Frequently asked questions

How does the free trial work?

Once you sign up, you will receive free access to our unique StartUp 6K plan for the first four months. You only need to subscribe for it in the “Billing” section by adding your credit or debit card details. After the trial period, you can keep using it for $4 monthly if 6,000 emails are enough. At any time, if you decide to increase your email volume, modify your subscription to another plan, or require any special assistance, feel free to contact us.

How can I upgrade my account?

In the “Billing” section of your personal account, click the “Modify subscription” button to see a list of available pricing plans. You can choose any option or ask our team for a consultation.

How do I send my emails with UniOne?

At UniOne, you can send emails using our versatile Web API or connect via our easy-to-use SMTP API. Check out our documentation to learn more about each option. You can also rely on our assistance any time you need it.

Can you help me get started?

Of course! Our team is eager to help you on your email delivery journey. That’s why we’re available 24/7 in the live chat of the “Help” section (the lower right-corner icon). Also, feel free to book a call with one of our teammates if you prefer to communicate face-to-face.

How many dedicated IPs do I need?

You can start using our shared IP pools. We work tirelessly to maintain the highest email delivery rates for all our users, ensuring strict control over all our IP addresses’ reputation. However, if you decide to handle your email sender reputation independently, we are happy to share our profound expertise and assist you in making the correct decision on the number of dedicated IPs. Also, if you want to dive deeper into this topic, here’s a profound guide.

How many users come with each plan?

At UniOne, we don’t have any limitations regarding the number of users, individual projects, sending domains, or simultaneous API requests you may need. All our features are available without unnecessary restrictions for both the basic and individual plans. We’ve developed all our features to make our customers happy with our product at a fair price!

What happens if I go over my plan?

We know how crucial it is to have flawless ongoing email delivery. Thus, we've designed our billing system to allow you to receive credit for later charges. However, to reduce overages and save money, we advise choosing the pricing plan that will best fit your email-sending needs in the long term. Please contact us for more information and a free consultation on the topic.
