Perplexity

Command your outreach campaigns

The `pause_outreach_campaign` tool lets your agent halt active sequences the second you spot an error. You don't have to scramble through the Mailshake dashboard when a typo goes live. Claude Desktop reads your workspace context and triggers the pause immediately. Fetching live status is just as fast. Using `list_outreach_campaigns` alongside `get_campaign_details`, your local Claude instance pulls active metrics into your chat. You see exactly which sequences are running before you decide to intervene.

Mailshake MCP Server lead management

The `list_campaign_leads` tool pulls your qualified prospects straight into Claude's interface. Instead of exporting CSVs from the web app, you ask your agent to show who responded this week. It queries the API and formats the results right in your active conversation. You can also dig into specific interactions using `get_lead_history`. If a prospect replies, Claude fetches their entire timeline. This means you review past touchpoints and draft the perfect follow-up email without ever switching tabs.

Inject prospects and read messages

The `add_prospects_to_campaign` tool pushes new contacts into your active Mailshake sequences. When you paste a list of names and emails into Claude Web, the integration maps the JSON body and fires it off. Your outreach pipeline stays full. Tracking those conversations happens through `list_outreach_messages` and `get_message_content`. Your agent retrieves sent and received emails to analyze reply sentiment. You get an instant read on what messaging actually converts.
