How it works
Three steps. Then it is just email.
01
Connect your domain
Paste the DNS records we generate. SPF, DKIM and DMARC are written and watched for you.
02
Create your addresses
Type a name, get a full account. Personal or shared, always unlimited.
03
Send with confidence
Reply, campaign, publish. Warm-up, suppression and one-click unsubscribe ride along.
The problem
Company email became four subscriptions and a spam folder.
Now
A bill per seat. A bill per subscriber. A spreadsheet for the list. And no one answering for the spam folder. Every hire and every new reader makes it more expensive, while your audience stays scattered across tools that do not talk to each other.
With LetterDuck
One workspace on your domain. One bill. Mail that arrives. Every teammate gets an address, the list and the newsletter live beside the inbox, and the deliverability work runs underneath, around the clock. That is the whole idea.

DMARCENFORCED+
Policy at p=reject: spoofed mail from your domain gets refused outright. Reports monitored for you.
Warm-upON SCHEDULE+

The standard
What handled actually means.
The Gmail and Yahoo bulk sender rules, running by default on every domain.
Authentication
SPF, DKIM and DMARC published, aligned to your From address, monitored continuously.
Warm-up
New domains ramp volume on a measured schedule instead of spiking.
Suppression
Bounces, complaints and unsubscribes removed permanently, before every send.
One-click unsubscribe
RFC 8058 List-Unsubscribe on every newsletter, honored immediately.
Complaint rate
Tracked against the 0.1% target and Gmail's 0.3% ceiling; sends pause before crossing it.
Content
A plain-text part in every campaign; image-only blasts never leave the building.
Pricing
Fifty dollars. That is the entire pricing page.
$50
per domain
Everything above. One flat price per domain.
Unlimited addresses, contacts, newsletters and deliverability. No seats, no tiers, no surprises.
The eleventh hire is free. So is the fiftieth.
Questions, answered plainly.
What does the plan include?
One domain: unlimited addresses, contacts, newsletters, and deliverability managed for you. One flat price, no tiers, no per-seat charges.
We already pay for a per-seat suite. Why move?
Because the suite covers only the inboxes. Newsletters, lists, campaigns and deliverability still need their own tools. LetterDuck is the whole pile in one place, on your domain, at one flat price.
How hard is setup?
Paste a few DNS records, watch the live check turn green. We generate them for you. Minutes of work, once.
Do I need to understand SPF, DKIM or DMARC?
No. They are published, aligned and monitored for you. If you do understand them, everything is visible in Settings.
I do cold outreach. Will this actually help?
You get what moves inbox placement: authenticated sending, a warmed domain, automatic suppression, complaint tracking. What it will not do is blast a purchased list.
Can my whole team use it?
Yes. Every address is its own account. One per person, shared ones like sales@, and the bill never moves.
When does it launch?
Seats open in waves. You get exactly one email when yours is ready, and nothing else before that.
Reserve your domain's place.
Seats open in waves. One email when yours is ready, and not a word before that.
