Transactional and bulk SMTP — high deliverability, simple pricing.
QueenSMTP is a managed SMTP relay for transactional and bulk email. Plug it into your app with standard SMTP credentials, or call our REST API. We handle IP warming, DKIM, SPF, DMARC, bounce processing, and deliverability monitoring — so your password resets, order confirmations, and newsletters actually reach the inbox.
