Avoid this serious mistake

Business owners should be cautious. We’ve used this service for nearly 8 years on their highest plans. Each year, several times, issues arise: sending errors, API downtime, automations failing, and more. Our team often has to identify problems and reach out for support. The outcome? Terrible response times (over a week), constant turnover of agents, and no willingness to investigate internal issues. Don’t be lured by the low prices; it will cost you much more in time and lost revenue due to unstable service, poor communication, and minimal support, even on top-tier plans. We're now investing thousands to switch providers, which I believe will be our best decision after all these years.
