  1. Automatically sends contacts acquired in your account to Sendy into a list of your choosing.

  2. Ability to set up custom filters to sync filters (ie, send leads from different domains to different lists or ESPs).

What you'll need

1. Your Sendy installation (URL), List ID, and API Key. Your Sendy installation is the URL that appears on your Sendy dashboard.2. To find your List ID, click Brands in the top right and choose the brand you want to use.

3. Click View all lists. Then, select and copy the List ID you want to integrate with. If you don't already have a subscriber list, you will need to create one by clicking Add a new list.

Then, choose whether you want to enable custom sync options. The List ID will appear in the text box.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: This is the URL the contact comes to your site from.
