A channel signature that appends itself to every post
What belongs in an automatic signature, why it eats the character limit, and what happens in a private channel.
A tail like “Subscribe: @channel” gets copied from post to post until it is forgotten. An automatic signature solves that at the channel level: the text is appended when the post publishes.
What belongs there
Three things work:
- A link to the channel — for posts that get forwarded. A reader in someone else’s chat should see where this came from.
- A rubric hashtag — if people search by it:
#breakdown,#digest. - A short call — “Questions go to the tip line”, with a link to your persona.
What does not work: long disclaimers, three links in a row, and anything readers scroll past without looking.
About the limit
The signature counts toward the message limit: 4096 characters for text, 1024 for a caption under media. Two hundred characters of tail are two hundred characters the post will not get.
A decent scheduler counts that in advance and warns before publishing rather than after Telegram refuses.
Private channels
A signature usually holds a placeholder like “{link}” that expands into the channel address. A private channel has no public link — so the signature should collapse cleanly instead of leaving “Read us at “ with a dangling tail.
Formatting
The signature is part of the message, so bold, italics and links work.
Mind the angle brackets: “
Setup lives on the scheduler page.
