Many email services focus on either sending notifications or running marketing campaigns, but UniOne makes it possible to do both without needing separate services in case of a proper integration with your internal CRM system. This makes my work much simpler, as I can manage all client communications in one place. It saves time, reduces costs, and removes the need for multiple subscriptions. **What do you dislike about UniOne Email API?** One thing I dislike is the platform's interface design.

A fresher design would make the overall experience even better. **What problems is UniOne Email API solving and how is that benefiting you?** UniOne has solved the problem of switching between services for different types of email. Now, I can send important updates to clients and run promotional campaigns smoothly from one system. This all-in-one solution is very helpful for us and makes our processes much more efficient.

We’ve been using this service for several months now without encountering any delivery issues, despite our large user base and numerous recipients.

However, there are times when advice from the service is critical, and I received feedback from them quite quickly. **What do you dislike about UniOne Email API?** As for the cons, I can only mention some minor issues with the UI. They are more about aesthetics and don't affect the functionality of the service.

UniOne's pricing plans fit our volume of transactional email sends perfectly. There's no need to overpay other services when UniOne can do the job just as well, and even save you money. Our deliverability rates are high, everything is clear and transparent. UniOne complies with all GDPR requirements, which was a critical factor for us in choosing a service. I believe we will continue to use UniOne because we are pleased with both the cost and the service's reliability. **What do you dislike about UniOne Email API?** I always miss having more default email templates, not just with UniOne, but with other vendors as well.

Everything else works perfectly. **What problems is UniOne Email API solving and how is that benefiting you?** The service is a great fit for companies looking to optimize costs without sacrificing service quality.

They are always responsive and provide helpful solutions quickly. This level of support has been crucial in keeping our email operations running smoothly. " **What do you dislike about UniOne Email API?** Limited status reset for emails is the only drawback I can remember working with Unione. They retain the statuses of email addresses that are marked as undeliverable, unsubscribed, flagged as spam etc. While you can find these emails and reset their status to allow sending again, this can only be done 2 times per day per account. Although you can request to increase this limit by contacting UniOne support, it would be more convenient if the reset limit was higher by default. **What problems is UniOne Email API solving and how is that benefiting you?** UniOne Email API has provided us with a reliable, efficient, and high-performing email solution. ### 8.

Since our clients predominantly send triggered emails through their CRM systems, their primary concerns revolve around achieving high delivery rates and cost-effectiveness for smaller volumes. Consequently, we sought an SMTP connectivity solution and discovered UniOne, which appeared to be user-friendly, straightforward, and affordable.

While the availability of comprehensive user action data through webhooks is valuable and informative, we would also appreciate the ability to retrieve specific aggregated data through an API.
