01 sendgrid alternative

The best SendGrid alternative for SMTP and API email at scale.

SendGrid is a popular ESP — but dedicated IPs cost extra, marketing and transactional infrastructure are split, and volume pricing climbs fast. SMTP-X includes a dedicated IP, bulk + transactional sending, and spam testing 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 SendGrid to SMTP-X?

If value for money, dedicated infrastructure, and combined transactional + marketing sends matter, SMTP-X is built for volume senders who want transparent EUR pricing and chat support — not tiered upsells for every feature.
