Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Alchemer

  • More expensive than the simple form builders, which is the fair comparison for a short survey
  • The interface carries a long product history and is less immediately friendly than newer tools
  • Advanced logic is powerful and correspondingly easy to misconfigure, and testing a complex survey is real work
  • Named Alchemer since 2020, so much of the searchable material still says SurveyGizmo

Mailgun

  • Free tier limited to 100 emails per day, restricting high-volume use cases
  • Log retention minimal on lower tiers (1 day on Free and Basic plans)
  • Add-on pricing for email validations and extra emails can accumulate quickly for high-traffic users
