In their own words
Emailable
Emailable verifies email addresses for cleaner mailing lists and better deliverability. Users can upload lists in bulk, customize exports, and view reports, or add a customizable widget that checks addresses in HTML forms as they are entered. Deliverability tools include inbox placement reports, blacklist monitoring, and checks for DMARC, SPF, and DKIM errors. Verification examines syntax, domains, and SMTP, and identifies disposable, accept-all, free, and role-based addresses among other risks. An HTTP API and client libraries for Node.js, Ruby, and Python support developer integrations, while the service lists connections with more than 50 apps. New accounts receive 250 free credits. The monthly subscription is $32.30 per month for 5,000 credits; pay-as-you-go costs $38 once for 5,000 credits. Credits never expire and are refunded for unknown results and duplicates after list verification. Usage is one credit per verification, 100 per inbox report, and five per blacklist check. Emailable states SOC 2 Type II, GDPR, and CCPA compliance, ISO 27001-certified data centers, 24/7 support, and at least 99.99% availability.
MailboxValidator
MailboxValidator checks email addresses and mailboxes to flag invalid addresses and help reduce email bounces. It is available on the web and through an API, with single-address results returned as JSON or XML. For lists, users can upload text or CSV files for bulk validation. Checks cover syntax, MX records, SMTP responses, greylisting, disposable and free-provider addresses, role addresses, suppression, DMARC, strict SPF, and website reachability. The company says it tests the connection through the SMTP server without sending a message to the recipient. Listed integrations include Zapier, Make, MailChimp, Mailgun, SendGrid, HubSpot, and others; API documentation links libraries for Node.js, Ruby, PHP, Perl, Python, Java,.NET, Go, and Rust. The free API plan is free, billed per month, with 300 queries and 30-day validity. A bulk trial is free for 100 queries and 30-day validity. Yahoo validations are unsupported, and non-ASCII addresses are marked invalid syntax. The FAQ says refunds are not offered; its privacy policy says processed personal data is retained indefinitely, subject to policy limits on deletion requests.
