Pro plan features
SendFox Pro is the monthly plan — Pro 1 through Pro 5 plus Enterprise — that unlocks whitelabel sending, paid newsletters, the full HTML editor, and much higher sending limits.
What is SendFox Pro?
Pro is SendFox's monthly subscription. It comes in five tiers — Pro 1 through Pro 5 — plus a custom Enterprise option, so you can pick the contact and sending limits that fit your list. Every Pro tier includes the same Pro feature set; the higher tiers simply raise the caps.
Pro is a monthly upgrade on top of a SendFox Lifetime plan. If you're already on a paid Lifetime plan (including the one-time $29 Lifetime), open Settings → Plan & billing and choose a Pro tier to subscribe. If you're on the Free plan, get the $29 Lifetime plan first, then upgrade to Pro from Plan & billing.
Previously called the "Empire Add-On." Pro is the new name for SendFox's monthly plan. If you already subscribe to the Empire Add-On, nothing changes — you keep your plan and pricing until you choose to move to a Pro tier.
Pro features
These features are included with every Pro tier (and with a Pro trial). They are not available on the Free or one-time Lifetime plans:
- Whitelabel — remove SendFox branding. Send emails with no SendFox footer branding. (Whitelabel is a monthly Pro feature; the one-time $29 Lifetime plan keeps the small SendFox footer.)
- Paid newsletters. Charge your subscribers for premium content through your own connected Stripe account.
- Full HTML editor. Paste any template or hand-tune your campaigns line by line. Free and Lifetime plans use the basic editor.
- Optional single opt-in. Turn off double opt-in account-wide if you don't need it — your choice. (Lifetime accounts can also switch to single opt-in once they’ve validated a sending domain.)
- Dedicated, higher-reputation sending. Pro accounts send from SendFox's premium sending IP pool.
- AI subject line suggestions. Generate subject-line ideas from your draft — up to 100 generations a month, 5 suggestions each.
- A/B testing for automations. Split-test two versions of an automated email; SendFox sends each variant to half the audience.
Pro tiers & pricing
Pick the tier that matches your audience size. Pricing is monthly:
| Plan | Price | Contacts | Emails / month |
|---|---|---|---|
| Pro 1 | $19/mo | 5,000 | 100,000 |
| Pro 2 | $39/mo | 15,000 | 200,000 |
| Pro 3 | $79/mo | 50,000 | 400,000 |
| Pro 4 | $149/mo | 100,000 | 800,000 |
| Pro 5 | $399/mo | 250,000 | 2,000,000 |
| Enterprise | Custom — contact sales | Custom | Custom |
Your contact limit is a floor, not a ceiling. If you already hold lifetime deals that add up to more contacts than your Pro tier (for example 25,000 contacts) and you subscribe to Pro 1, you keep your higher contact count — Pro never lowers it.
Already a SendFox customer? These plans and limits are for new accounts. If you already have a plan (a lifetime deal or a monthly subscription), you keep it, including your current sending. The new tiers and limits apply only if you choose to switch.
Need more than Pro 5, or custom limits? Enterprise is available on a contact-sales basis with limits set for your account.
Changing or canceling Pro
You can change tiers at any time. Upgrading to a higher tier takes effect immediately with a prorated charge for the rest of your billing period; downgrading takes effect with your new, lower rate from the next invoice. You can also cancel your Pro subscription at any time — you'll keep Pro features until the end of the period you've paid for, then return to your Free or Lifetime plan.
Troubleshooting
I don't see the Pro features
- Pro features require an active Pro subscription (or an active trial). Confirm your subscription is active under Settings → Plan & billing.
- Whitelabel (no SendFox branding) is a monthly Pro feature — it is not included with the one-time $29 Lifetime plan.
I'm on the Empire Add-On — do I need to do anything?
- No. "Empire Add-On" is the previous name of the monthly plan. You keep your current plan and pricing until you choose to move to a Pro tier.
Frequently asked questions
Was the Empire Add-On discontinued?
No. The Empire Add-On is simply the previous name of SendFox's monthly plan, which is now presented as Pro (Pro 1–5 + Enterprise). Existing Empire customers keep their plan and label until they choose a Pro tier.
Does the $29 Lifetime plan include whitelabel?
No. Whitelabel (removing the SendFox footer) is a monthly Pro feature. The one-time $29 Lifetime plan keeps the small SendFox footer.
Can I switch between Pro tiers later?
Yes. You can move up or down a tier at any time. Upgrades are prorated immediately; downgrades apply your new rate from the next billing cycle.
Is the old $49 lifetime pricing still available?
No. The legacy $49-per-5,000-contacts lifetime ladder (and the old per-1,000-contact overage pricing) is no longer sold. Existing holders keep what they purchased (including their uncapped sending), and only new customers get the $29 Lifetime plan or a Pro tier.
