Improve your Moosend campaign deliverability and engagement rates. ClearBounce identifies invalid, risky, and undeliverable email addresses in your Moosend contact lists — then writes the results back to each contact 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.
Moosend pricing scales with list size. Stop paying to store dead contacts — clean your list 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 Moosend account and start verifying in under 2 minutes.
Go to your ClearBounce dashboard, open Integrations, and choose Moosend. Paste your Moosend API key to connect. You can find your key in Moosend under Settings → API Key.
Choose the Moosend list you want to verify. ClearBounce imports the contacts and begins the verification process automatically — already-verified contacts 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 contact in Moosend using custom fields. Use them in search and segments to target only safe-to-send contacts, or to suppress invalid and risky addresses before your next campaign.
ClearBounce creates these custom fields in your Moosend list and fills them for every verified contact — 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.

No. ClearBounce only writes verification results into two custom fields. You stay in full control — use Moosend segments to decide which contacts to keep, suppress, or remove.
