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

SendGrid

  • Free plan caps at 100 emails per day and expires after 60 days, per twilio.com/en-us/products/email-api/pricing (Aug 2026), after which sending requires a paid plan
  • Dedicated IP addresses are only included from the Pro plan at $89.95 per month; Essentials at $19.95 per month lacks a dedicated IP, per Twilio's own pricing page
