RunSMTP is the email deliverability partner for SaaS startups and software agencies. 98%+ inbox rate, dedicated IP from day one, and a real human expert — not a chatbot.
While SendGrid gives you a relay and a ticket queue, RunSMTP gives you a dedicated deliverability expert, proactive IP monitoring, and the peace of mind that your emails work — always.
The decision is made by CTOs, Lead Developers, and founders who find us on LinkedIn, Hacker News, GitHub, and Reddit.
Not a relay you configure yourself. A managed deliverability service that handles everything from IP warm-up to ISP monitoring.
The email market is dominated by large players with weak support. RunSMTP's opportunity: be the human, flexible alternative with real expertise.
