Blacklisted Emails (Poland) Hello,We are your clients and use several profiles, each of which is experiencing the same issue with receiving notifications when a booking is made. The problem is occurring more and more frequently, and in recent days it’s been happening daily, which significantly affects my work.I have contacted your support team via live chat multiple times, and I always receive the same excuses. I have now reached out to my domain host, and here is the response I received: Dear Sir/Madam, the issue lies with the sender’s server. It is currently listed on multiple external public blacklists:https://mxtoolbox.com/SuperTool.aspx?action=blacklist%3a149.72.200.43&run=toolpageOn our side, we cannot add an exception for such a server as it would expose our clients to spam from that source. This issue must be resolved by the sender by delisting their IP address from these public blacklists or by changing the IP address used for sending. This is not something we can fix on our end.Calendly’s servers ha
