Zoho ZeptoMail
EmailSend transactional email through Zoho ZeptoMail from a verified sending domain. Agents deliver single HTML or plain-text messages, send template emails with merge data, and dispatch batch template sends with per-recipient personalization.
What This Integration Enables
Transactional email is the mail people actually open: receipts, resets, confirmations, shipping updates. ZeptoMail exists to keep that traffic on dedicated infrastructure with a verified sending domain, separate from marketing blasts, and this connector makes it the sending arm of any FlowRunner workflow. Agents deliver single HTML or plain-text messages, fill ZeptoMail templates with merge data, and dispatch batch template sends where each recipient gets their own personalized copy in one request. - Send transactional messages from a domain verified in the ZeptoMail account - Fill template placeholders with workflow data via merge-info objects - Batch a template to many recipients with per-recipient personalization - Track opens and clicks where the message type warrants it - Correlate sends with your own records via the client reference echoed in responses Because everything this connector does reaches a customer's inbox under your domain's reputation, the batch path runs behind FlowRunner's [human-in-the-loop](/concepts/human-in-the-loop) checks whenever volume or audience departs from the pattern.

Use Case Scenarios
Order confirmations that write their own audit trail
A [Shopify](/integrations/shopify) order triggers the agent, which maps the customer name and order details into merge info and calls Send Template Email. The response's request_id and the order number as client reference append to [Google Sheets](/integrations/google-sheets). When support asks whether order 4821's confirmation went out, the answer is a row, not an investigation.
Welcome sequences from real account events
When [Stripe](/integrations/stripe) creates a customer, the agent sends the welcome message through Send Email with open and click tracking enabled, from the verified domain rather than a founder's personal inbox. Account notifications, payment receipts, and dunning notices follow the same path, each triggered by the event that makes it true, not by a schedule that guesses.
Event confirmations, batched but individual
Registrants come in from [Typeform](/integrations/typeform). The agent builds one Send Batch Template Email call where each recipient carries their own merge info: name, session time, join details. One API request, hundreds of individually personalized confirmations. Before dispatch, the agent verifies each recipient's merge object fills every placeholder, holding back rows that would render broken, and posts those to a human instead of sending them wrong.
Human-in-Loop Highlight
Send Batch Template Email is a one-way door with a wide opening: a single call delivers a template to an entire recipient list, and a bad merge mapping does not send one embarrassing email, it sends hundreds, each addressed personally and each impossible to recall. So batch dispatch earns a checkpoint. The agent assembles the batch, renders a sample against the template, verifies per-recipient merge info covers every placeholder, and posts the summary: "312 recipients, template order-confirmation-v3, 4 rows held for missing merge fields, sample render attached." An operator approves, and only then does the batch leave. Single-message sends triggered by verified events flow without ceremony, because the blast radius of one receipt is one inbox. The gate scales with the consequence.
Agent Capabilities
3 actionsSending
3- Send Email Sends a single transactional email with an HTML and/or plain-text body, a named sender, multiple to, cc, and bcc recipients, and optional open and click tracking. Recipients accept bare addresses or Name and address pairs, comma-separated. The sender must belong to a verified domain.
- Send Template Email Sends a single email built from a ZeptoMail template, identified by template key or alias, with a merge-info object filling the template's placeholders. The default path for receipts, confirmations, and notifications with a stable layout.
- Send Batch Template Email Sends a template to many recipients in one batch request, each recipient carrying an address, optional name, and optional merge-info for individual personalization. The high-volume path, and the action this page's human gate exists for.
