Cold-email infrastructure

Fleets get burned by what they share.

Shared IPs. Shared tenants. Shared nameservers. Shared redirect targets. Filters cluster sending fleets by their common infrastructure — wharf is domain infrastructure built to share none of it.

The four shared surfaces

Every provider isolates at most two of these. Wharf removes all four.

Surface 1 · Nameservers

One isolated NS set per domain

Every wharf domain gets its own Route 53 zone with its own four-nameserver delegation set. Your domains never share a DNS fingerprint — with each other, or with anyone else's fleet. No other provider even mentions nameservers.

Surface 2 · IPs & tenants

We never send your mail

You connect your own Google Workspace mailboxes — your reputation rides on your mailboxes, not a reseller's shared pool or tenant. Wharf never stores a mailbox password; connections hand off via OAuth or app password directly to your sequencer.

Surface 3 · Redirect targets

Masking with no redirect

Masked tracking hostnames serve your site in place — content under the sending domain, HTTP 200. No 301 graph tying every lookalike domain back to one crawlable root.

Surface 4 · Lapsed domains

Auto-renew, enforced daily

Auto-renew is forced on at registration and re-checked every day by a watchdog. You are the registrant — transfer out whenever you like. A lapsed sender domain is how good fleets die.

How it works

Requested → isolated, masked, authenticated, connected.

One durable pipeline drives every domain through the same auditable steps — you can watch each one advance in the console's event log.

Acquire & isolate

Register (or import) the domain into its own Route 53 zone with a distinct delegation set. Auto-renew on, transfer-lock on.

Mask

Stand up masked link hostnames that serve your real site under the sending domain — no redirect, valid cert, done for you.

Authenticate

SPF, DKIM, DMARC and a verified SES identity, written record-by-record. DMARC tightens none → quarantine → reject only when report evidence shows zero legitimate-mail collateral.

Connect

Connect your Workspace mailbox with one OAuth consent (or an app password), hand it to Instantly, and enroll warmup. Raw SMTP export for your own tooling is on the roadmap for every tenant.

We built wharf because our own fleet died. In 2025 a performing sending fleet — eight domains, twenty-eight senders — lapsed at the registrar in a single window. Reputation, warmup, and pipeline gone overnight. Everything wharf enforces — forced auto-renew, daily watchdogs, evidence-gated DMARC — exists because we needed it first.

Founding tiers

Pay for domain infrastructure. Keep your mailboxes anywhere.

Per-domain pricing — not per-mailbox rent. Domains are billed at registrar cost (~$12–15/yr), never marked up. Founding-tier pricing is locked in for founding fleets.
