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
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
