Bouncer earned its reputation by doing one thing well: fast, no-fuss email verification with a tidy interface. It is a genuinely good pick if you live inside a particular marketing stack and want a verifier that drops in through an existing integration or a no-code automation tool. The dashboard is approachable for non-technical users, batch processing is reliable, and the API is straightforward to wire up.
Where Bouncer is the natural choice: you mostly need a one-shot pre-send cleanup, your volume is steady enough that credit expiration windows are not a worry, and the integrations Bouncer already ships cover the tools your team uses. If that describes you, it is a solid, dependable option and you may not need to switch at all.
Pre-send verification tells you whether an address looks deliverable today. It cannot tell you what your last campaign actually did. BounceShift closes that gap with crowdsourced ESP webhook reputation tracking: connect Mailgun, SendGrid, Postmark, or Amazon SES, and real bounce, delivery, and complaint outcomes feed back into the engine. Addresses are stored only as one-way hashes — raw emails are never kept — so the network gets smarter without holding your contacts.
BounceShift is also the better fit when usage is uneven. Credits never expire, so seasonal senders and agencies with lumpy client work do not lose what they paid for. Pricing starts at $0.0049 per email pay-as-you-go, with volume discounts at 100K+, and you can see the full breakdown on our pricing page.
Bouncer validates before you send, but it doesn't watch what your ESP reports afterward. BounceShift turns those real bounce and complaint signals into reputation data via our webhook integrations.
Bouncer credits carry an expiration window, which can waste budget for teams whose validation needs come in bursts. BounceShift credits never expire.
Bouncer's pricing is competitive, but BounceShift's pay-as-you-go rate starts at $0.0049/email with volume discounts kicking in at 100K+ addresses.

Drop the CSV into BounceShift (up to 100,000 emails per batch) or send addresses through our real-time REST API.
Sort by valid, invalid, and catch-all, with sub-statuses for disposable and role accounts to guide your decisions.
Push the verified addresses back into your ESP, then connect a webhook so future sends keep improving your reputation data.

A single address typically comes back in 200–500ms, which is quick enough to run inside a signup form without the user noticing. Batches of up to 100,000 addresses run in parallel in the background and notify you when the file is ready.
No. BounceShift credits never expire. Buy pay-as-you-go credits once and use them whenever you need them — useful for irregular or seasonal validation. Monthly plans are available too, and their allowances roll over.
Yes. Export your list from Bouncer as a CSV, upload it to BounceShift (up to 100,000 emails per batch) or send it through our REST API, then download the cleaned results. Your Bouncer validation history will not transfer, but re-validating is fast and you keep 100 free credits to test first.
BounceShift runs multi-layer verification: an MX-record check, an SMTP mailbox probe, disposable-domain detection, role-account detection, and catch-all detection. It also factors in crowdsourced reputation data gathered from connected ESP webhooks (Mailgun, SendGrid, Postmark, Amazon SES), where addresses are stored only as one-way hashes — raw emails are never kept.
It comes back as catch_all rather than valid, with a confidence score built from per-domain delivery history instead of a coin flip. Those addresses belong in their own segment, not in the batch you mail without thinking.
