Spintax Best Practices
Spin phrases, not words
Phrase-level spintax sounds natural. Swapping individual words creates awkward emails that get flagged.
Preserve personalization
{{firstName}}, {{companyName}} and other merge tags are kept intact — never placed inside spin brackets.
Spam-safe by default
Every spin option is checked against 100+ spam trigger words. Flagged options are highlighted with warnings.
More spins = more unique
5 spin points with 3 options each = 243 unique email versions. Heavy mode can generate 500,000+ variations.
