Spintax

Also called: Spin syntax, Text spinning

Spintax is a notation for writing alternatives inside an email, such as `{Hi|Hello|Hey}`, so each recipient gets one of the versions.

How it affects cold email

Large campaigns of identical emails look like bulk mail. Small variations in greetings and phrasing make each email a little different. Spintax doesn’t make a bad email good, and it should never be used to disguise what an email is.

How Inboxed handles it

  • Write {option one|option two} in a subject or body. Inboxed picks one option per lead and step, seeded so a retry sends the same words, and nests up to 5 levels ({Hi|Hello {there|friend}}). Options can be weighted ({Hi::3|Hello::1}) or empty ({|really }), and [[A.|B.|C.]] shuffles sentences (`[[sep=
  • |a|b|c]] for lists). {{variables}} and their |fallback pass through untouched, and \{, \}, \|, \[ and \]` give literal characters. The editor previews the variations and their similarity; broken spintax blocks launch in the content scan, which explains the first problem it finds.
