At high bulk volumes, a single SMTP easily gets throttled by providers, blocklisted, and sees bounces spike. Marketing Channels lets you connect multiple sending channels at once — SMTP / SendGrid / Mailgun / Alibaba Cloud DirectMail / AWS SES / Tencent Cloud SES — with weighted round-robin, failover and regional routing to maximize deliverability.
From channel onboarding to traffic scheduling to health monitoring, every step keeps deliverability rock-solid
SMTP / SendGrid / Mailgun / Alibaba Cloud DirectMail / AWS SES / Tencent Cloud SES / Postmark all built in
Distribute traffic by weight — primary channel 70% / backup 30% — to avoid blowing through any single channel's quota
Auto-select a channel by recipient location — Alibaba Cloud DirectMail domestically, SendGrid abroad — to maximize deliverability
When the primary channel errors, bounces spike or gets rate-limited, traffic switches to a backup automatically — no campaign interruption
Real-time monitoring of each channel's delivery rate / bounce rate / blocklist status — anomalies are visible immediately
Each channel automatically configures DKIM signing, SPF checks and DMARC policy for anti-spam-friendly scoring
Configure credentials once; per-channel quotas
Running your own SMTP used to mean buying IPs / getting whitelisted / configuring DKIM / chasing email reputation scores — fiddly and prone to drop rates. Marketing Channels connects directly to the industry's top mail providers, who've perfected IP reputation / anti-spam / delivery assurance — and you simply reuse it.
Traffic split by weight + health
At high send volumes, a single channel is easily bounced back by carriers. Smart routing auto-decides which channel each email takes across three dimensions — "weight + region + health" — switching instantly when the primary channel falters, so campaigns never stall.
Domestic users via Alibaba Cloud DirectMail, overseas via SendGrid / Mailgun — regional routing maxes out deliverability on both
Europe-US / Southeast Asia / Middle East each route to a localized mail provider to avoid being flagged as spam
Compliance mail goes through self-hosted SMTP, marketing mail through cloud services, and critical mail through a dedicated backup channel
Big-sale days send 10x the usual volume — multiple channels spread it so no single quota runs dry and disrupts the campaign
