According to Live Direct Marketing's daily Tranco top-1M scan (July 12, 2026), Smaily is the email service provider (ESP) for 187 domains — 0.03% of 617,244 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
Smaily is an email service provider that handles transactional and marketing mail delivery for websites and applications. Operated from Estonia, it functions as a multi-tenant platform, allowing customers to send messages through its shared infrastructure and relay mechanisms.
Across the web's largest sites, Smaily appears sparingly—concentrated instead in the long tail of smaller organisations, particularly those with domains registered in the .ee space. It commonly appears in SPF records alongside Microsoft 365, suggesting adoption by businesses combining Microsoft's productivity stack with Smaily's mail delivery. For email administrators managing inbound filtering or sender authentication, Smaily's footprint signals a regional and mid-market presence rather than deployment at enterprise scale.

As a multi-tenant ESP, Smaily customers share sending IP addresses. This means reputation at the IP layer is collective: if one customer sends spam, it can degrade deliverability for others on the same relay. Email systems evaluating Smaily-sourced messages see them originating from shared pools, so the sender's own domain reputation—established through SPF, DKIM, and DMARC alignment—becomes the primary differentiator. Proper authentication configuration is therefore essential when using Smaily to ensure your mail is assessed by your own sending record rather than the platform's aggregate reputation.
