Continuum API vs ZeroBounce
ZeroBounce is a dedicated email verifier. Continuum verifies with the same depth — and also sends your transactional emails, newsletter campaigns, and cold outreach sequences from the same API key.
ZeroBounce does one thing well: high-accuracy point-in-time email verification. But once your list is clean, you still need Resend to send it, Sendy to campaign it, and Instantly to sequence it. Continuum collapses all four into one platform.
Frequently asked questions
Is Continuum as accurate as ZeroBounce on verification?
Continuum runs the same depth of check — 12 independent layers covering syntax, MX, SMTP, catch-all, disposable, role, greylisting, SPF/DKIM/DMARC, and blacklist status — plus continuous re-verification so your list never silently goes stale. And because Continuum also sends, your dashboard shows accuracy measured from your own real bounce outcomes, not a number either of us just states.
What's the real difference?
ZeroBounce cleans your list. Continuum cleans it, monitors it, sends through it, and sequences into it — all under one API key. No Resend subscription, no Sendy server, no Smartlead seat. And because Continuum also sends, a real bounce on an actual send immediately corrects that address's cached verdict and re-checks any monitor watching it — a standalone verifier only ever sees its own point-in-time probe, never whether the send it approved actually went through.
How does pricing compare?
ZeroBounce charges per credit for every re-clean. Continuum is a flat monthly subscription that includes verification, monitoring, transactional sending, campaigns, and sequences — so you're not juggling four invoices.
