GrowSurf keeps a Campaign Monitor list current. Each participant’s referral link, referral counts, referrer details, and milestone progress arrive as custom subscriber fields you can use in any campaign.

Campaign Monitor is agency-shaped: you pick a client first, then a list inside it. Get that pair right at connect time and the rest is automatic.

## Integration Steps

### Check the list has room

Campaign Monitor allows 50 custom fields per list and GrowSurf uses 15. That is comfortable for most lists, but worth checking if you have built a heavily customized one. Deleting a custom field also deletes its stored data for every subscriber, so clear space deliberately rather than mid-setup.

### Authorize Campaign Monitor

Open **Program Editor > 4. Options > Integrations** and search for Campaign Monitor.

Searching for Campaign Monitor in the GrowSurf Program Editor integrations listSearch the integrations list in Program Editor > 4. Options > Integrations.

Expand the card and select **Connect to Campaign Monitor**.

The Campaign Monitor integration card in GrowSurf with the Connect to Campaign Monitor buttonConnecting opens Campaign Monitor’s own login and authorization screen.

Log in and authorize GrowSurf.

### Choose the client, then the list

Pick the Campaign Monitor client that owns the list, then the list itself. GrowSurf adds or updates subscribers there whenever someone joins or gets referred.

Connect before importing participants. If they are already in the program, use the [existing-participant sync options](https://support.growsurf.com/article/385-how-can-i-sync-my-growsurf-participants-to-my-esp).

## Tips

#### Client and list are a pair

Switching clients later means reselecting the list. Pick the client that will still own this program in six months.

#### 50 fields is generous, not infinite

GrowSurf uses 15 of them. A list already close to the cap will fail to take the new fields.

#### Tags work in subject lines too

Campaign Monitor can insert personalization into the subject line and preview text as well as the body, so referral progress can show up in the inbox before the email is opened.
