Spintax creates multiple wordings of the same sentence so that no two recipients receive an identical email. Sending hundreds of byte-identical emails is a strong spam signal — spintax breaks that pattern.
How spintax works
Spintax uses curly braces and pipes to mark alternatives:
`` {Hi|Hello|Hey} {{firstName}}, {I noticed|I saw} you're {leading|heading up} sales at {{companyName}}. ``
Each recipient gets one randomly chosen option from each set, so the same template produces many different emails.
Generate spintax automatically
Write your email normally in the editor.
Click the AI Spintax Generator button in the editor toolbar.
Your subject and body are converted into spintax format in one step, with alternatives added throughout.
Review before sending
Always read the generated spintax before launching:
Check that every combination reads naturally. A machine-generated alternative can be grammatically fine but sound wrong.
Make sure the alternatives are genuine synonyms and don't change your meaning.
Confirm the tone is consistent across variations.
Keep variables outside the brackets
Personalization variables should sit outside spintax braces:
✅ {Hi|Hello} {{firstName}}
❌ {Hi {{firstName}}|Hello {{firstName}}}
Keeping them separate is easier to read and avoids mistakes when editing.
Best practices
Vary the opening and closing lines most — these are the most repeated parts of a cold email.
Two to three alternatives per set is plenty. More adds complexity without improving deliverability.
Don't spin your core message. Your value proposition should stay consistent so you can tell what's working.
Send yourself several tests to see different combinations before launching.
Spintax and deliverability
Spintax helps with pattern detection, but it's not a substitute for the fundamentals: a warmed-up mailbox, a validated list, conservative daily volume, and a genuinely relevant message. Use it alongside those, not instead of them.
