Send an email message to a contact in GoHighLevel
AI agents use send_email to create or update resources in GoHighLevel MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GoHighLevel MCP Server environment.
This tool creates and sends email messages, which is a reversible write operation. While emails cannot be unsent after delivery, the action itself is not destructive of existing data. Severity is medium because misuse could lead to spam, harassment, or phishing campaigns, but the blast radius is limited to email communications rather than financial or data deletion impacts.
From the tool's definition Tool name 'send_email' and description 'Send an email message to a contact in GoHighLevel' indicate creation and transmission of new communication data.
Documented attack patterns abuse exactly the kind of access send_email gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and GoHighLevel MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for send_email:
{
"version": "1",
"default": "deny",
"tools": {
"send_email": {
"limits": [
{
"counter": "send_email_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}send_email stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
