What platform does clarity use for autogenerated emails? Should we be building that content and have that setup within our app programming?

Do you have an idea of what kind of invalid emails you are receiving? That will help you determine which vendor is the best fit for you. For example do you consider support@, info@, or postmaster@ invalid, some vendors will weed those out for you? Or are you just concerned with making sure the email has an accurate Domain/MX Record? Will blocking SPAM IP addresses be enough to address your needs, if so you need a vendor who checks agains URI DNSBLs. With that in mind, here's a good blog article about the top vendors.

I haven't come across something that does exactly that. If it's a relatively small number of companies you refer, signing up to an affiliate program for each of them is probably easiest. If the number of brands/companies is bigger, this sounds like something that should be built. Would love to have a quick chat with you on that.

Git is the latest and coolest software, and SVN is the outdated old one. When you tell SVN that you want to create a new branch of your code to have some fun, it creates a heavy weight dumb carbon copy for you. But Git is intelligent, it won't create a new copy for you instead it will only keep track of the things you're adding/removing/changing with respect to the original sources. I hope I made the point, for more let's have a telephone call some time :)
