Integration details

Description

mailfloss is an email verification API built for developers and AI agents. Connect it to Claude to check addresses and lists without leaving the conversation. What Claude can do with mailfloss: - Verify one address in real time and explain the verdict (passed, undeliverable, risky or unknown), the reason, and any typo suggestion. - Verify a whole list as a background job, follow its progress, and report which addresses failed. - Report your plan, remaining credits, usage for a period, and past verification jobs. - List the email platforms mailfloss cleans for you, such as Klaviyo, Mailchimp and Kit, check that their credentials still work, and change their cleaning settings. Verification spends credits: 1 per address. You sign in with your mailfloss account and approve the connection, and Claude acts with your role's permissions. mailfloss is free for 500 verifications a month.
