If I add more subscribers later, what happens?
If you add more subscribers than your plan allows, here's what happens — and how to add more contacts or sending capacity with SendFox's Lifetime and Pro plans.
If you grow past your plan's limits
Your SendFox plan has a contact limit and a sending allowance. Here's what happens as your audience grows, and how to add more capacity when you need it.
Already a SendFox customer? The limits described here apply to new accounts. If you already have a plan (a lifetime deal or a monthly subscription), you keep it, including your current sending. The new limits only apply if you choose to switch.
Adding more contacts
The $29 Lifetime plan includes 5,000 contacts. If you need more, move to a monthly Pro plan (Pro 1 through Pro 5). On Pro, your contact limit is a floor, not a ceiling — if you already hold lifetime deals worth more contacts than your Pro tier, you keep your higher count.

Adding more sending
The $29 Lifetime plan includes a one-time pool of 300,000 emails that never refreshes. When that pool runs low or is used up, upgrade to a monthly Pro plan for a fresh monthly sending allowance. Your contacts and account stay intact — only sending pauses until you add capacity.
Existing AppSumo & lifetime customers
If you already hold a SendFox or AppSumo lifetime deal, you keep your existing plan and uncapped sending. The contact and send limits on the new plans apply to new accounts only.
Troubleshooting
Will I be charged automatically if I go over my limit?
- No. SendFox no longer adds automatic per-contact overage charges. To add capacity, you choose and subscribe to a Pro tier yourself.
I've hit my limit — what do I do?
- Open Pricing (or click Upgrade! in the top navigation) and choose a Pro tier that fits your audience.

Frequently asked questions
Am I auto-charged $10 for every 1,000 contacts I add?
No. That older overage pricing is no longer used. To add contacts, upgrade to a monthly Pro plan.
How do I add more contacts or sending?
Upgrade to a monthly Pro plan (Pro 1 through Pro 5), which raises both your contact limit and your monthly sending allowance. Enterprise is available for larger needs.
I already have a lifetime deal — do the new limits apply to me?
No. Existing lifetime-deal holders keep their plan and current sending. The new contact and send limits apply to new accounts.
