When ZeroBounce is the better pick

ZeroBounce is the better pick if you need deep AI-powered email scoring, a built-in email activity data layer, or an established brand reputation that your legal team will recognise instantly. Their AI Scoring add-on predicts inbox engagement beyond simple validity — something we don't yet offer. Large enterprises that already run ZeroBounce across a wider marketing stack and value a single vendor relationship may find switching cost outweighs our lower flat rate.

When emailzeno is the better pick

emailzeno wins on total cost for senders doing more than ~10 000 verifications per month. Our Unlimited plan at $39/mo removes the "credit-counting anxiety" entirely — import a 500 k list and pay the same. EU data residency is native, not a bolt-on SCC, which simplifies your DPA. And our automatic credit refund on hard bounces means you genuinely pay only for deliverable addresses.

Moving from ZeroBounce?

Migrating from ZeroBounce? Export your suppression list from ZeroBounce's dashboard (Contacts → Suppression → Export CSV), then upload it to emailzeno's Suppression Manager on first login — it's a single-step import. Your API key format changes (prefix ec_ instead of ZB's format), but our endpoint naming mirrors the industry standard.

Frequently asked questions

Both services run SMTP-level probing without firing a DATA command. We claim 99.6 % on our internal benchmark against the same 1 M-address test set used in our public accuracy page. Independently audited comparison figures are not yet published — treat both claims as marketing until you run your own list split-test.

We have native integrations with Mailchimp, Klaviyo, ActiveCampaign, HubSpot, and 30+ others via Zapier and Make. If ZeroBounce has a specific connector you rely on, check our integrations page first — if it's missing, open a request and we typically ship in 2–3 weeks.

Our servers are in Hetzner's German data centre. Data never leaves the EU during processing. ZeroBounce offers EU residency as an enterprise option under Standard Contractual Clauses; our EU hosting is the default for every plan, simplifying your GDPR Article 28 records.
