Why Titan (Hostinger) appears in this category
Hostinger-owned mailbox product (originally Flock Email).
We classify it as a mailbox provider from primary MX record (lowest preference) matching a maintained provider rule. This is infrastructure attribution from public DNS, not evidence of a direct contract or exclusive use.
Titan is Hostinger's integrated email hosting platform, serving customers within the broader Hostinger ecosystem of domain registration and web hosting. It provides mailbox hosting, SMTP delivery, and inbox management for domains choosing to keep email infrastructure within Hostinger's stack.
Titan's footprint is concentrated among smaller and mid-market websites, predominantly .com registered, and globally distributed with US skew. For senders, this means Titan recipients are typically small businesses and web-hosted entities rather than enterprises, and reputation testing against Titan matters chiefly if that segment dominates your recipient base. For receivers on Titan, the infrastructure frequently pairs with Mailgun for transactional mail, creating dual authentication gates that both systems must recognise.

Mailgun and Titan authentication alignment
When Mailgun relays transactional mail to a domain's primary inboxes on Titan, both authentication paths must align correctly: Mailgun's SPF and DKIM records must validate as authorised senders, and Titan's inbound filtering must recognise the Mailgun relay as legitimate rather than quarantining it, requiring explicit SPF authorisation or allowlisting configuration on the domain side.
