Bounceless vs Bouncer (2026): which should you pick?

Pick Bounceless if

• Fits if you verify a few thousand addresses a month
• Works for developers who want a free API allowance to start with

Look elsewhere if

• Skip it if you sign up with a Gmail or other public address, as it gets no free credits
• Tight if you want live connections, as the guides export and re-import a CSV
• Pricey if you grow, with steps up to $249 a month for 300,000 credits
• Watch out: verification does not guarantee inbox placement, the vendor says so
• Watch out: Sender Health and Inbox Placement are separate from plain checking

Pick Bouncer if

• Fits if you clean a list a few times a year and don't want a subscription
• Works for companies that want their data processed and hosted in the EU

Look elsewhere if

• Skip it if you need a new inbox warmed up or DMARC managed, as Bouncer does neither
• Pricey if you also want placement and blocklist tests, as the Deliverability Kit is sold apart from $25 a month
• Watch out: Bouncer Shield for sign-up forms is another monthly subscription, priced by the number of checks
• Tight if you want to test first, as the 100 free credits cover a sample, not a whole list
• Watch out: the monthly credit subscription shows its price only inside the calculator

Bounceless

• The free 1,000 credits a month need a work email address; public addresses get none.
• No native app integrations yet: the guides export a CSV from each platform, verify it and re-import it (Mailgun and SparkPost use their APIs).
• Verification does not guarantee inbox placement, as the vendor states: delivery also depends on sender reputation and content.
• Pay-as-you-go packs run from 5,000 credits for $19 up to 10,000,000 credits for $2,790, with no subscription.

Bouncer

• 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.

Bounceless

Single and bulk verification

Check one address in the web checker, upload a CSV list in the workspace, or call the API. Each result comes with a Keep, Review or Remove call and the reason behind it.

Catch-all resolution

Domains that accept mail for any address get a second pass, and the result stays marked as unconfirmed when the mailbox cannot be confirmed. The extra pass is included in the one-credit price.

Unconfirmed results are not billed

The pricing page says unconfirmed verification results are not charged. Credits do not expire, whether they come from a subscription or a pack.

Sign-up form checks

The Doorman tool checks an address when someone submits a form or signs up, so bad entries can be caught before they reach a list.

Sender Health and Inbox Placement

Paid plans include domain checks, email tests, monitoring and check history, plus separate inbox placement tests compared by mailbox provider.

Bouncer

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.
