Resend reaches 100,000 paying customers amid AI-driven adoption
Resend crossed 100,000 paying customers in October 2026, attributing significant growth to AI model recommendations. The company is expanding its infrastructure to own its email sending pipeline and improve deliverability.
Resend reported crossing 100,000 paying customers in October 2026, up from a total user base of 3 million. The company attributes a significant portion of its recent growth to AI models like Claude and OpenAI recommending Resend to users, a shift from the previous year when low-code tools like Lovable, Bolt, and V0 drove signups. Resend maintains a free tier of 3,000 emails per month with a daily cap of 100 emails to balance acquisition with abuse prevention, a strategy founder Zeno Rocha defends as essential for enabling developers in emerging markets.
The fully remote team of 45 is currently hiring for email-specific roles, including a deliverability expert from MailChimp. Resend is expanding its infrastructure by moving away from Amazon SES to owning its own email sending infrastructure, aiming to improve deliverability and control over the sending pipeline. The company is also exploring adjacent markets like SMS and WhatsApp but has prioritized deepening its email capabilities, including a new inbound email feature that allows users to receive and parse emails for automation. Rocha believes that Resend's focus on developer experience and "boring" infrastructure has positioned it to capture market share from legacy providers like Twilio and SendGrid, particularly as AI agents become the primary interface for software services.
