FAQ

Can UniOne handle high-volume email sending for large marketplaces?

You bet! UniOne was built to handle scaling email volumes at a high speed, so we easily process up to 60 million of emails hourly, allowing the senders to deliver hundreds of millions of emails each month. Our marketplaces email solution is powered by a robust infrastructure designed for high-volume transactional and marketing email delivery, so your platform stays fast, reliable, and responsive at any scale.

What security measures are in place to protect my data?

UniOne takes data protection seriously. Your marketplace emails are secured with 128-bit encryption, and we host user data on servers in certified data centers across Western Europe, the US, and Canada. In addition, unlike many email marketing platforms, we don’t store the email lists on our side and even allow you to decide whether you want to handle your analytics data using our system’s capabilities or your own internal or cloud infrastructure.

How do I create personalized email templates for buyers and sellers?

With UniOne, creating personalized emails is simple and versatile. You can use our built-in template engines to customize messages for each user on your marketplace.

Choose between two options:

- Simple Template Engine – Great for basic personalization like using the buyer’s name or order ID. Just add placeholders like {{Name}} and UniOne will fill in the right info when the email is sent.
- Velocity Template Engine – A powerful tool for dynamic emails. It allows you to insert objects, arrays, loops, and conditions, allowing complex personalization of emails at scale. Whether you're sending order updates, product recommendations, or seller stats, you can build one template and let UniOne fill in the details — automatically.

Using these template tools, your emails stay fast, clean, and deeply personal — perfect for keeping both buyers and sellers engaged. And the best part? It saves lots of time on building repetitive templates allowing you to focus on your marketplace growth.
