The short version

  • Each has a real cost: Mailgun free tier limited to 100 emails per day, restricting high-volume use cases; SurveyLegend every paid tier can collect more responses than it can export, with Pro gathering 5,000 per survey but exporting only 1,000 and Business gathering 20,000 but exporting 10,000, so data you have paid to collect can be stranded inside the product.

SurveyLegend

Where each one falls short

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

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

SurveyLegend

  • Every paid tier can collect more responses than it can export, with Pro gathering 5,000 per survey but exporting only 1,000 and Business gathering 20,000 but exporting 10,000, so data you have paid to collect can be stranded inside the product.
  • The free Starter plan cannot export data at all, only preview it in the live analytics, which makes it a demonstration rather than a usable plan and means any real project starts as a paid one.
  • The vendor claims neither SOC 2 nor ISO 27001 nor any third-party audit, and its GDPR page does not disclose hosting location, subprocessors or transfer mechanisms, so an enterprise security review will stall regardless of how good the residency story is.
  • The integration list runs to roughly four connectors with no native Zapier, Make, Slack, Teams, HubSpot or Airtable support, so anything beyond Google Sheets or Mailchimp has to be built against the API, which itself is unavailable below the Business tier.
  • No seat, collaborator or team permission model is documented anywhere in the pricing, features or user guide, so an organisation that needs several people to share and administer surveys has no described way to do it.

Answered from the vendors’ own pages

Mailgun: What happens when I exceed my monthly email quota?

Mailgun allows monthly overage options on paid plans. Extra emails are charged from $1.30 to $1.10 per 1,000 emails depending on plan tier. Enterprise customers negotiate custom rates.

Source
SurveyLegend: Where is my data stored?

In Frankfurt, Germany, on DigitalOcean, on every plan including the free one, with backups also held in Frankfurt. There is no United States transfer and no residency upgrade to buy.

Mailgun: Can I upgrade from Free to a paid plan and when does billing begin?

Yes, you can upgrade to paid plans anytime. The first month is free on Foundation ($35/month) and Scale ($90/month) plans, with billing starting on month two.

Source
SurveyLegend: What is the catch with the free plan?

You cannot export your data. You can build three surveys, collect a thousand responses each and view the analytics, but getting the raw responses out requires a paid plan.

Mailgun: What currencies and billing periods does Mailgun support?

Mailgun supports monthly billing in USD, EUR, and GBP. Charges are prorated for mid-month signups. Annual billing options are not explicitly listed on the pricing page.

Source
SurveyLegend: Why does Pro cost 170 USD a year when the page shows 15 USD a month?

The published annual total is 170 USD, which is ten dollars below twelve times the stated monthly-equivalent rate. Both figures are printed on the vendor pricing page.

SurveyLegend: Is it suitable for an enterprise rollout?

Probably not. There is no SOC 2 or ISO 27001 certification, no documented team or permission model, and support is by email with phone access only on the top tier.
