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

Rocket.Chat

No prices, tier names with numbers, or minimum seats are published anywhere on the pricing page; all three paid editions (Commercial, Government, Defense) route to Contact sales or Contact us
The free community edition is not represented on the pricing page at all, which lists only the three quote-only enterprise tiers
