01 about us
Dedicated SMTP infrastructure built for inbox placement.
SMTP-X helps businesses send transactional and bulk email through monitored dedicated IPs — with real-time analytics, free deliverability tools, and human support that includes setup help.
What is SMTP-X?
SMTP-X is a cloud SMTP relay service for transactional notifications, marketing campaigns, and high-volume bulk sending. Every paid plan includes at least one dedicated IP, deliverability correction, API access, and a monitoring dashboard — so your team focuses on content, not infrastructure.
Scale by adding IPs
Each dedicated IP adds monthly sending volume — from 100,000 emails at €39/month to unlimited custom contracts.
Free setup assistance
Support via phone, chat, and messenger includes help connecting SMTP or API credentials — Mon–Fri 07:30–16:30 GMT+2.
Why did we build SMTP-X?
Most teams outgrow Gmail and Yahoo daily limits, then struggle with shared IPs on budget ESPs. We built a volume-based SMTP service where dedicated IPs, multiple domains, and analytics are standard — not expensive add-ons.
Who uses SMTP-X?
SaaS products sending password resets, e-commerce stores with order confirmations, agencies running bulk campaigns, and platforms like MailWizz, Mautic, and Interspire that need reliable SMTP relay.
How is SMTP-X different?
Dedicated IPs included on paid tiers, no daily caps (monthly limits only), multiple domains on one IP at no extra cost, and free deliverability tools — Mail Tester, SMTP Test, DMARC, and DNS lookup.
Our team
SMTP-X is operated by SMTP-X LLC (Latvia) and SMTP-X Limited (Hong Kong). Our support and deliverability specialists help customers migrate from SendGrid, Postmark, Mailgun, and other providers.
