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

Pick Allegrow if

• Fits if you send B2B outreach and want catch-all addresses sorted out
• Works for sales teams that want list cleaning and mailbox health in one place

Look elsewhere if

• Pricey if you are one person: Starter is $99 a month for 5,000 contacts
• Pricey if you want native CRM links, as they sit on $1,340 a month billed annually
• Watch out: the trial leaves out integrations, API access and mailbox connection
• Watch out: extra users cost $40 a mailbox or user, and the Starter page gives no billing period

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

Allegrow

• The free trial excludes integrations, API access and mailbox connection.
• Starter has no native integrations and runs on credits; extra users cost $40 per mailbox or user.
• Unlimited verification and native integrations need Scale Plus Unlimited at $1,340 a month billed annually.
• The Starter price carries no billing period on the page.

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.

Allegrow

Catch-all verification

Gives catch-all addresses a Valid or Invalid status rather than leaving them as unknown.

Risk flags

Identifies spam traps, disposable addresses and inactive mailboxes, and detects each contact's primary email.

Domain health tracking

Starter connects 1 mailbox to track domain health and reputation, with automated positive email interactions.

DNS monitoring

Paid plans check SPF, DKIM and DMARC records every hour.

CRM and sales tool integrations

Scale Plus adds native integrations for HubSpot, Outreach and Salesloft and automated workflow rules.

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.
