What features do I get with SendFox Pro?

SendFox Pro adds whitelabel sending, paid newsletters, team logins, the full HTML editor and higher limits. Start it from Upgrade! or Settings → Plan & billing.

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.

Anyone can subscribe to Pro — no lifetime deal is needed. On the Free plan, click Upgrade! in the top nav, pick a tier on the pricing page and click Start Pro. If you already have a Lifetime plan (including the one-time $29 Lifetime), open Settings → Plan & billing and choose a Pro tier there.

Previously called the "Empire Add-On." Pro is the new name for SendFox's monthly plan. Existing Empire subscriptions keep renewing as they are; new subscriptions are Pro tiers. If you are on Empire, you can switch to a Pro tier any time from Settings → Plan & billing.

Which features come with Pro?

Every Pro tier, from Pro 1 to Pro 5 and Enterprise, includes the same features (a Pro trial does too). Free and the one-time $29 Lifetime plan don't:

• Whitelabel — remove SendFox branding. Send emails with no SendFox footer branding. (Whitelabel is a 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.
• Team logins. Give teammates their own login to your account under Settings → Team. Everyone works in the same account; only you can change billing.
• Full HTML editor. Use Code your own to paste any template or hand-tune a whole email line by line. On Free and Lifetime you can still edit an email's HTML with Edit HTML.
• 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.)
• Separate sending pool. Pro accounts send from a pool of sending IP addresses kept apart from Free and Lifetime traffic.
• AI subject line suggestions. Generate subject-line ideas from your draft, 5 suggestions at a time, within a monthly allowance.
• A/B testing for automations. Split-test two versions of an automated email; SendFox divides the audience between them, 50/50 by default, and you can change the split.
• Full-color email-footer icons. Your connected social profiles show as icons in your email footer in each platform's official brand color. Free and Lifetime plans get clean black icons.
• Smart Page custom domain. Serve your Smart Pages from your own domain under Settings → Smart page domain. See how to change your primary Smart Page.
• Custom confirmation redirect. Send new contacts to your own page after they confirm, with Custom confirmation redirect URL under Settings → List defaults.

How much does each Pro tier cost?

Pick the tier that matches your audience size. Pricing is monthly:

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. The same goes for sending: if your lifetime deal already gives you a higher monthly send limit than your Pro tier, you keep the higher one, unless SendFox has asked your account to move to Pro (see Why is my SendFox account paused or restricted?), in which case your tier's limit applies.

Already a SendFox customer? Your current plan (a lifetime deal or a monthly subscription) stays until you choose a Pro tier, along with your contacts and your contact limit. See how to upgrade or downgrade your plan. Older lifetime accounts that send heavily may be asked to move to Pro — see Why is my SendFox account paused or restricted?.

Need more than Pro 5, or custom limits? Enterprise is available on a contact-sales basis with limits set for your account.

Can I pay for Pro annually?

Every Pro tier can be billed annually instead of monthly. You pay for ten months and get twelve — so Pro 1 is $190 a year instead of $228, Pro 2 is $390 instead of $468, and so on up the ladder.

It is the same plan with the same limits; only the billing cadence changes. Switch from Settings → Plan & billing: monthly subscribers get a Switch to annual button there, and annual subscribers get Switch to monthly. The change is scheduled, so nothing is charged today: annual billing starts at your next renewal, and monthly billing starts when your annual term ends. Existing subscriptions stay monthly until you choose to switch.

Can I connect an AI assistant to SendFox?

Pro includes the SendFox MCP server, which connects your account to an AI assistant such as Claude, ChatGPT, or Codex. You can then add and tag contacts, draft and send emails, build automations, and ask how a campaign performed — in plain English. Setup instructions and your connection URL are at sendfox.com/developer/mcp, and there is a step-by-step guide for each assistant.

This is a Pro and Empire feature, and it also works during a trial. It is separate from the REST API: a Lifetime plan includes API access but not the AI assistant connection.

How do I change or cancel 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; a downgrade starts at your next renewal — you keep your current send allowance until then, but the lower tier's contact limit applies right away. 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.

Not ready to cancel? You can pause your Pro subscription for up to three months instead, whether you pay monthly or annually. A pause is free and reversible: it starts at your next renewal date rather than today, you are not charged on that date, and sending switches off for the length of the pause while your contacts, lists, automations and stats stay exactly as they are. Come back early with Resume now at the same price. See pause instead of cancelling.

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 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, and your Empire subscription keeps renewing as it is. To move to a Pro tier, open Settings → Plan & billing and choose one.

One tier is marked "Recommended for you"

• If your account has been asked to move to Pro, Settings → Plan & billing marks the tier SendFox has calculated for you with a Recommended for you badge, based on your contact count and how much you sent over the previous 30 days.
• When that badge is present, checkout starts you on at least the recommended tier.
• The recommendation is recalculated as your contacts and sending change. Full detail: Why is my SendFox account paused or restricted?

Still stuck? Browse the SendFox Help Center or email support@sendfox.com with the tier you're on.

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 subscriptions keep renewing with their plan and label; new customers choose a Pro tier.

Does the $29 Lifetime plan include whitelabel?

No. Whitelabel (removing the SendFox footer) is a 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 take effect immediately with a prorated charge; downgrades start at your next renewal, and the lower contact limit applies right away.

Does Pro include the SendFox AI assistant connection?

Yes. Every Pro tier, and a Pro trial, can connect an AI assistant such as Claude or ChatGPT. A Lifetime plan includes the API but not the AI assistant connection.
