Distribute company announcements and track read status

Send organisation-wide announcements via Gmail API and capture read receipts per recipient, without relying on unreliable user-managed read confirmations.

The problem

Critical updates need confirmation that every user received and read them, but manual read receipts are ignored or misreported. Traditional mail-merge tools lack audit trails and cannot verify actual message opens.

How it works

  1. Generate and send individualised announcement emails to all users using the delegated service account.
  2. Embed a unique tracking pixel or link per recipient to capture actual opens.
  3. Monitor the recipient mailboxes for incoming read receipts or pixel loads using Gmail API.
  4. Aggregate read status for compliance reporting.

What changes

You get a per-user log of who has received and opened the announcement, with timestamps, without relying on users to manually confirm.

The trap in this one. Gmail API will not surface read receipts generated by client-side actions unless the user's mail client sends them, which most modern clients suppress by default. Tracking pixel loads are blocked by Gmail’s image proxy, so you may see false negatives where a user has read the mail but no open is recorded. Do not assume the absence of a receipt equals unread — you need to design for partial observability and communicate limitations to stakeholders.

Questions people ask

Can I force Gmail to send or acknowledge read receipts?

No. Gmail does not guarantee read receipts, and most clients suppress or ignore them automatically. The best you can do is track opens via embedded images or links, but this is not foolproof.

Can I resend only to people who haven't read it?

You can, but expect some false positives due to tracking limitations. Always provide a manual override for disputed cases.
