Signatures and daily limits
Two per-inbox settings live directly on each row of the Inboxes list: a signature appended to outgoing emails, and a daily send limit that feeds rotation.
Inbox signatures
Edit signature on any inbox row opens a modal with an Off/On toggle, a plain-text editor, and a live preview.

To stop receiving these emails, unsubscribe here: https://api.forgesend.cloud/unsubscribe?token=exampleThe preview is built from a fixed template: a placeholder campaign body, the signature (if enabled), then the same unsubscribe-footer example used elsewhere in the app — so what you see is the actual stack order, not just the raw text.
Signature validation
Rules are enforced in the UI and re-checked on the server, so a signature can't be saved in a state the backend would reject:
- Maximum 400 characters
- Plain text only — any HTML tag is rejected
- Only
{{name}}and{{email}}are recognized as variables; any other{{...}}placeholder is rejected with "Signature contains unknown variables. Only{{name}}and{{email}}are allowed." - Trying to save the toggle On with empty text is blocked in the modal itself, with "Add a signature or turn it off before saving."
Daily send limits
Each inbox has its own daily limit — a plain number input, 1 to 500, saved with its own Save button next to the send-usage bar on that inbox's row.
New inboxes start at a default limit of 50 sends/day. Raising or lowering the limit takes effect immediately for rotation — the next capacity check uses the new number, there's no propagation delay. The daily counter itself resets automatically at UTC midnight, independent of when you change the limit.
