Is your server providing the maximum performance it can? It appears that there are some default registry settings that may occasionally prevent Emailtopia Response from accessing all the memory capcity that your server has to offer, adversely affecting the performance of the software.  If you have not yet received a call from Emailtopia Support concerning server memory access, please feel free to reach out to your account manager or to where we’ll be happy to talk you through checking (and  if necessary, updating) the relevant registry entries.
