Kit vs Resend
Pricing
Kit: Free up to 10,000 subscribers, Creator from $39/mo ($33/mo billed yearly)
Resend: Free up to 3,000 emails/mo, then from $20/mo
Description
Kit: Email marketing (formerly ConvertKit) built for creators who want to grow an audience, not manage a CRM
Resend: Modern email API that developers actually enjoy using
Pros
- Visual automation builder that is actually understandable
- Free plan covers up to 10,000 subscribers with unlimited landing pages, forms and broadcasts
- Tagging system makes subscriber management simple and flexible
- 3,000 free emails/month, enough for most early-stage products
- Clean, simple API that takes minutes to integrate, not hours
- Built by the creator of React Email: the DX is noticeably better than SendGrid or SES
Cons
- Visual automations and email sequences need a paid plan
- Pricing climbs quickly as your list grows: Creator costs $89/mo at 5,000 subscribers
- Landing page builder is basic compared to dedicated tools
- Younger service: smaller ecosystem and fewer battle-tested edge cases
- No visual email template builder: you design emails in code (React Email)
- Deliverability is good but has not been tested at the same scale as Postmark or SendGrid
Details
Kit, known as ConvertKit until its rebrand, was built by Nathan Barry specifically for creators: bloggers, podcasters, course creators, and indie founders who need to grow an email list. It strips away the complexity of tools like Mailchimp and focuses on what actually matters: collecting subscribers, tagging them based on behavior, and sending the right emails at the right time.
The free plan goes a long way, with tagging, segmentation and unlimited broadcasts for up to 10,000 subscribers. The real value is in the visual automations and email sequences, which only come with paid plans. Emails are built in a template-based designer with 40+ templates. If you need pixel-perfect HTML emails, look at MailerLite or Beehiiv instead.
Resend is what happens when someone who hated the existing email APIs built a new one. Created by Zeno Rocha (who also built React Email), it focuses on developer experience above everything else. The API is clean, the docs are clear, and you can have transactional emails working in your app in about 15 minutes.
The free tier of 3,000 emails per month covers most solo founders for months. When you outgrow it, $20/month gets you 50,000 emails. If you value developer experience and clean code over the battle-tested reliability of Postmark or the scale of SendGrid, Resend is the pick.
