Where each one falls short

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

Mailjet

  • Free plan caps at 6,000 emails per month with a hard 200 emails per day limit
  • Starter plan is capped at 2,000 contacts; unlimited contacts require the Essential tier
  • Email credits do not roll over and unused emails expire at the end of each billing cycle
  • Essential and Premium plans both cap at 15,000 emails per month for $17 and $27 respectively, so the price increase buys other features, not more volume

Quo

  • Unlimited calling to US and Canadian numbers is subject to a Fair Usage Policy rather than being truly unlimited
  • Starter tier's $15/user annual rate requires prepaying annually; monthly billing costs $19/user, about 27% more
  • The Sona AI agent automation credits are capped at 1,000 free per plan before additional usage is billed
