Custom Audience Manager (advanced segmentation)
A/B testing built into campaign builder
Two-way SMS at scale
A2P 10DLC fully managed
Short code provisioning included on most plans
Dedicated CSM, copy support, strategy consults

Pricing

Custom contracts; typically $1K–$10K+/mo platform fee + per-send fees
Annual contracts standard
Pricing rarely makes sense for <50K active SMS subscribers
Negotiable based on volume and tier

When to Use

Mid-market+ DTC brand (50K+ active SMS subscribers, $5M+/yr revenue)
Want dedicated CSM and copy support, not just tooling
Need concierge two-way SMS at scale
Multi-channel ecom team that wants single-pane SMS-first platform
Want short code included rather than separately leased
Identity resolution / cross-device matching matters

When NOT to Use

Smaller brands — too expensive, overkill
Already on Klaviyo and SMS is secondary — Klaviyo SMS is simpler
Shopify-only and want depth — Postscript is more Shopify-native
Custom platform / B2B SaaS — Twilio

Relevant Skills

sms
emails (run alongside)
churn-prevention
customer-research (identity resolution data)
