01 postmark alternative
The best Postmark alternative for transactional and bulk email.
Postmark excels at transactional mail — but scaling volume, adding marketing sends, and paying for dedicated IPs adds up. SMTP-X bundles SMTP, API, bulk + transactional, and a dedicated IP from €39/month.
Why switch from Postmark to SMTP-X?
Postmark is built for developers sending transactional email. If you also send campaigns, need a dedicated IP without extra fees, or want live chat support, SMTP-X covers both transactional and bulk on one plan — with Message Streams to isolate each traffic type.
