Best HIPAA Email Archiving for Clinics in 2027: 3 Steps

Start with the BAA, not the feature list

The category decision comes first. If your practice already runs Microsoft 365 or Google Workspace, start with the archive that platform offers under its own business associate agreement, and add a separate archive vendor only when that native option misses a retention, hold, or export requirement you have written down. HIPAA email archiving is a service that keeps a separate, searchable copy of practice email so you can produce it for audits, legal holds, and retention requests without depending on each staff member's inbox.

TL;DR: confirm that the BAA names the archive product, confirm you can place a legal hold and export a message with its metadata, and only then compare price. Two of the six options below have a published figure we could read in this session, and the rest need a quote or a written answer on BAA scope before their numbers mean anything.

Key Takeaways

• Confirm BAA scope before any other comparison: Microsoft makes its BAA available by default to covered entities, while Google's Cloud BAA lists Gmail and covers Vault only "if applicable."

• Google's Vault archive is listed on the Plus plan and not on Starter or Standard, so for a Google Workspace practice the archive decision is also a plan decision.

• Microsoft's archive grows automatically within limits, but Microsoft does not permit copying messages into archives with journaling, transport rules, or forwarding rules for archiving purposes.

• Mimecast and Barracuda show no archive price on the pages we opened, and neither archive page states a BAA, so both need a written answer before procurement.

• Paubox states that every customer receives a BAA at no additional charge, but its archive sits in the top tier and its prices were not readable on the page.

• Among options with a readable price that list an archive, Hushmail has the lowest readable standing price apart from Google's time-limited introductory rate, but it is a hosted mailbox, so adopting it means a migration rather than an add-on.

Who this is for

This guide is for the owner or operations lead at a small healthcare business who is close to choosing and wants a shortlist with the evidence attached. It fits a practice that stores patient-related email, has to find and hold it on request, and needs either a budgetable price or a clear quote path. Dental offices that run in-house membership plans send recurring patient email, and our dental membership guide covers that workflow separately. Veterinary practices usually sit outside HIPAA, so our veterinary billing guide is the better starting point for that buyer.

Red flags: nobody on staff can name who owns retention settings, you plan to copy all staff mail into individual archive mailboxes on Microsoft, or you intend to treat a vendor's HIPAA assessment as if it were a signed BAA.

How we evaluated these tools

This shortlist rests on public information only: vendor product and pricing pages, Microsoft and Google documentation, the HIPAA Security Rule text, and a published breach-cost summary. We did not buy or run any of these products, so every capability below is a published claim rather than an observed result. The weights reflect our judgment about what hurts a small practice most when it goes wrong. Regulated firms face a similar archive decision, and our RIA compliance archiving guide covers that rulebook.

We weighted BAA scope highest because a low-cost archive that a vendor will not cover under a BAA is a liability, not a saving. We do not total the criteria into one score, because most vendors publish too little for a fair number. Each profile below separates what the vendor publishes from what we think.

Feature matrix: published claims only

Two of the six products do not state a BAA on the archive pages we opened, Mimecast and Barracuda, and Google's BAA covers Vault only "if applicable." That gap decides more than price does, so resolve it in writing before you compare seats.

Pricing: what you can budget and what you cannot

Pricing checked October 19, 2026.

Google's pricing page lists Plus list price: $22.00 per user per month according to Google (2026), effective February 2, 2027, with an $11.00 introductory rate from November 2, 2026 to February 2, 2027 and a Starter list price of $7.00 from February 2, 2027. The footnote limits the introductory rate to a set number of users and months, and its dates do not match that wording, so confirm it with Google before budgeting on it.

Hushmail's healthcare plans start at $11.99 per month according to Hushmail (2026), but that is a per-account starting figure, and plan-by-plan amounts were not readable in our session. Hushmail's pricing page shows a BAA on its healthcare plans and not on its small business or law plans, so the plan name matters.

Paubox's pricing page lists three Email Suite tiers, each covering five senders, and says every customer receives a business associate agreement at no additional charge according to Paubox. Its price fields showed placeholders, so this article prints no Paubox figure.

Microsoft's pricing page did not load during our research, so this article prints no Microsoft list price, and you should check the current figure before budgeting. Mimecast's archive page routes buyers to a "Get a Quote" link and says pricing depends on employee count rather than mail volume. Barracuda's archive page publishes no price.

Rates are the figures cited above; the Google list rates take effect February 2, 2027, except the Google introductory row, and the Hushmail figure is a per-account starting price. Seat counts are illustrative, not a sizing recommendation.

Take an illustrative 12-person clinic that wants Vault for retention and holds. Twelve seats at $22.00 per user per month according to Google (2026) come to $264 per month, or $3,168 per year. Kept for six years, the seat cost alone reaches $19,008 ($3,168 x 6, our arithmetic). The six-year horizon borrows the Security Rule's documentation retention period, according to Cornell Law School LII (current text); treat it as a planning horizon, not a rule for email. Vault is priced inside the Plus seat, so budget the whole seat cost, not a separate archive fee. A Vault admin would place a hold through matters.holds.addHeldAccounts, the Vault API method that adds accounts to a hold, and start an export with matters.exports.create, so the seat list also defines which accounts a hold can reach.

Vendor profiles: where each one fits

Microsoft: Exchange Online Archiving

Archive: 100 GB at start, 1.5 TB cap according to Microsoft Learn (2026), and auto-expansion is supported only for mailboxes that grow no more than 1 GB per day. The same page says Business Premium and E3 already include archiving, while Business Basic and Business Standard need the add-on for auto-expansion and litigation hold, and it says journaling, transport rules, or auto-forwarding may not be used to copy messages into archives for archiving purposes. Microsoft makes its BAA available by default to covered entities and business associates, and Exchange Online is in scope, according to Microsoft Learn (2026), which also says using Microsoft services does not on its own achieve HIPAA compliance.

Our read: this is the fit for a clinic already on Business Premium or E3 with one admin who owns retention. The archive is per user, so it is not a catch-all for shared mail or a multi-tenant group. Implementation means enabling archive mailboxes and setting archive and retention policies in Microsoft Purview, then testing a hold on a test account before you rely on it.

Google: Workspace Plus with Vault

Google's Plus plan lists Vault to "retain, archive, and search data," and its Starter and Standard plans do not list Vault. Google's Cloud BAA lists Gmail and includes Vault only "if applicable," according to the HIPAA documentation we opened.

Our read: this fits a clinic already on Google Workspace that needs holds and search and can budget for the Plus seat. The limit is that Vault is not available on the lower plans shown, and its BAA scope is conditional, so confirm that scope in writing. Implementation means accepting Google's Cloud BAA through its privacy compliance page, setting Vault retention rules, and running holds and exports through the Vault console or API.

Mimecast: Cloud Archive for Email

Mimecast's archive page says the service keeps all inbound, outbound, and internal email and offers a 7-second search commitment according to Mimecast. Its HIPAA page says its offerings passed the HIPAA Security Compliance Assessment, which is not the same as a BAA.

Our read: this fits a practice group with mixed mail systems that wants one archive across them and is willing to go through a sales quote. The limits are a missing price, no BAA statement on the archive page, and export formats the page does not describe. Ask for a BAA that names the archive, a price basis by employee count, and the export format list before procurement.

Barracuda: Cloud Archiving Service

Barracuda's cloud archiving page says the archive is licensed per user with no retention or storage limits according to Barracuda. Its features page describes legal holds that override other retention rules, PST or EML exports at no additional cost, and an audit trail of system activity.

Our read: this fits a clinic that wants a standalone archive with legal holds and PST or EML export and can wait for a quote. The limits are no published price and no BAA on the pages we opened. Ask for the BAA and a per-user quote, and confirm whether the archive will receive mail through SMTP journaling or IMAP and POP3 retrieval.

Paubox: Email Suite, Premium tier

Paubox says every customer receives a BAA at no additional charge according to its pricing page. Per that page, archived email search, view, and export appear only in the Premium tier, which also adds unlimited storage for inbound and outbound email.

Our read: this fits a clinic on Google or Microsoft that wants a BAA-covered encrypted email layer with archive included at the top tier. Budgeting is hard because pricing is per sender and the figures were not readable. Confirm which tier includes archive, the sender count, and whether the archive covers mail that flows through your existing platform.

Hushmail: Healthcare plans

Hushmail's healthcare page describes a signed BAA and a built-in archive for HIPAA compliance, along with a form builder and a starting price per account.

Our read: this fits a very small practice that wants a hosted, BAA-backed mailbox with an archive, not an add-on for an existing tenant. The limits are that its pricing page shows the BAA on healthcare plans but not on small business or law plans, that individual tier prices were not readable, and that moving staff to a new mailbox is a project. Confirm the healthcare tier, account count, migration path, and BAA version before any patient mail moves.

Our first choice is not one vendor for every clinic. Microsoft and Google are the right first look for a practice that already runs their mail, while Hushmail or Paubox make more sense for a practice without a mail platform worth keeping. US Tech Automations is the wrong choice in three cases. A practice with one or two staff who need only an encrypted, BAA-backed mailbox should buy that plan and skip a workflow layer. A clinic already on Microsoft 365 Business Premium that needs only native holds and retention should use the native controls first, because an extra automation layer adds maintenance. A practice that needs a standalone archive with the vendor's own eDiscovery support, and no custom workflow, should buy the archive and stop there.

Three steps to a defensible shortlist

Step 1: get the BAA in writing for the archive, not just the mail platform. Microsoft's BAA is available by default to covered entities, Google's BAA covers Vault only conditionally, and Mimecast's HIPAA assessment is not a BAA. Ask Mimecast and Barracuda for a BAA that names their archive before anything else, and treat any answer that only mentions a general security certification as incomplete.

Step 2: write the retention and hold rules before you configure anything. Ask counsel to set the email retention period and to name who can place a hold. State medical-records rules can require longer periods than the Security Rule's documentation floor, so treat that floor as a minimum for documentation, not as a finished email policy.

Step 3: run an export drill with one sample message before you sign. Confirm the export keeps sender, recipient, timestamp, and hold status, and check that a reviewer can read it without special tools.

A proposed, configurable design for a Google Workspace clinic would start with a hold request logged through a short form. The trigger is the form submission, and the action is a script that calls matters.holds.addHeldAccounts for the named accounts only. The output is a confirmation record with the hold ID, the requester, and the time, sent to the compliance owner. Prerequisites are a Vault admin credential limited to hold actions, a BAA covering every tool in the chain, and a written rule for who can file requests. Human review means counsel approves the scope before the call runs, and any failed call goes to an exception queue for a person rather than an automatic retry. That is a design to configure with US Tech Automations, not a live deployment or a measured result.

The export side follows the same pattern, with an approved matter as the trigger rather than a form. The action would call matters.exports.create for that matter, and the output is an export record that a reviewer checks before anyone downloads or shares it. The prerequisites are the same BAA and a Vault role with export rights. A Microsoft tenant would need a different connector, because this Vault API design does not carry over to it.

Common mistakes and the build-it-yourself option

The costliest mistake is treating a HIPAA assessment or a general security certification as a BAA. The second is buying a plan that does not list the archive feature and then expecting the feature anyway, which is what happens when a practice on Starter assumes Vault is included. The third is copying all Microsoft mail into per-user archive mailboxes, which Microsoft's documentation does not permit for that purpose. The fourth is comparing estimates or reseller figures against list prices. The stakes are real: Breach cost reference: $7.42 million average according to HIPAA Journal (2025), which reports IBM's 2025 average for healthcare-industry breaches.

Zapier, Make, and n8n can build the same logs, retries, and alerts for this design. Configured well, they keep run histories, retry failed steps, branch on errors, and write audit records. You still own the parts that decide whether the archive is trustworthy: idempotency so a message is not logged twice, escalation when a run fails, access controls on who can read patient data in run histories, and maintenance when a vendor changes its API. Confirm each platform's BAA position on your plan before any patient data passes through it. US Tech Automations would configure the same chain with its run log, exception queue, and human sign-off set up in one place, but that is a proposal with the prerequisites above. Whether it costs less than your own build depends on how many hours your staff spend on checks today.

Questions buyers ask before they sign

Does a BAA alone make a clinic HIPAA compliant?

No: Microsoft's own HIPAA documentation says using its services does not by itself achieve compliance, so the clinic still owns its policies, access controls, and logs.

Is Google Vault enough for a clinic on Google Workspace?

It can be, if the clinic is on Plus, because Vault is listed there, but Starter and Standard do not list it and Google's BAA covers Vault only "if applicable," so confirm the scope in writing.

Which option has the lowest readable price for an archive?

Apart from Google's time-limited introductory rate, Hushmail's healthcare plans show the lowest readable standing price among options that list an archive, but that figure is per account and the product is a hosted mailbox rather than an add-on.

Can I copy all Microsoft mail into archive mailboxes?

No: Microsoft's documentation says journaling, transport rules, or auto-forwarding rules may not be used to copy messages into archive mailboxes for archiving purposes.

Can Zapier, Make, or n8n replace an archive?

No: they can run the workflow and keep logs, but the archive itself has to live in a product that stores, holds, and exports the mail under a BAA.

Why is Global Relay not in the ranking?

We could not open an official Global Relay page that describes its archive features or BAA position, and the pricing we found came from resellers, so it stays out until its own pages can be read.

Who should choose Mimecast or Barracuda?

Choose them when you need a standalone archive across mixed mail systems, and ask for a quote and a BAA that names the archive before you commit.

Where to take this shortlist

Start with the BAA question for the mail platform you already run, write the retention and hold rules with counsel, and run an export drill on one sample message before you sign anything. If your team wants a configurable design for holds, exports, and exception review, see how US Tech Automations configures this, and ask for its prerequisites in writing before you commit.
