Compose
Write responsive HTML and plain-text versions, personalize with merge fields and attach files stored in R2.
Compose, import, schedule and send without a bloated monthly plan. Sakura Mail gives every account an isolated workspace, encrypted contact storage and transparent pay-as-you-go credits.
No complicated tiers, contact-count penalties or hidden feature gates.
Write responsive HTML and plain-text versions, personalize with merge fields and attach files stored in R2.
Upload CSV, paste a list or add contacts manually. Consent source and timestamp travel with each contact.
Send now or choose a future time. Queues fan out safely, while suppression checks happen immediately before delivery.
Track accepted and failed sends, manage unsubscribes and keep a clean audit trail without exposing recipient addresses to admins.
Contact addresses are encrypted before storage. Every application query is scoped to the signed-in workspace, platform-admin reports exclude contact addresses and campaign content, and access-sensitive actions are recorded in an audit log.
Buy credits when you need them. Credits do not expire while your account remains active.
An attempt counts when accepted into the sending pipeline, including a later bounce, because the upstream provider charges for accepted sends. PayPal processing, Workers, storage and database costs are absorbed by Sakura Mail. Taxes may apply.
Normalize, deduplicate and validate before addresses enter your workspace.
Store approved images and files in R2 with size and type controls.
Keep source, status and timestamp alongside every contact.
Unsubscribed, bounced and complained addresses are blocked at send time.
Workspace IDs are enforced in every data path, including files and billing.
Platform analytics show operations and revenue, not recipient addresses or content.
No. You must have a lawful basis and the permissions required where recipients live. Sakura Mail records consent and automatically includes unsubscribe controls, but the sender remains responsible for the list and message.
Contact addresses are encrypted at rest and excluded from platform-admin views. The sending Worker must decrypt each address briefly to deliver scheduled mail. Access is minimized, logged and limited to service operation and legal/security obligations.
Small card and PayPal transactions have fixed processing costs. A modest minimum preserves the $1-per-1,000 rate without adding subscriptions or surprise fees.
No. Cloudflare Email Service currently limits the total message to 5 MiB and up to 32 attachments. The app enforces a 5 MiB file limit and checks the combined size before sending.
No responsible provider can guarantee inbox placement. Domain authentication, list quality, consent, message content and recipient-provider reputation all matter.
