Pros and cons
Postscript
Pros
- Low published per-message rates, with carrier fees passed through at cost
- Deep Shopify integration, including sign-up at checkout
- No contracts, no prepaid credits that expire, no overages
- Documented quiet hours handling by state, held until waking hours
Cons
- Shopify only: no use for salons, clinics or non-Shopify stores
- $49 monthly minimum on Starter, and the page does not explain how it counts against usage
- The AI features sit on a $699/month plan
- Email is announced but still on a waitlist with no published price
Klaviyo
Pros
- SMS and email share one profile, one flow builder and one report
- Free plan includes $5 of mobile messages each month to test SMS
- Toll-free number included, with carrier fees built into the rate
- Quiet hours settings documented in detail, including per-flow controls
Cons
- Current US per-message SMS rates are only visible inside the account
- SMS is an extra purchase on top of the email plan
- Overkill if you only want to text customers and never send email
