SendPost Information

SendPost is the AI-powered email infrastructure for ESPs and high-volume senders who need real-time visibility and precise control over email deliverability. What you get: → Real-time visibility into every IP, domain, and sub-account, with live mailbox-provider response data and AI-driven health alerts → Precise routing and throttling per ISP and sender profile, so every send executes your rules → Automated IP and domain warmup — no spreadsheets, no manual configuration → Smart soft-bounce retry logic that learns and adapts per ISP → Centralized MTA rule management instead of configuring 20+ servers one by one → Blacklist and reputation monitoring across every tenant → Slack-native workflows and a deliverability-issue CRM that ties problems to root causes The outcome: your team moves from reactive firefighting to proactive deliverability and can scale sending without scaling headcount. Trusted by ESPs processing hundreds of millions of emails monthly. Our own email marketing platform SendX runs 300M+ emails/month on SendPost (we eat our own dog food!) and gets 95-95% delivery rate. If your team is fighting email blocklists, chasing inbox placement, or buried in vendor tickets, talk to us. We were built for this. → sendpost.io
