Tips for Using Spintax Effectively
Use spintax for the opening line — it has the most impact on uniqueness detection.
Create 3-5 options per spintax group for meaningful variation.
Keep variations natural. Every option should read well in context.
Don't spintax proper nouns, personalization tokens, or your CTA.
Combine spintax with mail merge variables ({{First Name}}) for maximum uniqueness.
Test all variations before sending — one bad option can hurt your entire campaign.
Use spintax in subject lines too for better deliverability at scale.
Aim for at least 50+ unique variations per email to avoid duplicate content filters.

Spintax Alone Won't Save Your Deliverability
