ConvertKitSendFox: the founder's playbook

ConvertKit is the gold standard for creator email marketing — but at $29/month for 1,000 subscribers, you pay a steep premium for features most creators never use. SendFox gives you smart campaigns, automations, and landing pages for a one-time $49.

Why switch in the first place

ConvertKit costs you money every month for software that's effectively the same as SendFox. SendFox gives you the same workflow with a one-time payment, so the savings compound over the years instead of going straight to the vendor.

The math: If you're paying $29/mo for ConvertKit, that's $299/year you could be keeping. SendFox LTD pays for itself in months, then saves you money forever.

The migration steps

1

Audit your ConvertKit account thoroughly

Before exporting anything, map out what you actually use in ConvertKit. Log into ConvertKit and document: (1) all Forms (name, embed type — inline, modal, slide-in — and where each is embedded on your site); (2) all Sequences (name, number of emails, trigger); (3) all Broadcasts sent in the last 6 months (subject lines, segments sent to); (4) all Tags (name and how each is applied — manually, by form, by sequence completion); (5) all Segments (filter logic). This audit takes 20–30 minutes and is the difference between a smooth migration and discovering a broken form three weeks later.

2

Purchase SendFox LTD and configure your account

The SendFox lifetime deal ($49) is available through GrabLTD. After purchase, activate your account at sendfox.com. In Account Settings, add your sending from name and from email address. SendFox sends from your own email domain — connect it by verifying your domain (Settings → Domains → Add Domain). SendFox will give you a CNAME or TXT record to add in your DNS for domain verification. Also add a DKIM record if you want your emails to arrive authenticated (Settings → Email Authentication). These DNS records are the same ones you would set up for any email tool — if you have them set for ConvertKit, check if you need to add SendFox's specific records.

3

Export your subscribers from ConvertKit

In ConvertKit, go to Subscribers → All Subscribers → Export as CSV. This downloads a CSV with columns for email address, first name, tags, and any custom fields you have added. If you have multiple segments you want to keep separate, also export each segment individually (Subscribers → Segments → select segment → Export). Pay attention to unsubscribed contacts: ConvertKit marks them with status 'Cancelled'. Import these as unsubscribed in SendFox to honour the opt-out — sending to unsubscribed contacts is both illegal and damages your sender reputation.

4

Import contacts into SendFox and set up your lists

SendFox organises contacts into Lists (similar to ConvertKit's Tags). Before importing, create a List for each major ConvertKit Tag or Segment you want to preserve. In SendFox, go to People → Lists → Create List. Then go to People → Import → Upload CSV. Map the CSV columns to SendFox fields: Email, First Name (SendFox uses First Name for personalisation as {{first_name}}). Assign the imported contacts to the appropriate List during import. For contacts with multiple ConvertKit tags, you will need to import the CSV multiple times (once per list), or export a single unified list and manually re-tag in SendFox's bulk-action UI.

5

Rebuild your signup forms and landing pages

ConvertKit forms are either inline (embedded in a page), modal (popup), or slide-in. In SendFox, go to Forms → Create Form. SendFox forms are simpler — single-field (email only) or dual-field (first name + email) embedded forms with a customisable CTA. For each ConvertKit form: create the equivalent in SendFox, copy the embed code, and replace the ConvertKit embed code on your site. SendFox also has a built-in landing page builder (Pages) — for any ConvertKit landing pages (hosted at pages.convertkit.com/...), recreate them in SendFox's Pages feature and update any links pointing to the old ConvertKit URL.

6

Rebuild your email sequences

ConvertKit Sequences map directly to SendFox Automations. In SendFox, go to Automations → Create Automation → Select: 'When someone subscribes to a list, send this series of emails.' Add each email from your ConvertKit sequence with the same delay (Day 0, Day 3, Day 7, etc.). Copy the email content across — remembering to replace ConvertKit's merge tag syntax ({{ subscriber.first_name }}) with SendFox's syntax ({{first_name}}). For ConvertKit's more complex automations (if/else branching based on link clicks or tag changes), SendFox does not have an equivalent visual automation builder — simplify these to linear sequences or use a simple webhook + Pabbly Connect to handle conditional logic.

7

Test deliverability and check your from-email authentication

Send a test campaign to yourself and a few test addresses across Gmail, Outlook, and Apple Mail. Check: (1) arrives in inbox (not spam); (2) from name and email display correctly; (3) images load; (4) personalisation tags render correctly (first name shows actual name, not {{first_name}} placeholder); (5) unsubscribe link works and removes contact from the list; (6) click tracking works (if enabled). Use mail-tester.com to score your email setup — aim for 9+/10. If you land in spam, check your DKIM record in SendFox settings and verify your domain ownership is confirmed.

8

Replace all ConvertKit embeds and links, then cancel

Go through every place you have a ConvertKit form or link: your website (contact page, blog posts, resource pages, popup/modal scripts), your email signature, your social media bio, any guest posts or external sites where you embedded a ConvertKit form. Replace each with the SendFox equivalent. For embeddable forms, paste the new SendFox embed code. For ConvertKit hosted landing pages (pages.convertkit.com/...), these become inaccessible when you cancel — ensure all external links to them are updated to your new SendFox page URLs. After completing the link audit, cancel ConvertKit from Settings → Billing → Cancel Plan.

Gotchas we hit (so you don't)

SendFox lacks ConvertKit's visual automation builder

ConvertKit's Automations feature is a visual canvas where you connect triggers, actions, and conditions with a drag-and-drop interface. SendFox has sequence-based automations (send email X days after subscribing) but not ConvertKit's branching logic (e.g. 'if subscriber clicks link A, add tag B and send email C, else send email D'). If your ConvertKit automations use conditional branching, you will need to simplify them to linear sequences in SendFox, or handle branching logic externally via a webhook to Pabbly Connect.

SendFox has a monthly send limit of 12 campaigns per list

SendFox's LTD limits you to 12 campaign sends per list per month. For most newsletter creators who send weekly or bi-weekly, this is not a constraint (4–8 sends/month). For daily email senders or creators who run many separate lists, plan your campaign calendar carefully before purchasing. Sequences (automated drip emails) do not count toward this limit — only broadcast campaigns do.

ConvertKit's custom field data may not fully transfer

ConvertKit allows unlimited custom fields per subscriber (purchase date, last course completed, referral source, etc.). SendFox supports a smaller set of standard and custom fields. Before migrating, check which custom fields you actually use in personalisation, segmentation, or automation logic. Fields that only exist for historical tracking may not need to be migrated. Fields used in active personalization (e.g. {{course_name}} in a sequence email) must be mapped to SendFox custom fields and populated in the CSV import.

ConvertKit Commerce and tip jar do not exist in SendFox

ConvertKit has a native Creator Commerce feature for selling digital products, tip jars, and paid newsletters (Paid Newsletters via Stripe). SendFox has no equivalent. If you use ConvertKit Commerce, you will need an alternative: Gumroad, Lemon Squeezy, or ThriveCart (LTD available on GrabLTD) for product sales, and Stripe Payment Links for tip jars. This is a real gap — factor it in before switching if commerce is a meaningful part of your creator business.

Subscriber merge tags use different syntax

ConvertKit uses {{ subscriber.first_name }} syntax (double curly braces with 'subscriber.' prefix). SendFox uses {{first_name}} (no prefix). When copying email content from ConvertKit to SendFox, search for every {{ subscriber. and replace it with {{. Also check for custom field references: ConvertKit uses {{ subscriber.custom_field_name }} which maps to SendFox's {{custom_field_slug}}. A single missed merge tag that renders as literal text in a sent email is an embarrassing and easily avoidable mistake — do the find-and-replace before you import templates.

FAQ

Will I lose any subscribers during the migration?+
No — your subscriber data is exported from ConvertKit as a CSV and imported into SendFox. The only contacts that should not be contacted going forward are those marked as Unsubscribed or Bounced in ConvertKit, and you import these into SendFox with the corresponding status so they are correctly suppressed. No contacts are deleted in ConvertKit during the export process.
Does SendFox work well for newsletters? I mostly just send one email per week.+
Yes — this is exactly SendFox's primary use case. The platform was designed for individual creators who publish a regular newsletter. The Smart Campaigns feature automatically resends to non-openers with a tweaked subject line (a feature ConvertKit charges extra for on lower plans). For a weekly send to a list under 50,000, SendFox is well-suited.
Can I move my ConvertKit subscribers without them having to re-opt-in?+
Yes. You are migrating subscribers you already have a consent relationship with — you do not need them to opt in again. Import your ConvertKit CSV into SendFox directly. The legal basis for emailing them (their original opt-in consent) carries over. You do, however, need to honour all unsubscribes from ConvertKit — import unsubscribed contacts as suppressed in SendFox.
SendFox says 'unlimited contacts' but is there a catch?+
The $49 AppSumo LTD offers unlimited contacts, but SendFox does apply a monthly email send limit (12 campaigns per list per month on the base LTD tier). Sequences (automated drip emails triggered by subscription) are not counted in this limit. For a weekly newsletter that is 4 broadcasts/month — well within the limit. Verify current LTD terms on the purchase page, as AppSumo occasionally updates tier limits for new buyers.
What happens to my ConvertKit landing pages after I cancel?+
ConvertKit-hosted landing pages (at pages.convertkit.com/your-slug) stop working when your account is cancelled. If you have shared or linked to any ConvertKit landing pages (in social bios, guest post author boxes, past emails, etc.), update those links to your new SendFox page URLs before cancelling. SendFox has a Pages feature to recreate hosted landing pages — create each one and confirm the URL works before deactivating ConvertKit.
