A notification signature is the sign-off added to the end of every message your customers get, for example your shop name and support number. There’s one for email, one for SMS and one for WhatsApp.

Each of your businesses has its own signatures. A message about a job uses the signature of the business the job belongs to.

Open Settings › Documents & printing › Notification signatures. The banner at the top shows which business you’re changing. To change another business, switch business first.

Pick the Email signature, SMS signature or WhatsApp signature tab, click Edit, change the text and save.

Tab What it’s for Longest
Email signature “Added to the bottom of every email.” You can use bold, italics, alignment and links 10,000 characters
SMS signature Added to the end of every SMS 500 characters
WhatsApp signature Added to the end of every WhatsApp message 1,000 characters

Under Available variables, click a detail to add it. BytePhase puts in the real value when it sends:

Variable Filled in with
Business name The name of the business
Support email Its support email
Support number Its support phone number
Alternate number Its second phone number
WhatsApp number Its WhatsApp number

These details come from each business’s Address & contact section.

  • If you empty a signature and save, messages go out with no signature.
  • To change signatures, your shop owner must give you Business Settings › Change settings. Without it, you can only read them.
  • The words of the message itself are in notification templates.
