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

QuestionPro

Team Edition has a five-seat minimum, so a small team that only needs two or three licences still pays for five.
CX, Workforce and Research Suite are effectively separate products with their own pricing and onboarding, not tiers of the same subscription, which complicates a multi-department rollout.
The free Essentials plan caps at 200 responses per survey, which a single moderately popular customer survey can exceed in days.
The interface is denser than Typeform or SurveyMonkey, and teams that want a fast, visually simple survey builder often find QuestionPro slower to set up.
Enterprise CX and Research Suite pricing is never published, so budgeting for a programme rollout requires a sales conversation before any commitment is possible.

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.

QuestionPro: Is the free plan actually usable long-term?

Yes. Essentials has no time limit, but it caps at 200 responses per survey and one user, which rules it out for anything with meaningful reach.

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.

QuestionPro: Is QuestionPro CX the same product as the survey builder?

No. CX is a separate product built for closed-loop customer experience programmes, priced and sold on its own.

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

QuestionPro: Does Team Edition have a minimum seat count?

Yes, five seats at roughly $83 per user per month billed annually, so the minimum monthly spend is around $415.
