According to Live Direct Marketing's daily Tranco top-1M scan (July 13, 2026), YMLP is the email service provider (ESP) for 151 domains — 0.02% of 617,702 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
YMLP is an email service provider offering organisations the ability to send email through its infrastructure via SMTP and SPF authentication. It operates as a separate platform from major cloud email providers.
YMLP's user base is concentrated among smaller and mid-market organisations distributed across many countries and top-level domains, particularly .com. It is frequently deployed in environments also running Microsoft 365. For anyone evaluating email deliverability or sender reputation, YMLP's position in the long tail of smaller sites means its infrastructure reputation is built on aggregate sending quality across its diverse customer base rather than anchored by dominant enterprise brands.

YMLP's position as a smaller ESP means its senders share infrastructure-level reputation. ISPs evaluate mail from YMLP's servers based on aggregate sending patterns and abuse history across all customers, not solely the sender's domain reputation. Deliverability for individual YMLP senders therefore depends partly on the platform's overall authentication and compliance posture.
