Add-Ons & Overages

Basic is hard-locked to 1 email account — no add-ons available, enforced at the OAuth connection step.

Standard and Pro can add unlimited additional email accounts at $3/account/month.

Overage call minutes are available on Standard and Pro at $5 per 60 minutes, charged as consumed. Users pre-authorize overage in settings and can set a monthly cap or allow unlimited.

Annual billing saves 20% vs monthly across all tiers.

Cost Per User (Average Case)

ComponentBasicStandardPro

Email drafts (GPT-5 mini)~$0.05~$0.21~$1.05

Call screening (gpt-realtime-mini)—~$1.05~$2.40

Telnyx phone number—$1.00$1.00

Telnyx call minutes (inbound)—~$0.38~$0.86

Total Cost Per User (avg)~$0.30~$2.94~$5.61

Gross Margin (avg)94%80%81%

Calls are the only meaningful cost driver. Email drafting cost is negligible at all volumes. Worst-case Pro margin (300 min + 500 drafts): ~76% — within the 70–80% target.
