why is sending email more expensive than hosting

AFAIK resend and agentmail are AWS SES wrappers, is it really that complicated? They use ses tenant api, monitor stats for poor behavior/spam, setup notifications for thresholds, and pause/rectify bad actors with a task or lambda based on the notification.

AgentMail Review 2026: Pricing, Features and Verdict - InboxKit

# AgentMail Review 2026 ... AgentMail is an email inbox API for AI agents: it lets developers create programmatic inboxes so software agents can send, receive, and act on email in real time. ... This review summarizes what AgentMail is, its published usage-based pricing, what we could and could not independently verify, and why teams shopping for cold-outreach mailboxes should weigh the category difference before evaluating it. ... This review is based on publicly available information as of the publication date, including the AgentMail website (agentmail.to), its pricing page, its documentation, and its funding-announcement blog post, plus secondary coverage from TechCrunch, a GlobeNewswire release, Y Combinator's company page, Product Hunt, and the Hacker News launch thread. ... A scope note: AgentMail is not an email outreach product, and it is not marketed as one. Because this site covers email infrastructure, this review assesses AgentMail on its own merits as an agent email API and then explains, in plain terms, why it is a different category from the mailbox providers emailers usually compare. The editorial rating reflects AgentMail as an agent email API, not as a cold-outreach mailbox provider. ... AgentMail positions itself as "the email inbox API for AI agents." ... For an email operation, the relevant requirements are warmed, isolated sending domains and real-time deliverability monitoring, none of which is AgentMail's purpose. ... As an email inbox API for AI agents, AgentMail is a strong, credible product. ... The rating carries a hard category caveat: AgentMail is not email infrastructure and is not marketed as such, so it should not be evaluated as a mailbox provider for outreach. The score reflects AgentMail as an agent email API, not as a cold-outreach tool. ... Is AgentMail good for email? No. AgentMail is an email inbox API for AI agents (two-way, agentic and transactional email), and it is not marketed as an email outreach product.
