transactional email you can prove
Every email your application sends is a promise.
Here it leaves signed, arrives tracked, and leaves a record. Sending, inbound, reputation and policies on one platform — and when you decide to bring over what already lives at your old provider, the import is read-only, and rolling back is one click.

01 · The problem
You already know how this goes.
The email goes out. The customer says it never arrived.
Someone opens the provider dashboard, searches for the address, and finds a bounce code that explains nothing.
Meanwhile the access code never landed, the invoice went past due, and support answers “check your spam folder.”
None of this is a tooling problem. It is the absence of infrastructure that tells the truth — and keeps telling it when your volume doubles.
Notice something: you don’t need another pretty dashboard. You need to know, right now, what happened to that one message. And while reading this sentence, you probably remembered one.
02 · How it works
Three steps — and the first takes less time than reading this page.
step 1
You connect your domain
The wizard tells you exactly what to publish in DNS and checks it live, on every visit. Leave halfway through and you come back to the step you were on — it doesn’t store a “current step”, it derives it from what is already published.
step 2
Your application sends
HTTP API or SMTP, your choice. One message to five recipients is one message with five outcomes — never flattened into a single field.
step 3
You see what happened
Delivered, bounced, blocked — with the reason in plain language, a signed webhook hitting your server, and the recipient’s reply coming back through the same house.
03 · Platform
What you get here — and what almost nobody ships together.
Inbound that is actually inbound
Point your MX and create named mailboxes or a catch-all. Each one delivers wherever you want: signed webhook, forwarding to another address, Telegram or Slack — and Discord soon. A webhook is only saved after your endpoint answers a challenge — pointing mail at a third party who never said yes doesn’t happen here.
Migration with a way back
Bring suppressions, domains and webhooks from SendGrid or Postmark. Everything is read-and-copy — nothing is switched off at the source, and the credential you paste is not kept afterwards. The cutover is yours, per domain, with a one-click rollback. And what you brought is never deleted on the way back.
Policies that hold at send time
Block a destination, allow only a list, force transactional. Rules run at send time, not in a report afterwards — and there is a simulator that calls exactly the same evaluation, so you enable with confidence instead of faith.
Reputation as routine, not as a fire drill
IP warmup with its own curve, counting the days you actually sent — not calendar days. Pools and a dedicated IP when it makes sense — with the warmup curve handled by us, not by you.
Suppressions with compliance built in
Bounced, complained, unsubscribed — each with scope and origin. Complaints cannot be deleted: not from the dashboard, not through the API, not by deleting the domain and re-adding it. And your list leaves here whole, whenever you want, in a format any provider accepts.
An audit trail that means it
Who did it, when, and what changed afterwards — including when the “who” was our support. Every action with an owner and a timestamp, in a log you read and filter without opening a ticket.
NPS and CSAT surveys, inside the email
The score is the click: the recipient answers in the message itself, no form to open. You trigger it from the API at the moment that matters — after the delivery, the support reply, the purchase — and read the answers and comments in the portal. Bots and link scanners never vote for anyone, and on the first day of every month a PDF report lands in your inbox.
Signed event webhooks
Accepted, delivered, bounced, complained — each one arrives at your endpoint as an event signed with HMAC-SHA256 and a timestamp, so your system knows what happened to every message without polling. Retries, idempotency and the raw body to verify: the plumbing you would otherwise write yourself.
DMARC and TLS-RPT reports, read for you
From Business up, we receive the aggregate DMARC and TLS reports for your domains and turn them into something readable: who is sending as you, what is passing, what is failing and where. The XML nobody opens becomes a page you check in a minute.
04 · Solutions
Built for senders whose email the recipient is waiting for.
We are not a campaign platform. We work with senders whose messages people open because they need them — and that is why our reputation can carry yours.
Fintech & payments
What you send: access codes, receipts, statements, payment notices.
What hurts today: a two-factor code that takes three minutes is already useless. And when it lands in spam, it becomes a support ticket and eroded trust.
What changes here: a dedicated IP with proper warmup, a policy that blocks disposable domains, and a per-recipient outcome so you can prove what left and when.
Healthcare: clinics, labs, telemedicine
What you send: appointment confirmations, exam prep, results-ready notices.
What hurts today: the message is sensitive, the recipient is a layperson, and nobody knows it didn’t arrive until the patient doesn’t show up.
What changes here: plan-based log retention, a trail of who accessed what, and inbound so the patient’s reply comes back through the same channel — no stray mailbox on a front-desk computer.
B2B SaaS
What you send: team invites, password resets, system alerts, invoices.
What hurts today: the invite never lands and your new customer stalls on day one. The critical alert drowns in the inbox.
What changes here: API and SMTP on the same platform, a signed webhook per event, templates whose variables are validated on save, and inbound mailboxes that become webhooks on your server.
Logistics, orders & delivery
What you send: confirmations, tracking codes, delivery windows, failed-attempt notices.
What hurts today: high volume, short deadlines, and a provider that charges per tracking event. When reputation drops, everything drops together.
What changes here: predictable pricing for volume, automatic suppression of hard-bounced addresses, and a one-click satisfaction survey inside the delivery email itself.

Start with the domain you already have — or bring over what already lives there.
Both paths end in the same place. The first takes a few minutes; the second is pure reading, switches nothing off at the source, and rolls back in one click if you change your mind.
You can keep living with the doubt on every send. Or you can, today, send the first email you can prove arrived.
A thousand emails a month, no card, no expiry date.
