Products and SaaS
Sign-up confirmations, password resets, receipts, and the notifications your app already sends.
Email for products
CloudySend sends the mail your product already needs: a Resend-compatible API, ordinary SMTP mailboxes, your own domain, templates, webhooks, and a delivery log.
Teams that send mail from a product, not from a personal inbox.
Sign-up confirmations, password resets, receipts, and the notifications your app already sends.
GitLab, WordPress, monitoring, forums, and anything that only knows host, port, and a password.
Segments, templates, and broadcasts to the audience you already have.
The SDK you already use, signed webhooks, and an HTTP log for every API call.
Sending, domains, and the record of what happened — without a second tool.
Keep the official Resend SDK. Point it at CloudySend and send with the same call. Domains, keys, templates, contacts, and broadcasts stay next to it.
Host, port, username, password. Mail from other apps joins the same pipeline as the API.
SPF, DKIM, and return-path, with the DNS records listed on one page. Open and click tracking turn on per domain.
Greylist retries, bounces, complaints, suppressions, opens, and clicks — visible per email.
Workspace limits keep a month of sending inside the number you expect.
Shared keys, mailboxes, and history. Owner, developer, and member roles.
Create an account. A workspace is ready for your domain, keys, and mail.
Publish the DNS records and wait for verification.
From your code, from an SMTP mailbox, or with the button in the dashboard.
Keep the SDK. Change the base URL and the API key from the dashboard. Idempotency, batch send, templates, and webhooks stay on the same path.
