MailUp: User reviews & features

MailUp is the Italian anchor of our catalog: an email marketing platform with SMTP sending whose measured demand is led by Italy. The company is now owned by TeamSystem S.p.A. (no longer Growens), with the brand and domain unchanged — mailup.com served the product homepage directly when we verified it in August 2026. Pricing at our normalization volumes has not yet been captured, so no price level is assigned; the entry will be updated when the pricing capture cycle reaches tier-2 services.

Scored 0–100 from public evidence: an official MCP server weighs most (40, +5 when hosted), then official agent skills, AI assistant apps, AI-friendly docs and built-in AI features. "Not found" means we couldn't locate it on MailUp's public pages or the official MCP registry, not that it can't exist. This is context, never part of the Deliverability Score.
