Swipe One feels like it could be the perfect fit for me and my needs. There are a few questions I have to make an informed decision:

1. If a user reaches their contact or email sending limits, are there overage fees? If so, how much will it cost for additional contact and additional email sends?

2. If LTD users outgrow their plan limits, are there any discounts applied to switching to a paid subscription or other upgrade options beyond the Appsumo campaign?

3. Who would you save are your direct competitors? This will help highlight the vision for Swipe One (at east in the short to medium term).

4. Does Swipe One support RSS for newsletter creation and auto sending?

5. Does Swipe One support broken link checks, blacklist domain checks, email validation, and span word/phrase checks?
