Connect MailerLogic MCP to ChatGPT

MailerLogic MCP lets ChatGPT securely access approved MailerLogic tools after you connect and authorize your account. Once connected, you can manage contacts, send test emails, view templates, and access analytics without leaving ChatGPT.

With MailerLogic MCP, you can:

• Search and find contacts

• Create or update contacts

• Add tags to contacts

• Suppress or unsubscribe an email address

• List email templates

• Send a single transactional or test email

• View events and analytics

For security, MailerLogic MCP cannot send campaigns to your entire audience, modify billing settings, delete your account, or perform destructive bulk actions.

Before You Start

Make sure you have:

• A MailerLogic plan that includes MCP

• Access to Integrations → Apps in MailerLogic

• A ChatGPT plan that supports custom MCP apps or remote MCP servers (availability varies by plan)

Step 1: Copy the MCP Server URL

Go to 'Integrations' → 'Apps'. Open the 'MailerLogic MCP' app and copy the 'MCP Server URL'.

Generate or rotate your MCP token only if you're prompted during authorization.

Step 2: Add the MailerLogic App

Open 'ChatGPT' and go to 'Settings' → 'Apps' (or the Apps section available for your account).

Click the '+' button to add a new app.

Step 3: Enable Developer Mode

If prompted, enable Developer Mode.

Choose 'Remote MCP Server' and enter the following details:

Click Continue.

Step 4: Authorize MailerLogic

Review the app details and click 'Create'.

Step 5: Sign in with MailerLogic MCP

ChatGPT redirects you to 'MailerLogic' to complete OAuth authorization.

Step 6: Authorize AI Assistant

Click 'Authorize' to finish the setup.

Once connected, start a new ChatGPT conversation and choose the 'MailerLogic MCP' app whenever you want ChatGPT to access your MailerLogic account.

Step 7: Work with ChatGPT

Once connected, start a new ChatGPT conversation and choose the 'MailerLogic MCP' app whenever you want ChatGPT to access your MailerLogic account.

Step 8: Test the Connection

Try one of the following prompts:

• "Find contacts tagged newsletter."

• "Create a contact named Kate with email kate@example.com."

• "Add the tag prospect to kate@example.com."

• "Show my MailerLogic analytics for the last 30 days."

• "List my available email templates."

• "Suppress test@example.com from future emails."

ChatGPT may ask you to approve tool access before reading or updating data in your MailerLogic account. Review each request before approving it.

Step 9: Manage or Disconnect the Connection

In 'MailerLogic', go to 'Integrations' → 'Apps' → 'MailerLogic MCP'.

You can:

• Copy the MCP Server URL.
• Rotate your MCP token.
• Revoke access to disconnect ChatGPT.

In ChatGPT:

You can disable or remove the MailerLogic app at any time from your installed apps or plugins.

Troubleshooting

I don't see "Create App"

Custom MCP apps may not be available for your ChatGPT plan, or your workspace administrator may need to enable Developer Mode. Availability also varies by account and OpenAI rollout.

ChatGPT can't connect to MailerLogic

Verify that your server URL is exactly:

https://mcp.mailerlogic.com/mcp

OAuth authorization failed

Reconnect the app and try again. If prompted, generate a new MCP token in MailerLogic and complete the authorization process.

Some MailerLogic tools aren't available

Your MailerLogic subscription or token permissions may limit which tools ChatGPT can access.

ChatGPT says you're unauthorized

Your MCP token may have expired, been revoked, or been entered incorrectly. Rotate the token in MailerLogic and reconnect the app.

Security Best Practices

• Connect MailerLogic only to ChatGPT accounts and workspaces you trust.

• Review every tool permission request before approving it.

• Never share your MCP token in chats, documents, or screenshots.

• Revoke access immediately if you no longer need the connection.
