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

Omnisend

  • Free plan caps at 250 contacts and 500 emails per month
  • Standard plan is limited to 500 contacts and 6,000 emails per month before an upgrade is required
  • SMS is billed separately starting at $0.007 per message and varies by country and volume
  • Custom pricing only begins above 150,001 contacts, requiring a sales conversation at that scale
