I have used this when this was known as WYSIJa ;).

Some pre-sales queries:

1. What would happen if I max out all the 5000 subscribers under my website? Does it mean that the emails won't be captured by the sign up form? What are my options to increase the subscriber count later (after the deal ends)?

2.I read somewhere that the campaign will be paused by you if the bounce rate is more than 10%. Sorry, couldn't find where I read that. Is that bounce rate (where the email is invalid)? Or some other parameter?

TIA!
