After you connect your store to Omnisend, there will be two primary sources of data, what we sync from your store and everything you've collected with Omnisend. In this article, we look into different pieces of data and try to understand how you can use it in Omnisend.

Contacts synchronization

Every e-commerce platform has a few options for the opt-in records collection. It might be the sign-up form somewhere on the website or 'Allow marketing' check-box at the check-out page. However, different platforms have different settings; some of them let you sync your customers with subscribed status; some of them don't.

In the table presented below, we have a summary for each of the platforms, where a plus sign identifies that your contacts will be added with subscribed status, while minus represents the non-subscribed one.

With the API integration, you may define what contacts and when should be imported to the platform with subscribed status. Therefore any of the options presented in the table is available and can be implemented. The same situation with third-party applications, contacts' statuses depend on the integration type.

Non-integrated sign-up form

When you connect your store to Omnised, we are trying to capture the sign-up forms you already have in your store. If we fail or you choose to keep your forms un-integrated, the contacts will be added to your store and then synced to Omnisend within the reacquiring sync. These contacts have some common properties:

  • don't trigger Welcome automation;
  • are added to the platform with source: platform_name tag (ex. source: shopify); 
  • cannot collect opt-ins for the SMS channel.

Integrated Sign-up form

There are two types of Sign-up forms integrations. If your form is created with a different application that can be integrated with Omnisend, you should proceed with the app integration. In that case, the benefits you get will depend on the integration type. If your form comes with your store, you will be able to sync that form with the Newsletter Sign-up form and get the following benefits:

  • trigger Welcome automation
  • collect opt-ins for Email and SMS channel
  • add a tag in the Newsletter form settings
  • trigger double-opt-in message 

If we didn't manage to integrate your form automatically, proceed with the instruction provided in the articles:

Allowed marketing check-box

Some of the platforms have an Allowed marketing check-box at the check-out page, and for some of this option is the default. In case both of these conditions are true, we will be able to check whether the customer opted-in to your marketing emails through the check-out or not. This customers will:

  • not trigger the Welcome automation, but will trigger all other orders related sequences you have enabled;
  • add source: platform_name tag (ex. source: bigcommerce);
  • with the default settings, collect opt-ins for the Email channel only.

SMS opt-in collection at the check-out page

If you change your check-out settings and enable SMS channel opt-ins collection following this guide, you will be able to start collecting SMS subscribers in your Shopify store. 

After you change the legal text at the check-out page, we will also be able to get the TCPA consent to comply with the SMS sending restrictions to the US customers.


Contacts creating an account in your store do not provide explicit consent to receive your marketing. Therefore, they are synced to Omnisend with non-subscribed status. Unfortunately, it can be changed with external development help only.

If you are using Shopify, check Replacing automatic responses from Shopify article for the details.

Synchronization time

After you complete the initial integration with Omnisend, we start syncing all the data from your store, including your customers, orders, products, and categories of products. 

New data is added to Omnisend with reacquiring sync or with the events. In other words, if you have the Welcome automation enabled, the customer is synced to the platform immediately. Otherwise, it will be added with the reacquiring sync (in 1 hour for Shopify users).

In the table presented below, you can see how often each piece of data is synced.

When it comes to integrations with third-party applications, everything depends on the way this integration was developed. You may find more information in each of these articles.
