Which should you choose?

Choose Kit if

You sell digital products or a paid newsletter to your list
Visual automations and sequences run most of your email

You have a large free list and mail it often

Choose Unitpost if

Your app sends receipts, resets and alerts to the same people who read your newsletter
You want a REST API, SMTP and an MCP server on every plan
You want SMS on the same contacts, API key and bill
You'd rather pay for what you send than for the size of your list

What Kit does well

Creator commerce on every plan: digital products, paid newsletters and subscriptions
Visual automations and email sequences that creators build without code
Unlimited landing pages and forms, free plan included
A free plan for up to 10,000 subscribers, plus recommendations and sponsorships to grow the list

Unitpost: 5,000 emails/month, 200/day, no credit card; On paid plans your monthly price is a sending allowance you spend at your tier's rate, and it refreshes every month. Marketing and unlimited contacts are included rather than billed as add-ons.
Kit: Up to 10,000 subscribers; Paid plans (Creator and Pro) are priced by subscriber count and move up a tier as the list grows. Sales of products and paid newsletters carry a 3.5% + 30¢ transaction fee on every plan, card processing included.

How do I migrate from Kit?

Paste a Kit API key into the Migration Assistant (it only reads with it) and it previews what it can bring across before anything is written. Kit keeps sending the whole time, so there is no gap in delivery.

Imports: contacts, unsubscribes and consent, suppressions (bounces and complaints), tags. Partly imports: templates, sending domains, webhooks. Rebuild: segments, topics, api keys. Stays behind: send history and analytics, automations, forms, landing pages and commerce.

Frequently asked questions

Is Unitpost a Kit alternative?

For a newsletter that is part of a product, yes: one API and one contact list for product email and the newsletter, with SMS on paid plans. For creators who sell through Kit or run on its visual automations, Kit is the better tool. Unitpost has no commerce, no hosted forms, and its automations are in early access.

Can I import my Kit subscribers into Unitpost?

Yes, with a Kit V4 API key. The Migration Assistant brings subscribers with their state and custom fields, tags as segments, bounces and complaints as suppressions, and drafts, recent broadcasts and sequence emails as templates with Kit's Liquid placeholders converted. Unconfirmed subscribers are left out, and Kit segments arrive as names only because Kit's API doesn't say who is in them.

Can Unitpost sell my paid newsletter?

No. Unitpost doesn't bill readers. Keep products and paid subscriptions in Kit or your payment tool, and send to paying readers from a segment.
