This connector is on every OptinMonster plan. Official page: How to Connect OptinMonster with Constant Contact. Also attach MonsterLeads so a failed API call does not drop the lead.

1. In the campaign builder, open the Integrations view. Search for and select Constant Contact.

2. Click Register Constant Contact at the top of that panel.

3. A new window asks you to log into Constant Contact.

4. Click Allow so OptinMonster can write contacts.

5. Back in the builder, give the connection an internal name and click Connect to Constant Contact.

6. Under Email Provider Lists, pick the list new leads go to. This field is required.

7. Save the campaign.

Custom fields must already exist in Constant Contact before you map them. Coupon-wheel campaigns write the code and label to custom_field_12 and custom_field_13. Keep those values under about 36 characters. Constant Contact caps custom field values at 50 characters, and OptinMonster prefixes the string.

Test with a brand-new address. Re-submitting an existing contact often looks like a failed integration when it is just Constant Contact refusing a duplicate.
