About

SendPost replaces manual workarounds, messy hacks and daily frustrations that come along with your email API/SMTP provider. See if you are sending only a few thousand emails then most email API solutions work well. You will choose one of them based on price, features or support. The real problem comes if you are one of the big senders—sending millions of emails per month. That's when managing multiple sending domains, IP-Pools and IP/Domain reputation becomes a severe headache. At that scale, even a minor dip in your email open rate or deliverability impacts your revenue. You want a solution which helps you understand what broke with your email deliverability and how you can fix it quickly. You don't want to spend hours wading through logs and manually checking if your domain or IP is blacklisted or your sending reputation is low.

About

Sendmux gives AI agents their own inbox and a controlled way to send email. Each agent can receive messages, read threads, handle attachments, send replies, and react to new mail through signed webhooks or Server-Sent Events. Teams can send through Gmail OAuth, Outlook OAuth, SMTP providers, or managed Amazon SES. Sendmux can spread sending across providers with weighted routing, sender-domain routing, health checks, failover, and quotas by second, minute, hour, or day. Developers get Mailbox, Sending, and Management APIs, OpenAPI docs, SDKs, the sendmux CLI, MCP tools, and Sendmux Skills. The platform also covers tenant isolation, mailbox-scoped API keys, custom domains, logs, metrics, and usage-based pricing with no per-seat or per-mailbox fees.
