While testing emails, it's important to avoid common mistakes such as:
Not testing enough variations: Limiting your tests to only a few variations can restrict your insights. Ignoring mobile testing: Ensure your emails are tested on mobile devices as a significant portion of users access emails via mobile. Insufficient sample size: Testing with a small sample size can lead to unreliable results. Not monitoring deliverability: Failing to check if your emails are reaching the inbox can render your tests ineffective.
