Microsoft Teams scheduler: schedule announcements into a channel

Send regular announcements into a Teams channel or chat without being there at the time. You create a Workflows webhook in Teams, paste its link in Postemi, and the message goes out as a card with text and an image at the time you set. Postemi only sends; it does not read the channel.

No Teams app to approve

A Workflows webhook is enough, created by you in Teams.

Only sends

Postemi cannot read the channel or its members.

The link stays secret

The webhook link is stored encrypted and never shown again.

One calendar

Teams sits next to your other channels, so nothing is planned twice.

Plan, schedule and measure your Microsoft Teams content from one place

Announcements with an image into a Teams channel or chat, scheduled ahead.

Commonquestions

I have an old incoming webhook link. Does it work?
No. Office 365 connector webhooks are retired, and older Workflows links on logic.azure.com stopped working at the end of November 2025. Create a Workflows webhook and copy its new link.
Who does the message come from?
From the workflow, as Teams shows it (usually the Workflows app or the workflow owner). The workflow belongs to the person who created it.
Can I send an image?
Yes, one image per message, in the card below the text. It must be in your Postemi media library.
What is the length limit?
Teams refuses messages over 28 KB. Postemi stops you at 10 000 characters, which stays well under that.
Is there a free trial for Microsoft Teams?
Yes, every new account starts with a 7-day free trial. We ask for a card to start the trial, but we don't charge anything during it. After that the Basic plan is available from $13 a month, and you can cancel anytime.
