How do I export my MailerLite subscribers?

In MailerLite, go to Subscribers and pick the status you want from the Active subscribers dropdown. Use the dropdown arrow next to the Subscriber column to select all subscribers in the list. Click Set columns to add any fields you want in the file. Only visible columns are exported. Click Actions, then choose CSV file. Only account administrators can export. To keep group membership, add Groups under Set columns before exporting.

Will verification find the inactive subscribers on my MailerLite list?

No. Verification tells you whether an address can receive mail, not whether the person reads it. Someone who has not opened in a year can have a perfectly valid mailbox. Handle disengaged people with an engagement segment and a re-permission or sunset email, and use verification for addresses that are invalid or at risk of bouncing.

What does a risky result mean?

A risky address could not be confirmed as a real mailbox, usually because the domain accepts all mail (catch-all) or the provider will not say. An unconfirmed address is never reported as valid. Keep risky addresses out of your first send and mail them later, most engaged first.

Is there a free way to try this on my MailerLite list?

Yes. Sign in with Google and the first 100 addresses are checked free, with results to download and no card. After that, verification is $29.99 a month on the Pro plan.

Clean your MailerLite subscriber list

Export your MailerLite subscribers as a CSV, verify every address, then import the valid file back and keep the risky one out of your first send. Verification finds addresses that cannot receive mail. It cannot tell who has stopped reading, and an address it cannot confirm is called risky, never valid.

2. What MailerLite already does with bounces

MailerLite automatically removes hard-bounced subscribers from your active list. A subscriber that soft bounces three times in a row is treated as a hard bounce. (MailerLite help: hard bounce vs soft bounce)
Its anti-spam policy lists four lines at which it may suspend your account immediately: more than 5% bounces, more than 0.2% spam complaints, more than 1% unsubscribes, or fewer than 3% opens. (MailerLite anti-spam policy)

Inactive is not invalid. A subscriber who has not opened for a year usually has a working mailbox, so verification keeps them. Deal with them separately: segment by last engagement, send a re-permission email, and remove the ones who do not answer. Verification is for the addresses that would bounce.

3. What verification can and cannot tell you

It can tell you

The address is malformed or the domain has no mail servers.
The mailbox does not exist, where the provider answers the check.
The domain is disposable, which is common for junk signups.
The domain accepts all mail, so the address cannot be confirmed.

It cannot tell you

Whether the person reads your issues.
Whether they agreed to hear from you.
Whether the address is a spam trap.
Whether a risky address is real. Providers that hide mailbox status and catch-all domains stay unconfirmed.

Unconfirmed always means risky, never valid. You get three files back, valid, risky and invalid, with your original MailerLite columns kept.

4. Import the clean file back

Import the valid file as your active list. Keep the original columns so tags, names and signup dates survive.
Do not re-import the invalid file. Addresses the platform already suppressed stay suppressed, and re-adding dead ones only brings the bounces back.
Hold the risky file out of the first send. Mail it later, to the most engaged people first, and watch the bounce rate on that send.

MailerLite bounce rate limits

MailerLite may suspend an account when campaigns have more than 5% bounces, and may ask for proof of consent. It also lists more than 0.2% spam complaints, more than 1% unsubscribes and under 3% opens. Source: MailerLite anti-spam policy, read 23 Oct 2026. Other platforms' published lines are in bounce rate limits by platform.

How much is a dirty MailerLite list costing you?

Enter your own numbers. The share of dead addresses is your estimate (your last bounce rate is a floor, since only some dead addresses have bounced yet). Nothing is sent anywhere.

Check a MailerLite address, then your list

Type any address. It gets the same check the paid plans run: syntax, the domain’s mail servers and, where the provider allows it, a live mailbox check. Nothing is sent to the address.

Email address

Five checks a minute, no account needed. Nothing is sent to the address — we ask its mail server whether the mailbox exists, then disconnect.
