Mailtrap is great for testing and basic email delivery, but UniOne takes you further — from sandbox to production and scaling.
Here’s why teams often choose to switch to UniOne:
| UNIONE | |

| Rich templates library | Create yours in the admin panel with 300+ ready-to-use designs and an intuitive AI-powered email builder or manage and reuse via the API |
| Dedicated support | Our support team is available 24/7 to guide your migration and setup |
| Fair pricing for all senders | No matter how many emails you send, you won’t need to pay a fortune for them, and the more your volumes increase, the less each email will cost for you. |
Getting started with UniOne is simple — most users complete the setup in under 30 minutes.
Sign up for a UniOne account. You’ll start with a free trial that includes 6,000 emails per month for four months — perfect for testing your new setup before going live.
Add your sending domain in the Settings section, and follow the on-screen instructions to set up SPF, DKIM, DMARC, and tracking domains.
Complete verification to activate sending and ensure top deliverability. Changing your domain’s DNS records may take some time, but you can start with a test sandbox domain right away.
UniOne supports both Web API and SMTP integration.
For API users: Find your API key in the Account – Security section of the admin panel. Check out our API documentation to define possible differences with your current setup, update your app’s code, API requests and endpoints to UniOne’s accordingly, and review your permissions. Additionally, feel free to check out our existing integrations and SDK libraries for faster switching.
For SMTP users: Replace Mailtrap’s credentials with UniOne’s SMTP server, port, login, and password available on the SMTP Configuration page of your admin panel.
Add your predesigned emails with API template methods or recreate them in UniOne’s intuitive AI-powered template editor. You can store, manage, and personalize templates directly through the dashboard or using API.
While UniOne allows you to monitor deliveries, reads and clicks via detailed reports and real-time logs right from the admin panel, you can also receive instant webhooks about each event related to your campaigns to be aware of the recipients’ activity the very moment it takes place. Set them up on the Webhooks page of the Settings section in the admin panel, or use our API with its Webhook methods to be on the wave of your email analytics.
Double-check all config settings — sending domains and addresses, authentication, webhooks, and custom headers. Run a few test sends, using either code from our API docs or our dedicated SMTP Debug Tool, to confirm that everything works in the way it is supposed to.
Connect UniOne with your existing system, CRM, or application. Test key automations like password resets, notifications, or welcome flows to confirm everything works seamlessly.
Start with a 4-months free trial plan giving you 6,000 monthly emails to make sure the migration went smoothly and successfully. Anytime you need assistance, feel free to contact our 24/7 support team for help in a live chat or via email. Once you feel comfortable with our service, check out the pricing plans we have for higher volumes, or book a call with us for a custom offer.
Yes! While Mailtrap is a great tool for testing and staging emails in development environments, UniOne is designed for full production delivery — handling real transactional, marketing, and automated messages at scale.
UniOne provides advanced features like 300+ predesigned email templates with a powerful AI-enhanced builder, tagging, unsubscribe management, email validation, and CSV dumps, which make it easier to personalize and control your communications.
