Verification Isn't One and Done
Lists decay 22-30% a year, and domain authentication breaks silently. RocketVerifier monitors both continuously so you're never caught off guard.
Six Monitors, Running Continuously
List health monitor
Scheduled re-verification catches decayed addresses before your next campaign, with decay-rate alerts.
SPF monitor
Continuously checks your SPF record resolves correctly and includes the right sending infrastructure.
DKIM monitor
Validates DKIM signing configuration and key rotation status.
DMARC monitor
Confirms your DMARC policy is published and enforced as intended.
Blacklist monitor
Checks your sending domains and IPs against major RBLs and alerts on new listings.
CRM auto-sync
Keeps HubSpot, Mailchimp, and outbound tools in sync with the latest verification status automatically.
Common Questions
Why do email lists need re-verification, not just a one-time check?
Email lists decay 22-30% per year - people change jobs, domains expire, mailboxes fill up. A list verified six months ago can already have a meaningfully higher bounce rate today. RocketVerifier automatically re-verifies your lists on a schedule so decay gets caught before it hurts your sender reputation.
What deliverability monitors does RocketVerifier offer?
Continuous SPF, DKIM, and DMARC record monitoring for your sending domains, plus blacklist monitoring across major RBLs. You get alerted the moment a record breaks or a domain gets listed - not weeks later when your open rates crater.
Why does domain monitoring matter more in 2026?
Gmail and Yahoo's bulk-sender authentication requirements (rolled out starting 2024, tightened through 2025-2026) mean a broken DMARC record or SPF misconfiguration can silently push your mail to spam or get it rejected outright. Continuous monitoring catches this before a send, not after.
How often are lists re-verified?
You control the cadence per list (e.g. every 30 or 60 days) from the dashboard. Only emails that were previously deliverable are re-checked by default, to avoid re-spending credits on ones already known to be bad.
