Constant Contact
Salesforce integration.
What Constant Contact's Salesforce integration imports, which Salesforce editions it works with, and what it does not send back.
Request an integration map →Download the spec sheet →The Constant Contact Salesforce integration is Constant Contact's own connection that imports Salesforce contacts, leads and campaign members into Constant Contact lists on a schedule you set. Constant Contact says the sync is one-way: unsubscribes and contact activity are not sent back to Salesforce. It works with Salesforce Professional (with Web Services API access), Enterprise and Unlimited.
[ How it works ]
Does Constant Contact sync email activity back to Salesforce?
No. Constant Contact says the sync is one-way, and data, including unsubscribes and contact activity, isn't sent back into your Salesforce account. Getting opt-outs or activity into Salesforce needs a separate build.
[ The connector ]
Constant Contact lists, Salesforce records.
Techila Global Services is a Salesforce Summit partner. We set up Constant Contact's Salesforce imports: which contacts, leads and campaigns feed which lists, the field mapping, and the update schedule.
Where you need unsubscribes or email activity back in Salesforce, we scope and build that return flow and support it after launch.
What does the Constant Contact Salesforce integration sync?
Constant Contact's knowledge base describes three kinds of import. Each one maps Salesforce fields to Constant Contact fields and fills a new or existing list.
| Import | What comes across | Notes from Constant Contact's docs |
|---|---|---|
| Contacts list | Salesforce contacts | Mapped fields land in the Constant Contact list you pick |
| Leads list | Salesforce leads | Mapped fields land in the Constant Contact list you pick |
| Campaign list | Contacts and leads added to a Salesforce campaign | Useful when campaigns already define your audience |
| Unsubscribes and activity | Not synced back | Constant Contact says data isn't sent back into Salesforce |
Which way does Constant Contact data move?
- Contacts (from Salesforce to Constant Contact)
- Leads (from Salesforce to Constant Contact)
- Campaign members (from Salesforce to Constant Contact)
Each import has a name, an update frequency and an import type: Overwrite or Merge. You can have several scheduled imports, and you confirm you have permission to email the contacts before the import runs.
How do you connect Constant Contact to Salesforce?
- Check your Salesforce edition. Constant Contact lists Professional (with Web Services API access), Enterprise and Unlimited.
- Connect. In Constant Contact, open Integrations, find Salesforce under All Integrations, click Connect and log in to Salesforce.
- Create an import. Choose a Contacts, Leads or Campaign list import.
- Map fields. Match Salesforce fields to Constant Contact fields and save.
- Pick the source and destination. Select the Salesforce list and the Constant Contact list, existing or new.
- Set the schedule. Choose the update frequency and Overwrite or Merge, name the import, confirm permission to email and click Import.
When is the built-in integration not enough?
| Option | What it covers | Limits |
|---|---|---|
| Constant Contact's own integration | Contacts, leads and campaign members into Constant Contact lists | One-way; unsubscribes and activity stay in Constant Contact |
| Built-in imports plus a custom return flow | Opt-outs and email reporting written to Salesforce, built on Constant Contact's V3 API and Salesforce APIs or middleware | Extra build, OAuth2 set-up and monitoring to own |
| Salesforce's own marketing products | Email run inside Salesforce; see Marketing Cloud services | A larger project with its own licences |
Constant Contact's V3 API covers contacts, lists, email campaigns and reporting, including an opt-outs report, so a return flow is possible. Our Salesforce integration services cover the build; to scope it, book a discovery call. Compare other email tools on all connector pages.

Frequently asked questions.
What architects ask before commissioning a Techila integration.
No. Constant Contact says the sync is one-way, from Salesforce into Constant Contact. Unsubscribes and contact activity are not sent back to Salesforce.
Constant Contact lists Professional (with Web Services API access), Enterprise and Unlimited.
Yes. A Campaign list import brings in the contacts and leads that have been added to a Salesforce campaign.
You choose the update frequency for each import when you set it up. You can have several scheduled imports at once.
The built-in integration does not send them. A custom flow can read opt-outs through Constant Contact's V3 API and update Salesforce records.
