"
},
"mode":"mx",
"checkDisposable":true,
"checkRoleAccounts":true,
"output":{
"format":"dataset,csv",
"includeReasoning":true
}
}

If the dataset contains an email field, the Actor uses it automatically. If not, it falls back to the first field in each item.

📤 Example output

Each verified email is stored as one item in the default dataset.

{
"email":"john@example.com",
"status":"valid",
"reasons":[],
"signals":{
"syntaxOk":true,
"mxOk":true,
"mxRecords":[
{
"exchange":"mail.example.com",
"priority":10
}
],
"isDisposable":false,
"isRole":false,
"isFreeProvider":false,
"domain":"example.com"
},
"timing":{
"normalize":0,
"syntax":0,
"mx":42,
"heuristics":1
},
"reasoning":"Syntax and MX OK; no risky signals."
}

📊 Output fields

Results can be consumed from the default dataset and exported as JSON, CSV, Excel, or API responses.

If you set output.format to dataset,csv, the Actor also saves results.csv to the default Key-Value Store. Every run also saves a SUMMARY record with aggregate counts and output settings.

🛠️ Recommended setup

For most use cases:

• use mode: "mx"
• keep checkDisposable: true
• keep checkRoleAccounts: true
• enable CSV output when you want a ready-to-import file

smtp mode is experimental. If you use it, also set enableSmtp: true.

▶️ How to use

1. Open the Actor in Apify.
2. Add emails directly or connect a source such as a CSV URL or dataset.
3. Choose the verification mode. mx is the recommended default.
4. Start the run.
5. Review the dataset results and export or forward the contacts you want to keep.

💰 Pricing

The Actor uses Apify's consumption-based pricing, so cost depends on list size, concurrency, and DNS response times.

Because the Actor does not rely on paid verification APIs, it is generally a low-cost option for bulk pre-verification and list cleaning.
