How do multiple CTAs affect click-through accuracy?

Multiple CTAs split attention and complicate measurement. When an email has five buttons, you can't say which one the email was "about." Total clicks might be high, but the signal is muddy-did people click what you wanted, or whatever was nearest?

Measurement challenges: Attribution complexity-which CTA drove the conversion? Diluted primary action-lower clicks on your main goal. Misleading metrics-high total clicks mask low conversion on the important action. A/B testing difficulty-hard to know what drove improvement.

Fewer CTAs mean cleaner data. Single-purpose emails tell you clearly: did this message work? Multi-CTA emails require more sophisticated tracking to understand behavior. If you need multiple options, establish clear primary/secondary hierarchy and track each distinctly. But question whether complexity serves your goals.
