Set up SourceTag with Constant Contact

When a visitor submits a form with SourceTag data, the attribution fields need somewhere to go in Constant Contact. You need to create custom contact fields that match the SourceTag field names.

What you need

• SourceTag installed and form hidden fields set up
• Constant Contact account with admin access

Step 1: Go to custom fields settings

In Constant Contact, navigate to the custom fields or contact properties settings.

Step 2: Create custom fields

Create a new custom field for each SourceTag data point:

Core fields (create these)

Field name	Label	Type
st_fc_channel	First Click Channel	Text
st_fc_detail_1	First Click Smart Field 1	Text
st_fc_detail_2	First Click Smart Field 2	Text
st_fc_detail_3	First Click Smart Field 3	Text
st_fc_detail_4	First Click Smart Field 4	Text
st_lc_channel	Last Click Channel	Text
st_lc_detail_1	Last Click Smart Field 1	Text
st_lc_detail_2	Last Click Smart Field 2	Text
st_lc_detail_3	Last Click Smart Field 3	Text
st_lc_detail_4	Last Click Smart Field 4	Text
st_fc_landing_page	First Click Landing Page	Text
st_lc_landing_page	Last Click Landing Page	Text

Optional extended fields

Field name	Label	Type
st_fc_click_id	First Click Click ID	Text
st_lc_click_id	Last Click Click ID	Text
st_visits	Visit Count	Text
st_days_to_convert	Days to Convert	Text
st_device	Device Type	Text

See Captured Fields for the full list of available fields.

Step 3: Map form fields to Constant Contact fields

If your form builder sends data to Constant Contact via an integration (Zapier, native feed, webhook, etc.), make sure the SourceTag form fields are mapped to the corresponding Constant Contact custom fields.

Step 4: Test

Submit a form with UTM parameters and check the contact record in Constant Contact. The custom fields should be populated with attribution data.

Tips

• Constant Contact has a limit of 100 custom fields per account. Plan accordingly if you already have many custom fields in use.
• Constant Contact custom fields are all stored as text, so number fields like Visit Count and Days to Convert will be stored as text. This is fine for attribution tracking purposes.
• Test with a fresh contact (not one that already exists) for the cleanest test.
