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 buy additional codes on AppSumo to send to the additional contacts. When you hit your current limit on an AppSumo plan, we'll display a banner inside your SendFox account to buy more vouchers.
- 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.
