Deploy useSend in one click installation.
Open-source email sending infrastructure — self-host your transactional and marketing email platform.
What you can build with useSend
useSend is an open-source alternative to Resend, SendGrid, and Postmark that lets you own your entire email sending stack. Built on Next.js with AWS SES as the delivery backend, it provides a clean REST API and SMTP gateway for both transactional and marketing emails — without per-email fees or vendor lock-in.
Self-hosting useSend on your VPS puts your sending domains, subscriber lists, and email analytics entirely under your control. You get a unified dashboard for monitoring deliverability, managing domains, handling bounces and webhooks, and scheduling campaigns — all from infrastructure you own.
Key features of useSend
REST API & SMTP
Send emails via a developer-friendly REST API or standard SMTP — drop-in compatible with existing applications and email libraries.
Delivery analytics
Track delivered, opened, clicked, and bounced emails in real time with a built-in analytics dashboard.
Domain management
Add and verify custom sending domains with DNS record guidance, keeping email reputation tied to your own infrastructure.
Scheduled sending
Queue emails for future delivery using the Schedule API, enabling drip campaigns and time-zone-aware transactional flows.
Webhook events
Receive real-time delivery events — bounces, complaints, opens, and clicks — via configurable webhooks for downstream processing.

I'm incredibly happy with Hostinger's VPS hosting! Their uptime is consistently top-notch, keeping my site running smoothly. Whenever I've needed help, their technical support team has been quick, knowledgeable, and genuinely helpful.
Everything is smooth and great with Hostinger, the AI chat bot + human chat, if AI can't resolve your question. Oh and them VPS is just fire, no ups and downs. Thank you dev team and everyone else involved. Keep it up 🚀
Finally a VPS hosting company that does it right! Well-priced. Excellent portal that respects their users' time. Seamless backups. Good support. Reliable. Feels rock-solid.
I reached out to Hostinger support after losing access to my self-hosted n8n instance, and I couldn’t be more impressed. Hostinger Agent and Mohammad from the support team were incredibly patient and thorough.
Many thanks to Carla for helping me with this N8N upgrade on my Hostinger VPS. Professional and knowledgeable, thank you again Carla.
Hostinger VPS is absolutely outstanding. It just always works. It is always fast and stable. Never down, never crashes.
The company is doing well, I am very happy with the specific services I use through them. Not as expensive as some places with really great VPS set ups and price plans.
