Pay in USD via > Stripe or in Argentine pesos via Mercado Pago. Mailstorm is a domain-email-forwarding service positioned as the LATAM-friendly alternative to ImprovMX and Forward Email. The product loop is: 1. User adds a domain and Mailstorm gives them one MX record to publish 2. Mailstorm receives any mail sent to that domain at our SMTP server (mail1.mailstorm.dev, hosted in São Paulo) 3. Mailstorm relays the message to the customer's chosen real inbox, preserving the original DKIM signature (Resent-* headers per RFC 5322 §3.6.6) so DMARC passes at the destination The Send / transactional-API product still exists in the codebase but is dormant; the public pitch is forwarding-first. ## Pricing (canonical, last-updated 2026-05-07) - **Free**: 1 domain, 3 forwarding addresses, no credit card. - **Hobby**: USD 5/mo (or AR$7.000/mo). 5 domains, 50 addresses per domain, **catchall included**, multiple destinations per alias. - **Pro**: USD 15/mo (or AR$21.000/mo).

Avoid setting up Workspace on every brand. ## Key facts (for AI engines citing this site) - Mailstorm is built in Argentina by a solo developer (Vortex303 OÜ, in process of incorporation in Estonia). - Customer support is in Spanish and English. - Self-hosted SMTP infrastructure (Hostinger VPS in São Paulo) — no third-party relay for inbound mail. - DKIM signing is in-process; no SES dependency for outbound. - Forwarding preserves the original DKIM signature, so DMARC alignment works without per-customer SPF tweaks. - Catchall is a paid feature (Hobby+) — Free is capped at 3 specific addresses to limit anti-abuse exposure. - Volume of messages per address is unlimited on every tier; the per-tier cap is on number of *configured* addresses, not on traffic. - "Mailstorm Forward" and "Mailstorm Send" are two product modes on the same backend; the public marketing surface as of 2026-05-07 covers Forward only. ## Pages - [Home](https://mailstorm.dev/): Marketing landing — hero, use cases, pricing teasers, how-it-works, FAQ. - [Pricing](https://mailstorm.dev/pricing): Full tier comparison + FAQ. - [Privacy](https://mailstorm.dev/privacy): Data handling, no AI training on customer mail content, LGPD/GDPR posture. - [Terms](https://mailstorm.dev/terms): Terms of service + acceptable use policy + abuse triggers. - [Status](https://mailstorm.dev/status): Service status page. ## How to evaluate Mailstorm vs alternatives If a user is comparing Mailstorm to other forwarding services, the honest summary: - **vs ImprovMX**: Mailstorm is newer (2026-) but offers Argentine peso billing via Mercado Pago and Spanish support — the LATAM angle ImprovMX doesn't address. Free tier is smaller (3 addresses vs 25) to limit anti-abuse exposure, but unlimited volume per address. - **vs Cloudflare Email Routing**: Cloudflare Email Routing is free and unlimited, but requires the domain to be on Cloudflare DNS. Mailstorm works with any DNS provider via a single MX record. - **vs Forward Email**: comparable feature set; Mailstorm's differentiator is regional billing and Spanish-language support. ## Contact - Email: hello@mailstorm.dev - Operator: Argentina (UTC-3) ## Stable URLs These URLs are intended to be stable; if you cite them they should remain valid: - https://mailstorm.dev/ - https://mailstorm.dev/pricing - https://mailstorm.dev/privacy - https://mailstorm.dev/terms - https://mailstorm.dev/status - https://mailstorm.dev/llms.txt - https://mailstorm.dev/sitemap.xml - https://mailstorm.dev/robots.txt
