Send Transactional Emails with Our tools

In a Nutshell
Transactional email, crucial in modern communication, is triggered by users' actions. Unlike promotional emails, it fosters interactions, providing confirmations, updates, and notifications. Integral to service strategies, it ensures seamless experiences and enhances user engagement.

Essential Engagement
Transactional emails are pivotal for interactions between users and services, confirming purchases, resetting passwords, or providing updates. Timely delivery is crucial for trust and reliability, making prompt dispatch a priority for an email service provider like UniOne.

Relevant Messaging
In contrast to marketing messages, transactional emails target individual actions, ensuring immediate relevance. They convey critical information personalized and tailored, driving engagement and fostering a strong connection between users and service providers.

Transactional Email vs. Marketing Email
Transactional emails differ from marketing communication in facilitating user-initiated actions or transactions rather than promoting products or services. This ensures that such emails prioritize utility, delivering pertinent information directly impacting the user's experience with the service.

Timely Delivery

FAQ
At UniOne, we provide two ways to integrate sending transactional emails into your flow: SMTP and Web API.
With SMTP API, you only need to add the UniOne’s SMTP credentials in your application or website and add a few DNS entries for your domain. The whole process takes mere minutes!
With the Web (aka HTTP) API, you need to add some code to your website or application which will make email-send API requests containing all the required data each time you want to send a transactional email. Check out our documentation and integration libraries featuring ready-to-use SDKs in different programming languages for easier connectivity.
In terms of sending transactional emails (as they usually are single-request messages), we don’t have any limitations. You’re only limited to the sending volume included in your pricing plan if you want to avoid overages. However, you can always change to a higher one if you need to send more emails, and the bigger your sending volume is, the more attractive price you get per message. Feel free to contact us for any special offers available at the time.
Of course, you can! As with any other types of emails sent with UniOne, we provide detailed information about each transactional email you send so you can easily track the performance of these messages. Here are several ways of how you can do it:
- Process our webhooks to get real-time data on email sends, opens, clicks, unsubscribes, bounces, etc., and perform analytics using your own tools.
- Analyze the data using our visual dashboards with handy filters. Please note that while there’s a certain limit of the default data storage period depending on your sending volumes, you can always extend it for an extra fee if necessary.
- Download the event data in CSV format for in-depth manual or automated analysis.
Yet, if you’re all about privacy (same as we are), you can entirely disable the statistical data storage on our side. In this case, using webhooks will be the only available option for you to track the performance of your transactional emails.
