Email Verification for MailerLite

Clean your MailerLite subscriber list before every major campaign. Remove invalid, undeliverable, and disposable addresses to protect your sending reputation and keep your account in good standing.

How to Verify Your MailerLite List

Uses MailerLite's built-in CSV export and import. Works with all MailerLite plans including Free.

1

Export your MailerLite subscriber list

In MailerLite, go to Subscribers → select a group or all subscribers → click Export. Download the CSV file. MailerLite exports include email address, name, and custom fields.

2

Upload to StopBouncing

Upload your MailerLite CSV to StopBouncing. The email column is auto-detected. All other columns are preserved in the results file, making re-import straightforward.

3

Download your classified results

Each email is classified as Valid, Invalid, Unverifiable, or Disposable. Filter and download the addresses you want to remove from MailerLite.

4

Remove invalid subscribers in MailerLite

In MailerLite, you can unsubscribe contacts in bulk by importing a CSV with the 'unsubscribed' status, or delete them directly through the subscriber management interface.

Why Verify Your MailerLite List

Stay within MailerLite's bounce rate limits

MailerLite monitors bounce rates and restricts sending for accounts with hard bounce rates above 2–5% on a campaign. Cleaning your list before large sends keeps your account in good standing.

Improve engagement metrics

MailerLite tracks open rates and click rates per campaign. A list padded with undeliverable addresses suppresses your engagement statistics, which can affect future inbox placement with Gmail and other providers.

Protect your sender domain reputation

MailerLite sends on behalf of your verified custom domain. Bounces from your domain accumulate in sender reputation databases and affect your deliverability across all email marketing platforms.

Works with MailerLite Free and all paid plans

The CSV export/import workflow works identically across all MailerLite plans, including the free tier. No API access, OAuth, or third-party app connection is required.

Frequently Asked Questions

Does StopBouncing connect directly with MailerLite?

StopBouncing uses CSV-based verification, which works well with MailerLite's standard export and import functionality. Export your subscribers, verify with StopBouncing, then use the results to remove or unsubscribe invalid addresses. No direct integration or MailerLite API credentials are required.

What is MailerLite's bounce rate policy?

MailerLite reviews accounts with hard bounce rates above 2% on campaigns and may pause or restrict sending. Accounts with repeated high-bounce campaigns are flagged for manual review. MailerLite also applies a global suppression list — verified bounces from any account affect how other senders' messages reach those same addresses.

My MailerLite list is from a double opt-in form — do I still need to verify?

Double opt-in reduces the volume of typo and fake addresses, but it does not prevent addresses that become invalid over time. Email addresses become undeliverable when people change jobs, abandon mailboxes, or close accounts. Lists older than 6–12 months benefit significantly from re-verification even if they were originally double opt-in.

How do I remove bad emails from MailerLite after verification?

You can remove invalid addresses in MailerLite by importing a CSV with the 'unsubscribed' status for each address, which adds them to your suppression list. Alternatively, you can bulk-delete contacts from the subscriber management panel. Using the unsubscribe import is generally safer as it maintains a suppression record.

Can I verify my MailerLite import list before adding contacts?

Yes — this is the most effective approach. Before importing a new subscriber file into MailerLite, verify it with StopBouncing first. Upload only the valid addresses to MailerLite. This prevents invalid addresses from ever entering your account and is especially important for older or purchased lists.
