AgentMail
agentmail.to ↗Email infrastructure for AI agents: create an inbox by API, send and receive, and let an agent act on structured messages.
AgentMail is an email API built for AI agents. An inbox is created with one API call, sending and receiving happen over REST, and every message arrives as structured data: threads, attachments, webhooks included. There is no IMAP scraping and no borrowed Gmail account; an agent gets what a human employee gets on day one, an address of its own.
The practical consequence is that email becomes a programmable surface. An agent can hold its own address, read what lands there as JSON, reply in thread, and trigger on webhooks instead of polling. Deliverability, parsing and threading are the provider's job; the application only handles logic.
The design encourages a clean division of responsibility: the provider owns delivery, parsing and threading, while the subscriber list, the opt-in logic and the data stay in the application, behind a thin adapter. Changing providers then means rewriting one file, not migrating a system. That portability is what earns it a place here.

A pivot is often just the polite word we use with investors when the first company is dead and we have decided to build another one. And that is fine. Not because failure is noble, but because luck needs exposure: every market you enter, every product you ship and every channel you test is one more surface where something unexpected can land.
Build articles
Replit alternatives fall into three lineages, and the useful move is to pick across them instead of inside one: browser IDEs that hand you a machine (GitHub Codespaces, CodeSandbox, Coder), agent builders that write the app for you (Lovable, Bolt, v0, Firebase Studio), and plain hosts that run whatever comes out (Vercel, Railway, Render, Fly.io).
D-RAG, in the AI sense, is Differentiable Retrieval-Augmented Generation: a method published at EMNLP 2025 that trains the retriever and the generator of a knowledge-graph question-answering system together, by letting the generator's answer loss flow back into the retriever. The other results for this query are a headwear spelling, a rapper, and a 2024 LinkedIn post that reused the acronym for something else.
Marketing articles
LinkedIn offers nine post formats: text, image (one or up to 20), video (one per post, up to 15 minutes), document (a PDF or slide file, up to 300 pages), poll (two to four options), celebration, event, article (125,000 characters) and newsletter. Pick one by the single action you want a reader to take in the feed: read, swipe, watch, vote or save. A reach ranking is the wrong reason.
To schedule a post on LinkedIn, open the composer, write the post, click the clock and choose a publication time. You can find the queue through that same clock under View all scheduled posts. Check the content, time zone and link preview before confirming. Scheduling helps organize publication; it does not, by itself, establish how much reach a post will receive.
