Verdict
A newsletter sender that also handles a basic event RSVP page and posts a matching caption to one social account is a real weekend-to-week build — the SES/DNS deliverability setup is the same real work as any other newsletter tool, and the event and social pieces add genuine but bounded scope on top. What's missing is Constant Contact's actual differentiator: dozens of integrations and a polished, drag-and-drop editor tuned for small businesses running in-person events.
Exhibit A — The prompt
Received on31.07.2026Build a personal event-and-newsletter sender: campaigns through Amazon SES, a simple RSVP page, and a caption cross-posted to one social account. Stack: Next.js, PostgreSQL, Amazon SES, one social platform's posting API (pick one, e.g. Bluesky or Mastodon, which have simpler auth than Meta's).
Core loop: the newsletter half works like a standard SES-based sender — double opt-in subscribers, a Markdown composer, bounce/complaint webhook handling, a public archive. On top of that, the operator can create a simple event page (title, date, location, description) with an RSVP form that stores attendee name and email in the same subscriber database, and optionally send the same announcement as a short caption to one connected social account via its API.
Requires an AWS account with SES access and a verified sending domain, plus OAuth credentials for whichever single social platform is connected — cross-posting is disabled cleanly if that OAuth token isn't configured, with the newsletter and event-page features unaffected.
Do not build: ticketing or payment collection on the event page (that needs PCI-compliant payment handling, a separate scope entirely), posting to more than one social platform (each platform's API and auth model differs enough that "pick one" is the honest scope), or a drag-and-drop template editor — Markdown and a fixed event-page layout are enough.Opening prefills the prompt — press enter to run it.
Exhibit B — What you lose
- B.1 dozens of one-click integrations (POS systems, review platforms, scheduling tools)
- B.2 a drag-and-drop visual editor tuned for small-business templates
- B.3 posting to multiple social platforms at once instead of just one
- B.4 ticketing and payment collection built into the event page
- B.5 phone and chat support from people who've handled this exact small-business use case before
Prior art
Exhibit C — Why people still pay: deliverability, growth network, and integrations
People pay for Constant Contact because small businesses running real-world events want one place that handles the invite email, the RSVP list, and the social announcement without stitching three separate tools together — and want it to keep working without someone on staff maintaining the integration. The subscription buys that breadth and reliability, not just the sending infrastructure.
Questions
Can I import my existing Constant Contact contacts?
Constant Contact exports contacts to CSV with consent status, which imports cleanly. Past event RSVP lists export the same way, though social posting history doesn't transfer since it lives on the platform you posted to.
Will it work on my phone?
RSVPing to an event works fine from a phone browser. Composing campaigns and managing the social connection is a desktop-web task this build doesn't optimize for mobile.
What does it cost to run?
SES email is about $0.10 per 1,000 sends; the social API is free for the single-account posting volume a personal tool needs. Hosting runs a few dollars a month.
What's the one thing that doesn't survive the rebuild?
Breadth of integrations. Constant Contact connects to dozens of small-business tools — POS systems, review sites, scheduling apps — out of the box; this build picks one social platform and stops there, and adding each new integration is its own separate project.
