Before getting a plan with Brevo I saw their Trustpilot account, which clearly had most fake reviews and many bad reviews (very consistent), so I didn't had high expectations. We are using Klaviyo for years, but we wanted to try something cheaper and Brevo clearly is way better priced, especially for those with huge lists. We uploaded our contacts and then launched our first campaign and then we got our account deactivated. I understand that they are monitoring Unsubscribes rates etc, but for our first campaign it was 0.2% which is totally okay on Klaviyo and other platforms, so I dont recommend it to anyone. Their Emails come from France server and I assume their Ip is pretty damaged considering their cheap prices. Pay more for Klaviyo but you'll know that you get way better service. On top of everything you have to wait for years to get a response from support. We are asking for refund, but no response yet.
