Gabonator68 Hi, who sets up my acymailin component on hosting, because for some shows on google.mail it reports this warning. see Attachment
mihha There are multiple things that you should do in order to prevent such things: implement DKIM, SPF and DMARC records warm up your IP address by sending gradually more and more emails. You should start with small batches (few emails per batch) and send more and more emails over the period of few weeks, even months in some cases avoid using cheap hosting companies because they tend to have a big fluctuation of their customers. Such customers get hosting just to send out spam emails and then move on to some other company. What they left is an IP address which has been flagged as spam source
