Customer Reviews

FAQ

Sure! At UniOne, we provide two ways to integrate our API for email marketing with your existing CRM or e-commerce platform: SMTP and Web API.

SMTP API is a faster way to set up if your e-commerce platform or CRM system supports this type of integration (in certain cases, you may need to install an SMTP plugin).

However, creating integration through the Web (HTTP) API will give you more flexibility and sending speed, so it’s a better option for potential growth even if it requires some programming effort.

Of course, you can!

Scheduling emails through the UniOne API is possible for any time within the next 24 hours. You only need to specify the UTC date and time in “YYYY-MM-DD hh:mm:ss” format in your email-send API request.

As for the automated messages, you can set up any specific trigger scenario when your software sends the API request to UniOne based on certain criteria within your system.

As a self-hosted email service provider, UniOne is maintained by a team of more than 70 experts of various specializations. Our admins take care of the server infrastructure making sure it can process the sending workload at maximum speed.
