If I add more subscribers later, what happens?

If you add more subscribers to your account later — whether from CSV upload, leads from forms or landing pages, or from integrations — you'll have to increase your contact limit size.

• If you bought SendFox on AppSumo, you'll have to upgrade to a higher Tier. When you hit your current limit on an AppSumo plan, we'll display a banner inside your SendFox account to upgrade - https://appsumo.com/products/sendfox/#appsumo-plans
• If you bought SendFox directly on our site, you'll be auto-upgraded $10 for every 1,000 subscribers you add above your current limit. In certain cases, like uploading a CSV that pushes you above your limit, you'll see a notice that you will be charged the increase. 
• If you have an active Lifetime License from AppSumo.com and exceeded your contact limit, SendFox will automatically charge you $10 for every 1,000 contacts your account requires.
• The fees mentioned above are one-time fees and are on an as-needed basis only. If your account does not exceed your contact limit, you will not be charged the one-time fee.
