Connect your Omnisend account so contacts can sync automatically.
Before you begin
Before connecting Omnisend to Retention.com, you'll need two things ready to go: an Omnisend API Key and a segment ID for recently added contacts. Having both on hand before you start the integration will make the setup process fast and smooth.
1. Your Omnisend API Key
Your API Key is what authorizes Retention.com to communicate with your Omnisend account securely. You'll enter this during the connection setup, so it's worth generating it first.
If you haven't created one yet, follow Omnisend's guide here: → Create an Omnisend API Key
2. A "Recently Added Contacts" Segment
This step is important: Retention.com works by identifying new contacts and adding them to your Omnisend list. To avoid paying to re-identify contacts you've already captured, you'll want to provide a segment of contacts added in the last 2 days. Retention.com will use this to check for overlap and skip anyone already in your account.
In Omnisend, create a segment with the last 2 days filter — so Retention.com doesn't re-identify contacts you already have
Name it Retention.com Recently Added Contacts — so it's easy to find
Copy and save the Segment ID somewhere safe, along with your API Key — so both are ready when you connect in Retention.com
