Email Pricing

Overview​

uSpeedo Email Sending service adopts a Monthly Progressive Tier Pricing model with Tier Carry-Over, where:

  • Pricing is based on monthly email sending volume
  • Usage is billed incrementally across defined pricing tiers
  • Each new billing cycle inherits the pricing tier achieved in the previous month

Pricing Tiers for Sending Emails​

All pricing shown here is calculated per 1,000 emails sent (USD); when each email is sent, the charge will be calculated as the price divided by 1,000.

Monthly Volume RangePrice per 1,000 Emails (USD)
First 100,000$0.35
100,001 – 500,000$0.32
500,001 – 1000,000$0.30
1,000,001 – 2,000,000$0.27

Billing Model​

Progressive (Tiered) Pricing​

Email usage within a billing cycle is billed using a progressive tier model, where each usage segment is charged at its corresponding tier rate.

  • Pricing tiers are applied sequentially as usage increases
  • Each portion of usage is billed independently at its tier price
  • There is no retroactive repricing of previously billed usage

Billing Cycle​

  • Billing is calculated on a calendar month basis (UTC)
  • Usage is accumulated in real time
  • Charges are finalized at the end of each billing cycle

Tier Carry-Over Mechanism​

Starting from the second billing cycle, pricing will inherit the tier achieved in the previous month, referred to as the Starting Tier.

Rules​

  • The total volume sent in the previous calendar month determines the Starting Tier of this month

  • In the new month:

    • All usage up to the upper bound of the Starting Tier is billed at that tier’s unit price
    • Once usage exceeds that threshold, pricing continues progressively into higher tiers

📒 Example​

If a customer sends 1,200,000 emails in Month 1, they fall into:

→ Tier: 1,000,000 – 1,999,999 ($0.27)

Month 2 Billing:​

  • First 1,999,999 emails → billed at $0.27
  • 2,000,000 – 4,999,999 → billed at $0.24
  • ≥ 5,000,000 → lower price

👉 Earlier lower tiers (e.g., $0.35 / $0.32 / $0.30) are skipped, ensuring customers receive the better price.

First Month Exception​

  • In the first billing cycle where no previous billing month exists, all customers start from the base tier (lowest volume tier)
  • Standard progressive pricing applies from the beginning
