Filters at every receiving provider mean that a well-crafted campaign can still be quarantined or rejected, so deliverability has to be managed alongside content. DuoCircle's Outbound SMTP service authenticates with DKIM signing and SPF validation, is backwards-compatible with printers, copiers, applications, and email clients, and routes through outbound mail server clusters in major geographic zones. It manages IP reputation on the sender's behalf, supports relay over ports 25, 587, 2525, and 10025 when an ISP blocks the default, offers TLS encryption end to end, can still deliver from IPs on RBLs or blacklists, and runs commercial anti-spam and outbreak detection to defend reputation if the sender's network is compromised by malware. Real-time reporting and tracking are available at every plan level with 24/7 chat, phone, and email support.
