Mailrelay: User reviews & features

Mailrelay is the Spanish anchor among our tier-2 services: an email marketing platform with SMTP sending whose measured demand is led by Spain, with a meaningful additional share from Latin America. mailrelay.com served the product homepage directly (landing on its English variant) when we verified it in August 2026. Its pricing at our normalization volumes has not yet been captured, so the entry carries no price level for now; the capture is queued with the rest of the tier-2 cycle.

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 Mailrelay's public pages or the official MCP registry, not that it can't exist. This is context, never part of the Deliverability Score.
