Justuno is a 3rd party app that provides various popups to collect new email subscribers. In this article, we explain how you can integrate your Justuno forms with Omnisend and what benefits you'll gain.



  1. Sync new subscribers and the information they submit to the Sign-up forms

  2. Trigger Welcome automation

  3. Use the information you have collected to send more targeted communication to your customers

Setup process

1.Generate an API key in your Omnisend account. Be sure to choose custom permission:

  • Contacts (allows to create, edit, download, delete subscribers). 

Learn how to create your API key on Omnisend.
2. While in the promotion management view in your Justuno account, click the paintbrush icon, next to the desired promotion in order to enter the Design Canvas.

3. While in the design canvas, click the email field. The Form Options menu appearing on the right-hand side has an option to Change Form, click that now.

4. Click Connect Provider, then click Connect ESP Provider, choose Omnisend, and finally, import your API Key.

5. Upon successful integration of Omnisend, you will now have the opportunity to create or modify your custom form. 

6. In the Form Builder menu, you can choose whether you want to add one of the fields imported from Omnisend or one of the Custom Fields offered by Justuno. Find more information on each option in the next section of the article.

Once you added the desired fields, proceed with all of the steps and choose to Update the form.

When you return to design canvas, you will note that Integration Type now reads as Omnisend.

That's it! The form is integrated and will push your contacts to your Omnisend account. But remember - you'll need to connect each Justuno promotion separately.

Capturing new subscribers and information they provide

When the integration with Omnisend is complete from the Justuno side, your email subscribers will be added to Omnisend immediately. However, apart from the email address, you may also push your customers' data.

In the Justuno form, you may choose to add input fields from Import fields and Custom fields categories.  

Import fields

All of the fields added from the Import fields category will be mapped with the default custom properties from your customers' account. If you can pass the property as a default, you should definitely do that; otherwise, you may also assign them to custom fields.

For the information to be appropriately assigned, it should match the format accepted by Omnisend. For example, if your customer enters male instead of m to the Gender input field, the information won't be accepted by Omnisend. 

Birthday date also can't assign the value to the default field, but it is automatically passed as a custom property to Omnisend. That's why this value cannot be used to trigger the automation workflow.

Note! To pass phone numbers as subscribed to the SMS channel, you need to add SMS consent to your Justuno form. Otherwise, phones will be passed to Omnisend with non-subscribed status.


To differentiate Justuno subscribers from all the other contacts, import 'Tags' field to your form as well. Make sure to make it hidden, as we don't want customers to enter any info here. So, there's no point of showing it on our Signup form. Once you add 'Tags' field to your form, 'source: justuno' tag will be passed by default.

If you have multiple forms in Justuno and want to differentiate contacts coming from different Justuno forms, you can add any other custom tags you want to be passed along with 'source: justuno' tag:

The contact with default and custom tag will look like this:

Custom fields

Custom fields will be added to Omnisend as custom properties. With this option, you can ask your customers to provide any data that is not supported in Omnisend by default. Custom properties passed by Justuno can take only string values and contain up to 2048 characters.

Name restrictions:

  • Can contain only Latin characters, numbers, "_" (underscore) sign

  • Max name length - 128 symbols

  • Name is case sensitive

Welcome automation & Personalization

Once you complete the integration with the Justuno form, all customers subscribing to this form will trigger the flow with the default trigger, set to Sign-up form is any. 

If you want to send different emails to the customers subscribing to the Justuno emails, you need to split based on the tag that Justuno contacts have (source: justuno is a default tag, but you can split based on custom ones, if you have multiple Justuno forms and want to send different Welcome emails). For example, you may create a Welcome sequence with two branches — one for customers subscribing to any Justuno form and another one for the rest of the subscribers.

Apart from triggering the Welcome automation workflow, you may also benefit from using personalization with the information you have collected from Justuno. For example, you may add the information you have collected to the Subject line or the content of the message.
