Send Emails via Zoho ZeptoMail

The `send_email` tool handles sending single, transactional messages. You simply provide the required `from_address`, `to_address`, subject, and either an `htmlbody` or `textbody`. This lets you write a script that reliably sends targeted emails whenever your agent needs to communicate with clients. Need to use pre-approved copy? The `send_template_email` tool manages sending by selecting from existing templates. This is perfect for high-volume processes where messaging consistency matters more than ad-hoc writing.

View and Audit Email Logs with MCP Server

Start with the `list_logs` tool to get a full overview of all email activity. This gives you a quick audit trail so you know exactly when messages were processed or failed. For deep debugging, use `get_log_details`. You pass in a specific log ID, and the agent pulls back every detail about that single interaction. It's crucial for figuring out why an email didn't hit the inbox.

Manage Email Resources with Zoho ZeptoMail

The `list_domains` tool verifies all your established domains, making sure the sender identity is solid before you send anything. You run this first to confirm everything's verified. Keep compliance in mind by running `list_suppression_list`. This shows which addresses have been suppressed, letting you prevent sending messages that will bounce or land in spam.
