Where each one falls short

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

Postmark

  • Free tier caps at 100 emails per month with no overages allowed
  • Basic plan ($15/mo) includes 10,000 emails then charges $1.80 per 1,000 extra; Pro and Platform tiers have their own lower per-1,000 overage rates ($1.30 and $1.20), so cost scales per email beyond the included volume
  • Custom high-volume pricing above the published tiers requires contacting sales

Whatagraph

  • The entry Max plan starts at 699 EUR per month and is billed annually, with no monthly billing option shown
  • Only two plans exist and the Prime plan is custom priced with no published rate
  • Public API access, transfer to BigQuery and Looker, a custom report domain and premium integrations all require the Prime plan
  • Data sources are metered as credits at 1 credit per connected data account, so each additional ad account consumes quota
  • Extra credits can be bought only up to the next plan threshold, after which an upgrade is required
  • Moving to either the Max or Prime plan requires booking a call with sales rather than self-serve upgrade
  • The free trial is 14 days
