Spintax - effortlessly generate on-brand, compliant copy —faster and at scale.

Spintax generates multiple wordings of the same message using bracket-and-pipe syntax — for example, {Hello|Hi|Hey} randomly resolves to one option per send. Adaptix’s Spintax engine goes further, using AI to produce context-aware, human-sounding variations rather than simple word-swapping, so each version still reads naturally.

Every variant runs through Adaptix’s brand guardrails: a “do not say” list blocks off-brand phrasing, mandatory legal language and disclaimers are auto-injected, and region-based phrasing swaps keep messaging compliant across markets. Tone packs (helpful, direct, educational, urgent) are pre-approved, so no rotation can drift outside brand.

Sending identical copy across thousands of emails increases spam filter triggers and complaint rates. Spintax rotates variants with usage caps and holdouts so no single line gets overused, reducing repetition-based spam flags. Adaptix’s own testing shows a 5–15% improvement in open rates and better inbox placement over time.

Yes. Spintax supports different variant sets per segment — trial users, churn-risk accounts, and VIP buyers can each receive different tone and urgency levels, with copy automatically softened for low-intent segments and intensified for high-intent ones. A segment preview shows exactly what each group will see before you send.

Track deliverability rate (target 95%+), open rate, response rate, and spam complaint rate. Run a baseline campaign without Spintax, then a comparable campaign with it, and compare the two. Most teams see a 5–15% lift in open rates and improved inbox placement as rotation reduces repetition flags.

Avoid over-spinning (six-plus options in one bracket reads as robotic — three is the sweet spot), mismatched synonyms that change meaning or tone (e.g., “I wanted to” vs. “I demand to”), and mixing formality levels within the same variant set (don’t pair “Dear Sir” with “Hey dude”). Keep every option in a bracket consistent in tone.

Spintax is included as part of the Adaptix platform at no added cost — it’s one of the built-in AI tools available alongside Brand Kit and Memory, Send Time Optimization, and the Subject Line Helper.
