Mailrelay
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.
Deliverability: not yet tested. Placement figures on this site come exclusively from our own seed-list tests (how we test); once Mailrelay completes a cycle, its score joins the email deliverability ranking.
