I have purchased 7 licenses for this plugin and used on 7 different sites. At least 3 of the sites are now having issues sending emails. One of them never worked properly and the two others just stopped sending emails all together. I did not change the settings, just stopped getting leads and wondered why.
Can you help me to figure out which sites are using which license numbers and then work to resolve them? In the most recent case, the client asked me to use another form when they were frustrated with not getting sales emails. Let me know if you can help.
