"Efficiency in Email delivery"
4.5/5
What do you like best about Email API?

One thing I really appreciate about Netcore Email API is that it gives us good control over our email operations without making things too complicated. The inbox delivery is quite consistent, which is important for transactional emails. I also find the real-time tracking useful when we want to quickly check delivery or engagement. The integration was smooth on our side, and the overall platform feels secure and stable for regular business use. Review collected by and hosted on G2.com.

What do you dislike about Email API?

The product is working well for our requirements, but the dashboard and overall UI could be made a little more intuitive. Some options are not immediately easy to find, especially for a new user, so it takes some time to get familiar with the platform. A cleaner navigation and simpler layout would make the day-to-day experience much easier. The support team is helpful, but ideally the interface should be simple enough that we don't need support for basic navigation. Review collected by and hosted on G2.com.

"Increase Email Engagement"
4.5/5
What do you like best about Email API?

One thing I have found useful with Netcore Email API is how easily it fits into our existing applications without requiring too much development effort. The API documentation is clear, and the support team is quick to help whenever we get stuck. I also like the visibility into email performance and the suggestions around email content, which help us improve engagement and deliverability. Overall, it gives us good flexibility while keeping the email-sending process simple to manage. Review collected by and hosted on G2.com.

What do you dislike about Email API?

Overall, Email API already covers most of the features we need for our day-to-day requirements. One area that could make it even better would be more detailed reporting and analytics, especially for tracking delivery, bounces and engagement in a simpler way. It would make monitoring email performance easier without having to check multiple sections in the dashboard. Review collected by and hosted on G2.com.

"Powerful transaction email with Dedicated IP"
5/5
What do you like best about Email API?

The overall experience with Netcore Email API has been quite smooth, especially for sending transactional emails at scale. I like that it gives useful insights into email reputation instead of just showing delivery numbers. The dedicated IP option is also a plus when there is a need for better control over sending reputation, and the pricing makes it practical for regular business use. Another thing I appreciate is that the platform is simple enough to manage without making the email setup unnecessarily complicated. Review collected by and hosted on G2.com.

What do you dislike about Email API?

The main area I feel can be improved is the dashboard experience. After logging in, it would be better if the important information and key metrics were presented in a more clean and clutter-free way. A simpler layout would make it easier to quickly find the required reports and monitor email performance. Apart from this, the overall service has been very useful and reliable for our requirements.

One thing I really like about Netcore Email API (formerly Pepipost) is that it continues to be a reliable email solution for businesses. The API integration is quite easy and the documentation makes the setup process smooth. I also find the 24x7 customer support very helpful whenever we face any issue or need quick assistance.

One improvement I would like to see is a daily transaction summary report over email. It would be helpful to get a quick overview of the email transactions, delivery status, failures, etc. without having to log in and check the dashboard every day. Review collected by and hosted on G2.com.

"Review for Netcore"
3.5/5
What do you like best about Email API?

Email deliverability is the one of Netcore strongest place.

We uses netcore API to sending Bulk email campaigns. Easy to integrate the text and html template in email campaigning through netcore API.

We love the email campaign builder feature, which allows for easy creation of responsive mailers through a simple drag-and-drop interface That's really good. Review collected by and hosted on G2.com.

What do you dislike about Email API?

Once the journey is live making edits can be difficult. Often, we have to stop the entire journey and create a new version to make the changes.

low loading times when uploading large datasets or processing heavy segmentation files.

Base processing will take little much time thats the thing we doesnt like.

The billing process is awful. If your card expires, you receive a bill without any instructions on how to resolve it. When you message customer support via chat, you receive no assistance. Review collected by and hosted on G2.com.
