How do I select a specific MailerLite list to verify?

Last updated May 20, 2026Integrations

MailerLite calls their lists Groups (manually curated) and Segments (filter-defined). Valid Email Checker reads both shapes through the MailerLite API and surfaces them in a single searchable picker. API key setup lives in the MailerLite integration guide.

Opening the picker

Open Integrations in the VEC sidebar.
Find the MailerLite row in Connected Integrations.
Click the three-dot menu and pick Sync Now.
A modal opens with the MailerLite logo, the connection name, and the list picker.
Pick exactly one row.

What appears in the picker

Groups — manually curated subscriber lists in MailerLite.
Segments — filter-defined dynamic groups.
Subscriber counts — pulled live from MailerLite, showing active subscribers per group/segment.
Search field — filters by name in real time.

MailerLite automations and forms are not selectable in the list picker. If you want to verify subscribers tied to a specific form, build a Group whose membership is defined by that form-source and verify the Group instead.

Sizing the cost

The credits-needed line at the bottom of the modal uses the MailerLite subscriber count. Duplicate removal (on by default) reduces the actual spend. Unknown-status results refund automatically. A 30,000-subscriber Group typically costs 27,000-29,000 credits in practice.

Segments for cost-efficient hygiene

Build a MailerLite segment like 'Subscribers created in last 30 days' and verify just that segment monthly. Cleaner Groups and lower spend than re-checking long-stable subscribers. Pair with the action defaults in the action-options FAQ.

Refreshing list data

Click the circular refresh icon at the top of the modal. VEC re-queries the MailerLite API and updates subscriber counts in place. Useful after creating new Groups or editing segment filters.

After picking the list

Below the picker, choose Verify Only (default — MailerLite untouched) or Clean List Automatically. Verify Only is the recommended starting point. Hit Import List, and you are redirected to Uploads & Results to watch progress.

Troubleshooting

Group missing from picker — your MailerLite API key may not have read access. Regenerate at Integrations → MailerLite API.
Empty picker — the MailerLite account has no Groups or Segments yet, or the key cannot read any of them.
Subscriber count zero — the Group exists but has no active subscribers. VEC blocks Import on zero-count groups.
