To get started

1. In, click Integrations from the left navigation panel in your account. Click Available Integrations at the top and choose the Omnisend icon, and click Add Now.

2. Enter your Omnisend API Key and then click Connect.

3. Set up your Contact Suppression. Once you enable automatic suppression, will sync your regular, opt-in list from your ESP and add it to your suppression list. This prevents you from paying for contacts you already have. Once you’ve enabled this option, the sync will also run daily at 6 p.m. EST.

Choose YES to suppress contacts. You'll need a Segment ID for this step, instructions for how to get this are below.

You will also need your Recent contacts Segment ID:

1. From your Omnisend dashboard, click Audience. Then, click Create segment > Date added under All Contacts.

2. Select Is in the last, type in 2 in the text field, and choose Days. Then, click Save & show contacts.

5. Paste the text you copied from the Omnisend URL into the Segment ID text box. Click Next.

6. Click Yes to enable contact sync. Next, choose the Tag you created to sync them to. Type the Tag that exactly matches the Tag you've created in Omnisend. Then, choose whether you want to enable custom sync options.

If you check the box to enable custom sync options, that will display five options: filter by email domain, full or portion of a landing page URL, landing page domain, state, and referrer URL.

This feature allows you to filter your contacts before you send them to your ESP. For example, you can send all contacts who hit different landing pages to separate lists. Or, send all of your California leads to one ESP and Texas leads to another.

Email domain: This field auto-fills/populates with email domains (ex. Gmail, Yahoo Mail, AOL, etc.) from your collected contacts.Full or portion of a landing page URL: If you've put the script on several pages or the entire site, this field allows you to pull out contacts who have only hit Landing Page A or Landing Page B. This option does not auto-populate, so you will have to add in the exact URL.Landing page domain: If you added script to both and, for example, the landing page domain would be either or This field will auto-populate.*State: This filter allows you to pull out only contacts from one or more states.Referrer URL: We can't always get referrer URL for a contact, but when we do it would be from sources like Google, Facebook, etc.*Does not apply to all plans

When you're finished, click Next.

7. Enable the integration. Once enabled, your suppression and collection sync settings will apply and begin. Click Finish.

8. Once the integration is complete, you will see the integration date, API details, contact suppression, and the option to set/change the Tag it's synced to. You can also Remove the integration from this page at the top.
