How to Send Email From GetResponse With Volanea

Send email from GetResponse with Volanea by connecting GetResponse’s native webhook events to a small server-side relay that maps subscriber data into a Volanea transactional email request. There is no native Volanea app or marketplace plugin for GetResponse, but GetResponse webhooks provide the outbound HTTP event you need for a direct, reliable integration.

What this GetResponse and Volanea integration does

This integration starts when a person becomes a new GetResponse contact. GetResponse calls that event Contact subscribed: it is triggered when a subscriber is added, although GetResponse notes that imports do not trigger the event.

Your webhook receiver accepts the GetResponse POST request, validates that it is intended for your endpoint, extracts the contact details, and sends a transactional email through Volanea’s POST /v1/send endpoint. A common use case is a product onboarding email, a lead handoff notification, a private resource link, or a confirmation that depends on a GetResponse signup.

The full flow looks like this:

1. A person signs up through a GetResponse form, landing page, API-connected source, or another supported subscription path.
2. GetResponse records the subscription and emits a Contact subscribed webhook.
3. GetResponse sends JSON to your HTTPS relay URL.
4. Your relay validates the webhook secret and reads the contact email, name, contact ID, list information, and event time.
5. Your relay sends the corresponding email through Volanea with a stable idempotency key.
6. The relay returns the JSON response GetResponse requires: {"status":"OK"}.

This is deliberately a server-to-server workflow. The browser that submitted the signup form never sees your Volanea secret key, and GetResponse is not asked to store that sending credential.

Why the webhook relay is the right route

GetResponse supports outbound webhooks for contact and engagement events. In the GetResponse UI, create one by going to Webhooks, selecting Create webhook, adding a webhook name and URL, choosing events, setting the webhook to active, and creating it. The event relevant to this guide is Contact subscribed.

That native webhook capability means you do not need Zapier or Make merely to receive an event when a contact subscribes. A direct webhook relay is usually better for a transactional message because it gives you control over validation, content, logs, retry behavior, and duplicate prevention.

It is also important to separate two concepts that are easy to blur together:

• GetResponse sends the event. It POSTs the subscription payload to your webhook endpoint.
• Volanea sends the email. Your endpoint uses a Volanea API key to create the transactional send.

GetResponse’s webhook configuration gives you a URL field, not a safe place to expose an email-provider authorization header to the public. The relay is the boundary between the two services.

A no-code middleware route can still be useful when you do not operate a server. GetResponse offers Zapier integration, and Zapier can make web requests. But middleware is an additional system in the delivery path. For passwordless links, account notices, lead confirmations, or other important transactional messages, a purpose-built relay gives you stronger control over authentication, idempotency, observability, and failure handling.

The concrete GetResponse trigger: Contact subscribed

The trigger for this integration is named Contact subscribed in GetResponse’s webhook event picker. It is sent when a subscriber is added to GetResponse; GetResponse specifically says it is not triggered by imports.

That distinction matters operationally. If you upload a CSV containing 10,000 contacts, this webhook will not fire for the imported rows. Do not assume an import will create 10,000 Volanea sends. If you want to email imported subscribers, use a separate intentional campaign or a controlled batch process that checks consent and sending policy first.

Configure the webhook in GetResponse

In GetResponse:

1. Open Webhooks.
2. Select Create webhook.
3. Give it a clear operational name, such as volanea-welcome-on-subscribe.
4. Enter your HTTPS receiver URL, for example https://hooks.example.com/getresponse/subscribed?secret=....
5. Select Contact subscribed as the event.
6. Keep Webhook batching off for this first implementation.
7. Change the webhook status to active.
8. Select Create webhook.

Start without batching because a single contact event maps naturally to one email send and one idempotency key. GetResponse can batch webhook events, with up to 100 event objects in an array, but batching adds a branch to your receiver. Add it later only when event volume makes it worthwhile.

Why use a separate webhook URL secret

GetResponse’s webhook documentation describes a query-string parameter as its mechanism for confirming requests are intended for your endpoint. Use a long random value, for example:

https://hooks.example.com/getresponse/subscribed?secret=long-random-value

This secret is not the Volanea API key. It is an inbound shared secret for the GetResponse-to-relay hop.

Treat it as sensitive anyway. Do not publish the complete webhook URL in source control, screenshots, ticket comments, or client-side JavaScript. Store the expected value in your relay environment as GETRESPONSE_WEBHOOK_SECRET, rotate it if it leaks, and update the GetResponse webhook URL after rotation.

The GetResponse webhook payload you receive

GetResponse webhook requests are JSON sent with HTTP POST. Webhook payloads share top-level type, account, and event fields, while contact-related events include a contact object. Requests also carry headers including X-Webhook-Type, X-Webhook-ID, and X-Request-ID.

For the Contact subscribed event, build your receiver around this shape:

{
  "type": "contact_subscribed",
  "contact": {
    "contactId": "abc123",
    "email": "ada@example.com",
    "name": "Ada Lovelace",
    "campaign": {
      "campaignId": "bcd234",
      "name": "newsletter",
      "href": "https://api.getresponse.com/v3/campaigns/bcd234"
    },
    "href": "https://api.getresponse.com/v3/contacts/abc123"
  },
  "account": {
    "accountId": "def456"
  },
  "event": {
    "occurredAt": "2026-10-05T12:56:00+00:00"
  }
}

The useful fields for the first email are normally:

Do not assume every contact has a name. GetResponse documents the contact name as nullable in its webhook payload examples. Your email must still render correctly when it is absent, blank, or only whitespace.

A safe approach is to derive a greeting name from contact.name when present and otherwise use a neutral phrase such as “there.” Do not try to infer a person’s name from the local part of their email address; ada@example.com may be valid, but billing@company.example is not a human name.

Map the GetResponse event to a Volanea email

Volanea sends a single transactional message through POST https://api.volanea.com/v1/send. Authenticate with Authorization: Bearer <your-secret-key>, send JSON, and set an Idempotency-Key for any operation that might be repeated.

The mapping below creates a welcome email using inline subject, HTML, and plain-text content. Use a From address on a domain that has already been verified in Volanea. For production configuration and endpoint details, see the email API reference and setup guides.

Field mapping at a glance

GetResponse contact.email       -> Volanea to
GetResponse contact.name        -> greetingName in subject/body
GetResponse contact.contactId   -> audit metadata / internal logs
GetResponse campaign.name       -> audience/list context
GetResponse X-Webhook-ID        -> Volanea Idempotency-Key
Your verified sender address    -> Volanea from
Your Volanea secret API key     -> Authorization: Bearer header

Working Node.js webhook receiver

The following Express receiver accepts one non-batched Contact subscribed webhook, checks the query-string secret, ignores unexpected event types, maps the event, and calls Volanea.

import express from "express";

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

const {
  GETRESPONSE_WEBHOOK_SECRET,
  VOLANEA_API_KEY,
  VOLANEA_FROM = "Example Team <hello@updates.example.com>",
  PORT = "3000",
} = process.env;

if (!GETRESPONSE_WEBHOOK_SECRET || !VOLANEA_API_KEY) {
  throw new Error("Missing GETRESPONSE_WEBHOOK_SECRET or VOLANEA_API_KEY");
}

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

app.post("/getresponse/subscribed", async (req, res) => {
  // This is the inbound GetResponse webhook secret, not the Volanea key.
  if (req.query.secret !== GETRESPONSE_WEBHOOK_SECRET) {
    return res.status(401).json({ status: "unauthorized" });
  }

  const event = req.body;
  const webhookType = req.get("X-Webhook-Type");
  const webhookId = req.get("X-Webhook-ID");

  if (event?.type !== "contact_subscribed" || webhookType !== "contact_subscribed") {
    // Return the exact acknowledgement body required by GetResponse for a handled request.
    return res.status(200).json({ status: "OK" });
  }

  const email = event?.contact?.email?.trim();
  const contactId = event?.contact?.contactId;
  const listName = event?.contact?.campaign?.name || "your list";
  const rawName = event?.contact?.name?.trim() || "";
  const greetingName = rawName ? rawName.split(/\s+/)[0] : "there";

  if (!email || !webhookId) {
    // A 4xx tells GetResponse this is a non-retryable data/configuration problem.
    return res.status(400).json({ status: "invalid_payload" });
  }

  const subject = "Welcome — here is what happens next";
  const safeName = escapeHtml(greetingName);
  const safeListName = escapeHtml(listName);

  const volaneaPayload = {
    from: VOLANEA_FROM,
    to: email,
    subject,
    html: `
      <h1>Welcome, ${safeName}</h1>
      <p>Thanks for joining ${safeListName}.</p>
      <p>We will send the next steps to this address. If you did not request this, you can ignore this email.</p>
    `,
    text: `Welcome, ${greetingName}\n\nThanks for joining ${listName}.\n\nWe will send the next steps to this address. If you did not request this, you can ignore this email.`,
  };

  try {
    const response = await fetch("https://api.volanea.com/v1/send", {
      method: "POST",
      headers: {
        Authorization: `Bearer ${VOLANEA_API_KEY}`,
        "Content-Type": "application/json",
        // GetResponse keeps this value stable when it retries the same webhook event.
        "Idempotency-Key": `getresponse:${webhookId}`,
      },
      body: JSON.stringify(volaneaPayload),
    });

    const responseBody = await response.text();

    if (!response.ok) {
      console.error("Volanea send failed", {
        status: response.status,
        webhookId,
        contactId,
        responseBody,
      });

      // A 5xx encourages GetResponse to retry this event.
      return res.status(502).json({ status: "upstream_send_failed" });
    }

    console.info("Volanea email accepted", {
      webhookId,
      contactId,
      recipient: email,
      volanea: responseBody,
    });

    return res.status(200).json({ status: "OK" });
  } catch (error) {
    console.error("Volanea request error", { webhookId, contactId, error });
    return res.status(502).json({ status: "upstream_unreachable" });
  }
});

app.listen(Number(PORT), () => {
  console.log(`Webhook relay listening on port ${PORT}`);
});

The code uses X-Webhook-ID as the idempotency basis because GetResponse says this webhook ID is unique per event and stays the same for the first delivery and retries. By contrast, X-Request-ID is unique per request attempt, so it is useful for request logs but not duplicate prevention.

Where the Volanea API key belongs

The Volanea API key belongs nowhere in GetResponse’s public-facing forms, landing pages, browser code, or webhook URL. Put it in the server-side environment or a managed secret store used by the webhook relay.

For the example above, the relay environment might contain:

GETRESPONSE_WEBHOOK_SECRET="a-long-random-inbound-secret"
VOLANEA_API_KEY="sk_live_replace-with-your-secret-key"
VOLANEA_FROM="Example Team <hello@updates.example.com>"

Your GetResponse configuration only needs the relay URL and the separate secret query parameter. It should not contain VOLANEA_API_KEY.

Why client-visible configuration is unsafe

A Volanea API key authorizes email sends. If it appears in a JavaScript bundle, a public Git repository, a GetResponse custom HTML block, a landing-page source file, or a browser network request, anyone who obtains it can potentially submit messages through your account.

That creates more than a billing problem. An exposed sending key can cause fraudulent sends, reputation damage, incident-response work, and confusion in your delivery logs. Keep the key in a server environment variable or secret manager, use separate test and production keys where available, and rotate a key immediately if it may have been exposed.

The verified From domain is also part of this control plane. A message that claims to come from an unverified sender address should not be your fallback path. Configure a From address under a domain you control and authenticate that domain before activating the webhook.

Build for speed without sacrificing reliability

GetResponse requires a webhook endpoint to process the request within five seconds. It also expects a 2xx response with a JSON body containing {"status":"OK"}; a 2xx response without that body can still be retried.

The direct code example waits for Volanea to accept the send before acknowledging GetResponse. That is straightforward and often works at low volume, but it is not the strongest production architecture for a critical message.

The production pattern: persist, acknowledge, send

For higher reliability, split the work into two stages:

1. Validate the GetResponse webhook request.
2. Store an event record or queue job keyed by X-Webhook-ID.
3. Return 200 with {"status":"OK"} immediately.
4. Have a worker send the Volanea message using the same stable idempotency key.
5. Store the Volanea result and delivery correlation data.

This pattern keeps your response below GetResponse’s timeout even if Volanea is briefly slow, your HTML rendering becomes more complex, or your application database is under load. It also gives you a durable audit trail: event received, job queued, API request accepted, message delivered, bounced, or skipped.

A durable queue does not remove the need for idempotency. A worker can crash after Volanea has accepted an email but before the worker writes its “complete” record. On restart, the queue may deliver the job again. The same Idempotency-Key prevents that retry from becoming a duplicate message.

Return the right status code

Status codes communicate retry intent to GetResponse:

• Return 200 plus {"status":"OK"} after you have durably accepted the event.
• Return 400 for malformed payloads or missing required contact data that will not become valid on retry.
• Return 401 or 403 when the inbound secret is wrong.
• Return 429 or a 5xx response for temporary capacity or upstream failures that should be retried.

GetResponse retries network/server failures, timeouts, 429, and 5xx responses three additional times at increasing intervals. It does not retry most 4xx responses. Treat that as a design tool: classify permanent input errors separately from temporary infrastructure failures.

When this breaks: GetResponse-specific failure modes

Every integration breaks eventually. The useful question is whether it fails loudly, avoids duplicate sends, and leaves enough evidence to repair the path.

GetResponse retries cause duplicate-send risk

GetResponse retries webhook delivery after a timeout, a server/network error, 429, or 5xx. It can also retry a 2xx response if the JSON response body is missing the required {"status":"OK"} acknowledgement.

The dangerous case is this sequence:

1. Your relay sends the Volanea email.
2. Volanea accepts it.
3. Your relay times out, crashes, or loses its response before acknowledging GetResponse.
4. GetResponse retries the same webhook.
5. Your relay sends the welcome message a second time.

Use X-Webhook-ID as the stable idempotency component. Do not generate a random idempotency key on each webhook attempt, and do not use X-Request-ID, because it changes per attempt.

Your endpoint exceeds GetResponse’s five-second timeout

GetResponse expects the endpoint to process the request within five seconds. Slow template rendering, DNS delays, cold starts, database waits, or a sluggish downstream API can push you over that limit.

The immediate fix is not “increase the timeout” on GetResponse. The safer fix is to make the webhook path short: authenticate, validate, record, enqueue, acknowledge. Move Volanea sending to a worker if you cannot reliably complete it within the allowed window.

Also test with the same hosting model you will use in production. A local tunnel can mask cold-start or network behavior that becomes visible only after deployment.

Contact fields are missing or unsuitable

contact.email is required for this integration, but contact.name can be absent. Your mapping must tolerate a null or blank name. If you later depend on custom fields, do not assume they are always populated just because your main signup form asks for them; contacts can arrive through API imports, integrations, different forms, or old data flows.

GetResponse also documents that Contact subscribed does not fire for imports. That is not a payload failure—it is an event-coverage limitation. If your workflow needs to process imported contacts, create a separate, consent-aware import workflow rather than waiting for a webhook that will never arrive.

Batching was enabled unexpectedly

When webhook batching is enabled, GetResponse sends an array of event objects rather than one object. The receiver shown above intentionally expects a single event.

You have two options:

• Keep batching disabled for this integration.
• Update the receiver to check Array.isArray(req.body), validate each item, enqueue one job per event, and acknowledge only after the entire batch is durably recorded.

Do not simply select the first array item. That silently drops subscribers and makes the problem difficult to discover later.

The wrong event fires the email

A broad webhook may include contact moves, copies, custom-field changes, opens, and clicks. If your endpoint treats every contact payload as a new signup, people can receive a welcome email when they are moved between lists or update a profile field.

Create a webhook that includes only Contact subscribed for this purpose, and validate both event.type and X-Webhook-Type in your code. Log unexpected event types, but do not turn them into transactional sends.

Volanea accepts the request but delivery is not complete

A successful Volanea API response means the request was accepted into the sending pipeline. It is not proof that the recipient has received or opened the message.

For operational visibility, use Volanea message activity and delivery webhooks to track delivered, bounced, complained, or otherwise skipped outcomes. Keep the original GetResponse webhook ID alongside the Volanea message result in your database or logs so support teams can trace a question from “this person signed up” to “this message was accepted” to its later delivery state.

Testing the integration before activation

Test the full chain with a dedicated test list and an address you control. Do not start by attaching a webhook to your primary acquisition list.

Practical test checklist

• Confirm the webhook endpoint is HTTPS and publicly reachable.
• Use a verified Volanea From domain.
• Confirm the receiver rejects a missing or incorrect inbound secret.
• Subscribe a new test contact through the actual GetResponse path you use in production.
• Check that the webhook has type: contact_subscribed and an X-Webhook-ID header.
• Confirm the recipient, greeting fallback, list name, sender, subject, HTML, and text body are correct.
• Replay the same captured event against a safe test endpoint and verify that the idempotency key prevents a second send.
• Simulate a temporary Volanea failure and confirm your relay returns a retryable failure rather than a false success.
• Test a contact with no name.
• Verify that an imported contact does not trigger the Contact subscribed webhook, then document the separate process for imports.

Avoid using a production customer email address for repeated retry tests. Repeated welcome messages are confusing and can make a healthy implementation look broken.

Content, consent, and deliverability considerations

A GetResponse subscription event can technically trigger a Volanea email, but technical ability is not the same as a good sending decision. The recipient should reasonably expect the message as a consequence of the form, list, or action that added them.

A transactional-style confirmation can be appropriate when it delivers something the subscriber explicitly requested: a resource link, account next steps, confirmation of an inquiry, a double-opt-in-related instruction, or a relevant onboarding note. A general marketing promotion triggered only because the address entered a list may be better handled through the consent and unsubscribe mechanisms of your marketing program.

Keep the message recognizable:

• Use the brand and From address the person expects.
• State why they received the email.
• Keep the subject aligned with the action that triggered it.
• Include a usable plain-text version alongside HTML.
• Do not put sensitive information in a subject line.
• Avoid importing a list and trying to recreate welcome sends through this webhook path.

If you need a pre-send hygiene check for a manually supplied address, Volanea also provides an email address verification tool. That is useful for form QA or one-off operational checks, but it is not a substitute for consent, suppression handling, or event idempotency.

Alternatives to the direct relay

The webhook relay is the best fit when a Contact subscribed event should cause a custom transactional email and you need code-level control. It is not the only possible architecture.

Use GetResponse’s own autoresponder when the message is marketing automation

If the message is a standard onboarding sequence sent to subscribers of a GetResponse list, a GetResponse autoresponder may be simpler. GetResponse supports autoresponders tied to lists and scheduled around a subscriber’s signup timing.

Use Volanea when the email must be sent by your application infrastructure, needs custom business logic, needs to correlate with operational events, or belongs in a distinct transactional sending stream.

Use Zapier or Make when you cannot host a relay

A middleware platform can receive the GetResponse event and make an HTTP request to Volanea. It can be appropriate for low-risk internal notifications or a prototype.

Before adopting it for important email, answer these questions:

1. Where is the Volanea key stored, and who can view or edit it?
2. Can the workflow use a stable event ID as an idempotency key?
3. How do you see failed tasks and replay them safely?
4. Does a middleware timeout cause a duplicate message on replay?
5. Can you map missing names and unexpected fields safely?

If those answers are unclear, use a small relay service. A few dozen lines of server code can offer better failure semantics than a large visual workflow.

Conclusion

To send email from GetResponse with Volanea, use GetResponse’s native Contact subscribed webhook as the trigger and send it to a server-side relay. The relay validates a separate inbound webhook secret, maps contact.email and related fields into a Volanea POST /v1/send request, and uses X-Webhook-ID as a stable idempotency key.

Do not look for a native GetResponse marketplace app, and do not place the Volanea API key in a GetResponse form, page, URL, or browser-visible configuration. Keep it in the relay’s environment, return {"status":"OK"} promptly to GetResponse, and use a queue when the workflow must remain reliable under retries and timeouts.

FAQ

Does Volanea have a native GetResponse integration?

No. This setup uses GetResponse’s native webhooks and a server-side relay that calls the Volanea REST API. There is no native GetResponse marketplace installation flow to use.

What GetResponse event should trigger the Volanea email?

Use Contact subscribed. GetResponse defines it as the event that notifies you when a subscriber is added. It does not trigger for imported contacts.

Where should I store the Volanea API key?

Store it only in server-side environment variables or a secret manager used by your webhook receiver. Do not put it in GetResponse forms, landing pages, custom browser JavaScript, webhook URLs, or public repositories.

How do I prevent duplicate welcome emails after a retry?

Set Volanea’s Idempotency-Key header from GetResponse’s X-Webhook-ID, such as getresponse:<webhook-id>. GetResponse keeps that webhook ID stable across retries of the same event.

Why did GetResponse retry even though my endpoint returned 200?

GetResponse requires a 2xx response plus a JSON response body containing {"status":"OK"}. A 2xx response without that required body can still be retried. It also retries temporary failures such as timeouts, 429, and 5xx responses.
