Mailcheck integration for Claude and Codex

Email & Messaging

What the Mailcheck connector can do

Mailcheck screens emails and domains for deliverability risk, flagging disposable addresses, spam indicators, and domain age issues before a message ever gets sent. A lifecycle or support Space in type.com can ask the agent to verify a specific address or validate the domain behind it, so risky signups get caught before they pollute a sending list or trigger a bounce.

One connection, many Spaces

Connect Mailcheck once, then decide which Spaces can use it in threads, skills, automations, and coding work.

FAQ

Questions people ask before connecting Mailcheck

Can Claude verify emails with Mailcheck?

Yes. With a Mailcheck connection shared to a Space, the agent can verify a specific email address or validate its domain, right from a thread.

How does type.com authenticate with Mailcheck?

Mailcheck uses an API key. An admin adds it once when creating the connection.

Can Mailcheck screening run on a schedule?

Yes. A type.com automation can verify new signup emails with Mailcheck on a schedule and flag risky ones to a channel.

Is this the same as a Mailcheck MCP server?

Not exactly. type.com uses connectors and connections to give selected Spaces access to approved app tools and data. Some connectors use hosted MCP, while others use OAuth, API keys, service accounts, or custom APIs.
