Zoho Mail for Deliverability, Migrations, and Security

It is a monthly service. We run your company email inside your own Zoho account: migrating the mailboxes, configuring the domain records, keeping your mail out of other people's spam folders, enforcing security and retention settings, and handling daily administration as staff join and leave. The account, the domain, and the data stay yours. The work and the accountability are ours.

Yes, and it is the most common reason companies call us. Messages, folder structure, contacts, and calendars all come across in batches behind a sync window, so nothing arriving mid move is lost, and mailbox counts are verified before we touch the MX records. The old platform stays reachable until the new one has proven itself, and then we help you close it down.

One to three weeks for most small and midsize companies, from first call to old platform shutdown. The data transfer itself is usually a few days and runs in the background while everyone keeps working. Very large mailboxes, long archives, and source platforms with throttled export limits all add time. You get a schedule up front rather than a range to interpret.

No. The sync window captures anything that arrives mid transfer, and your MX records do not point at Zoho until the mailboxes are populated and verified. If something goes sideways anyway, the old platform is still live and the change reverses. That rollback path stays open until you tell us the new setup is working.

Very little, by design. Because the data is already copied and checked, the switch is a change to where new mail is delivered. What people do notice is their devices: Outlook or a phone that must be pointed at the new account. We schedule the cutover for a time that suits you and have those devices ready, so the first morning is about work, not about setup.

Usually it is one of four things: an SPF record missing a sender, unsigned DKIM, no DMARC policy at all, or leftover records from a previous provider that now contradict each other. Occasionally a compromised mailbox is sending as you. We work out which, fix the records, chase any blocklist delistings, and keep reading the reports so it stays fixed.

They are DNS records that prove mail claiming to come from your domain really does. SPF lists who may send. DKIM signs the message. DMARC tells a receiving server what to do when a message fails one of the other two. You need all three, because the major providers now filter or reject unauthenticated mail from business domains.

Turning enforcement on first would reject legitimate mail from any system that was never added to SPF, such as the billing platform or the newsletter tool. So DMARC begins in monitoring, the reports show every source sending as your domain, and we fix the stragglers. Once the reports come back clean we move the policy to enforcement and keep reading them.

Yes, at whichever registrar or DNS host you already use. Cloudflare, GoDaddy, Namecheap, and Route 53 are all familiar ground. We configure MX, SPF, DKIM, DMARC, and autodiscover, confirm propagation, and clear out leftovers from a previous provider that quietly break authentication. The domain and account stay in your name, and every record is documented so none of it is a mystery two years from now.

Yes, when someone configures it on purpose instead of leaving defaults in place. Two factor authentication is enforced. Session and device policies, spam and attachment rules, TLS in transit, and S/MIME where messages need it are set to match how your team works, and we review the audit logs for suspicious logins and forwarding rules. Weak configuration and reused passwords cause most email breaches, not the platform.

Zoho supports HIPAA compliance features on the plans that include them, and Zoho Mail gives you the retention, consent, and access controls GDPR expects. We configure encryption, set retention and deletion rules, restrict who can view or export mail, enable eDiscovery, and document what is stored where for your compliance reviews. Signing a business associate agreement with Zoho is a step you take directly.

The password is changed, active sessions are ended, and group and shared mailbox access is removed. Mail is forwarded or delegated to whoever picks up the work, and the mailbox is archived or converted rather than left open and consuming a license. Done promptly, that closes the most common way back into a company's email after someone leaves on bad terms.

If email is the only Zoho product you touch, any of our plans covers it at the same published price. Most companies running business email are also in CRM, Desk, or WorkDrive, and at three or four apps the Zoho One license usually comes in under those subscriptions stacked separately. We will tell you which side of that line you are on.

You do. The domain, the Zoho organization, every mailbox, and the subscription all sit under your company name, and we work inside your account rather than holding your mail in ours. If you stop working with us, nothing needs exporting or handing back, and our documentation of how everything is configured lets any other provider pick it up without starting over.

All of them. We configure Outlook, Apple Mail, and Thunderbird on desktops, and the Zoho Mail app or the native mail client on iPhone and Android, including app passwords, calendar and contact sync, and shared mailbox access. When someone gets a new laptop or phone, setting it up is part of the service rather than a ticket you file.

A shared mailbox such as billing@ lets several people read and answer one address. A group distributes mail to a list of members, and an alias adds another address to an existing mailbox. We set up all three, keep membership current as people join and leave, and make sure each is covered in your retention and access policies.
