Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
3.0
GPA, above 55 of the 57 other email marketing and newsletter tools we grade
SendFox is an email marketing tool aimed at creators and small newsletter publishers. It covers a drag-and-drop email editor, hosted signup pages and forms, automations and a list that can be sold as a paid newsletter through Stripe. Besides monthly Pro plans it sells a one-time Lifetime deal through AppSumo.
To get you started, here are 9 things to know about SendFox, taken from its own pages and our grades.
You build lists, forms and automations yourself.
- 1
Best for small creators on a budget, even one-time
Free and Lifetime both keep SendFox branding on your emails.
- 2
Paid plans start at $19 a month
As its pricing page puts it: $19 per month for up to 5,000 contacts, billed monthly.
- 3
There is a free plan
1,000 contacts and 3,000 sends a month, with 1 smart page, 1 form and 1 automation. SendFox branding stays on emails.
- 4
It runs on Web
Web.
- 5
Drag-and-drop email editor
Emails are built in a visual editor with merge tags and test sends, and Pro adds a full HTML editor.
- 6
Smart pages and forms
SendFox hosts landing pages and embeddable signup forms, so a list can be started without a separate website.
- 7
Automations and smart campaigns
Welcome sequences run when someone joins, and smart campaigns turn new posts from a connected blog feed into scheduled newsletters.
- 8
A 3.0 GPA, above 55 of 57
That is against the other email marketing and newsletter tools we grade, on value, the free plan, features, ease of use and platforms.
- 9
Keep it
To replace SendFox you would be making newsletters sent to thousands of people that still reach the inbox. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for small creators on a budget, even one-time
SendFox is a simple email tool with a free plan for 1,000 contacts, a Pro plan at $19 a month and a one-time Lifetime deal at $29 through AppSumo. Free and Lifetime both keep SendFox branding on your emails. Pro is the only plan that removes it.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | The $29 one-time Lifetime deal for 5,000 contacts and 300,000 sends is under a year of this category's $15 middle price. Pro is $19 a month at 5,000 contacts, rising to $79 at 50,000. |
| Free plan and trial | B | A free plan for 1,000 contacts and 3,000 sends a month, with 1 automation, 1 form and 1 smart page, no card needed. SendFox branding stays on emails. |
| Features | B | Drag-and-drop editor, smart pages and forms, automations, paid newsletters through Stripe, an AI writer and a transactional email API. The limits are on the free plan, not the core job. |
| Ease of use | C | A web app with no rating on record. You build lists, forms and automations yourself. |
| Platforms and integrations | B | Web only, with Stripe and Resend, and an API with MCP access. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who SendFox is for
- Fits if you are a small creator who wants one payment instead of a subscription
- Works for lists under 5,000 contacts, where the Lifetime plan applies
Who it is not for
- Tight if you stay free: 3,000 sends a month, 1 automation, 1 form and a SendFox badge
- Watch out: Lifetime comes through AppSumo with 300,000 sends in total, and a footer stays
- Pricey if your list grows: Pro is $79 a month at 50,000 contacts and $399 at 250,000
- Skip it if you want branding gone without paying: only Pro removes it
- Not for you if you want a phone or desktop app, as it is web only
Good to know
Good for
- Creators and newsletter writers starting a list on a small budget
- People who prefer paying once for a capped number of sends
- Small lists that fit inside the free plan's 1,000 contacts
Worth knowing
- SendFox branding appears on Free emails and a smaller footer stays on Lifetime; only Pro removes it.
- Free allows 1 automation, 1 smart page and 1 form; unlimited automations need Lifetime or Pro.
- Lifetime covers 5,000 contacts and 300,000 sends in total, and is bought through AppSumo.
- Pro steps billed monthly: $39 at 15,000 contacts, $79 at 50,000, $149 at 100,000, $399 at 250,000; above that is sold through sales.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace SendFox you would be making newsletters sent to thousands of people that still reach the inbox. That is not a weekend's work, with an AI app builder or without one.
It is one of the better ones too: its GPA of 3.0 is higher than 55 of the 57 other email marketing and newsletter tools we grade. It costs $228 a year.
What you could make
- Paid newsletters: an app builder makes this well.
What you could not
- Newsletters sent to thousands of people that still reach the inbox.
- Email sent in volume that still reaches the inbox.
- Mail servers with a good name among inbox providers.
- AI features, unless you pay a model provider for each request yourself.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. SendFox’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
