How do I upgrade or downgrade my SendFox plan?
Upgrade by clicking Upgrade! and picking a Pro tier; on Lifetime or Pro, use Settings → Plan & billing. Upgrades apply now; downgrades wait for your renewal.
How does upgrading work in SendFox?
SendFox has three plan types: the Free plan, a one-time $29 Lifetime deal, and the monthly Pro subscription (Pro 1 through Pro 5, plus Enterprise). Upgrading means moving up that ladder — to a Lifetime deal, or to Pro for higher limits and the full set of Pro features.
Free and Lifetime accounts can move to Pro (Pro 1–Pro 5) at any time, Pro accounts can switch tiers or billing cycle themselves, and Enterprise changes go through support@sendfox.com.
You don’t need a lifetime deal first: on the Free plan, click Upgrade! in the top navigation, choose a Pro tier on the pricing page, and click Start Pro.
The monthly plan is Pro. (Pro is the new name for what used to be the "Empire Add-On". Existing Empire subscriptions keep renewing as they are, and you can switch to a Pro tier any time from Settings → Plan & billing.)
Already have a lifetime deal? Upgrade to Pro
The older AppSumo lifetime tiers are no longer sold, so you can't buy or upgrade to a higher lifetime tier. To add capacity or unlock the Pro features, subscribe to Pro instead.
Your lifetime deal stays exactly as you purchased it. Subscribing to Pro is additive — it adds the Pro features (whitelabel, paid newsletters, the full HTML editor, optional single opt-in, VIP sending) on top of your account, and your existing contacts are unaffected. Your limits are a floor, not a ceiling: if your lifetime deals already give you more contacts or monthly sends than your Pro tier includes, you keep the higher limit. The exception is an account that has been asked to move to Pro under the profitability requirement (see below) — it gets its Pro tier’s limits.
Sending works differently. Older lifetime deals were sold with uncapped sending, and that is no longer the case: once an account has sent more than its one-time purchase covers, a Pro tier is required to keep sending. If your account has reached that point, SendFox recommends a specific Pro tier based on your contacts and recent sending, and marks it Recommended for you. If your account shows a Recommended tier, checkout starts you on at least that tier. The recommendation is recalculated from your contacts and recent sending. See Why is my SendFox account paused or restricted?.
To subscribe, open Settings → Plan & billing and click Subscribe to on the Pro tier you want (for example, Subscribe to Pro 2).

How do I switch between Pro tiers?
Once you're on Pro, you can move up or down a tier at any time:
- Open Settings → Plan & billing.
- Click Switch to the tier you want.
- Review the proration summary, then click Confirm switch.
How the change is billed:
- Upgrading to a higher tier takes effect immediately, with a prorated charge for the rest of your current billing period.
- Downgrading to a lower tier is scheduled for your next renewal. You keep your current tier’s send allowance until then, but new contacts are limited to the lower tier’s contact limit straight away. Changed your mind? Click Keep with your current tier’s name (for example, Keep Pro 3) on the same page before the renewal date.
Before you confirm, the switch dialog shows what you’ll be charged today and your next renewal date.
Can I switch between monthly and annual billing?
Separately from changing tier, you can change how often you are billed. On Settings → Plan & billing, use the Switch to annual button — or Switch to monthly if you are already billed annually. Annual charges ten months and gives you twelve, so it works out at two months free.
The Switch billing cycle panel shows how much you save over a year before you confirm. Nothing is charged today: annual billing starts at your next renewal, and monthly billing starts when your annual term ends. Until then you can click Keep monthly billing (or Keep annual billing) to cancel the switch. Your tier, contacts, and sending limits are unaffected — this changes the cadence only.

How do I downgrade or cancel Pro?
To move to a lower Pro tier, use Switch to above (it takes effect at your next renewal). To stop Pro entirely, you can cancel at any time — see how to cancel or refund. Cancelling keeps your account and contacts; you return to your Free or Lifetime plan at the end of the billing period you've paid for. Changed your mind after cancelling? Switching to a higher tier also resumes your subscription, so it renews instead of ending.
Troubleshooting
I can't find a higher lifetime tier to buy
- That's expected — the older AppSumo lifetime tiers are no longer sold. Upgrade to Pro for higher limits instead.
It won't let me downgrade
- A downgrade is blocked if your current contact count is higher than the lower tier allows. Reduce your contacts first, or pick a tier that covers them.
- If you cancelled and your plan is winding down, the lower tiers show Resume before downgrading — resume your subscription first, then schedule the downgrade.
- Still stuck? Browse the SendFox Help Center or email support@sendfox.com.
Frequently asked questions
If I subscribe to Pro, do I lose my lifetime deal?
No. Your lifetime deal stays on your account. Pro is additive — it adds the Pro features, and where your lifetime deal already gives you a higher limit, you keep the higher one (unless your account is under the profitability requirement).
Can I still upgrade my AppSumo lifetime tier?
No. The older lifetime tiers aren't sold anymore. To grow, subscribe to Pro (Pro 1 through Pro 5), or contact sales for Enterprise.
Will I be charged right away when I upgrade a Pro tier?
Yes — upgrading is immediate, with a prorated charge for the rest of your billing period. Downgrading is scheduled for your next renewal instead.
