Affordable email marketing for creators

SendFox was built by the team behind AppSumo, who watched creators and small businesses pay more for email marketing every month as their lists grew, while using only a fraction of the features they were paying for.

They built SendFox in 2018 to strip email marketing down to what actually grows an audience: newsletters, automations, signup forms, and landing pages, at a price a side project can afford.

With SendFox, users write and schedule campaigns, set up welcome and drip sequences that run on their own, and grow their lists with hosted landing pages, embeddable forms, and a built-in referral widget. RSS feeds and Smart Campaigns can turn new blog posts into newsletters automatically, and the documented API connects to Zapier and AI assistants like ChatGPT and Claude.

Today, more than 195,000 creators, bloggers, podcasters, and small businesses have sent over 2 billion emails with SendFox, keeping email the channel they own without a bill that grows with their list.

Introducing the NEW SendFox tier!

What's up, Sumo-lings! 👋

Over the past eight years, we've made SendFox into the simplest, most affordable email marketing tool for 150,000+ bloggers, podcasters, authors, and other content creators.

And every month, we're grateful that 35,000,000+ emails are sent from SendFox with best-in-class deliverability: "High" rating on ALL sending IPs and the default sending domain. 💪

Even though we're eight years in, we're not stopping.

Over the past six months alone, we've shipped 147 new features, improvements, and updates:

AI subject line suggestions
Template Gallery + Section Gallery
A/B testing in automations
Contact Activity Timeline + enhanced search
Faster page loading

As we continue to build and improve SendFox, we're also working to simplify the pricing.

Introducing the NEW SendFox Lifetime plan 🕺:

Just $29 one-time cost — pay once, and get it forever
5,000 contact limit with 300,000 lifetime sends
Unlimited automations, Smart Pages, and forms
API + Agent ready (Claude, Claude Code, ChatGPT, Codex, and more)
Smart Page gallery access

Plus, the Lifetime plan still has the AppSumo best-in-class 60-day refund guarantee. Try it for two full months, and if it's not the right fit, refund it and get all your money back.

And as you grow, we have new Pro monthly plans that you can check out on our site.

These monthly plans give you a monthly sending allotment that refreshes every month, white label (no branding), paid newsletter ability, optional double opt-in, a full HTML editor, and more... for a fraction of the cost of competitors.

If you have any questions, go ahead and leave them as a comment. We'll be happy to answer.

Who can use SendFox?

Hey, Sumo-lings!

We're getting some questions about what types of emails are NOT allowed under SendFox...

👎 Low-quality affiliate emails and offers. If you have purchased an email list, scraped an email list, "borrowed" an email list and you're blasting affiliate offers to tons of different products... SendFox isn't right for you. The truth is that Gmail HATES affiliate emails — so much so that they have an entire section of their bulk sender guidelines to avoiding affiliate emails: https://support.google.com/mail/answer/81126?hl=en. Gmail will spam, spam, spam bad affiliate offers all day. So if you want to send FOMO emails to your list with big bold "click here for this special offer!" text that links directly to a ClickFunnels landing page with an auto-play video? Don't use SendFox.

👎 Cold outreach emails. SendFox legally cannot do cold outreach emails. Cold outreach emails need to be done via very specific cold outreach tools — like AppSumo deals Lemlist or Reply.io. Doing prospecting, or manual sales outreach? Don't use SendFox.

On the other hand...

👍 If you're a content creator — blogger, YouTuber, podcaster, influencer — who is just starting out, or you have an email list already, SendFox IS designed for you! We can help you turn your audience into subscribers using our Smart Pages (aka landing pages) and forms for your site, and then we can help you communicate with your audience with our emails, automations, and Smart Campaigns.

We're the #1 tool to help content creators grow their audience. And with big-name content creators like Ryan Holiday, Shane Snow, YouTube channel "Yoga with Adriene", and 100,000+ other users... we can't wait to help YOU!
