What MailTooth is
MailTooth verifies individual email addresses and lists, returning evidence for safe, risky, or invalid results. It offers dashboard workflows for CSV and TXT uploads: choose an email column and verification depth, then download the completed results. Quick checks cost 0.5 credit, Standard checks cost 1 credit, and Deepcheck costs 2 credits. Depending on depth, checks may include syntax, MX and domain signals, disposable and role-based addresses, authentication records, blocklists, WHOIS, SMTP mailbox verification, and catch-all behavior. Single-address and bulk APIs support programmatic checks, while a JavaScript integration can check form fields before submission with configurable blocking rules. A Chrome side panel can find and verify addresses while browsing, then save results to lists or export them as CSV. Workspaces organize credits, API keys, lists, and activity with owner, admin, member, and viewer roles. A free plan provides 100 credits without a card. Paid credit packs are one-time purchases, starting with Starter at $11, paid once; credits never expire. MailTooth also connects campaigns through Resend accounts and offers a remote MCP tool, limited to one email per call.
