While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more

To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more

Full blown email marketing system with training.

I am a retired senior in my 70's and was looking for a way to supplement my income on the internet. I felt that email marketing was the best way to proceed and I found SendOnyx. What I found was a complete email marketing system that most importantly has a full training program attached. The training program is very important to a beginner like me.

Sendonyx Is Very Easy to Use.
The support service is very good, response time is very quick and prompt. I get on with Adam, the main support, very well. Sendonyx is run by very professional people. This is my main autoresponder as there is no monthly fee to send out unlimited emails. I highly recommend Sendonyx.

Excellent All-in-One Email Marketing Tool – Highly Recommended!

I’ve been exploring different email marketing tools for quite some time, and honestly, SendOnyx has been a refreshing experience. What really stood out to me is that it combines everything in one place - from building landing pages to running email campaigns and even handling cold outreach. It saves both time and money by eliminating the need for multiple subscriptions.

The AI-powered features make campaign creation incredibly simple, even if you’re not very technical. I was able to set up campaigns, import leads, and get started without any hassle. The drag-and-drop builder and automation capabilities are especially useful for scaling outreach efficiently.

Another big advantage is that there are no recurring monthly fees, which is a huge relief compared to other tools in the market. It’s a great option for marketers, entrepreneurs, or anyone looking to build and manage their email list effectively.

Overall, SendOnyx delivers solid value and functionality. Definitely worth trying if you want an all-in-one, AI-driven marketing solution.
