Why This Feature Matters

  • No more manual list-building. New leads captured on your website flow into your Constant Contact audience without exporting or copying contacts by hand.
  • Faster follow-up. Leads enter your Constant Contact email campaigns as soon as they sync, so your nurture emails start while their interest is fresh.
  • Consistent contact data. Syncing keeps your email marketing platform aligned with your CRM, reducing outdated or mismatched contact information.

Before You Begin

  • API Nation account required. The sync is built and managed on API Nation's platform, not inside your CRM. You'll select an API Nation subscription plan when you activate the integration. 
  • Constant Contact account required. You'll need your Constant Contact login credentials to authorize the connection.
  • CRM login credentials. You'll authorize your Sierra account during setup and must be a Primary Manager or Manager level user with permissions.

⚠️ API Nation and Constant Contact are third-party platforms, and their interfaces may change. If the screens you see differ from these steps, refer to API Nation's own documentation for the most current instructions.

Step-by-Step Instructions

  1. Go to apination.com in your web browser.
  2. Use the search bar to search for Sierra Interactive. This displays all available Sierra integrations.
  3. Select the Constant Contact integration to view its sync options.
  4. Authorize both accounts when prompted. This gives API Nation secure permission to move data between your CRM and Constant Contact.
  5. Configure the sync direction. 
  6. Select the Constant Contact list your leads should be added to. 
  7. Review the field mappings to confirm data lands in the right place — for example, that the Email field in your CRM maps to the Email field in Constant Contact. 
  8. Activate the integration. If you're not already an API Nation subscriber, you'll choose a plan at this step. Once active, your leads sync automatically based on the rules you set.

Best Practices

  • Clean your CRM data first. Merge duplicates and correct errors before your first sync so Constant Contact receives accurate contacts.
  • Segment before you sync. Decide which Constant Contact list new leads should join so your campaigns target the right audience from day one.
  • Monitor your record usage. Each contact created or updated counts toward your API Nation plan limits. Check your usage in your API Nation dashboard as your lead volume grows.

Troubleshooting Common Issues

  • Leads aren't appearing in Constant Contact.
    A lost connection is the most common cause. Open your API Nation dashboard and re-authenticate both the Sierra and Constant Contact connections.
  • Duplicate contacts in Constant Contact.
    Review your field mapping settings in API Nation. If you're using a bi-directional sync, consider switching to a one-way sync from your CRM to establish a single source of truth.
  • Sync stopped after working previously.
    You may have reached your API Nation plan's record limit. Check your usage in your API Nation account and upgrade your plan if needed.
