GrowSurf Constant Contact setup guide Constant Contact knowledge base

GrowSurf keeps a Constant Contact list current. Each participant’s referral link, referral counts, referrer details, and milestone progress arrive as custom contact fields you can use in any email.

Setup is an authorization rather than an API key, so there is nothing to copy and nothing to rotate later.

Integration Steps

Authorize GrowSurf in Constant Contact

Open Program Editor > 4. Options > Integrations and search for Constant Contact.

Searching for Constant Contact in the GrowSurf Program Editor integrations list
Search the integrations list in Program Editor > 4. Options > Integrations.

Expand the card and select Connect to Constant Contact.

Connecting opens Constant Contact’s own login and authorization screen.

Log in and authorize GrowSurf.

Choose the list

Pick the Constant Contact list GrowSurf should keep current. Contacts are added or updated there whenever someone joins your program or gets referred.

Connect before you import participants — the sync only covers people added from that point forward. If you have already imported, use the existing-participant sync options.

Constant Contact uses double square brackets with a custom. prefix. Use them exactly as shown in your email content.

Confirm one contact before you send

Open a synced contact in Constant Contact and check the GrowSurf fields are filled in. A participant’s GrowSurf activity log records the result of every sync attempt.

Tips

One list, deliberately chosen

GrowSurf writes to the list you select. Point it at the list your referral emails actually go to, not a staging list you will forget about.

The prefix is part of the name

custom. is required. Dropping it renders an empty value rather than an error.

Connect first, import second

Doing it the other way round means backfilling by hand.
