SmartLead MCP. Manage Cold Email Campaigns at Scale via API.

You don't have to click through dashboards; you connect SmartLead to your AI agent and run your entire cold email campaign infrastructure straight from prompts. You manage lead lists, track performance metrics, and control sending accounts at massive scale—all without ever opening a dashboard.

Campaign Flow Control

When you need an overview of what's running, use list_campaigns to pull up a full list of every campaign set up in SmartLead. If you want the specifics on one particular sequence, run get_campaign to retrieve all the current setup and details for that named campaign.

You can instantly halt an outreach effort using pause_campaign, which stops any running campaign immediately so you don't send another email by accident. When you're ready to go again, just use resume_campaign; it reactivates the paused campaign and gets the scheduled sequence rolling again.

Lead Management and Prep Work

If you have new prospects ready for outreach, run add_lead to drop them into your SmartLead system. This tool adds those new leads so they're queued up and ready for use in future campaigns. You can also get a comprehensive inventory of every lead managed by the account across all sequences using list_leads.

To ensure you have all the data points, you can check out general details on your existing campaign setup with get_campaign before running any new leads through it.

Auditing Sending Accounts and Deliverability

Your sending accounts gotta be healthy. Use list_email_accounts to pull a list of every connected email account. This shows you the current warm-up status and scoring for each one, letting you audit your deliverability before you send anything high volume.

Performance Auditing

When it comes time to check the results, forget digging through menus. Use get_campaign_analytics to pull deep performance data on any specific campaign. This gives you metrics like open rates, click counts, and replies—the raw conversion data you need to make decisions. You can also get a summary of all campaigns' general setup details via list_campaigns before diving into the numbers.

SmartLead lets you handle entire outreach funnels using natural language prompts instead of clicking buttons. It handles multi-mailbox rotation automatically when it runs an outreach sequence, so you don't gotta worry about which account sends what.

You can combine these tools into a single workflow: First, run list_email_accounts to verify your sending accounts are warm enough; then, use add_lead to queue up the next batch of prospects; check the campaign details using get_campaign; and finally, kick it off. If you need an immediate stop, you know to hit pause_campaign.

When all that's done, you pull the final numbers with get_campaign_analytics.
