Improve your MailerLite campaign deliverability and engagement rates. ClearBounce identifies invalid, risky, and undeliverable email addresses in your MailerLite groups — then writes the results back to each subscriber as custom fields, ready for segmentation.
Identify invalid and non-existent email addresses before you send. Keep your bounce rate below 2% and protect your sender reputation.
MailerLite pricing scales with subscriber count. Stop paying to store dead contacts — clean your groups in minutes and lower your monthly bill.
Spam traps, disposable emails, and role-based addresses damage your sender score. ClearBounce flags them all before they cause harm.
Connect your MailerLite account and start verifying in under 2 minutes.
Go to your ClearBounce dashboard, open Integrations, and choose MailerLite. Paste your MailerLite API token to connect. You can generate a token in MailerLite under Integrations → MailerLite API.
Choose the MailerLite group you want to verify. ClearBounce imports the subscribers and begins the verification process automatically — already-verified addresses are skipped, so you never pay twice for the same address.
ClearBounce checks each email for syntax errors, domain validity, mailbox existence, spam traps, disposable addresses, and catch-all servers. Results are categorized as Deliverable, Undeliverable, Risky, or Unknown.
With one click, ClearBounce writes the verification status to each subscriber in MailerLite using custom fields. Use them in segments to target only safe-to-send subscribers, or to suppress invalid and risky addresses before your next campaign.
ClearBounce creates these custom fields in your MailerLite account and fills them for every verified subscriber — perfect for building segments.
clearbounce_status
The verification verdict for the contact:
clearbounce_verified_at
The date the contact was last verified, so you always know how fresh each verdict is — and can re-verify aging segments on your own schedule.
YYYY-MM-DDLog in to your MailerLite account, go to Integrations → MailerLite API, and generate a new token. Copy it and paste it into ClearBounce when connecting the integration.
No. ClearBounce only writes verification results into two custom fields. You stay in full control — use MailerLite segments to decide which subscribers to keep, suppress, or remove.
In MailerLite, create a segment with the condition field clearbounce_status equals Deliverable to target only safe subscribers — or exclude Undeliverable and Risky subscribers from your next send.
You can verify your entire MailerLite group in one go. There is no limit on group size — ClearBounce processes groups of any size efficiently, and respects MailerLite API rate limits automatically.
