Limited international support, confusing, and no way to close your account **Rating:** 0.0/5.0 stars **Reviewed by:** Facturación H. | CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** May 06, 2026 **What do you like best about Synthflow?** Easy to use if you are in the United States. **What do you dislike about Synthflow?** **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. **What problems is Synthflow solving and how is that benefiting you?** Right now, none ### 2. Very bad experience **Rating:** 1.0/5.0 stars **Reviewed by:** Sofia V. | Principal Director, Mid-Market (51-1000 emp.) **Reviewed Date:** January 20, 2025 **What do you like best about Synthflow?** The concept is great and in a future I think will be a good option to create a good virtual agents **What do you dislike about Synthflow?** The agents have a lot of issues, sometimes don't do the activities and the conversations in some moments have a lot of problems, also give unreal information. The worst part is about the minutes in your plan, because at the end of the month you lose all your time, and this information is not clear in your plan (I was lose 95% of a PRO Plan) **What problems is Synthflow solving and how is that benefiting you?** AI Agents for task automation **Official Response from Jian Robedillo:** > Hi Sofia, Thank you for sharing your experience.
