Write the message once, and each post fills it in.
Merge tags show as chips in the editor. Add bold, italics and links, check the live preview, and send a test message to the channel before it goes live.
Contact values are posted as plain text, so a contact's name can't add formatting or mention your whole channel.
Steady when a lot happens at once.
RadarSend paces posts to about one a second in each channel and retries a failed post up to three times. If a channel falls more than about 15 minutes behind, the late posts are dropped rather than arriving out of date.
Every post is logged with your webhook deliveries, so you can see what went out and what didn't.
