# Campaign Monitor
Update/add Campaign Monitor subscribers with their unique share link and referrer information.
## Sync with your Campaign Monitor List
**Step 1:** In *Program Editor > 4. Options > Integrations*, click the *Connect to Campaign Monitor* button.
{% hint style="info" %}
Connect Campaign Monitor before importing participants. If participants are already in your program, follow [these ESP sync options](https://support.growsurf.com/article/385-how-can-i-sync-my-growsurf-participants-to-my-esp) to send their GrowSurf data to Campaign Monitor.
{% endhint %}
**Step 2:** Log in to Campaign Monitor
**Step 3:** Once connected, choose a Campaign Monitor client and then select a Campaign Monitor list that you want to automatically sync to. GrowSurf will add/update your Campaign Monitor subscribers every time a new participant is added or referred to your referral or affiliate program.
## Examples
[View our Campaign Monitor tutorials](https://docs.growsurf.com/additional-integrations/campaign-monitor/tutorials) to see different kinds of examples that you can copy/paste into your email templates.
## **Subscriber Fields**
GrowSurf will automatically create these new subscriber fields for your Campaign Monitor lists.
{% hint style="danger" %}
Campaign Monitor allows up to 50 custom fields per list. Deleting a field deletes its data for every subscriber.

\**GrowSurf Referral Status* can have one of these values:

* `CREDIT_AWARDED`: The participant triggered a referral, and their referrer received credit.
* `CREDIT_EXPIRED`: The participant did not trigger a referral before the referral credit expired.
You can use these new subscriber fields in your Campaign Monitor email templates. For example, use `[GrowSurfShareURL]` to add each participant's unique referral link.

## **Troubleshooting Tips**
* Check the participant's activity logs if they do not sync. GrowSurf retries failed syncs for up to 7 days.
* **If an existing participant's information is not being synced within Campaign Monitor (e.g. referral counts, impression counts, etc) this is likely because Campaign Monitor is preventing it and returning an error to GrowSurf "***Subscriber was added too many times too quickly, try again later.***"**
* GrowSurf keeps retrying, waiting longer each time, until Campaign Monitor accepts the update. Your participants' information in Campaign Monitor then matches GrowSurf.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.growsurf.com/integrations/campaign-monitor.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
