Follow these steps to complete the setup.
Understand the basic Spintax syntax
Enclose your variations inside curly brackets separated by pipe characters: {Option 1|Option 2|Option 3}. For example: {Hi|Hello|Hey} {{firstName}}.
Add variations to your subject lines
Create 3 to 5 variations of your subject line, such as: {Quick question about {{company}}|Quick thought for {{company}}|Brief question regarding {{company}}}.
Spin your introductory hook and value proposition
Vary your opening sentence: {I noticed your recent expansion into|Saw your announcement regarding|Loved your recent update about} {{industry}}.
Vary your Call to Action (CTA)
Test different low-friction asks: {Open to a 5-minute chat?|Worth a brief conversation this week?|Are you open to exploring this?}.
Preview and verify syntax in OutSends
