> Email list verification with credits that never expire

Bouncer cleans email lists: it checks each address and marks it deliverable, risky or undeliverable, through a web app, an API or a connection to an email platform. It does not warm up inboxes or manage DMARC, but a separate Deliverability Kit runs inbox placement and blocklist tests. Verification is bought as credits that never expire, from $8 for 1,000.

## Key features

- **List verification:** Upload a CSV and get each address back as deliverable, risky, undeliverable or unknown, with reasons. Catch-all domains get a deeper check.
- **Verification API:** Synchronous and batch endpoints verify addresses from your own app, and an MCP server connects Bouncer to ChatGPT, Claude and other AI tools.
- **Toxicity Check:** Scores each address from 0 to 5 for risks such as breached or widely shared addresses, known complainers and likely spam traps.
- **Bouncer Shield:** Checks addresses as they are typed into sign-up forms and can block invalid, malicious or fraudulent entries by address or IP.
- **Deliverability Kit:** Sends test emails to see whether they land in the inbox or spam, checks SPF, DKIM and DMARC, and monitors IPs and domains on blocklists.
- **AutoClean and integrations:** Connects to email and CRM tools such as Mailchimp, HubSpot and Klaviyo to verify lists where they live, and AutoClean verifies a connected CRM without manual uploads.

## Good for

- Marketers who clean a list now and then and do not want a subscription
- Teams that also want to test inbox placement and watch blocklists
- Companies that want their data processed and hosted in the EU

## Worth knowing

- Credits can also be bought as a monthly subscription that refills each month; the page shows its price only inside the calculator.
- Bouncer Shield, for form checks, is a separate monthly subscription priced by the number of checks.
- The Deliverability Kit is sold separately from verification credits.
- Bouncer does not warm up inboxes or manage DMARC records; the kit only tests them.

## ToolGPA grades

**GPA: 2.4 out of 4**, graded Oct 18, 2026. Bouncer checks a list and tells you which addresses are safe to send to, and its credits never expire, so it suits people who clean a list a few times a year. 10,000 checks cost $60, middle of the road for list cleaners. It won't warm up an inbox or manage DMARC, though a separate kit tests where your mail lands.

- **Value for money: C.** 10,000 checks cost $60 as a one-off pack, and the credits never expire. Against the list cleaners it's listed beside that's mid-pack: MillionVerifier is $39 and NeverBounce $50, Emailable is also $60, Kickbox $70 and ZeroBounce about $129.
- **Free plan and trial: C.** No free plan, but 100 free credits to start with no card. Enough to test a sample of your list, not to clean the whole thing.
- **Features: C.** It cleans lists fully: deliverable, risky or undeliverable with reasons, a deeper catch-all check, a toxicity score and form checks. The Deliverability Kit tests placement and blocklists, but there's no warm-up or DMARC management, and the kit is sold apart.
- **Ease of use: B.** No App Store rating on record, but there's nothing to set up: upload a CSV and download it sorted, or connect Mailchimp, HubSpot or Klaviyo and check the list where it lives.
- **Platforms and integrations: B.** Web, an API and an MCP server, plus Mailchimp, HubSpot, Klaviyo, Brevo, Pipedrive, lemlist, Make and MailerLite. No phone or desktop app.

## Keep it, or make your own?

**Keep it.** Nothing Bouncer does is plain enough to make in a weekend. The 2 things listed below take a company. It costs $8, paid once.

- You could not: Checking that an address exists without writing to it.
- You could not: It plugs into other products, Mailchimp, HubSpot and Klaviyo among them, and has an API.

A judgement by ToolGPA from this listing, by rules that are the same for every tool. Nothing was built to test it.

## Works with

Mailchimp, HubSpot, Klaviyo, Brevo, Pipedrive, lemlist, Make, MailerLite
