01 mailgun alternative

The best Mailgun alternative for growing senders.

Mailgun is a developer-friendly ESP — but costs rise quickly at volume, dedicated IPs are add-ons, and support is email-only on lower tiers. SMTP-X offers SMTP + API, live chat, and a dedicated IP from €39/month.

Specification 03

IPv4 Dedicated pools. Domain-level reputation you control — not a shared neighbourhood.

Metrics Delivered, bounced, deferred as they happen. SMTP and API, same path.

Relay STARTTLS on 587, or the HTTP API. Transactional and bulk on one set of credentials.

Why switch from Mailgun?

Small and mid-size teams often outgrow Mailgun's pricing before they outgrow its features. SMTP-X targets the same developer audience with route parsing via webhooks, inbound forwarding, and transparent volume tiers — plus chat support on every paid plan.
