How to Send Email from Olark with Volanea

If you need to send email from Olark, the dependable pattern is to use Olark’s completed-conversation data as the trigger, then hand the send to Volanea through a server-side automation step. This approach keeps the email API key out of the chat widget and gives you a place to validate recipients, prevent duplicates, and handle failed sends.

Olark is a live-chat product, not an email delivery service. That distinction matters: a chat transcript can tell your system that a visitor needs a follow-up, but a separate delivery provider should create and send the email. Volanea supplies the sending layer; Olark supplies the customer-interaction signal.

This guide uses Olark’s Zapier integration and its New Transcript trigger. It does not assume that Volanea has an Olark marketplace app or a native Olark plugin. Instead, Zapier receives the Olark event and forwards a deliberately small, normalized payload to an endpoint you control. That endpoint uses Volanea’s REST API to send the message.

What this Olark-to-email integration does

A completed chat is often a useful moment to send a follow-up. For example, a support team may want to send a summary after a troubleshooting conversation, a sales team may send an evaluation resource after an answered pre-sales question, or an operations team may notify a shared inbox when a high-value conversation ends.

The implementation in this guide follows this sequence:

1. An Olark conversation is completed and its transcript becomes available.
2. Zapier’s Olark app runs its New Transcript trigger.
3. Zapier maps the transcript fields into a small HTTPS request to your middleware endpoint.
4. Middleware validates the request, checks whether that transcript was already processed, and builds the email.
5. Middleware calls Volanea’s email API.
6. Volanea returns the send result, which your middleware logs alongside the Olark transcript ID.

The key architectural point is that Olark is the event source, not the application that holds your delivery credential. A visitor’s browser never receives the Volanea API key, and the chat transcript does not need to contain an email-ready HTML document.

This is also a useful separation of responsibilities. Olark agents can use the chat tool normally, while developers own recipient rules, templates, sending domains, sender reputation, observability, and failure handling.

Use Olark’s New Transcript trigger, not a browser event

The concrete trigger for this flow is New Transcript in Olark’s Zapier integration. A transcript represents a completed Olark conversation that Zapier can use as the source record for an automation.

That is different from listening for a JavaScript event in the website visitor’s browser. Browser-side code is inappropriate for an email-send workflow because it is easy to tamper with, has limited access to trustworthy conversation data, and would expose secrets if it called an email provider directly.

Why a transcript is the right business event

A transcript is generally a better trigger than the first chat message because it gives your automation a finished interaction. You can make a more useful decision with the full context:

• Did the visitor provide an email address?
• Was the conversation handled by a sales or support team?
• Does the transcript include a phrase or tag that qualifies it for follow-up?
• Is the visitor asking for a promised document, a receipt, or a support summary?
• Has your system already sent a follow-up for this specific conversation?

A transcript-triggered message should be a follow-up to a real interaction, not an automatic response to every person who opens a chat. Be conservative. If you are sending promotional content rather than a directly requested or operational follow-up, apply your normal consent and suppression rules before sending.

What Zapier receives from Olark

In this route, Olark does not post a raw HTTP webhook directly to Volanea. Zapier’s Olark connector retrieves the New Transcript record and exposes its available transcript fields for mapping. The exact fields shown in the Zap editor can vary with the transcript and the information collected during the chat.

Do not assume every transcript contains a visitor email or name. A visitor may close the chat before answering a pre-chat survey, decline to provide contact details, use an invalid address, or chat anonymously. Treat contact fields as optional input, not as a guaranteed Olark property.

For a robust integration, normalize the data at the Zapier-to-middleware boundary. Here is the payload shape your Zap should send to your endpoint; it is intentionally your own stable contract rather than a copy of a connector’s changing field labels:

{
  "event": "olark.transcript.created",
  "transcript_id": "{{Olark transcript ID}}",
  "visitor_email": "{{Olark visitor email}}",
  "visitor_name": "{{Olark visitor name}}",
  "transcript_text": "{{Olark transcript}}",
  "conversation_started_at": "{{Olark conversation start time}}",
  "conversation_ended_at": "{{Olark conversation end time}}"
}

In the Zapier field picker, select the corresponding output from the New Transcript step for each placeholder. If the connector exposes a transcript URL instead of full transcript text, send transcript_url and have your internal system retrieve or log the text through an approved process. Do not attempt to guess a transcript field name in code; inspect a real test transcript in the Zap editor first.

Build the integration with Zapier and middleware

Olark’s Zapier integration is the practical outbound automation route for this use case. The secure setup is not “Olark calls Volanea from the widget.” It is Olark → Zapier → your middleware → Volanea.

Create a Zap with an Olark New Transcript trigger. Connect the Olark account using an authorized administrator account, then test the trigger with a real non-production transcript. Verify the sample includes the identifiers and contact fields you plan to map.

For the next step, use an HTTP request action in Zapier to POST JSON to an endpoint operated by your application, serverless function, or integration service. Examples include a route in an existing backend, a Cloudflare Worker, AWS Lambda behind API Gateway, Vercel Function, or a small container service.

Recommended Zapier request configuration

Configure the HTTP action as follows:

• Method: POST
• URL: https://your-domain.example/integrations/olark/transcript
• Payload type: JSON
• Header: Content-Type: application/json
• Authentication header: a separate shared secret such as Authorization: Bearer <your-zapier-webhook-secret>
• Body: the normalized JSON object shown above

The shared secret authenticates Zapier to your middleware. It is not the Volanea API key. Keeping those credentials separate lets you revoke the automation endpoint credential without rotating the email provider key, and it limits the impact if you later replace Zapier or add a second event source.

A webhook request should be short and deterministic. Your endpoint should quickly validate and queue the work, then return a successful response. Do not make the Zap wait for a slow database query, a large transcript-processing job, or multiple downstream API calls before it receives a response.

Map the Olark transcript into an email

A direct transcript-to-email mapping is technically easy, but not always a good customer experience. First decide what message you are sending and what information belongs in it.

For a basic requested-resource follow-up, the mapping may be:

Never place raw chat text into HTML without escaping it. Chat content is user-controlled input. If you include it in an email, HTML-escape it, preserve reasonable line breaks, and consider using a short excerpt rather than the entire transcript. Full transcripts can contain personal data, credentials accidentally pasted by a visitor, internal agent notes, or information that should not be copied into another system.

A useful recipient gate

Before creating an email request, middleware should reject or route for review when any of these conditions is true:

• visitor_email is missing or fails address validation.
• The transcript ID is missing.
• The address is on your suppression or unsubscribe list for the proposed message category.
• The conversation does not meet your stated follow-up rule.
• The transcript has already produced a successful send.
• The sender domain has not been authenticated for use with Volanea.

For basic syntax and domain checks before sending, you can use a free address verification tool. Verification does not replace consent, suppression checks, or your own business logic; it simply reduces avoidable errors from malformed or risky recipient addresses.

Working middleware example: Zapier payload to Volanea REST API

The following Node.js example shows the complete field mapping. It expects the normalized JSON body from Zapier, validates the request, uses transcript_id to avoid duplicates, and sends an email through Volanea’s REST API.

Store ZAPIER_OLARK_WEBHOOK_SECRET, VOLANEA_API_KEY, OLARK_FOLLOWUP_FROM, and APP_BASE_URL in your server or serverless platform’s encrypted environment-variable store. They must not be embedded in client-side JavaScript, an Olark chat configuration snippet, or a public repository.

import express from "express";
import crypto from "node:crypto";

const app = express();
app.use(express.json({ limit: "256kb" }));

// Replace this in-memory example with a database table or durable key-value store.
// Store one row per successfully accepted transcript ID.
const processedTranscriptIds = new Set();

function escapeHtml(value = "") {
  return String(value)
    .replaceAll("&", "&")
    .replaceAll("<", "&lt;")
    .replaceAll(">", "&gt;")
    .replaceAll('"', "&quot;")
    .replaceAll("'", "&#039;");
}

function validEmail(value) {
  return typeof value === "string" && /^[^\s@]+@[^\s@]+\.[^\s@]+$/.test(value);

  const expectedBuffer = Buffer.from(expected);
  const receivedBuffer = Buffer.from(received);
  const authorized = expectedBuffer.length === receivedBuffer.length &&
    crypto.timingSafeEqual(expectedBuffer, receivedBuffer);

  if (!authorized) {
    return res.status(401).json({ error: "Unauthorized webhook request" });
  }

  const {
    event,
    transcript_id: transcriptId,
    visitor_email: visitorEmail,
    visitor_name: visitorName = "",

  }

  const safeName = escapeHtml(visitorName.trim() || "there");
  const safeExcerpt = escapeHtml(transcriptText.slice(0, 1500));
  const endedAt = escapeHtml(conversationEndedAt);

  const volaneaPayload = {

    to: [visitorEmail],
    subject: "Following up on your Olark conversation",
    html: `

    headers: {
      "X-Olark-Transcript-ID": transcriptId
    }
  };

  const response = await fetch("https://api.volanea.com/v1/emails", {
    method: "POST",
    headers: {
      "Authorization": `Bearer ${process.env.VOLANEA_API_KEY}`,
      "Content-Type": "application/json"
    },
    body: JSON.stringify(volaneaPayload)
  });

  const responseBody = await response.text();

  if (!response.ok) {
    console.error("Volanea send failed", {
      transcriptId,
      status: response.status,
      responseBody
    });
    return res.status(502).json({ error: "Email provider rejected the send" });
  }

  processedTranscriptIds.add(transcriptId);
  console.log("Olark follow-up accepted by Volanea", {
    transcriptId,
    providerResponse: responseBody
  });

  return res.status(202).json({ status: "sent", transcriptId });
});

app.listen(process.env.PORT || 3000);

Before deploying, compare the endpoint path, request schema, and authentication format against Volanea’s current API reference and setup guides. In production, replace the in-memory Set with a database-backed idempotency record that survives process restarts and concurrent requests.

Keep the Volanea API key off the Olark client

The Volanea API key belongs only in your middleware’s secret store. It should not live in Olark visitor-side configuration, the website’s JavaScript bundle, an Olark custom script, a transcript field, or a browser-accessible environment variable.

On the Olark side of this design, there is no Volanea API key at all. Olark supplies the transcript to Zapier through the authorized Olark connection. Zapier stores only the separate webhook credential used to call your middleware. Middleware holds the actual Volanea credential and is the only component permitted to call the email API.

This matters because anything delivered to a visitor’s browser can be copied. A leaked transactional-email API key can allow an attacker to send unauthorized messages, damage sender reputation, create billing exposure, and impersonate your domain.

Rotate and scope credentials deliberately

Use a distinct Volanea API key for this integration where possible, rather than sharing a general-purpose production key among unrelated services. Document its owner, the sender domains it is expected to use, and the rotation process.

Also rotate the Zapier-to-middleware secret independently. If an automation editor leaves the team or you suspect the endpoint URL was shared too broadly, you can invalidate that inbound secret without interrupting all email activity.

Decide what kind of follow-up is appropriate

A transactional or support follow-up should reflect the visitor’s expectation. “Here is the guide you asked for” and “A support agent will contact you” are different from adding someone to a marketing sequence.

For chat-driven email, classify each workflow before building it:

• Requested follow-up: a visitor asks for a document, quote, transcript, or response by email.
• Operational notification: an internal team needs notification that a conversation occurred or needs escalation.
• Support continuation: the chat ends but an agent needs to continue the case over email.
• Marketing follow-up: a prospect is enrolled in a campaign based on consent and qualification rules.

The first three commonly fit a transactional-style send, though your exact obligations depend on message content and jurisdiction. The fourth requires much more care: capture and retain consent appropriately, provide unsubscribe handling where required, honor preferences, and avoid treating a chat email field as blanket marketing permission.

Keep sender identity stable. If an agent promises that “Sam from Support” will follow up, send from a recognizable support address or use a reply-to address that reaches the appropriate team. Sending from an unmonitored mailbox creates a frustrating dead end for the visitor.

When this breaks: failures specific to the Olark-to-Zapier hop

Every automation needs a failure model. The most common errors in this workflow happen at the boundaries between a completed chat, Zapier’s trigger execution, your endpoint, and the email API.

Retries can create duplicate email sends

Automation platforms may retry a request after a timeout, connection failure, or ambiguous response. Your middleware might have successfully called Volanea but failed before it returned a response to Zapier. From Zapier’s perspective, that can look like a failed run worth retrying.

That is why transcript_id must be an idempotency key. Persist a row keyed by the Olark transcript ID before or alongside the send state. A practical state machine is received, sending, accepted, and failed. On a repeated request, return the prior outcome rather than creating a second email.

Do not key deduplication only on recipient address. One visitor can legitimately have several conversations. The unique conversation/transcript identifier is the event identity; the recipient is not.

Webhook timeouts and slow processing

A Zapier HTTP action has its own timeout behavior, and your hosting platform may have another. If your endpoint generates an AI summary, fetches a CRM record, renders a large document, and sends an email synchronously, it increases the chance that the HTTP step times out.

Return quickly after authenticating and storing the event. Put longer work on a queue, then have a worker perform enrichment and the Volanea request. The queue job should use the same transcript ID as its idempotency key.

If immediate sending is essential, keep the synchronous path small: validate, deduplicate, build a compact template, call Volanea once, store the response, and return. Monitor endpoint latency as well as provider response codes.

Missing fields and plan or configuration differences

The New Transcript sample available to Zapier only contains what Olark captured for that conversation. Visitor email is frequently absent when a pre-chat form is not used, when the visitor skips it, or when email collection is not part of the configured chat experience. Some account features and available transcript details can also depend on the Olark plan and enabled configuration.

Build a clear missing-data path. For example, if there is no valid visitor_email, return 202 with skipped_no_valid_recipient, log the transcript ID, and optionally create an internal task. Do not send to an agent address as a silent substitute unless that is an intentional, documented escalation workflow.

Transcript content is incomplete or unsuitable

A transcript may contain only a few messages, no agent response, sensitive material, or a conversation that ended unexpectedly. If your email relies on a transcript excerpt, set a minimum quality rule. You might require a completed agent response, a specific chat tag maintained by your team, or an explicit “send follow-up” phrase collected in a form.

Use a compact summary or a secure portal link when full transcript content is sensitive. Email is a durable and forwardable channel, so copying everything from chat can expand the audience and retention period for personal information.

Test the workflow before enabling it for every chat

Create a controlled test matrix before turning on the Zap for production traffic. Use a test sender domain and internal test addresses first, then test the exact Olark experience visitors will use.

At a minimum, test these cases:

1. A completed chat with a valid email and name.
2. A completed chat without an email address.
3. An address that fails validation.
4. A transcript with HTML-like text such as <script> or angle brackets.
5. The same transcript delivered twice to simulate a retry.
6. A Volanea authentication failure.
7. A temporary Volanea API failure or network timeout.
8. A conversation where the visitor should not receive marketing email.

For each test, record the Olark transcript ID, Zap run identifier, middleware request ID, Volanea response or message identifier, recipient, timestamp, and final outcome. Correlation data is the difference between “we think it sent” and being able to prove what happened.

Also verify deliverability prerequisites separately from automation correctness. Send from an authenticated domain, configure the DNS records required by your sending setup, use an aligned sender address, and monitor bounces and complaints. An automation that returns HTTP 202 can still produce poor results if the sender identity is not trusted or the recipient mailbox rejects the message.

Alternatives to a transcript-triggered send

The transcript route is right when a conversation has ended and you want to react to its outcome. It is not the only possible design.

For internal alerting, send a message to a support inbox or incident channel based on a completed transcript, but do not use the visitor’s address as the recipient. For CRM follow-up, write the transcript identifier and relevant contact fields to the CRM first, then let the CRM’s lifecycle rules decide whether a message is appropriate.

For a more complex flow, use middleware to look up the visitor by email, inspect account status, evaluate consent, and select a template. That gives your business one source of truth for communication policy instead of duplicating rules across chat automations.

Make is another middleware-like automation option if it supports the Olark event and provides the modules you need. The same security principles apply: do not expose the Volanea key to the browser, normalize variable upstream data, use a durable idempotency key, and distinguish retryable provider errors from permanent recipient or policy failures.

Operational checklist for a reliable launch

Before considering the integration complete, confirm each item below with a real test transcript:

• The Zap trigger is Olark New Transcript, not a browser-side chat event.
• The Olark account connection has appropriate administrative ownership and will not be orphaned when an employee leaves.
• A test transcript exposes the fields used in the mappings.
• The Zap sends a normalized JSON payload to an HTTPS endpoint you control.
• The middleware endpoint authenticates Zapier with a separate secret.
• The Volanea API key is stored only in server-side secret storage.
• The sender address belongs to a domain configured for your Volanea sending account.
• Missing email addresses produce a safe, logged skip rather than an accidental send.
• transcript_id is stored durably and blocks duplicate sends.
• Email HTML escapes all visitor-controlled content.
• Provider failures are logged with enough context to retry safely.
• Message category, consent, suppression, and reply handling have clear owners.

A small amount of discipline here prevents the most expensive outcomes: leaking a delivery credential, sending duplicate follow-ups, emailing people who never gave a usable address, or having no record of why a message was sent.

Conclusion

To send email from Olark with Volanea, use the completed conversation as the signal and a secure backend as the decision and delivery layer. Olark’s New Transcript trigger supplies the event through Zapier; middleware validates and deduplicates it; Volanea sends the resulting email through its REST API.

This design is more reliable than attempting to send from the chat widget and more maintainable than embedding email logic in a no-code workflow alone. It also gives you a durable place to handle the hard parts: recipient policy, secret storage, retries, transcript privacy, and deliverability.

FAQ

Can Olark send directly through a native Volanea integration?

No native Olark marketplace app or Volanea plugin is required for this approach. Use Olark’s Zapier New Transcript trigger, then call middleware that sends through Volanea’s REST API.

What Olark event should trigger the email?

Use the New Transcript trigger when the email should follow a completed chat conversation. It provides a more complete basis for rules than a browser-side chat event or an initial visitor message.

Where should I store the Volanea API key?

Store it only in server-side secret storage used by your middleware. Do not put it in the Olark widget, frontend JavaScript, a public environment variable, or Zapier request fields that are not designed as a secure server-side secret boundary.

How do I stop duplicate emails when Zapier retries?

Use the Olark transcript_id as a durable idempotency key. Save the transcript ID and outcome in a database, and return the existing outcome if the same event arrives again.

What happens if an Olark transcript has no visitor email?

Do not send a customer follow-up. Log a safe skipped outcome, optionally create an internal task, and adjust your pre-chat or agent workflow only if collecting an email is necessary and appropriate for the experience.
