# Constant Contact
## Sync with your Constant Contact List
**Step 1:** In *Campaign Editor > 4. Options > Integrations*, click the *Connect to Constant Contact* button.
{% hint style="info" %}
IMPORTANT: Because the GrowSurf data sync to Constant Contact only occurs *after* you have connected with the integration, it is imperative to connect with the integration *BEFORE* importing participants.\

{% endhint %}
**Step 2:** Log in to Constant Contact and authorize GrowSurf
**Step 3:** Once connected, choose the Constant Contact list that you want to automatically sync to. GrowSurf will add/update your Constant Contact contacts every time a new participant is added or referred to your referral campaign.

## **Troubleshooting Tips**
* **If the new participant isn't being added to Constant Contact, or if they are being added but their unique referral link isn't being synced to Constant Contact:**
* Activity logs will denote if a participant was added to Constant Contact or if they failed to be added. (In the case of failure, GrowSurf will re-attempt to add them for 7 days).
