In their own words
EmailMarker
EmailMarker verifies individual email addresses and lists to help remove invalid entries, reduce bounces, and protect sender reputation. Its checks cover syntax and typos, disposable and role-based addresses, spam traps, MX records, catch-all settings, SMTP, domain age, and a risk score. For bulk work, users can upload CSV files, review valid, invalid, risky, and unknown results, and download cleaned lists; uploads can contain up to 1 million emails. The REST JSON API supports single and bulk verification with API-key authentication, and code examples or SDKs are listed for Node.js, Python, PHP, Ruby, and Go. Integrations include Mailchimp, GetResponse, Kit, AWeber, ActiveCampaign, Klaviyo, Brevo, MailerLite, SendGrid, and Mailgun. EmailMarker is available on the web and through an API, and offers real-time form checks. The free signup includes 150 verifications at free. Paid credits are one-time purchases, starting at $3, paid once for 1,000 verifications. Results may vary and are not guaranteed to be absolutely accurate.
ZeroBounce
ZeroBounce verifies email addresses, cleans lists, and provides tools for sender reputation and inbox health. Validation is offered for bulk files and through a real-time API; the company claims 99.6% accuracy. Deliverability features include email warmup, inbox placement and server testing, blacklist and DMARC monitoring, and a dashboard. AI Email Scoring ranks addresses from 1 to 10, while Email Finder looks for professional addresses using a name and company domain. ZeroBounce lists more than 40 integrations and also supports API, SDK, and Zapier connections. An iOS app is available for list cleaning. The company says uploaded files are encrypted after TLS upload and deleted within 30 days, and that it operates its own data center and hardware rather than storing customer data on public cloud providers. A business account gets 100 free verifications per month. Pay-As-You-Go costs $39, paid once for 2,000 validations; ZeroBounce ONE costs $99 a month.
