turboSMTP: Transactional relay
turboSMTP is a Transactional relay founded in 2009, headquartered in Italy. Pricing: EUR 14.95/mo (Basic). It targets Small and mid-volume senders who want a European supplier and reachable support. Our verdict: Human support on chat, ticket and phone, and no industry banned by name. Watch for: The free plan is a 6-month trial, and only the checkout page says so. Rated 6.2/10 overall across ease of use, deliverability, and pricing value.
What is turboSMTP?
turboSMTP has run since 2009 out of Milan, operated by an Italian company called Edisplay Srl, and it is still independently owned while its American counterparts have all been absorbed. Its canonical site is serversmtp.com and the relay answers at pro.turbo-smtp.com, with a separate European endpoint.
Two things set it apart. Prices are quoted in euros on an EU-region stack, and the free plan of 200 emails a day is valid only for the first six months, after which the entry plan costs 14.95 euros for 15,000 a month. On 7 May 2026 a fire at the NorthC data centre in Amsterdam took it offline; sending came back within 48 hours from Frankfurt.
