Integrations Overview

Let's be honest - exporting contacts, uploading CSV files, waiting for verification, downloading results, and then manually re-importing everything back into your email platform is tedious. It's the kind of task that makes you want to put off list cleaning altogether.

That's exactly why we built direct integrations with the email marketing platforms you already use.

With Valid Email Checker integrations, you can verify and clean your email lists without ever leaving your workflow. Connect your account, select a list, import list, and we'll handle the rest. No exports. No imports. No spreadsheet juggling.

Why Integrate Your Email Platform?​

Before we dive into the platforms, here's why connecting your email marketing tools to Valid Email Checker is a game-changer:

Skip the Export-Import Dance​

Traditional email verification goes like this: export your list, upload it somewhere, wait, download results, figure out what changed, re-import the clean list, hope nothing broke.

With integrations, it's: connect, select list, verify. Done.

Keep Your Lists Clean Automatically​

Bad email data doesn't just appear overnight - it accumulates. People change jobs, abandon email addresses, and typos sneak through forms. Email data decays at roughly 2% per month, which means even a perfectly clean list today will have problems in six months.

Integrations make it easy to verify regularly because there's no friction. No excuses.

Protect What Matters​

Your sender reputation is everything. One bad campaign to a dirty list can land you in spam folders for months. Bounces hurt your sender reputation and make it harder for future emails to land in the inbox.

By cleaning lists before you send, you're protecting:

  • Deliverability - More emails reaching real inboxes
  • Sender reputation - ISPs trust you more
  • Campaign ROI - Stop paying to email addresses that don't exist
  • Analytics accuracy - Real metrics from real subscribers

Save Money on Platform Fees​

Most email marketing platforms charge based on list size. When your CRM contains outdated or invalid email addresses, you're literally paying for empty space.

tip

A list of 50,000 contacts with 15% invalid emails? That's 7,500 ghost subscribers you're paying to store and email. Clean them out and your monthly bill drops.

How Integrations Work​

Every integration follows the same simple workflow:

Step 1: Connect Your Account​

Navigate to Integrations in your Valid Email Checker dashboard, find your platform, and click Connect Account. You'll enter your API key or credentials (each guide shows you exactly where to find them).

Step 2: Select a List​

Once connected, we'll sync your available lists, segments, tags, or audiences - whatever your platform calls them. Select the one you want to verify.

Step 3: Choose Your Action​

You have two options:

  • Verify Only - We'll check every email and show you the results. You decide what to do with them.
  • Clean List Automatically - We'll verify AND automatically delete or unsubscribe invalid emails. Set it and forget it.

Step 4: Monitor Progress​

Head to Uploads & Results to watch verification progress in real-time. When it's done, you'll see a full breakdown of results.

Verification Options Explained​

When you verify through an integration, you'll see these options:

Verify Only​

Best when you want to:

  • Review results before making changes
  • Create segments based on email quality
  • Understand your list health without modifying anything

After verification, you'll see exactly which emails are safe, risky, invalid, and more. Then you can decide what to do.

Best when you want to:

  • Automatically remove bad emails
  • Keep your list clean without manual work
  • Maintain list hygiene on a regular schedule

When you enable cleaning, Valid Email Checker will automatically remove or unsubscribe emails based on the actions you configure:

Email TypeAvailable ActionsDefault
InvalidKeep, Unsubscribe, DeleteUnsubscribe
DisposableKeep, Unsubscribe, DeleteDelete
Catch-allKeep, Unsubscribe, DeleteKeep
UnknownKeep, Unsubscribe, DeleteKeep
RiskyKeep, Unsubscribe, DeleteKeep

Most users set invalid, disposable, and spam trap emails to Delete or Unsubscribe, while leaving catch-all and role accounts to Keep (these aren't necessarily bad - they just need careful handling).

Recommended Clean Settings

For most lists, we recommend:

  • Invalid → Delete
  • Disposable → Delete
  • Spam Trap → Delete
  • Role Account → Keep (these are often valid business emails)
  • Catch-All → Keep (verify results first, then decide)

This removes the definite problems while preserving potentially valid emails that just need extra attention.

Connecting Multiple Accounts​

Have multiple accounts on the same platform? No problem.

You can connect as many accounts as you need. Just give each one a unique name when connecting so you can tell them apart:

  • "Mailchimp - Main Brand"
  • "Mailchimp - Client A"
  • "Mailchimp - Newsletter"

Connected accounts appear in your Integrations dashboard with a "Connected" indicator. Reconnect or delete anytime.

Credits and Billing​

Integration verifications use the same credits as any other verification method:

  • 1 credit = 1 email verified
  • Credits deduct from your balance (Monthly → Rollover → PAYG)
  • Unknown results are automatically refunded

Before starting a verification, we'll show you the estimated credit cost based on list size. If you don't have enough credits, you'll be prompted to purchase more.

Team Members

If you're a team member, you'll use your account owner's shared credits. Your usage is tracked separately so the owner can see how many credits each team member uses.

Best Practices​

Verify Before Major Campaigns​

Running a big product launch or sale? Verify your list first. A spike in bounces during a high-volume send can trigger spam filters and hurt deliverability for weeks.

Schedule Regular Cleanings​

Don't wait until problems appear. Set a reminder to verify your main lists every 30-60 days. Lists naturally decay over time, and regular cleaning prevents small problems from becoming big ones.

Handle Catch-Alls Carefully​

Catch-all emails aren't invalid - they're just risky. Consider segmenting them and sending to a smaller test group before your main campaign. Learn more in our Catch-All Emails Guide.

Troubleshooting​

"Invalid API Key" Error​

Double-check that you copied the full API key without extra spaces. Some platforms require both an API key and a secret - make sure you have the right one.

Lists Not Appearing​

After connecting, it can take a few seconds for lists to sync. If they don't appear, try:

  1. Refreshing the page
  2. Disconnecting and reconnecting
  3. Checking that your API key has the right permissions

Verification Stuck​

If a verification seems stuck:

  1. Check your Uploads & Results page for status
  2. Large lists (100k+) can take several minutes
  3. If it's truly stuck, contact support

Platform-Specific Issues​

Each integration guide has a dedicated troubleshooting section. If you're having issues with a specific platform, check its guide first.

Frequently Asked Questions​

Do I need technical knowledge to set up integrations?​

Not at all. If you can copy and paste an API key, you can set up an integration. Each guide walks you through every step with screenshots.

Will this affect my existing email campaigns?​

Verifying a list doesn't modify anything. Only the "Clean" action makes changes, and you control exactly what gets removed.

How long does verification take?​

It depends on list size:

List SizeEstimated Time
100 emailsSeconds
1,000 emails1-2 minutes
10,000 emails5-10 minutes
100,000 emails15-30 minutes
1,000,000 emails1-2 hours

Can I verify the same list multiple times?​

Yes! You're only charged for emails that have changed or haven't been verified before. Duplicate emails within the same list aren't charged twice.

What happens to cleaned emails?​

Depending on your settings, cleaned emails are either:

  • Deleted - Removed from the list entirely
  • Unsubscribed - Marked as unsubscribed but kept for records

Is my data secure?​

Absolutely. We never store your email lists permanently. All data is deleted within 15 days, and we never share or sell your information. Read more in our Data & Privacy Policy.
