Open Settings → Business → Inbox → Signature. Check that you have selected the right business.
Use the Default tab to write the signature shared by your connected inboxes. Save your changes. Leave it empty if you do not want a shared signature.
Open Channel override and choose the configured inbox, such as Email: Finance or WhatsApp: Support.
Choose one of these options:
Click Save changes. Two inboxes on the same channel can have different signatures.
The signature appears in the reply field for email, WhatsApp, SMS and Telegram. Review it with the rest of your message. You can change or remove it for that reply. Sending does not add it back.
Automatic AI replies add the saved signature separately. For long SMS and WhatsApp replies, Boei leaves space for the signature when shortening the answer. If the signature leaves too little room for an answer, Boei sends the answer without it and records a warning for support. Use a short signature for these channels.
The AI writes an email greeting in the reply language. The first reply can briefly thank the customer and recall their question. Later replies continue the conversation without repeating that welcome. Messaging replies do not get a formal email greeting.
Signatures keep their saved wording and language. They are not translated automatically. Open Available variables for fields such as the sender or business name.
