You built your app with Create.xyz because you wanted to go from prompt to product fast. The platform scaffolds frontend, backend, and database for MVPs. At $19/month, Create.xyz is built for validation. Now you need email that supports that validation phase without breaking the bank.

Create.xyz is for MVPs. You are testing ideas, finding product-market fit, iterating quickly. Your email platform should support this with generous free tiers and easy migration when you scale. Do not lock in to expensive tooling before you have validated your idea.

This guide covers 11 email marketing tools with strong free tiers for Create.xyz projects. I prioritized platforms that let you validate cheaply, then scale when needed. If you are using a different vibe-coding tool, check out our guides for Replit, Lovable, or Glide.

Validation Strategy

Start free

Use Sequenzy's 100 subscribers or EmailOctopus's 2,500 to validate your email strategy. Test sequences, measure conversions.

Upgrade when validated

Once you have product-market fit, upgrade to paid tiers. Sequenzy's $19/mo for 1,000 subs is reasonable.

Track what matters

Revenue attribution (Sequenzy) or conversion tracking shows which emails actually work. Do not scale what does not convert.

The Bottom Line

For Create.xyz MVPs, Sequenzy lets you validate with full features on the free tier. When ready, $19/mo scales to 1,000 subscribers.

For maximum free subscribers, EmailOctopus (2,500). For landing pages, MailerLite.
