When messaging around 1,000 people a day across multiple markets, Sonar's UI allowed me to keep track of where I was with onboarding numbers in each market I owned. It's reliability in delivering messages allowed me to keep a steady backlog of leads to lean on when necessary. Review collected by and hosted on G2.com.
The only thing that was frustrating was sometimes the ability to upload a CSV was broken and could often times remain that way for a long period. It was impossible to upload new leads to reach out too and could set back work by up to a day sometimes. We also struggled with international numbers using Sonar, they were usually slow to acquire an international number that would go through to Mexico and some EU markets.
