Where each one falls short

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

Klaviyo

  • The free plan caps active profiles at 250 and sends at 500 emails a month
  • Pricing scales with stored profile count rather than with messages sent, so an unengaged list costs the same as an active one
  • SMS is metered separately, with only $5 of mobile messages included on the free plan
  • Paid tier prices are not published on the pricing page and depend on profile count

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
