- Decent voicemail quality
Cons:
- High failure rate in voicemail delivery

On G2
Rating: 5/5 (1 review)
With only ONE review on G2, it’s difficult to gauge overall customer sentiment. The reviewer praised the platform for its simplicity and cost-effectiveness but didn’t provide detailed feedback on performance.
Review authenticity:
It’s impossible to draw meaningful conclusions about the platform’s effectiveness with one review. While the sole reviewer gave a perfect rating, the lack of additional feedback makes it difficult to verify if this reflects the broader user experience.
Don’t invest in an RVM provider before…
Considering the following tips:
- Check multiple review platforms to ensure consistent user feedback.
- Look at the timing of reviews—sudden bursts of positive reviews can be a red flag.
- Research what people are saying on forums like Reddit for more unbiased opinions.
- Ask fellow business owners about their experiences with the service.
Ultimately, the best provider is one that will give your sales team a massive leg up and make the whole process a lot easier.
Slybroadcast is a solid option for RVM, but you can definitely find a better provider at the same price range.
