Build vs buy
Do not own the pipeline.
Buy the router.
Agencies should not build Gmail or Outlook sending into Slack, Teams, Discord, Telegram, Google Chat, or Matrix. That stack is OAuth refresh, filter matching, destination formatting, and missed-ping support. Posthaste already filters, summarizes, routes, and exports an audit log for $19/month.
The comparison
Own the plumbing, or subscribe.
Build it
An in-house email router
- OAuth refresh for Gmail and Outlook
- Filter matching you have to keep current
- Destination formatting for Slack, Teams, Discord, Telegram, Google Chat, and Matrix
- A support queue for missed pings
Buy it
Posthaste Pro
- Connect Gmail or Outlook and write the filters
- Summarize what is worth interrupting a human for
- Route to Slack, Teams, Discord, Telegram, Google Chat, or Matrix
- Export the audit log as CSV or JSON
The product you would ship
A notifier is never just a notifier.
The first version is a Zap or a weekend script. The next is token refresh. Then filter syntax, six destination payloads, and a teammate asking why a ping missed Teams. That is not billable agency work.
Read Don't build your own email router if you are about to own that stack, or how agencies use Posthaste if you want the buyer path.
