The platform

Everything your domain needs, run by people who do only email.

Mailboxes, routing, authentication and reputation on infrastructure we own end to end. No shared pools, no guesswork, no tickets that sit for a week.

Deliverability engineering

Dedicated IPs with automated warmup, live inbox-placement monitoring, and seed-list testing against every major mailbox provider.

Authentication, handled

SPF, DKIM, DMARC alignment, MTA-STS, TLS-RPT and BIMI configured, published and monitored for drift — so you never fail a check silently.

Encrypted end to end

TLS 1.3 in transit and AES-256 at rest, with optional zero-access encryption so not even our operators can read stored mail.

Your domains, your rules

Unlimited domains and aliases, catch-all routing, role accounts, and per-team policy — administered from one console or the API.

Migration without downtime

Parallel IMAP sync from Google Workspace, Microsoft 365, Zimbra or on-prem Exchange. Cut over when history is fully mirrored, not before.

Compliance built in

SOC 2 Type II, ISO 27001, HIPAA BAA and GDPR data residency in the region you choose, with immutable audit logs and legal hold.

Deliverability

Reputation is infrastructure. We treat it that way.

Most providers put you on a shared pool and hope. zip gives your organization dedicated sending infrastructure, warms it correctly, and watches every signal that decides whether mail reaches the inbox.

Automated IP warmup that ramps volume on a schedule tuned to your history, never tripping rate limits.
Feedback loops and spam-trap monitoring across Gmail, Outlook, Yahoo and Apple Mail, surfaced before they cost you.
Reverse DNS, PTR and consistent HELO provisioned per IP, because the small signals are the ones that sink you.

Onboarding

White-glove migration, cut over in three moves.

A named deliverability engineer runs the whole move with your IT team. Your people keep working the entire time.

STEP 01

Provision & authenticate

We stand up your mailboxes, allocate dedicated IPs, and publish SPF, DKIM, DMARC and MTA-STS records with you before a single message routes.

STEP 02

Mirror in parallel

Full IMAP history syncs from your current provider in the background — folders, flags and calendars intact — while the old system stays live.

STEP 03

Flip the MX record

When the mirror is verified complete, we cut MX over during your window. Rollback stays one DNS change away for 30 days.

Security & compliance

Audited, encrypted, and yours to prove.

The controls your security review will ask for, documented and ready. Data residency you choose; audit logs you can export.
