- You want verification and campaign testing in one account: spam score, inbox placement across 7 providers, client previews and an AI assistant sit beside the verifier on the same plan. Bouncer's testing lives in a separate Deliverability Kit subscription, from $25/mo, with no rendering previews.
- You check a few addresses at a time: Unspam's verifier answers 10 addresses a day free with no account, every day. Bouncer's free tier is 100 credits once, at signup.
- You want a catch-all flagged for review rather than settled for you: Unspam reports a catch-all as a catch-all and leaves the decision to you, with a reason and a suggested action on every row.
- You want results you can read in plain language, with an AI assistant on every plan explaining what to fix in the campaign, not just the list.
A Bouncer alternative that adds spam testing and previews to verification
Bouncer is an EU-hosted email verifier that sells credits that never expire, from $8 for 1,000, and resolves catch-all addresses on Google and Microsoft mail. Unspam verifies single addresses and whole lists too, charges nothing for unknowns or duplicates, and puts spam testing, inbox placement and client previews in the same plan, from $5/mo with 10 free checks a day.

Which one fits you?
- You need a real-time check on a signup form. Bouncer has a synchronous API and Bouncer Shield, a form widget that blocks bad addresses as they are typed; Unspam's API answers asynchronously and has no form widget.
- You want catch-all addresses settled. Bouncer resolves catch-alls on Google and Microsoft infrastructure, where Unspam flags them for review.
- You clean lists inside your ESP or CRM. Bouncer lists 25 integrations, and AutoClean re-verifies HubSpot, Klaviyo, Brevo and Mailchimp contacts on a schedule you set; Unspam works from uploaded files, the API and its MCP server, and does not re-check lists on its own.
- You want a toxicity score that flags breached addresses, complainers and likely spam traps. Unspam flags disposable and role addresses, full inboxes and free providers, but has no complaint or breach data.
Why teams move from Bouncer to Unspam.
Verification and testing in one plan
A clean list is half of reaching the inbox; the other half is the email itself. Unspam runs spam tests, inbox placement across 7 providers and previews in 50+ clients on the same plan as the verifier, so one account answers both questions. Bouncer sells its testing as a separate Deliverability Kit subscription, from $25/mo, with no rendering previews.
Free checks that come back every day
Bouncer gives 100 credits once, at signup. Unspam's verifier checks up to 10 addresses a day for free, with no account and no card, which covers the everyday case of checking a lead or a reply-to address before you write to it.
Every row tells you what to do
Each address Unspam checks comes back with a status, a reason and an action (keep, review, remove or retry), and a list's downloads are already split into addresses ready to send and a suppression list. Unknowns, duplicates and malformed addresses never use a credit.

What each one costs.
Bouncer sells verification as credit packs that never expire and lists a monthly subscription that delivers the same credits each month, but publishes no subscription prices. Unknown results and duplicates are not charged. The toxicity check, Bouncer Shield and AutoClean are sold separately, and their prices are not published. Prices come from Bouncer's own pricing page.
- Free $0
Check up to 10 addresses a day on the verifier page, no account and no card. Each answer comes with a status, a reason and an action.
- Custom $5/mo
Upload whole lists (CSV or TXT, up to 100,000 rows or 20 MB), analysed for duplicates, typos and malformed rows before a credit is used. One credit per unique address with a definitive answer, from $6.40 per 1,000 down to $1.20 per 1,000 above 100,000; unknowns, duplicates and malformed addresses are free. REST API, MCP server, and spam tests, inbox placement and previews in the same plan.

Unspam vs Bouncer, answered.
Is Unspam a full replacement for Bouncer?
For list cleaning, mostly: Unspam verifies whole lists of up to 100,000 rows, single addresses, and both through its API and MCP server. Bouncer goes further in three places: a real-time signup check with a form widget, catch-all resolution on Google and Microsoft mail, and integrations that re-verify contacts inside your ESP. If you need any of those, Bouncer is the better fit today.
How does Unspam's pricing compare to Bouncer?
Bouncer sells credits that never expire, from $8 for 1,000 down to $2,000 for 1,000,000. Unspam charges one credit per unique address with a definitive answer on its Custom plan, from $6.40 per 1,000 down to $1.20 per 1,000 above 100,000, with a $5 monthly minimum. Both skip unknowns and duplicates. At small volumes Unspam costs less per address; at very large ones compare the totals for your own list size.
How do the two handle catch-all addresses?
A catch-all domain accepts every address during a check, so a probe alone cannot prove a mailbox exists. Bouncer settles catch-alls on Google and Microsoft infrastructure with its own method. Unspam reports them as catch-all with the action "review", because a guessed verdict is the one that turns into a bounce or a lost contact.
Does Unspam test emails the way Bouncer's Deliverability Kit does?
Yes, and more. Unspam's spam test scores the email against the filters, inbox placement shows where it lands at 7 providers, and previews render it in 50+ clients, all on the free plan with monthly allowances. Bouncer's Kit covers placement, a SpamAssassin test and blocklist monitoring from $25/mo, without previews.
