Years in this space

I've evaluated a lot of these over the years. What stands out here is the dashboard — handled better than most — and the value for money is strong. Worth the time if this is your use case.

Does the job

Pretty happy overall. The core workflow just works and it is genuinely easy to set up. but no dealbreakers — I'd recommend it to a friend without hesitating.

Use it every day

Honestly didn't expect to like it this much. The integrations is exactly what I needed, and support is responsive. but I reach for it almost every day now and it just clicks.

I've evaluated a lot of these over the years. What stands out here is the automation — handled better than most — and it saves real time. The docs could be deeper is my one real gripe. Worth the time if this is your use case.
