You send the mail. We keep the record.
Every plan connects the mail server you already have — yours, or SES, Mailgun, Postmark. We never send as if the mail were ours. You keep the reputation. We keep the searchable log.

Transports: any SMTP server (Amazon SES over SMTP included), plus Mailgun and Postmark. Webhook evidence like Delivered appears only when the provider reports it. Plain SMTP reports to the handoff, and never shows a delivery it can’t prove.SMTP · nowMailgun · nowPostmark · now
“How long until this works?”
Under five minutes, honestly. No migration, no DNS change, no new sending domain — your mail server already works. Spoolway sits in front of it.
01Add your mail server — one test checks the host, the password and the encrypted connection.02Import or write a template — git-versioned, shared across your apps.03POST one message — that’s the whole integration. →

Fair question — you pay us and your mail provider. That is not paying twice for the same thing. A bundled sender’s price includes delivery, which you are buying anyway. We charge for the layer they do not sell: one template set across every product, a tag on every email for which product sent it, and a log that does not belong to your sender.
Run the numbers at real volume and the gap mostly closes. What does not close is the exit: switch providers and you keep every template, every record, every integration. With a bundled sender, the log and the reputation live inside the vendor — leaving means starting the record over.

Switch ESPs any time — templates, records and integrations come with you. The archive survives the divorce.BUNDLED ESP · SAME VOLUME
Delivery + templates + archive, one vendor$60–140
One bill, and often excellent delivery tooling. But the templates, the record and the reputation live inside the vendor — the price of leaving is the archive.The honest parts are on every plan.

Shortening retention never deletes what you already have: it applies forward only. Bodies already stored keep the expiry they were given when they were written, and the change is recorded in your audit log. Cancelling works the same way — never a silent wipe.Details ↓

The awkward questions, answered on the page
BILLING
One email you ask us to take = one message, counted when we accept it. If we retry or delay that same email, it is not counted again. A blocked address still counts (we did the work and wrote it down). A refused request does not.
YOUR DATA
The downgrade always proceeds. Caps clamp immediately so the next send, Application or invite is measured against the new plan. Rows already over the line stay — they remain usable and editable, and creating another is refused until you are under the new cap or you upgrade. Retention applies forward only: bodies already stored keep the expiry they were given when they were written. Cancelling returns you to Free the same way. Nothing is deleted because of a price change.
Your transport. Your record.
