Unlimited Messaging

Unlimited Messaging sends WhatsApp messages, emails and SMS to your customers from your own accounts: your own WhatsApp number (linked by QR code), your own mailbox (IMAP/SMTP: Gmail or your domain) and your own Android phone (SMS from its SIM through a free open source app). One REST API request can go out on all three channels. There is no per-message billing: every plan, the free one included, sends unlimited messages. Paid plans (Medium 19 EUR/month, Max 29 EUR/month) remove the "Sent with UnlimitedMessaging.app" footer and add media, webhooks, higher throughput and support. Four ways to use it: a hosted MCP server (https://mcp.unlimitedmessaging.app) so Claude, ChatGPT or Cursor can send and read WhatsApp, email and SMS in plain words; a REST API with TypeScript and Python SDKs; an n8n community node; and a no-code web app with an inbox for replies. EU-hosted and GDPR-compliant. WhatsApp goes through a linked device on your normal account, not Meta's official Business API: no template approval and no per-message fee, but sending spam can get a number banned.

Aldea HQ

Aldea HQ is a community management platform built for organized communities of all kinds. HOAs and condo associations are the largest use case, and the same platform serves homeschool co-ops, clubs, self-managed neighborhoods, and small communities where enterprise tools are overkill. Volunteer boards typically run their community across WhatsApp groups, Facebook pages, spreadsheets, and email chains — where announcements get buried, documents get lost, and history disappears with board turnover. Aldea HQ replaces that sprawl with one platform: a community news feed for announcements (rich text, scheduling, featured posts), a structured digital handbook that keeps rules, policies, and governing documents searchable and current, a priority-based support ticket system with status tracking, and member management with role-based access and a current directory. An admin dashboard ties it together with activity tracking and community health at a glance. Aldea Pay is built into every plan at no extra subscription cost: collect recurring dues, send one-time payment requests for special assessments or events, target charges to specific member subsets, issue full or partial refunds, and send automated reminders to overdue members. Payments run on Stripe; the organization absorbs a 1–1.5% platform fee and members pay exactly the amount set — no surcharge at checkout. Every community gets its own branded subdomain. Setup takes about 15 minutes. Flat-rate pricing starts at $49/month, every feature on every plan tier's member limit, with a 14-day free trial and no credit card required.
