I have unsubscribes in my dashboard but I don’t use the Mailrelay link. How is that possible?
First of all, note that mailings must always include a clearly visible, hassle-free unsubscribe link to comply with Spanish and international anti-spam regulations. However, even if you don’t use Mailrelay’s dynamic unsubscribe links (because you use your own on your portal, for example), unsubscribes may still appear in your dashboard, in the corresponding section under…

You are not receiving emails on your own corporate domain
This is a very common problem that many users report to us. It happens because many mail servers and anti-spam systems let you set up a rule so that any email arriving from the corporate domain is rejected if the sender’s IP is not that of the organization’s mail server or servers. It is similar…

When an IP exceeds its sending limit, every SMTP command will receive…
