This program is full of errors and problems, do not purchase it. Pilot Group blame it on the server, and yet I have tried it on two servers that have other mailing systems on them and have no problems.
Purchasing this product from Pilot Group was a nightmare. From the sales process through to trying to get it to work it took three weeks, and still not resolved.
I now have different software for this purpose, which was installed in 15 minutes and it works percetly with no problems.
