Easy to use if you are in the United States. Bewertung gesammelt von und auf G2.com gehostet.
**Phone number coverage is extremely limited.** Synthflow only offers numbers from the US, Canada, and Australia directly. There are no Spanish numbers — or for that matter, any other European numbers — available out of the box. For any European business trying to call local prospects, this is a deal-breaker. Calling Spanish customers from a +1 US number kills your answer rate before you even start.
**The Twilio workaround forces you onto the Business plan.** When I tried to connect my own Twilio account to use a proper local number, I discovered that this option is locked behind the Business tier — roughly four times the price of the Pro plan. There's no transparent disclosure of this limitation upfront; you only find out after committing time to building your agent.
**The new platform interface is a usability disaster.** The recent redesign is genuinely confusing. Basic actions that should take one click now require navigating multiple unintuitive menus. Settings are scattered, naming conventions are inconsistent, and the learning curve has gotten worse, not better.
**There is no way to close your account from the dashboard.** This is the most concerning issue. I've searched every settings menu, every account section, every billing page — there is literally no option to delete or close my account. This appears to be deliberate, and it's an unacceptable practice for any SaaS in 2026, especially under European GDPR rules where users have an explicit right to erasure.
