Tools
- Check Disposable Email
Check whether one email address uses a disposable email provider. Consumes one API credit.
- Check Free Email
Check whether one email address uses a free email provider. Consumes one API credit.
- Validate Email
Run comprehensive syntax, domain, mail-server, reputation, and provider checks on one email address. The status field is the overall validation verdict; an HTTP success alone does not mean the mailbox was verified. Consumes one API credit.
Setup
- Create or open a Switchy Project.
- Open Integrations and connect MailboxValidator.
- Authorise through api_key. Switchy stores the connection against your org.
- Everyone in the Project can now @-mention the MailboxValidator tools in chat.
What teammates see: by default, memories from MailboxValidator are scoped to the Project (PROJECT visibility) - you can mark any memory PRIVATE or share it ORG-wide.
