I vibe-coded beehiiv, and it's 83% cheaper. ✨✨ Introducing MailCheap.ai ✨✨ Everything you need to run a newsletter... ✍️ Editor 📅 Scheduling 📈 Stats 🌐 A website for every issue 🛡️ Deliverability guardrails 🔗 Send from your own domain (and keep your reputation) And it's not a dinosaur tool: + It's open source; you can run it for free + It's agentic; everything in the UI is available to your AI Import from beehiiv, Substack, or Mailchimp in 2 minutes. You pay for the emails you send, not for dormant subscribers. From $19/month. Oh, and no "Powered By" badge at the bottom of your emails.

every week someone tells me they’re going to vibe-code their own @beehiiv alternative over the weekend. wishing them the best, here’s the backlog of things to make sure to include: > 99.3% email delivery rate (industry-leading) > team of deliverability experts with decades of experience > infrastructure to send 3M+ emails per minute > validating every single email submission (1st and 3rd party) > automated bot-detection to prevent spam signups > registering for every mailbox provider’s feedback program > ingesting data from said feedback loops and building suppression lists > tagging every email so gmail reports complaint rates per newsletter > classifying every bounce (hard, soft, mailbox full, DNS failure) and knowing which ones mean “try again” vs. “never again” > three layers of suppression: global, per-publication, and transactional > temporary suppressions that expire on their own, and permanent ones that never do > one-click unsubscribe, the way gmail and yahoo now require it > warming new IPs and domains on a schedule > watching blocklists around the clock, and pulling an IP from rotation the moment it’s listed > retrying deferred mail for 24+ hours before calling it a bounce > blocking disposable, invalid, and typo’d addresses before they ever reach the list > rate limiting every signup endpoint a bot can find > filtering bot clicks out of every report (something we pay an ungodly amount of money for) > an acquisition source on every subscriber > engagement history for every reader, across every post > multiple sender addresses for different emails > custom domain configuration that is aligned with DKIM, SPF, DMARC > a true WYSIWYG editor: what you write is what lands in the inbox, with no HTML required > turning that editor into table-based, inline-styled email HTML that holds up in outlook > real-time collaborative editing, so the whole team can work on the same issue at once > dynamic content: different sections for different readers, all in a single send > separate email and web versions of every post, from one draft > free and premium versions of the same post, split by a paywall break > merge tags that personalize every email, and a simulated subscriber to preview them before you send > templates with saved colors, fonts, and spacing, plus a default style for every post > columns, tables, buttons, blockquotes, sections, file attachments, and a table of contents with anchor links > native embeds for X, youtube, tiktok, instagram, bluesky, stocktwits, and podcast episodes > polls, referral blocks, recommendations, and ad slots, built right into the post > an AI writer, AI images, and a built-in AI agent one keyboard shortcut away > images resized and optimized automatically, however they’re uploaded > a live email-size gauge that warns you before gmail clips your newsletter > custom HTML blocks, cleaned so a stray script tag can’t break your post > automatically hiding anything an inbox can’t handle (video, iframes, audio) in the email version, while keeping it on the web > links and embeds made clickable even in outlook, which ignores links wrapped around tables > vertical alignment in columns, because a layout that looks off by 4px looks broken to readers > converting your newsletter to audio versions for readers who prefer to listen > random cohort sends to randomly split your list to test different content and conversion > slash commands: type “/” and insert any block without touching a menu > markdown and keyboard shortcuts for people who never want to touch a mouse > pasting from google docs with the formatting intact > search and replace across the whole post > comment threads right in the draft, so editors and writers stop living in google docs > footnotes and citations that work in the inbox and on the web > code blocks, for the technical newsletters > an AI writer that rewrites, translates, and fixes spelling and grammar in place > autosave, so a closed tab never costs you a draft > subject line A/B testing, built into the send flow > drag-and-drop images, from your computer, your media library, or a URL > rich-text image captions, plus image titles and alt text for accessibility > audio files that play inline > file attachments, so a PDF can ride along with the issue > sections with their own backgrounds, borders, and spacing > blockquotes with custom borders, colors, and styles > content breaks and dividers that render cleanly in every inbox > a REST API for subscribers, posts, segments, automations, and more > a send API to create and send newsletters programmatically > creating, updating, and deleting subscribers in real time > reading and writing custom fields on any subscriber > tagging subscribers from your own app > enrolling subscribers into automations via API > pulling opens, clicks, and engagement for every post > fetching post HTML rendered for free vs. premium, email vs. web > creating posts from a template, then appending or prepending content > fetching segments and every subscriber in them > managing tiers and premium subscriptions > pulling referral program data and milestones > reading poll and survey responses > pagination that holds up across millions of records > rate limits that protect the platform without blocking real integrations > API keys you can create and revoke anytime > an MCP server so claude, chatgpt, and other AI tools can work inside beehiiv > drafting and editing posts from an AI chat > asking for open rates, CTR, and revenue in plain english > comparing performance across dozens of posts in one request > looking up any subscriber's full history and engagement > building segments by describing them > creating and editing automations > generating AI images straight into your media
