Compared a few options
Evaluated this against two competitors. Where it wins: the automation and it is genuinely easy to set up. Where it lags: pricing gets steep at scale. On balance the feature set — especially the onboarding — justifies the 4 stars for our use case.

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

Skeptical, then convinced
I went in skeptical — most tools in this space overpromise. It actually delivers on the integrations, and support is responsive caught me off guard. still, I'd recommend giving it a real trial.
