Mailchimp
The value is the network, the data or the infrastructure. Keep paying.
Sends bulk email to a subscriber list. It carries the whole path from a signup form to a delivered campaign: list management, segmentation, a drag-and-drop template editor, scheduled sends and the reporting afterwards — plus the sending infrastructure that decides whether any of it reaches an inbox.
Do not rebuild Mailchimp. Build the thin layer around a sending provider instead. STACK - Astro with a Node adapter, SQLite via better-sqlite3 - An SMTP or API relay — Amazon SES, Postmark or Resend - You are outsourcing deliverability on purpose, because it is the part you cannot build SUBSCRIBERS - Address, source, consent timestamp, confirmation token, unsubscribe token - Double opt-in, so consent is provable years later CAMPAIGNS - Composed in Markdown, rendered to table-based HTML with a plain-text alternative - Previewed in the browser before sending, at 320px and 600px - Sent in batches with a configurable rate limit, resumable if the process dies halfway BOUNCES AND COMPLAINTS - Provider webhooks writing to a suppression list that every future send consults - No way to bypass that list, ever UNSUBSCRIBE - One click, honouring both the List-Unsubscribe header and the link, effective immediately STATS - From provider webhooks only — no tracking pixel and no click-wrapping unless deliberately enabled Include a README on SPF, DKIM and DMARC records, and on warming a new sending domain, because that determines whether any of this works.
What you lose
- Deliverability: warmed sending IPs, established domain reputation, and relationships with the mailbox providers that decide whether you reach the inbox
- Feedback loops with ISPs and automatic complaint and bounce handling, which is what keeps you off blocklists
- Compliance machinery — consent records, one-click unsubscribe headers, suppression lists honoured across every campaign
- A template editor that survives Outlook, and rendering tested across dozens of clients
- Deliverability monitoring that tells you a problem exists before your open rate collapses
If you would rather not build
- MailerLite — paid, cheaper at small list sizes, same job

Why this verdict
our own opinion · changed only by a person
22/100
Verdict no at 22: the software is easy and the infrastructure is not. Deliverability is reputation built over years with mailbox providers, and no amount of correct code substitutes for it. The prompt therefore rebuilds the interface and rents the part that matters.
