Transactional email limits and allowance

• At 90% of allowance, Eza warns Organisation Owners.
• Eza allows one 10% grace period each billing cycle.
• After allowance, grace and purchased packs run out, sends return email_limit_reached.

• An extra 20,000-email pack costs KES 500.
• Buy packs in Billing → Add-ons or with the CLI.
• Eza sends an M-Pesa prompt only after you start the Pay action. Credits become available after M-Pesa payment confirms.
• Packs are used after the plan allowance.
• A pack expires at the end of the billing cycle after the one in which you bought it.
• No automatic email top-up exists.

For the first 14 days, Organisations receive one-quarter of standard sending limits.

Over-rate-limit requests return HTTP 429 with a Retry-After header.

• Attachments are supported up to 10 MB per message after encoding.
• Executable and similar high-risk file types are blocked.
• Message bodies and attachments are deleted after 72 hours.
• Delivery records remain available for 30 days.

• Hard bounces are suppressed for the Organisation for 90 days.
• Remove up to 20 hard-bounce suppressions per day through the dashboard or API.
• Complaint suppression remains until removed. Removal needs a support request with evidence that the recipient agreed to receive the message.
