Where each one falls short

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

Invoca

  • Entry pricing commonly starts around 1,500 US dollars a month before call minutes, plus a setup and training fee, which prices out agencies and small businesses that only need attribution for a few hundred calls.
  • Telephony minutes and tracking numbers are metered separately from the platform fee, so a seasonal advertising spike produces an invoice nobody forecast.
  • Signal AI, PreSense and quality management are frequently sold as add-on modules rather than included, meaning the demo you were shown may cost noticeably more than the quote you were given.
  • Contracts are annual or multi-year with usage minimums and no month-to-month option, so a campaign strategy that shifts away from phone calls leaves you paying for capacity you no longer use.
  • The product is deep on inbound phone attribution and shallow elsewhere; if your buying journey also involves chat, forms and in-store visits, Invoca covers only one channel and you still need a separate attribution model for the rest.

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

Answered from the vendors’ own pages

Invoca: Does Invoca publish prices?

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.

Invoca: Is this different from CallRail?

Yes, in ambition and price. Invoca targets enterprise attribution with automated outcome classification fed back to ad bidding; lighter call tracking tools stop at source attribution.

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.

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.
