Account & plans
What is SendFox and how does it work?
SendFox is an affordable, easy email marketing tool for creators and small businesses. You can build contact lists, create and send newsletters, run automated email sequences, and grow your audience with forms and Smart Pages — without the complexity of bigger platforms.
Full guides: SendFox’s key features and how to set up your account.
How do I set up and access my account?
Sign up with your email address (or Google), confirm your details, and add your contacts. Log in at sendfox.com/login. If you can’t get in, use Forgot Your Password? to reset, or try a different browser or an incognito window. If you originally signed up with Google, request a password reset to switch to email/password login.

How do I change my account email address?
Go to Settings → Profile, enter the new address, and click Save changes. SendFox sends a confirmation link to the new address — click it while you’re logged in to SendFox to finish.

How do I upgrade, downgrade, or cancel?
You can upgrade inside SendFox: a Free account can buy Pro directly, with no lifetime deal needed, or get the one-time $29 Lifetime deal — click Upgrade in the top menu to compare them. To cancel a monthly Pro subscription, go to Settings → Plan & billing; cancellation takes effect at the end of the current billing cycle.
Full guides: how to upgrade or downgrade your plan and how to cancel or get a refund.
What plans and limits does SendFox have?
SendFox offers a Free plan (1,000 contacts and 3,000 emails a month, with 1 Smart Page, 1 form, 1 automation, and 3 lists), a one-time Lifetime deal ($29, 5,000 contacts), and a monthly Pro subscription that scales as you grow (up to 250,000 contacts on the top tier, with Enterprise offering custom limits). Pricing is intentionally low — Pro starts at $19/month. To raise your contact limit, upgrade your plan. Older lifetime accounts that send more than their one-time purchase covers are asked to move to a Pro tier to keep sending — see why an account gets paused or restricted.

Lists & contacts
How do I create a list and import contacts?
Create a list under Contacts → Lists, then open the list’s ⋮ menu and choose Import contacts to upload a CSV, paste contacts, or import them from MailChimp, Kit or Google. Use a clean, verified CSV of people who willingly subscribed, and remove invalid addresses first. SendFox has no one-click “merge lists” — export the lists, combine them into a single CSV, and import that into a new list.
Full guides: how to create a list and upload contacts, upload a CSV to an existing list, and switching from Mailchimp.
How do I edit and organize my contacts?
Go to Contacts, find the contact, open its row menu, and choose Edit contact to update their name, email and custom fields. To change their lists, open the contact and click Edit next to Lists. You can filter by status or engagement and act on many contacts at once with the checkboxes.
You can also put tags on contacts — colored labels like bought-course-a that group people without moving them into a separate list. Tag one contact, a whole selection at once, or everyone who signs up through a form or arrives in an import; then filter by a tag (or by Untagged), and send to or skip a tag when you build an email. Available on every plan.

What do contact statuses mean, and how do I handle bounces and invalids?
Contacts show as Engaged, New, Inactive, Unconfirmed, Unsubscribed, Bounced, or Invalid. Campaigns go only to subscribed contacts — and, with double opt-in on (the default), only confirmed ones; bounced, invalid, and unsubscribed contacts are skipped. Keep your list healthy: verify addresses with an email-verification service before importing and remove bounced or inactive contacts regularly, since a poorly kept list draws spam complaints, which can trigger account Optimization.
Full guides: what SendFox contact types and statuses mean and what “Optimized” means on your SendFox emails.
If I upload duplicates, will I be charged for them twice?
No — SendFox de-duplicates by email address, so re-importing a contact updates the existing record instead of creating a new one. Duplicates don’t count twice toward your contact limit.
Full guide: does SendFox create duplicate contacts when I upload a list?
How do unsubscribe and resubscribe work?
Unsubscribed contacts stop receiving campaigns. They can resubscribe themselves by filling in one of your forms again (they’re resubscribed to that form’s lists), and you can also move a contact back to subscribed from their contact record. With per-list unsubscribe on (Settings → List defaults → Enable per-list unsubscribe; new accounts have it on), subscribers can leave just some of your lists and keep the rest, and if you have two or more lists your emails also get a Manage preferences link.
Full guide: How do unsubscribing and resubscribing work in SendFox?
Creating & sending emails
How do I create, send, or schedule an email?
Go to Emails → Create email, pick your lists under To, write your subject and content, then preview, send a test, and choose Send now, or Schedule for later and pick a day and time. If you have a Smart Page, the send window’s Web step can also put the email on it — see how to publish an email to the web. Validate your domain first so emails send from your own address.
Full guide: how to create and send an email
Why didn’t my email go to everyone?
Usually one of four things: the Engaged only box was checked, your list has unconfirmed contacts (skipped until they confirm while double opt-in is on), your account is in Optimization mode, or a list or tag was added to Skip. Unsubscribed, bounced, and invalid contacts are never sent to, and people who left a list aren’t reached through that list.
Full guide: why didn’t my email go to everyone on my list?
What is Optimization mode, and how do I avoid it?
SendFox “optimizes” an account automatically when its emails draw too many spam complaints, and SendFox’s team can also turn it on after reviewing your sending. While optimized, your emails go only to people who opened one in the last 90 days, to protect your sender reputation. To recover, clean your list with an email-verification service, remove invalid or inactive contacts, and email only people who explicitly opted in, then email support@sendfox.com to have your account reviewed — Optimization doesn’t switch off on its own.
Full guide: what does “Optimized” mean on my SendFox emails?
Can I resend an email to people who didn’t open it?
Yes — in Emails, open the ⋮ menu on a sent email and choose Resend to non-opens, or click Resend to non-opens on its report. SendFox sends the same email, with the same subject, to the contacts who didn’t open it.
Full guide: how to resend a SendFox email to non-opens
Can I send attachments?
Not on campaigns or automation emails — host the file (for example on Google Drive) and link to it with a button or link in your email. Transactional emails your app sends through the API can carry files (see transactional email below).
Full guide: can I attach a PDF or file to a SendFox email?
Can I personalize emails and make images clickable?
Yes. Type @ in the editor (or use merge tags like {{contact.first_name}}) to insert personalization, and set a fallback for contacts with no first name. To make an image clickable, select it and add a link URL.
Full guide: personalization tags
Can I edit the HTML of my email?
Edit HTML (at the top of the editor) edits the current email’s HTML on any plan. Pro also adds Code your own on the bottom toolbar for full document-level HTML. If you hand-code a full HTML email, include an unsubscribe link with {{unsubscribe_url}}.
Full guide: creating and sending an email
Can I translate automation emails to another language?
SendFox doesn’t auto-translate emails. Write each email in your chosen language (you can use an external translation tool) before adding it to the sequence.
Automations
How do automations work, and what if mine isn’t sending?
Automations send a timed sequence of emails when a contact triggers them (for example, joining a list). Build and finalize the whole sequence before you start it: an email you add later reaches only contacts who haven’t reached that point yet — anyone who already finished the series won’t get it — and editing a live automation applies silently. If an automation isn’t sending, check that contacts entered after it was set up, that your account isn’t optimized, and that your bounce rates are healthy.
Full guides: how do I create an automation in SendFox? and what happens when you change a running automation.
Forms & Smart Pages
How do I create and embed a signup form?
Create a form under Grow → All forms, then copy the embed code into a custom-HTML block on your site (make sure caching plugins or script-stripping don’t interfere). SendFox forms work with WordPress and most website builders.
Full guides: how do I create and embed a SendFox signup form? and integrating SendFox with WordPress.
Can I send subscribers to my own page after they sign up?
Yes — set a redirect URL on your form (available on every plan), and new subscribers go to your thank-you page after submitting.
Full guide: how do I create and embed a SendFox signup form?
How do I create a Smart Page or use a custom domain?
Every account starts with one Smart Page, a hosted signup page; edit it (or, on Lifetime and Pro, create more) under Grow → All Smart Pages. Your primary Smart Page answers at sendfox.com/yourname; on Pro you can also connect your own domain under Settings → Sending → Smart page domain. Choose which page is primary with Make primary.
Full guides: how to create a Smart Page and changing which Smart Page uses your URL.
Domains & deliverability
How do I validate my domain and change my From/Reply-To address?
Add your domain under Settings → Sending → Email domains and copy the three CNAME records SendFox gives you into your DNS (set them to “DNS only” if you use Cloudflare). Until you validate, emails send from mail@sendfoxmail.com; after validating, they send from your own address. You set the “From” address on each email, and replies go to that address.
Full guide: how do I validate my sending domain in SendFox?
How do I improve deliverability (for example, Gmail’s Primary tab)?
Validate your domain, keep a clean and engaged list, and send relevant content. Ask subscribers to add your address to their contacts and to move your emails to the Primary tab.
Full guide: why are my emails sent from mail@sendfoxmail.com?
Integrations & API
What integrations does SendFox support?
SendFox connects to WordPress, Zapier, and many other tools, plus a public API for custom integrations. Zapier needs a paid plan (Lifetime or Pro). The Free plan includes a limited set of API endpoints — reading your account, lists, campaigns and stats, adding and tagging contacts, and transactional email — and the full API comes with a paid plan.
Full guides: what integrations does SendFox have, and how do I connect them?, SendFox + WordPress, and Does SendFox have a Zapier app, and how do I connect it?
How do I use the SendFox API?
Create a personal access token under Settings → Connections → API tokens and send it as a Bearer token. The API is rate-limited (about 60 requests per minute; transactional email has its own limit of 5 requests a second and 300 a minute); exceeding it returns temporary errors. On Free, a call to an endpoint outside the limited set returns an error saying the endpoint requires a paid plan. If requests fail, check your token and the specific error code.

Can SendFox send emails from my app, like login codes and receipts?
Yes, with Transactional email (in beta): request access under More → Transactional. It works on every plan, and each address an email goes to counts toward your plan’s sends.

Sending policy & account types
What kinds of emails are allowed?
SendFox is for permission-based newsletters to people who opted in. Its terms require permission from everyone you email and rule out cold outreach, spammy affiliate emails and other spam; emails that consistently perform poorly can get an account suspended. Sticking to engaged, opted-in subscribers also keeps your account out of Optimization.

Does SendFox support multiple users or admin roles?
Yes, on Pro: invite teammates under Settings → Team. Each teammate signs in with their own login and switches into your account; security settings, the team, Plan & billing and API tokens stay with the account owner. There are no other admin roles.
Full guide: what features do I get with SendFox Pro?
Can SendFox generate personalized certificates?
No — SendFox is an email marketing platform, not a document or certificate generator.
