Protect your Instantly cold outreach deliverability. Verify your lead lists in ClearBounce first — then push only clean, deliverable addresses straight into your Instantly campaigns. No more bounces burning your sending domains.
Identify invalid and non-existent email addresses before you send. Keep your bounce rate below 2% and protect your sender reputation.
Every bounce in cold outreach damages your sending domains and mailbox warmup. Verifying leads first costs cents; replacing a burned domain costs weeks.
Spam traps, disposable emails, and role-based addresses damage your sender score. ClearBounce flags them all before they cause harm.
Connect your Instantly account and start verifying in under 2 minutes.
Go to your ClearBounce dashboard, open Integrations, and choose Instantly. Paste your Instantly API key to connect. You can find the key in Instantly under Settings → Integrations → API.
Upload your lead list to ClearBounce (or build one with the built-in Email Finder). ClearBounce verifies every address — syntax, MX records, mailbox existence, catch-all detection, disposable and role-based checks.
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.
Select an Instantly campaign and push only the deliverable leads into it with one click. Undeliverable and risky addresses never reach your sending accounts — keeping your bounce rate near zero and your domains healthy.
Cold outreach lives and dies by sender reputation. A bounce rate above 3% can get your sending domains flagged within days.
